The Opportunity

In this role, you’ll design and build the interface that lets companies control how AI understands their world – turning fragmented company data into meaningful context for every AI process.

You’ll own the core product experience of Qontext: from designing access controls that define what AI agents can “know,” to building intuitive human-in-the-loop tools for validating and refining context.

Qontext is already getting used by 10+ design partners and we are aiming to launch v1 of our platform in Q2 2026.

If you enjoy deep technical challenges, working from first principles, and shipping products that define a new category – this role is for you.

What You’ll Do

• Design and implement the interface that connects users, data, and AI context

• Develop access control systems defining which AI processes can access specific context

• Build human-in-the-loop (HITL) features for context validation, feedback, and identity resolution

• Turn complex backend logic into intuitive UI, APIs, and workflows that feel effortless

• Integrate with external SaaS tools (e.g., Notion, HubSpot) to extract structured meaning – not just data transfer

You’ll Thrive Here If You…

• Love building beautiful, high-performance interfaces that make complexity usable

• Are fluent in TypeScript, React, and Tailwind, and care deeply about design details and interaction quality

• Think in systems and flows, not just screens – you understand how frontend and backend connect

• Thrive at the intersection of engineering and product design, shaping UX through code

• Value craft, curiosity, and speed – you like to ship, test, and refine fast
