At Sytac, we build high-performing engineering teams for leading organizations. We combine a pragmatic, software craftsmanship culture with deep technical expertise—giving senior engineers the autonomy to build "paved road" platforms and shared capabilities that empower multiple product teams.

For our client ** within the financial sector, we are looking for an experienced Senior Frontend Engineer ** to join the OneWeb Foundation team. This central engineering team focuses on shared frontend foundations, libraries, and developer experience.

  • Actively incorporate AI tools (e.g., GitHub Copilot) into daily workflows for coding, refactoring, and analysis, while promoting these practices across the organization.
  • Expand and improve regression test automation at scale using Playwright ** , defining best practices for stability and coverage.
  • Strengthen CI/CD pipelines and quality gates while resolving recurring frontend quality issues that impact multiple teams.
  • Act as a technical point of contact, supporting teams with adoption, upgrades, and migrations of frontend solutions.

What we’re looking for

  • 5+ years of software development experience with a heavy focus on frontend engineering and shared libraries/platforms.
  • Strong knowledge of HTML, CSS, and JavaScript ** , alongside modern frameworks like Lit, React, Vue, or Angular ** .
  • 3+ years of experience with Azure DevOps ** , complex Git workflows, and CI/CD pipelines.
  • Practical experience using AI development tools and a solid understanding of web accessibility and performance.
  • Comfortable working in Scrum or Kanban environments with a collaborative, no-nonsense mentality.
  • No sponsorship is available, and candidates must already reside in the Netherlands.
