About this role
Role Overview
- Propose and own technical architecture decisions, balancing pragmatism with long-term scalability
- Develop GraphQL and REST APIs and responsive front-ends using Node.js and React
- Build reusable, best-practice components and shared libraries
- Contribute to our multi-brand design system (Storybook) and Next.js-based web front-ends
- Help scale our SaaS shared services platform (identity, billing, licensing, and more)
- Own application performance and stability — monitoring error rates, reviewing system metrics, and leading the response to incidents
- Lead the team's adoption of agentic engineering practices — using AI coding tools (e.g. Claude Code) not just for productivity, but to rethink how we approach complex, multi-step engineering tasks
- Share learnings across the team and help establish best practices as this space evolves rapidly
- Mentor junior and mid-level engineers through code reviews, pair programming, and 1:1 guidance
- Foster a psychologically safe team environment where engineers can raise concerns, ask questions, and grow
- Act as a constructive mediator when technical disagreements or interpersonal friction arise
- Collaborate closely with product managers and other team leads to align on vision and priorities
- Support and collaborate with the Siemens team on integration projects
Requirements
- 10+ years of experience with at least 5+ years in production web applications (full stack) and 3 years in a mentorship/leadership role
- Strong Node.js skills and familiarity with the broader JS/TS ecosystem (npm, yarn, bundlers)
- Experience architecting and building REST and/or GraphQL APIs
- Advanced HTML, CSS, and JavaScript; strong TypeScript
- Hands-on experience with React and component-based architecture
- Familiarity with React frameworks such as Next.js or Gatsby
- Comfortable with relational and non-relational databases (e.g. PostgreSQL, MySQL, MongoDB)
- Knowledge of modern deployment practices: Docker, Kubernetes, CI/CD pipelines
- Security-conscious: you think about auth, data protection, and attack surfaces as part of normal development
- Experience with application performance monitoring and observability tools (e.g. Sentry for error tracking, Grafana for logs and system metrics)
- Hands-on experience using AI-assisted or agentic coding tools (e.g. Claude Code, Cursor, GitHub Copilot Workspace, or similar)
- Ideally, experience going beyond autocomplete — using agents for code generation, refactoring, test writing, or multi-step task automation
- A natural mentor: you get genuine satisfaction from seeing junior engineers level up
- A good listener: you make space for other perspectives before forming conclusions
- Calm under pressure and skilled at navigating disagreements — between people or between competing technical approaches
- Strong written and spoken English: you can explain complex technical ideas to both engineers and non-engineers
- Experience with security and data protection standards (e.g. ISO 27001, SOC 2, GDPR)
- Prior experience with high-traffic, high-availability applications.
