About the role
About
the Role We are building the control plane for AI agents in teams and companies. As a UI Engineer, you'll help build the user-facing layer of that control plane - the web applications, workflows, and interfaces that make powerful agent infrastructure usable by real teams. You'll work alongside another senior UI engineer, with real ownership over specific surfaces and problems rather than sole responsibility for the whole frontend. Your core craft is React and TypeScript: component architecture, state management, performance, and the judgment to turn complex systems into interfaces people trust. Our designers aren't just handing off mockups - several of them now build UI directly, using coding agents to write real production code. A big part of this role is partnering with them: helping them realize their design intent, reviewing and hardening what they ship, and bringing software engineering discipline — architecture, performance, testing, maintainability - to the frontend as it grows. You won't own visual design; that's their job. You'll help ensure the engineering quality of what ends up in production. You'll also work with our Python backend - reading and extending services, shaping APIs, and making sure the frontend and backend evolve together. You'll also help define a new interface paradigm: agents as an interactive modality - not just chat, but structured, controllable, and production-grade workflows. If you love deep frontend craft, enjoy raising the bar on code quality without gatekeeping who gets to write it, want full-stack range without carrying backend architecture solo, and care about how humans interact with autonomous systems - we want to talk.
What You'll Own Web Application & Product Experience (primary focus) Help shape the architecture and implementation of our React + TypeScript web application, alongside our other senior UI engineer Build high-performance, stateful interfaces for managing agents Develop dashboards, policy configuration UIs, audit views, and workflow builders Establish frontend patterns, component structure, and state management conventions the whole team - including designers - can build on Own specific surfaces end-to-end, from first pass to production Backend & API Work Extend and maintain Python backend services that support the UI Design or shape APIs for agent control, policy configuration, and observability Work within a Kubernetes-native, cloud-based distributed system Collaborate on schema design and data modeling where it affects the frontend experience Agent-Native Interfaces Explore agents as a new user interface modality Design structured, interactive agent workflows beyond simple chat Combine UI controls with agent reasoning Experiment with hybrid patterns: visual + conversational + automated systems CLI & Future Interfaces Contribute to a TypeScript- or Python-based CLI Design consistent interaction patterns across web and CLI Lay groundwork for potential future mobile interfaces Design Engineering & Collaboration Partner directly with designers as they build UI using coding agents — pairing, reviewing, and unblocking them Review and refactor designer-written code to meet engineering standards for architecture, performance, and maintainability Help designers translate design intent into robust, production-ready code rather than one-off prototypes Know when to harden code for production and when a good-enough prototype is the right call Work closely with product and design to translate concepts into shipped software, and iterate quickly based on feedback
