Founding Frontend Engineer

Ciridae is looking for a Founding Frontend Engineer who is product-minded and possesses elite craft skills. The role involves owning the frontend layer of their proprietary platform, Crucible, and ensuring that complex AI systems are turned into intuitive and usable software.

Responsibilities:

• You take a loosely defined need, identify the right workflow, prototype it, make the design calls, and carry it through to production independently
• 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
