Full-Stack Engineer

Why This Full Stack Engineer Delft Role Stands Out

In this position, you’ll work across the full stack using technologies like Next.js, Node.js, Type Script, and Python while contributing to secure, scalable healthcare solutions.

Role Description

If you are looking for a Full Stack Engineer Delft opportunity, this role offers a unique chance to build impactful healthcare software in a hybrid environment. As a Full Stack Engineer in Delft, you will be responsible for both front-end and back-end development tasks, software development, and full-stack development.

  ; understanding versioning, pagination, and error contracts.
• Hands‑on with authentication & authorization (SSO/OIDC/OAuth2), session/JWT handling, and role/permission models (RBAC/ABAC).

Databases

• Experience with both relational (e.g., Postgre
  
  SQL/MySQL) and document/No
  
  SQL databases (e.g., Mongo
  
  DB), including indexing and data modeling trade‑offs.

• Containers (e.g., Docker, Podman).
• CI/CD (e.g.,
  Git Hub Actions
  , Git Lab CI
  ) with automated pipelines.
• Baseline observability skills (logging/metrics, basic dashboards) and performance-minded development.

Soft‑skills

• Ownership & initiative: You identify problems, propose pragmatic solutions, and drive them to completion.

Nice‑to‑Haves

• Working knowledge of at least one compiled language (e.g., Go, C#, C++, Rust, or Java).
• Exposure to LLM agentic systems with their components (e.g.,
  vector
  databases, retrieval/RAG, MCP
  , orchestration frameworks, knowledge graphs).
• Comfort with infrastructure/architecture topics (scalability, resiliency, security).
• Knowledge of Infrastructure-as-Code tools (e.g., Terraform, Open Tofu).
• Experience implementing observability and monitoring (metrics, logs, traces, alerting).
• Interest in self‑hosting and developer tooling; ability to evaluate and operate open‑source systems. Dutch language proficiency.

Why Join Us

• Mission with real‑world impact in healthcare and clinical research.
• Autonomy and high ownership in a fast‑moving, supportive team.
• Access to modern tooling and business subscriptions to leading AI platforms.
• Growth opportunities will arise as we scale, and your work will be visible and meaningful.
