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 Own
You will build and evolve the user-facing layer of our platform:
Web Application & Product Experience
Design and implement React + TypeScript web applications
Build high-performance, stateful interfaces for managing agents
Develop dashboards, policy configuration UIs, audit views, and workflow builders
Create systems that make complex agent behavior understandable and controllable
Full-Stack Engineering
Build backend services supporting the UI
Design APIs for agent control, policy configuration, and observability
Work within a Kubernetes-native, cloud-based distributed system
Collaborate on schema design, data modeling, and service boundaries
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
Product & Design Collaboration
Work closely with product and design to translate concepts into shipped software
Participate in usability thinking and iterative refinement
Ship quickly, iterate based on feedback, and improve continuously
What We’re Looking For
Experience building production-grade web applications in React + TypeScript
Comfort working across the full-stack of distributed systems
Strong API design instincts
Experience shipping SaaS products used by technical teams
Ability to translate complex backend systems into usable interfaces
Strong product intuition and UX sensibility
Bonus
Experience building developer tools or control-plane software
Experience designing workflow builders or configuration-heavy interfaces
Experience with real-time systems or streaming UIs
Experience building CLIs
Familiarity with LLM-powered products or agent systems
What Makes This Role Unique
You’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 Here
Engineers 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.
