Is this job info correct?

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.


Benefits

  • 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


This role is recruited by Jack (hirewithjack.ai). Apply here and we'll reach out to set up a quick 15 minute call.
