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.
