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 flavour.

  Backend Scalability & API Performance

  • Refactor REST APIs to reduce over-fetching and inefficient database calls.

  • Push async processing across high-latency parts of the stack.

  • Introduce structured pagination, connection pooling, or background jobs

    Database Modelling & Architecture

  • Enhance scalability and maintainability.

  • Debug, refactor, and optimise 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

You’re probably a great fit if you:

• >5y of experience in a professional software team.

• Strong Python developer with experience using SQLAlchemy

• Frontend experience with Vue.js (or another SPA framework)

• Comfortable 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

• Actively contributed to a product-centric team.

• Have strong object-oriented programming skills.

• Proactively solve problems and confront challenges.

• Value teamwork, collaboration, and collective achievements.

• Interest in Large Language Models.

• Fundamental understanding of Machine Learning.
