Site Reliability Engineer Castor EDC Amsterdam, The Netherlands €60,000 to €80,000 a year
February 2020
2 Applicants This Week
More Than 6 Months Old
This job posting is no longer available
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
We are a marketplace for refurbished electronics. These are phones, laptops and tablets that are completely renewed, look like new and function like new. The products combine low price and sustainability. We want to contribute to a more sustainable future.
Small, highly skilled and fun remote dev team
We are currently 6 engineers that all work together remotely. We have in person meetings in the headquarter in Vienna regularly to meet each other and the rest of the company. Balancing fun and efficiency is a high priority.
There is also room in the office for the engineering team. So you can also work from the office in Vienna.
The main focus of the company is to build a fast marketplace platform that can support multiple countries and thousands of transactions. Hence, the engineering team is one of the most important ones in the company.
Collaboration across teams works really well. Although we are working remotely, we are still a strong part of the whole company.
Your Role:
Development of our main API
Development of our smaller backend services
Integration of external systems into our platform
Your Profile:
Formal education in computer science
Significant experience designing and implementing backend services
Significant experience with software development in Go
Good knowledge of SQL and relational database design
You work independently and goal oriented
You have excellent English skills
Additional factors we appreciate:
You have experience with PostgreSQL
You are comfortable working with Linux/*BSD
You have experience working with backend services like Nginx or RabbitMQ
