Job description

We're hiring a Senior Frontend Engineer for one of the fastest-growing voice AI startups in the world. You'll build the product customers use every day to run their voice agents: dashboards, analytics, prompt management and customer-facing tools. Small, high-ownership frontend team that reports directly to the CTO.

Location: On-site in Redwood City, CA. This team works a 996 schedule (in office Monday to Friday, Sunday remote). Please only apply if that works for you.

Comp: $200K to $300K base plus competitive equity. Visa sponsorship and relocation available.

What you'll do

• Ship React-heavy features end to end, from prompt management to dashboards and analytics
• Write production React and TypeScript by hand
• Work with backend and full-stack engineers on a team of about 7 frontend-focused devs
• Talk to customers directly to onboard them, debug issues and turn feedback into UX improvements
• Own frontend architecture decisions and move fast

What we need

• Bachelor's or master's in Computer Science, Computer Engineering, Computational Science or Electrical Engineering
• 2+ years of professional engineering experience after graduation, and you're working as an engineer right now (we need recent hands‑on coding, so time spent on a new degree doesn't count toward this)
• Current title of Software Engineer, Frontend Engineer, FDE, Solutions Engineer or Product Engineer
• Expert-level React. You can build without AI help
• Production TypeScript and Node.js
• 1.5+ years at a VC‑backed startup, and ideally time at a well‑known tech company or high‑growth YC startup

Heads up on the interview

there's a live coding screen with no AI tools allowed. If that's not your thing, this role isn't a fit.

• 100% covered medical, dental and vision
• $70/day DoorDash credit for meals
• $200/month wellness, $300/month commuter, $75/month phone and $50/month internet stipends
• Choose your own cash and equity mix
