Software Development
React.js, Front End Developer, Full Stack Developer
Job Description:
This is a rare opportunity to join one of the fastest-growing voice AI startups, recently scaling from $5M to $80M ARR with a small, high-ownership engineering team. If you want to own major product features, work directly with customers, and help shape the frontend at a company recognized by Y Combinator, a16z, and more, this could be your next big step.
What You Will Do
Build and ship React-heavy frontend features end to end, including prompt management tools, dashboards, and analytics.
Write production-grade React and Type Script code live, without AI assistance. This is a must, and interviews include live React coding.
Collaborate closely with backend and full-stack engineers on a team of about seven frontend-focused developers.
Work directly with customers to onboard them, debug issues, and turn their feedback into real UX improvements.
Own major frontend architecture decisions and iterate quickly in a fast-paced, high-growth startup environment.
Report directly to the CTO (a co-founder) and have outsized ownership on a small team.
What Is Expected
You have 3-7 years of professional frontend engineering experience, with at least 3-5 years hands-on with React.
You are currently working as a frontend engineer with React at your core.
You can write expert-level React without relying on AI tools. This is non-negotiable.
You have production Type Script experience, and Node.js is a plus.
You have spent 1.5+ years at a VC-backed startup, and held at least one role at a well-known tech company or high-growth YC startup.
You hold a B.S. in Computer Science, Computer Engineering, or Electrical Engineering from a top-tier university (or have strong YC/top-company experience).
You can work on-site in Redwood City, CA, Monday to Friday, plus remote Sundays (6-day work schedule).
What Is Offered
$200K to $300K base salary plus meaningful equity.
100% medical, dental, and vision coverage.
$70/day Door Dash credit and $200/month wellness reimbursement.
Visa sponsorship and transfers (H-1B, TN, L-1, E-3, F-1 OPT/CPT, O-1), plus relocation support.
High ownership and direct impact, reporting to the CTO, in a small, ambitious team.
