Job description

At Sytac, we build high-performing engineering teams for leading organizations. We combine a pragmatic, people-first culture with technical craftsmanship giving engineers autonomy in real production environments.

For one of our major enterprise clients, we are looking for a Senior Full-Stack Engineer. You will join a high-impact team focused on building scalable design systems and high-performance applications using a domain-driven, monorepo approach.

What you’ll do

  • Develop frontends: Build modular components using TypeScript and Angular.
  • Build backends: Create Node.js services with an API-first architecture.
  • Manage monorepos: Use Nx for scalable dependency and code management.
  • Ensure accessibility: Architect UIs that comply with WCAG and ARIA standards.
  • Automate testing: Integrate Jest and Cypress/Playwright into CI/CD pipelines.
  • Optimize performance: Tune lazy loading, bundles, and change detection.
  • Orchestrate infrastructure: Deploy via Docker and Kubernetes using GitHub Actions.
  • Monitor health: Use Grafana for platform observability and performance tracking.

What we’re looking for

  • Senior-level experience in full-stack software engineering.
  • Frontend Expert: Mastery of Angular, TypeScript, and component architecture.
  • Node.js Proficient: Strong background in TypeScript-based backend development.
  • Engineering Rigor: Deep knowledge of design patterns (Factory, Observer, Strategy).
  • DevOps Savvy: Hands-on experience with Docker, K8s, and automated builds.
  • Quality Focused: Disciplined with linting, formatting, and test automation.
  • Fluent English + NL residency (no sponsorship).

Tooling: Angular, Node.js, TypeScript, Nx, Docker, Kubernetes, GitHub Actions, Jest, Grafana.

 

Nice to have

  • Framework versatility: Experience with React or Stencil/Lit.
  • Server-side expertise: Knowledge of SSR and performance-focused optimization
