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

Our Vision 🌏🏡

To help people with housing, anywhere.

Our Mission 💻✨

Building a safe, efficient and global rental marketplace for anyone looking for or renting out a place.

Our Core Values 💛

We Care. We Perform. We Evolve.

Your Impact 💥

As we have reached the scaleup phase at HousingAnywhere, our rapid growth has brought on new challenges. We are rethinking the platform architecture to meet imminent growth needs. You will have the opportunities to bring in your ideas in the context of microservices, stream processing, API, security and data integrity.

At platform we are shaping the vision for the future architecture of HousingAnywhere. You will help other teams to build new features on top of our architecture, and make sure that concerns like reliability, security, privacy and performances are met.

We are pragmatic developers, and often we need to think out of the box to solve tricky technical challenges. Technology hypes inspire our work and give us ideas, but we realize that the context in which we build our solutions is what matters most. You will help us consider the challenges we face when adopting new technologies or techniques.

You will help your colleagues and your leaders to solve problems and move faster, as well as they will do with you.

Our mission as the platform team

As a Software Engineer for the Platform Team, you will be joining the team responsible for the backend logic of HousingAnywhere’s marketplace, and for standardizing the way our partners integrate with our platform.

Our team is here to provide HousingAnywhere with a scalable composable architecture that allows the organization to scale the business and teams on top of it.

We achieve our goals by:

• developing the technical vision and standards on the platform that accommodate the needs of the housing rental market for the next 10 years
• developing the standards for the exchange of information between systems in the accommodation rental market.

Let’s work together on the following

• We are currently refactoring the monolith in context boundaries using Domain Driven Design techniques. Our goal is to come to an architecture that will allow us to break the monolith in microservices and break dependencies with the database.
• We are working on bootstrapping our journey to let partners integrate with our platform. We are defining and implementing the architecture that can integrate seamlessly the variegated technologies the industry uses.
• We are rethinking our approach to CI, and simplifying our suites of tests.
• We already extracted frontend as a service from the backend monolith, but the code still leaves in one repository. We want to gain independence by extracting backend code from frontend code and have separate deployment pipelines.
• We are working closely with the operations team to move our services to kubernetes. We are currently sending a small percentage of traffic to the cluster and are facing some performance issues. We are investigating possible next moves to fully work on the cluster.
• We are creating an internal RFC to plan how to move towards an event driven architecture by introducing Kafka. We are researching impacts, costs and value that we get by getting into such a path.

And our stack?

• Go
• Postgres
• Redis
• NSQ
• Docker
• Kubernetes
• Github
• Google Cloud Platform
• GRPC/Protobuf

Who you are

• A product-oriented person: you love developing products that help people and you’re driven by the impact you can make.
• A problem solver: you structure your thoughts and you propose your ideas towards solving a problem or creating an opportunity.
• An advocate of clean,simple and pragmatic solutions. You always have intention, adaptability and scalability in mind.
• A real team player: You respect the work of all your colleagues no matter their seniority level. You also understand that making mistakes is part of the job and that the important thing is to learn from these mistakes. You are always keen to help others, but you are also not afraid of asking for help yourself.
• A great communicator. We don’t expect you to be a master story teller(although we do love stories), but we expect you to communicate your expectations clearly with all your stakeholders.
• A tech junkie! You are interested in new technologies and you constantly seek to improve personally, whether that is at work or in your spare time.

What we offer:

🚀Get ready to make a real impact and hit the ground running with early responsibilities. You have the opportunity to take full ownership of your work and dare to do things differently. Here, all ideas matter.

👩🏻👨🏾👦🏼👽 Work with a crazy unconventional team! Think 90 people from 30 different nationalities. It’s like being on a round-the-world trip while you’re in the office.

📈 Trainings, workshops, conferences, books. It’s up to you.

📚 Budget for Dutch or English classes to help you kick off your stay in the Netherlands, and help you immerse into the Dutch culture.

🌇 Work in the heart of Rotterdam in an office with an amazing view! If you’re looking for a city that is always packed with new things to discover, amazing architecture, a strong international community, this is the perfect place for you!

👕We don’t care about what you wear. You’re welcome to wear a 3-piece tuxedo or even a dragon onesie, we won’t judge you. Maybe a little.

Job Description

Please note: if you’re a recruiter or a development company, don’t waste your time contacting us. We are not interested for sure.

At Careibu we are aiming to build the best social care community by students in the world. We are looking for capable, creative developers who want to help us accomplish that goal.

About Careibu Careibu is all about social care. Through our platform, we connect students to people for help at home. Our students work as babysitters, home cleaners and elderly assistants. Careibu’s Dutch community consists of 32.000+ students and 13.000+ clients. In Juni 2018, we officially launched in the German market (Berlin). Our mission is to bring all generations in society together and provide students a social side job.

Careibu was founded in student accommodation by two sisters, Lotte and Anne. They have grown the business from their student rooms to a team of 13 people which continues to rapidly grow. Our head office is located in Amsterdam.

Things we are working on We’re still a small company with an even smaller development team (CTO, product owner, backend developer and 2 mobile developers). This means you will need to wear many hats in the beginning but it also means there are many interesting challenges ahead that you can specialise in if you like. Broadly we are: – Migrating from legacy platform which has some interesting challenges – Improving and expanding our iOS & Android applications

Our technology stack We still maintain a stack built in Angular 1 (web UI), PHP (backend) and MySQL (data), however we are incrementally migrating to a new technology stack based on a Golang backend with native mobile apps (Swift for iOS and Java for Android).

Since we develop, test, deploy and operate our systems, we do work with other technologies that automate such processes, like GitLab, GitLab-CI, Docker and AWS’s ECS & RDS.

You should apply if – You want to be involved in building a product that has a social impact – You’ve worked in GoLang or you are a senior backend dev willing and able to learn quickly – You don’t mind exploring our legacy PHP system & rebuilding functionality on our new platform – You like to also be involved in improving the devops aspects of our stack – Experience with any of AWS EC2 & ECS, Docker or JavaScript/NodeJS is a big plus – You have a proactive attitude and are not afraid of failing – You (want to) live in the Netherlands (remote is not possible) – You have a EU passport (we don’t provide visa’s)

You want to apply or you have any questions? Email Anne (anne[at]careibu.com).
