Job Description

We are looking for an engineer with a strong platform mindset who can make development more consistent, reliable, and scalable across many product teams and applications. You will help define golden paths, improve shared frontend foundations, strengthen standards such as accessibility and verification, and support product teams through tooling, migrations, governance, and automation. The primary focus is on a broader frontend platform impact and making the codebase easier to change, including with AI-assisted workflows. Important: the position is available only under a standard contract of employment with 80% of tax deductible cost.

Job Responsibility

  • Build and evolve frontend platform foundations that help product teams deliver consistently across many applications
  • Discover recurring needs and friction across product teams, and turn them into reusable patterns, tooling, workflows, and golden paths
  • Define and maintain shared standards, documentation, contribution models, and governance for frontend consistency, accessibility, reliability, and long-term maintainability
  • Drive alignment, adoption, and migrations across teams, helping replace inconsistent local patterns with shared, supported solutions
  • Build AI-assisted automations and agentic workflows that help scale platform improvements, reduce manual effort, and improve consistency across teams

Requirements

  • Senior-level experience, typically 5+ years in software engineering, with a track record of driving cross-team technical work
  • Experience building or evolving frontend platforms, shared engineering foundations, golden paths, or design systems used by multiple teams
  • Experience influencing frontend architecture, standards, or technical decisions beyond a single team
  • Experience improving developer workflows, frontend reliability, or delivery consistency across multiple applications or team
  • Strong hands-on experience building production frontend applications with modern web technologies
  • Experience with Node.js or comparable backend technology, especially in the context of BFFs, frontend-facing APIs, or full-stack platform work
  • Strong collaboration skills and experience working across Engineering, Design, and product teams to drive adoption of shared solutions

Nice to have

  • Experience working across Angular environments
  • Experience with monorepos, microfrontends, or shared frontend tooling
  • Experience improving build, test, CI, or verification loops for frontend teams
  • Experience with inner source or platform engineering ways of working
  • Experience with Web Components, ideally Lit
  • Public speaking, presentation, or facilitation skills that help share standards, explain platform changes, and drive adoption across teams
