WHAT IT’S LIKE TO WORK HERE
Building greatness in a disruptive era requires strong ambition, talent, curiosity, diversity of thought and a belief that we’re better together.

We are continually on the lookout for talented people from all backgrounds that can further contribute to this amazing culture.
OUR TECHNICAL ENVIRONMENT
Our Engineering Team consists of over sixty five Senior Software Developers that are responsible for the end-to-end ownership of our platform, from architecture through to infrastructure. Individually they are all exceptional at what they do, but by working collaboratively within a team, consistently applying best-practice and automating absolutely everything they are able to build world-class software for our customers.
We don’t mind whereabouts our Developers are based as we are happy for our team to work from anywhere in the UK or EU, with most of them choosing to work remotely most of the time. That being said, we do also have London and Amsterdam offices, so should they ever wish to work from these, they are most welcome.
THE TOOLS WE USE
It’s very much a “best tool for the job” mentality at Form3 and our tech-stack is continually evolving but to give you a flavour of what we’re currently working with here are some of the tools we use;
Languages: Go (and some Java, Python, Ruby)
Tools: Kubernetes, Terraform, Docker, Vault, Consul, Linkerd, AWS: SQS, SNS, EC2, RDS
Methodologies: Agile, Scrum, Kanban, TDD, BDD, Pair-Programming
THE SKILLS WE’RE LOOKING FOR
Whilst experience of the above technologies would be nice, it is by no means essential. We are looking to speak with well-rounded, Senior Software Developers who have a breadth of experience across a variety of programming languages, have an understanding of distributed systems and cloud computing alongside an appreciation of automation and the DevOps culture. Candidates should also value the importance of code quality and software development best-practice, whilst being passionate about technology and enjoy working collaboratively within a team.
Our hiring process varies depending on the role and the candidate, but this should give you an idea of the steps you should expect to follow:

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:
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:
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:
€50k - €70k
As one of the fastest growing Online companies in Europe, we offer a unique opportunity for you:
Our team collaborates on solving some complex development tasks that result from our continually increasing numbers of sellers and buyers (15 million monthly visitors and rising!). We’ve already implemented localisations for various European countries and will be expanding even further, outside of Europe, in the near future. And that is why we need your help!
We want to expand our team by introducing even more expert knowledge. You will work on challenges around scale, microservice architecture and implementing new features in Product focused innovation teams in which Front-End developers, Back-End developers, a Designer, a Data Scientist, and a Product Owner all work closely together. We are driven by A/B-testing and automated testing, which allows us to do multiple releases per day on our high-traffic website.

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.
