Engineer - Product & User Interface Systems

We're building the control plane for AI agents in teams and companies.As a Founding Engineer focused on Product & User Interface Systems, you will design and build the user-facing layer of that control plane - the web applications, workflows, and interfaces that make powerful agent infrastructure usable by real teams.This is not a "frontend-only" role. You will work across the stack: distributed cloud-based systems, Kubernetes-based services, and modern web applications. You'll collaborate deeply with product and design to turn complex infrastructure into intuitive, high-leverage user experiences.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 care about product quality, system coherence, and shaping how humans interact with autonomous systems - we want to talk.What You'll OwnYou will build and evolve the user-facing layer of our platform:Web Application & Product ExperienceDesign and implement React + TypeScript web applicationsBuild high-performance, stateful interfaces for managing agentsDevelop dashboards, policy configuration UIs, audit views, and workflow buildersCreate systems that make complex agent behavior understandable and controllableFull-Stack EngineeringBuild backend services supporting the UIDesign APIs for agent control, policy configuration, and observabilityWork within a Kubernetes-native, cloud-based distributed systemCollaborate on schema design, data modeling, and service boundariesAgent-Native InterfacesExplore agents as a new user interface modalityDesign structured, interactive agent workflows beyond simple chatCombine UI controls with agent reasoningExperiment with hybrid patterns: visual + conversational + automated systemsCLI & Future InterfacesContribute to a TypeScript- or Python-based CLIDesign consistent interaction patterns across web and CLILay groundwork for potential future mobile interfacesProduct & Design CollaborationWork closely with product and design to translate concepts into shipped softwareParticipate in usability thinking and iterative refinementShip quickly, iterate based on feedback, and improve continuouslyWhat We're Looking ForExperience building production-grade web applications in React + TypeScriptComfort working across the full-stack of distributed systemsStrong API design instinctsExperience shipping SaaS products used by technical teamsAbility to translate complex backend systems into usable interfacesStrong product intuition and UX sensibilityBonusExperience building developer tools or control-plane softwareExperience designing workflow builders or configuration-heavy interfacesExperience with real-time systems or streaming UIsExperience building CLIsFamiliarity with LLM-powered products or agent systemsWhat Makes This Role UniqueYou'll help define how teams interact with autonomous agents.You'll build interfaces for infrastructure-level systems.You'll operate at the intersection of product design, distributed systems, and AI.You'll have ownership from concept to production.This is a high-impact, high-autonomy role. You'll influence product direction and user experience at the foundational stage of the company.Who Thrives HereEngineers who care about product polish and system clarity.Builders who like working across frontend and backend.People comfortable turning complexity into usable abstractions.Those excited about inventing new human-AI interaction models.
