In-person and Remote Working Balance

We work in a flexible hybrid model. Most squads collaborate in person around two days per week, with flexibility around which days work best. This helps us balance meaningful face-to-face collaboration with time for focused engineering work.

What You\'ll Be Doing

As a Senior Frontend Engineer On Compass, You Will

  • Lead high-impact technical initiatives: Own the design and delivery of complex frontend features, from conversational UI patterns to insights visualisation
  • Shape products from discovery to delivery: Partner closely with Product and Design during discovery, translating evolving requirements into pragmatic technical solutions that solve real user problems
  • Build the Conversational AI and Insights experience: Create robust, scalable frontend systems using VueJS and TypeScript that handle streaming responses, dynamic visualisations, and complex state management
  • Integrate seamlessly: Use OpenAPI contracts to build reliable integrations with our conversational AI, survey-building, and insights services - handling real-time data streams and failure states robustly
  • Balance speed with sustainability: Ship quickly while maintaining high code quality, performance, and testability. Proactively reduce technical debt and improve system health
  • Elevate the entire team: Provide thoughtful code reviews, mentor other frontend engineers through pairing, and contribute to shared patterns and standards across the Frontend Chapter
  • Drive measurable outcomes: Focus on user outcomes, not just output, using data to inform iteration and improvement

You’ll have autonomy in technical decisions, support for growth, and the opportunity to influence how users interact with AI-powered survey creation and insights.
