Member of Technical Staff, Hark Web
Hark, San Jose +1
What you will do
- Design and build the product surfaces of Hark. The interfaces, conversations, and agentic experiences that users interact with every day across voice, text, and vision.
- Work closely with designers to ship interactions that feel fast, reliable, and genuinely useful. The details matter here.
- Own features end-to-end, from early prototyping to production deployment and iteration based on real usage.
- Build the frontend for agent workflows that integrate tool use, memory retrieval, and multi-step reasoning. Making model capabilities feel coherent and trustworthy to the person using them.
- Instrument and evaluate what you ship. Track quality, gather signal, and improve.
What you need
- Strong frontend engineering fundamentals. You are comfortable building polished, responsive interfaces and you care deeply about how things feel to use.
- Experience shipping consumer products that real people depend on. You understand the gap between a prototype and something someone trusts every day.
