Job Description
Brief is the context navigator for product teams. We aggregate business context (decisions, customer research, work pipeline, team knowledge) and make it legible to both people and AI agents through chat, Slack, CLI, and voice.
We believe the boundaries between product, design, and engineering are dissolving. The scarce resource is no longer engineering hours; it's taste, judgment, and the conviction to ship. So we hire Product Builders who wear all three hats and own whole things.
This is the engineering-focused shape of that role. Our bet: the disciplines blend, but the best builders still have a center of gravity. Yours is engineering, a long tenure writing real software, paired with genuine taste and discernment for UX, UI, and user empathy.
If you've spent the last year thinking hard about how AI changes the product-building loop, using Claude/Cursor/Copilot not as autocomplete but as a genuine collaborator, you might be exactly right for this.
About The Role
- Define, design, and build features yourself, start to finish. No spec, no handoff.
- - Build customer-facing UI that's fast, opinionated, and polished.
- - Work directly with the founders on product direction. No PM layer, no design queue.
- - Use AI agents in your daily workflow, and build products that AI agents use themselves.
- - Find what's broken, confusing, or missing and fix it before being asked.
- - Drive architecture decisions, not just implementation.
About You (Must Have)
- A long tenure as a software engineer. Roughly 6+ years.
- - Strong TypeScript and React fundamentals, comfortable across the full stack.
- - Product taste is non-negotiable.
- - Naturally curious and detail-oriented.
- - High ownership.
- - Has worked at a startup or somewhere with a genuinely high engineering bar.
Strongly Preferred
- Built conversational UIs or chat interfaces with complex state
- - Experience with LLM APIs (Anthropic/OpenAI) and prompt engineering
- - Understanding of product management workflows
