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 controllableFull-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 boundariesAgent-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 systemsCLI & Future Interfaces

Contribute to a TypeScript- or Python-based CLI

Design consistent interaction patterns across web and CLI

Lay groundwork for potential future mobile interfacesProduct & 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 continuouslyWhat 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 sensibilityBonus

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 systemsWhat 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.
