We’re a revenue-generating startup with strong product-market fit, and we’re growing fast.

Join us now and you’ll work on impactful features that directly shape our platform and make a real difference to our customers.

What you’ll do

• Design, build, and ship high-quality front-end features using TypeScript and Vue.js.
• Own features end-to-end: translating product requirements and Figma prototypes into intuitive user experiences, building robust components, integrating with APIs, testing, rollout, and iteration.
• Help shape our front-end architecture, ensuring the codebase remains scalable, maintainable, and easy to work with as the product grows.
• Work closely with backend engineers to deliver customer-facing outcomes, not just “tickets”.
• Build thoughtful, accessible, and performant interfaces that work reliably for real users in production.
• Help uphold strong engineering standards through thoughtful code reviews, testing discipline, clean architecture, and pragmatic decision-making.
• Contribute to delivery practices: CI/CD improvements, incremental shipping, automated testing, and maintaining a high-quality codebase.

What we’re looking for

• 5+ years’ experience building and shipping production front-end applications.
• Strong experience with TypeScript and Vue.js, ideally in complex SaaS or B2B product environments.
• Solid understanding of modern front-end architecture: component design, state management, routing, API integration, testing, and performance.
• Experience building maintainable design systems or reusable component libraries.
• Comfortable working closely with APIs, understanding data contracts, edge cases, loading states, error handling, and user flows.
• A strong quality mindset: you care about usability, accessibility, maintainability, security, reliability, and clear documentation.
• Comfortable working in a fast-moving startup environment where ownership, pragmatism, and clear communication matter.

Bonus points for

• Experience with Figma, particularly working from prototypes and collaborating on interaction flows.
• Payments/fintech knowledge (reconciliation, idempotency, auditability, ledger concepts).
• Experience with distributed systems patterns (queues, background jobs, retries, rate limiting).
• Security experience (threat modelling, OWASP-style concerns, secure API design).
• Familiarity with Terraform.

Our stack

• Backend: Python, Flask
• Data: Postgres
• Cloud: AWS
• Edge: Cloudflare
• Infrastructure as Code: Terraform
• Delivery: CI/CD, automated testing, observability tooling

How we work

• Pragmatic, high-ownership teams with a bias to shipping
• Clear communication, strong collaboration, and continuous improvement
• Code reviews and sensible standards that keep quality high without slowing delivery
