Software Engineer (Backend)

AT CASTOR, WE DRIVE FASTER, SMARTER MEDICAL RESEARCH

We believe that faster, more diverse clinical trials help extend the human health span and provide a greater return on investment.

We strive to improve the clinical trial experience for patients, sites and sponsors, using technology to accelerate every step of the clinical trial journey.

Our modular clinical trial platform enables the capture and re-use of research data from anywhere, anytime and helps optimize each activity in the clinical trial journey by reducing human effort with technology. From recruitment to monitoring, we help make it easier to design and deploy trials, enroll and engage patients, collect data and analyze results.

Next to being very purpose-driven, we are proud of our caring company culture. We follow our values diligently and take the well-being of each Castorian seriously. Sounds like something for you? Read on !

WHAT YOU`LL FOCUS ON

As a Software Engineer (Backend), you’ll be joining our new identity team. Here you’ll work on features and (internal) APIs to support authentication, user management, digital signatures and access control checks. We aim to provide our customers with one central account to access all Castor applications, as well as one centralized access control system.

Concurrently, you will support other product teams to replace their (legacy) identity and access control functionality with the applications, APIs and libraries we develop.

You will be responsible for:

• Designing, debugging and coding for a growing network of medical researchers
• Analyzing performance data and optimizing bottlenecks
• Deconstructing user requirements to model optimal, scalable, solutions
• Working on automated toolchains to construct and integrate our applications

WHAT YOU`LL BRING

You’ll definitely have:

• Practical experience with PHP, design patterns, OOP, and automated tests
• Some exposure to modern Java development
• Experience in building web-based applications (SaaS)
• Knowledge of web security, common vulnerabilities and their mitigations
• A creative mindset with the ability to help solve challenging domain problems

It would be good if you had:

• Experience within life sciences, healthtech or e-clinical products.
• Experience with authentication standards like OAuth 2, OIDC and/or SAML and authentication systems like Keycloak, Auth0 and/or Okta
• Experience with Kubernetes
• Experience with decentralized access control systems

Please note that we are open to hire from different European countries and also authorized to provide visa sponsorship for the Netherlands. However, we are unable to accept applications from France, Spain, Bulgaria, Sweden, and Switzerland.
