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:
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:
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:

WHO WE ARE
After the 2008 financial crash, the international financial and business environment is more regulated than ever. The amount of required paperwork has increased exponentially. The deals are being blocked, the accounts are being frozen, the business is often getting paralyzed.
Project Plato was born in 2015 as an autonomous R&D unit working for Dolfin, an established British investment company, with the aim of automating sensitive business operations. We are a young and ambitious team frustrated by inefficiency of existing solutions.
5 years later, with the help of our software solutions, Dolfin was able to have
But this is only the beginning. Our mission is to help companies and business professionals around the world communicate with each other and do business with trust and simplified paperwork.
OUR TECH STACK
As a serious, business-oriented company, we develop our solutions exclusively in COBOL.
Just kidding! We use modern and diverse IT infrastructure. Our solutions are web-based, with backends in Golang andPython and frontends in Typescript and React. Data storages include PostgreSQL, DynamoDB and Amazon S3. The infrastructure consists of multiple backend services managed via Kubernetes/Helm, integrated with various AWS and third-party services. We also use Google Bazel, a secure and robust build system.
We strive to make our development process predictable, change-proof and well-organized to achieve the fastest possible product delivery pace without compromising reliability.
OUR TEAM
We are still small: Project Plato is less than 15 people in total but we are planning to grow to 20 soon. As part of the Project Plato back-end team, you will be working closely with Oleg and another 3 senior engineers. Oleg is our lead backend engineer who has been part of the team since 2015 when we established our office in Amsterdam. We are a group that values trust, growth, agility, mutual respect, taking ownership, and learning from each other through a culture of open feedback.

From adventure travel and backpacking to honeymoons and family vacations, we deeply care so that every traveller can make the best-informed accommodation choice at the absolute best conditions for every trip.
We are looking for an enthusiastic and motivated Back-End Engineer to help build the most scalable and flexible APIs in the industry. You will be joining FindHotel’s Marketplace Platform Tribe. You will be working with other squads across tribes and closely interact and actively collaborate with the Software Engineers, Data Analysts, Data Scientist, and PO in the team.
We are working with a modern stack consisting of Go, Redis, AWS (ElastiCache, ECS, S3, Batch), Snowflake, and more. We process thousands of requests per second and integrate with many suppliers and other partners. The products developed by the Offers team are a core part of FindHotel’s platform allowing us to offer the best possible comparison and offers to every traveller, worldwide. Hence, anything that you will develop and ship on production will have an immediate effect on our users and on our business performance. We work in a flexible, results-oriented and customer-centric team structure, focussed on shipping value in a collaborative fashion, with hopefully just the right amount of bureaucracy.
Work in a team to solve challenging problems, and design and develop products that will help to bring to our travellers the best deals available in the market. Identify bottlenecks and opportunities for improvements in terms of performance, reliability, and code quality. Integrate and improve (new) provider integrations. Help to maintain and improve our infrastructure and scale it to support our continuous growth in a cost-effective way.
In the morning, you and your fellow engineers have a refinement session with the PO to discuss the upcoming features on the roadmap. You carefully consider the impact of the new feature on the entire product and raise questions and make suggestions of what is the most pragmatic approach to balance the technical excellence with the time to market. You are part of a discussion that builds on top of each other suggestions, ideas and comments. Today you have chosen to come to the office and after lunch you play table tennis or pool or go for a walk with colleagues in the city centre. In the afternoon, you enter a deep work period and finish working on improving a core component in the rates and availability API. Once down with that work you jump on a zoom call with the rest of the team to discuss the challenges and next steps with the PoC the team is building in this sprint. Throughout the day you monitor the product operations using DataDog.
