Founding Frontend EngineerCiridae

This is a product-minded frontend engineer with elite craft and the judgment to turn messy technical requirements into interfaces that make complex systems feel simple and intuitive. A platform discussion, a half-formed workflow, or a rough feature idea becomes a polished product surface that makes the whole team faster. You take a loosely defined need, identify the right workflow, prototype it, make the design calls, and carry it through to production independently.

What you own. The frontend layer of our proprietary platform, Crucible: the interfaces, workflows, templates, and architecture that turn powerful AI systems into usable software. You are shaping interaction patterns, tightening performance, and making complex agent workflows feel clear, fast, and trustworthy. You build in Crucible, creating reusable components and product patterns that FDEs can pull into customer projects again and again. You own net-new building blocks and their maintenance over time, not just one-off UI implementation. Your job is to make the platform excellent enough that everyone else can build on it.

What you bring. Production frontend shipped with taste: React, TypeScript, modern web architecture, and a high bar for UX quality. You have built products where usability, speed, and visual polish mattered. You can navigate ambiguity, make sound tradeoffs without a fully defined spec, and explain those tradeoffs clearly. You are not a designer by title, but you have strong design instincts. You know when a flow is confusing, when a UI is not good enough, and when a reusable component will save the team weeks later. You are opinionated about what great looks like, but can collaborate with the FDEs and delivery teams closest to the customer and system constraints. You are self-sufficient and excited to raise the frontend bar on a backend-heavy engineering team.

Level. We expect roughly 4+ years of experience, with independent product-building ability.
