Senior Full Stack Engineer, Frontend Focused

Role Description

We’re building the platform that allows users to design how AI agents and processes actually work. Think of canvas, visualisations, dynamic boxes, live connections, an interface that changes in real time as agents run. It's one of the most complex surfaces we've ever built, and we are hiring for a highly experienced Senior Engineer to own this end-end, working within our AI Workforce Function.

Role Responsibilities

• Design and own the interface for building agent workflows, with real time UI that updates live via WebSockets and server sent events.
• Build the dynamic, state driven interface layer that reflects what's actually happening, not a static form, and make the architecture calls that keep it scaling as complexity grows.
• Work closely with product and design to turn complex, ambiguous workflows into something people actually enjoy using.
• Build reusable components, keep design patterns consistent, and connect the frontend to backend services and APIs (including the orchestration layer), jumping into backend work when it helps ship faster.
• Keep code quality high through testing and review, and make the canvas fast: load times and responsiveness matter here more than almost anywhere else.
• Ship through CI/CD with confidence, debug production issues, and document the architecture clearly enough that others can build on it.

Qualifications

• Strong experience building modern, complex web apps, with a clear frontend lean.
• Deep React and TypeScript experience.
• Real time experience: WebSockets, server sent events, or both.
• Canvas or node based UI experience (think Figma, Miro, or workflow builder style interfaces).
• Strong grasp of modern frontend architecture and component based development.
• Comfortable working with RESTful APIs and connecting frontend to backend.
• Solid HTML, CSS, and modern frontend framework fundamentals.
• Experience with state management for genuinely complex, dynamic UI.
• A track record of owning architecture and technical calls at a senior or staff level.
• Sharp debugging instincts.
• Strong communicator, written and verbal.

Preferred Experience

• Experience building highly interactive, data heavy interfaces.
• Experience with component libraries or design systems.
• Server side rendering or serious frontend performance work.
• Comfortable with cloud hosted, distributed systems.
• Experience shipping large scale, global B2B or B2C products.
• Time spent in a fast scaling product and engineering org.
