The Opportunity

We're looking for a Frontend / Fullstack Engineer who loves building high‐quality user experiences and isn't afraid to own features end‐to‐end. You'll play a key role in shaping the interfaces, workflows, and interactions that make our platform intuitive and powerful for our clients. Your work will span from translating product ideas and design concepts into polished interfaces, to wiring frontend components with backend APIs, to improving performance, accessibility, and reliability. You'll collaborate closely with product managers, designers, and AI engineers to bring features to life—always with a focus on delivering value and making complex things feel simple for users.

This role is ideal for someone who enjoys switching between frontend craftsmanship and practical fullstack work, thrives in a collaborative environment, and thinks about product outcomes just as much as technical solutions.

What We're Looking For

  • Strong Frontend foundations: JavaScript/TypeScript, React, modern component patterns, state management, performance, and accessibility.
  • Ability to turn concepts or Figma designs into polished, production‐ready interfaces.
  • Product‐oriented mindset: focus on user problems and value delivery rather than just completing tickets.
  • Solid Fullstack fundamentals: comfortable working with Node.js or Python, building APIs, and debugging across the stack.
  • Good understanding of testing practices and quality‐driven engineering.
  • Familiarity with modern cloud environments, CI/CD workflows, and deployment pipelines.

Nice to Have

  • Experience building data‐rich UIs, dashboards, or complex workflows.
  • Familiarity with AI‐driven interaction patterns or agent‐based UX.
  • A good sense for UI/UX design quality.
  • Experience with monorepos, modular architectures, or Next.js app router.
  • Exposure to our tech stack or similar tools.

What You'll Do

  • Build intuitive, performant, and scalable user interfaces for both clients and internal users.
  • Work closely with product managers and designers to define, prototype, and iterate on features.
  • Ship fullstack functionality when needed, from UI to API integrations.
  • Contribute to our design system, shared components, and frontend architecture improvements.
  • Integrate frontend interfaces with AI agents, workflows, and real‐time experiences.
  • Apply engineering best practices for performance, testing, and maintainability.
  • Participate in design reviews, code reviews, and team knowledge sharing.
  • Iterate after deployment based on real‐world usage and metrics.
