BJAK is building AI-powered automation systems that simplify complex insurance workflows - from quotations and policy issuance to claims and customer support. To make this possible, we're looking for an experienced Frontend Engineer based in the United Kingdom to help build fast, intuitive, and reliable customer journeys across our checkout, payments, and policy renewal platform. This is a fully remote role where you'll collaborate with product managers, designers and engineers across our global team to deliver high-quality experiences that directly impact customer satisfaction, conversion and business growth.

Your Mission

Design and build exceptional frontend experiences that make purchasing and renewing insurance effortless. You'll develop modern web applications that power our checkout, payment and policy renewal platform, ensuring every customer journey is fast, reliable and frictionless.

What You'll Do

  • Build modern web applications using React, Next.js, TypeScript and other modern frontend technologies.
  • Develop customer-facing checkout, payment and policy renewal experiences.
  • Translate product and UX designs into polished, responsive interfaces.
  • Integrate frontend applications with backend APIs, payment providers and policy management services.
  • Optimise application performance, responsiveness and conversion across desktop and mobile.
  • Build and maintain complex transactional workflows, including pricing, validation, payment and confirmation.
  • Contribute to frontend architecture, reusable component libraries and engineering best practices.
  • Collaborate closely with product managers, designers, backend engineers and QA throughout the development lifecycle.
  • Continuously improve code quality, performance and user experience.

What We're Looking For

  • Bachelor's degree in Computer Science, Software Engineering or a related discipline, or equivalent industry experience.
  • Proven experience building production-grade web applications.
  • Strong proficiency in JavaScript and TypeScript.
  • Commercial experience with React and modern frontend frameworks such as Next.js.
  • Strong understanding of HTML5, CSS3 and responsive web development.
  • Experience integrating frontend applications with RESTful APIs and backend services.
  • Solid understanding of component-based architecture and scalable frontend design.
  • Experience improving frontend performance and debugging production applications.
  • Familiarity with Git, CI/CD pipelines and modern software development practices.
  • Strong analytical and problem-solving skills with excellent attention to detail.
  • Excellent communication skills and experience working within distributed engineering teams.
  • Comfortable thriving in a fast-moving, product-led environment.

Nice to Have

  • Experience building checkout platforms, payment products or subscription and renewal journeys.
  • Experience with Stripe, Adyen or other payment providers.
  • Experience running A/B tests or working on conversion optimisation initiatives.
  • Experience with Next.js, Vite or modern frontend tooling.
  • Familiarity with Node.js or Python.
  • Experience with Playwright, Cypress, Jest or Vitest.
  • Understanding of authentication, authorisation and web security best practices.
  • Experience with Redux, Zustand or similar state management libraries.
  • Contributions to open-source projects or active participation in developer communities.
  • Experience building high-traffic consumer web applications.

The Kind of Engineer We're Looking For

  • Thinks beyond UI and understands the entire customer journey.
  • Obsesses over usability, performance and reducing customer friction.
  • Anticipates edge cases and builds resilient transactional experiences.
  • Writes clean, maintainable and scalable code.
  • Takes ownership from implementation through production.
  • Balances engineering quality with speed of execution.
  • Enjoys solving product problems that directly influence customer conversion and retention.
  • Excited by building AI-powered products that deliver measurable business impact.

This Role Isn't Right If You

  • Focus primarily on visuals without considering the underlying customer journey.
  • Prefer implementing predefined specifications over solving product problems.
  • Overlook edge cases, performance or production reliability.
  • Produce code that's difficult to maintain or scale.
  • Prefer highly structured environments over fast-paced product development.

Success in This Role

  • Deliver fast, intuitive and reliable checkout experiences.
  • Improve customer conversion across purchase and renewal journeys.
  • Build scalable frontend architecture that supports continued product growth.
  • Reduce friction and drop-offs throughout multi-step transactional flows.
  • Become a trusted engineering partner across product, design, backend engineering and operations.
