Job Description

Gtmhub is the world’s most beautiful and intuitive Objectives and Key Results (OKRs) management and employee experience solution. We build enterprise-scale software with a consumer-grade experience.

We help organizations amplify revenue growth by aligning every employee with their corporate purpose using the OKRs method. We are big believers in the power of employee experience to drive productivity, so our product facilitates best practice employee success features.

At heart, we are product people who love data so much that we built the only solution that integrates more than 150 data connectors to allow for true automation of progress and productivity management.

The Role

The term site reliability engineering is credited to Benjamin Treynor Sloss, Vice President of Engineering at Google. He said site reliability engineering is “what happens when a software engineer is tasked with what used to be called operations.”

To us, a Site Reliability Engineer (SRE) is responsible for the availability, latency, performance, efficiency, change management, monitoring, emergency response, and capacity planning of their services.

SREs design and implement automation with software to replace human labor. They want systems that are automatic, not just automated—such that their services are able to run and repair themselves.

Responsibilities

Engage in and improve the entire lifecycle of services—from inception and design, through to deployment, operation, and refinement/system tuning

Support services before they go live through activities like system design consulting, developing software platforms and frameworks, capacity planning and launch reviews

Maintain services once they are live by measuring and monitoring availability, latency, and overall system health

Identify performance bottlenecks and troubleshoot performance issues

Scale systems sustainably through mechanisms like automation, and evolve systems by advocating for changes that improve reliability and velocity

Practice sustainable incident response and postmortems

Basic Qualifications

Experience with algorithms, data structures, complexity analysis, and software design

Ability to work across teams (business and technical) to continuously analyze system performance in production, troubleshoot consumer reported issues, and proactively identify areas requiring optimization

Preferred Qualifications

Expertise in designing, analyzing and troubleshooting large-scale distributed systems

A systematic problem-solving approach, accompanying effective communication skills, a sense of ownership, self-direction, and drive

Ability to debug and optimize code and to automate routine tasks

Practical experience in supporting application reliability practices for consumer-facing web and mobile experiences

The Stack

Our tech stack includes (but is not limited to):

Kubernetes, Docker, Golang, Java, GAP, ELK, OpenTracing, Python, OpenShift, Terraform, Ansible

We started in Sofia in 2015 with a mission to ship a world-class data management and analytics engine which allows companies to automatically track and visualize KPIs in real-time and create custom insights to inform goal setting, performance management, and long-term strategic decision making. Today we operate across offices in Sofia, London, Berlin, and San Francisco.

Apply today if our mission inspires you! Join us in developing yourself and others as our Site Reliability Engineer.

Job Description

At Monzo we’re aiming to build the best current account in the world. We are always keen to hear from capable, creative engineers who want to help us accomplish that goal 🚀

We’re currently looking for Site Reliability Engineers (SREs) to join our Platform team.

We’re looking for SREs who are software engineers at heart - you’re as comfortable writing software to solve problems as you are operating AWS or Kubernetes. If you’re a software engineer who has some good cloud infrastructure experience already, or you’re eager to get really familiar with systems, tooling and libraries, this could be the role for you.

As a team, we’re responsible for designing, building, and operating the services we consume from AWS, along with the software we run on top like Kubernetes, Cassandra, Prometheus, and Kafka. We’re also responsible for operating our three physical data centres, our network, and being on-call for the things we own and run.

To achieve this, we’re organised into three squads within the Platform Group; Infrastructure Platform, Storage Platform, and Backend Platform. Each squad is responsible for solving a specific set of problems for our customers and our engineers. We’re looking for engineers who are interested in joining our Infrastructure Platform or Storage Platform squads right now, but there are opportunities to move between them as you gain experience with our platform.

We've posted a good overview of our platform on our blog if you’d like to learn more.

We're investing a lot of up-front effort in building a scalable, secure, and extensible architecture for our millions of customers. Come and help us build a state-of-the-art microservices platform and build the kind of bank you want to use.

Our engineers have a variety of different backgrounds

We have several non-graduates; only some of us studied Computer Science; some of us have worked in huge companies; some have only ever worked in startups; others are former consultants. As long as you enjoy learning new things, we’d love to talk to you. We do not ask for formal qualifications or degree requirements for any of our engineering roles.

We are actively creating an equitable environment for all of our engineers to thrive

Diversity and inclusion are a priority for us and we are making sure we have lots of support for all of our people to grow at Monzo. We provide a sponsorship framework in Engineering for women and people of colour; all of our leaders are trained on privilege awareness and we are creating partnerships with organisations dedicated to supporting underrepresented groups. You can read more in our 2020 Diversity and Inclusion report.

Monzo works in project-based sprints in small, interdisciplinary teams

We have around 150 engineers out of roughly 1,400 people in total - and we have big ambitions. There are many interesting challenges ahead, and we're happy for people to move between teams or to specialise, whatever you prefer. As an engineer here you'd be able to work directly with anyone across the company, and we run regular knowledge-sharing sessions so you’ll learn heaps about everything from how banks work to effective communication.

We encourage an open and transparent working environment

You can get involved in any aspect of the business you are interested in and, following Stripe’s example, all emails in the company are visible in an email archive. We contribute to open source software as much as possible. We’ve also made our product roadmap public and give sneak peeks of features in our community forum. Our technology blog is a good place to learn even more about what we do!

At Monzo you will get to work with a lot of exciting new technology.

We rely heavily on the following tools and technologies:

• Go to write our application code (we also use Go to write software to control and manage our platform)
• AWS for most of our infrastructure
• Kubernetes to schedule and run our services (Chris, our Technical Director of Platform and Reliability and Suhail, a Staff Engineer in our Platform Collective gave a great talk recently at re:Invent sharing an overview of our platform)
• Prometheus to monitor everything! (see How we Monitor Monzo)
• Envoy Proxy for our Service Mesh
• Kafka for our asynchronous message queue
• Cassandra for most persistent data storage
• We also have three physical data centre sites with a number of leased lines to connect our cloud infrastructure to various payment systems

You should apply if:

Our open roles are for mid-level to senior Site Reliability Engineers at present. Apply if:

• the work we’re doing sounds exciting!
• you’re a software engineer at heart and you’re comfortable writing software to solve problems
• you’re interested in distributed systems and writing resilient, scalable software
• you have strong experience working on the backend of a technology product
• you’re familiar with some of our Platform technologies, or specialise in just one part
• you want to help build, scale and operate a platform to support a product that you (and everyone you know) use every day
• you’re keen to learn more about new technologies and the arcane inner workings of the financial industry
• you’re comfortable working in a team that deals with ambiguity

Logistics

Salary ranges between £59,000 - £116,000 plus stock options and other benefits.

We can help you relocate to London & we can sponsor visas.

This role can be based in our London office, but we're open to distributed working (as long as you can spend around 20% of your time in London).

We have payroll set up in four countries: the UK, Ireland, France, and Spain. Right now, we can only hire people who work from those countries and we’ll keep this updated with new ones as we expand and are able to hire from more places 🌎

We're usually always hiring for engineers, so there's no closing date for this job.

We offer flexible working hours and trust you to work enough hours to do your job well, at times that suit you and your team.

Diversity and inclusion is a priority for us – if we want to solve problems for people around the world, our team has to represent our customers. So we need to attract the best talent and create an environment that supports and includes them. You can read more about diversity and inclusion on our blog.

If you prefer to work part-time, we'll make this happen whenever we can - whether this is to help you meet other commitments or strike a great work-life balance.

Our interview process is normally a phone interview, a coding task and call to discuss it, and 2-3 hours of onsite interviews that can be conducted via hangouts as well. We promise not to ask you any brain teasers or trick questions. We might design a system together on a whiteboard, the same way we often work together, but we won’t make you write code on one.

Equal Opportunity Statement

At Monzo, embracing diversity in all of its forms and fostering an inclusive environment for all people to do the best work of their lives with us. This is integral to our mission of making money work for everyone.

We're an equal opportunity employer. All applicants will be considered for employment without attention to ethnicity, religion, sexual orientation, gender identity, family or parental status, national origin, veteran, neurodiversity status or disability status.

Job Description

Our true purpose at Castor

Castor is one of the leading platforms for data collection in medical research. We believe standardizing and reusing datasets is key to overcoming the healthcare challenges of the future.

How we operate

Our main Electronic Data Capture (EDC) application runs on a proven stack consisting of Ubuntu, Nginx, PHP and MySQL. For our cloud installations, we orchestrate these setups by using Terraform combined with Ansible for the server configuration management.

Due to the nature of processing medical data, we have clients in different regions across the globe, often with specific regulatory constraints around where and how their research data is stored. To meet these customer demands we combine both traditional as well as cloud-based hosting solutions.

Most of our clients prefer to run in Azure, but we’re using Google Cloud Platform for things like Kubernetes hosting of greenfield projects, blob storage for scalable file upload storage and their Key Management System (KMS) to further secure our data.

For our metrics we’ve begun standardizing on Prometheus and we’re moving towards Loki for log aggregation. We use PagerDuty for alerting, communicate via Slack and host our code on Github.

Why we’re growing our team

With our recent expansion have come new challenges, both in how we organize ourselves and in how we manage and scale our infrastructure in the future.

To further these efforts we have formed a Platform team consisting of SRE and Software Engineering, which we are now looking to grow with the addition of an additional SRE.

Additionally, due to the sensitive nature of medical data, Castor is certified for both ISO/IEC 9001 (quality) and 27001 (Information security). In addition, we have to adhere to a number of other regulations, including Good Clinical Practice (GCP) guidelines.

Our goal is to unite these requirements with emerging SRE practices around infrastructure as code and other principles to create a well designed and documented system, while still allowing us to remain flexible to change.

How you will contribute

Our absolute commitment to patient data security and privacy informs our vendor selection with certified datacenter and cloud providers. To achieve real impact in medical research, Castor needs to operate security around the world.

Historically, our production platform has run on top of managed hosting services. This model doesn’t scale well for our global, international footprint, which is why we are currently expanding our in-house knowledge and transitioning to Infrastructure-as-a-Service providers.

As a Site Reliability Engineer, you’ll have the ability to shape our operations and continuously deliver a working product. Working very closely with the development teams, you’ll collaborate in supporting and structuring our efforts around automation, observability and security. With your help we plan to scale the Castor platform to the next level.

Some things we worked on recently

Whilst there are many operational challenges as we continue to grow and scale at Castor, our Platform team has made great improvements to a variety of our systems already. To give you some examples of what we achieved last month:

• Migrated our DNS to AWS Route53
• Set up automatic documentation pipelines using MkDocs
• Moved our CI/CD pipelines from Jenkins to CircleCI
• Built a key-service on AWS Lambda to store disk encryption keys off-site for an otherwise region-local setup

Your background

You have helped run web-facing services under production workloads and have experienced the challenges that come with maintaining and scaling these systems. Making and owning decisions about systems architecture together with your team is something you enjoy and feel comfortable with.

Qualities we’re looking for include:

• A good grasp on how *NIX systems operate
• The ability to evaluate and implement best practices for IT operations
• A working knowledge of both cloud-native and traditional systems architecture and the trade-offs between them
• Experience with a configuration management framework such as Ansible, Chef, Puppet or SaltStack
• The ability and desire to work with a wide range of open source technologies
• A strong privacy- and security mindset
• Experience with some aspects of Observability and distributed systems: from monitoring, logging and metrics instrumentation to resiliency to failure
• A good understanding of how relational databases operate
• Experience with at least one programming or scripting language, preferably Python or Go(lang)
• Knowledge that a list of skills and requirements doesn’t mean you have to tick every single box to apply ;)

How we say thank you

At Castor we truly live our core values, believing we can achieve anything with a healthy and happy team. With this in mind, we offer the following benefits:

• Our own ‘Castor Burrow’ - brand new offices by Amsterdam Amstelstation
• A competitive salary plus an annual company bonus plan
• Employee Stock Option Programme incentive
• 30 days annual leave plus 6 public holidays
• An individual training and professional development budget
• Flexible working with the opportunity to work from home 1 day per week
• Meditation room with daily yoga, mindfulness and company subscription to Calm
• Lunch and healthy snacks in the office every day
• A new Mac or Dell laptop
