Elevate your career with us, where development and progress are at the heart of everything we do.

Your Tasks:

  • Design and develop features across the full stack of the Vulnerability Management Platform, from React-based user interfaces to Python FastAPI backend services
  • Build and maintain RESTful APIs and backend logic to support vulnerability ingestion, processing, and exposure workflows
  • Collaborate with the Data and Security Engineering teams to implement scalable, production-grade features
  • Drive architecture design decisions and contribute actively to technical roadmap discussions
  • Ensure code quality through testing, code review, and mentoring of junior engineers
  • Own QA processes including design and implementation of automated test suites across unit, integration, and end-to-end layers
  • Work in an Agile environment with cross-functional teams across Germany and Spain

 

Your Profile:

  • 5+ years of experience in Full Stack Software Development
  • Strong proficiency in React (frontend) and Python with FastAPI (backend) — both are must-haves
  • Proven experience in QA and test automation — unit, integration, and E2E testing are expected, not optional
  • Proven experience designing, deploying, and maintaining infrastructure on at least one major cloud provider (AWS, Azure, or GCP)
  • Solid hands-on experience with containerization and orchestration (Docker, Kubernetes) in production environments
  • Experience designing and consuming RESTful APIs at scale
  • Proficiency with relational (SQL) and non-relational databases (MongoDB, Redis)
  • Demonstrated ability to make independent technical decisions and lead initiatives end-to-end
  • Strong English communication skills and ability to work in a collaborative, international environment
  • Experience working in Agile environments

 

Nice to Have:

  • Cybersecurity knowledge or experience — particularly in Vulnerability Management or Exposure Analysis
  • Experience with Neo4j or other graph databases
  • Experience with message brokers such as RabbitMQ or similar (Kafka, Redis Streams)
  • Hands-on experience with CI/CD pipelines — strong GitLab CI affinity is a significant plus
  • Familiarity with monitoring tools like Grafana or Azure Monitoring
  • Contribution to open-source projects and a passion for continuous learning
