What will you do?

You’ll play a critical role in evolving our core web platform — both frontend and backend — with a focus on performance, API design, and product integrations. This is a backend-heavy role with a full-stack flavor.

  • Introduce structured pagination, connection pooling, or background jobs

Database Modeling & Architecture

  • Enhance scalability and maintainability.
  • Debug, refactor, and optimize slow queries.

Integrations & Observability

  • Hook up tools like PostHog, Mixpanel, and Sentry for better product & tech insight
  • Build integrations with external APIs for internal tools or client-facing features

Who We’re Looking For

  • Strong Python developer with experience using SQLAlchemy
  • Frontend experience with Vue.js (or another SPA framework)
  • Comfort with frontend responsiveness, UX, and styling polish
  • Solid CSS skills (flexbox, CSS variables, utility-first frameworks)
  • Deep experience with PostgreSQL and relational design
  • Query performance ninja — can explain indexing, execution plans, JOIN optimisation, and caches
  • Knowledge of security best practices (JWT, SSO, OWASP top 10)
  • Skilled in designing efficient, scalable REST APIs

What Success Looks Like

  • Noticeably faster frontend performance
  • Cleaner, more maintainable APIs and schemas
  • Improved monitoring and external tool integrations
  • Seamless collaboration with other engineers and product folks
  • Tangible impact on platform features and user experience
