Original job description

Senior Founding Full Stack Engineer | AI Voice Agents

San Francisco, CA | On-site, 5 days a week | $200K–$280K base + equity

Build the future of AI-powered customer conversations

We're partnering with a profitable, venture-backed AI company in the San Francisco Bay Area that's transforming enterprise customer service through advanced, voice-based AI agents.

With a team of fewer than 50 people, the company is building production-ready AI solutions for major U.S. enterprises. This is an opportunity to join a small, high-impact engineering team where your work directly shapes the product, architecture, and technical direction of the business.

The Opportunity

As a Senior Founding Full Stack Engineer, you'll take end-to-end ownership of core product features, from architecture and development to deployment in production.

You'll work directly with the founders to build high-performance applications and the infrastructure powering real-time AI voice interactions. This role is ideal for an engineer who combines strong frontend expertise with solid backend skills and thrives in a fast-paced, early-stage environment.

What you'll do:

Design and build core features for AI voice agents, including prompt orchestration, real-time dashboards, and analytics platforms.
Develop high-performance frontend applications using React and TypeScript.
Build backend services, APIs, and integrations supporting enterprise-scale customer conversations.
Integrate telephony and real-time communication systems.
Own the full software development lifecycle, from system design to production deployment.
Optimize application performance, state management, and real-time data visualization.
Work directly with founders and enterprise customers to deliver reliable, production-ready solutions.

What We're Looking For

3–8 years of professional experience in full-stack software engineering.
Strong expertise in React and TypeScript, particularly in building performant frontend applications.
Solid backend engineering experience; programming language is flexible.
Proven ability to own features end-to-end, including architecture, API development, and deployment.
A Bachelor's degree in Computer Science or Computer Engineering from a top-tier academic program, with a minimum GPA of 3.8/4.0 or equivalent.
Willingness and ability to work on-site in San Francisco, five days per week.

Nice to Have

Experience with voice, telephony, or real-time communication technologies such as Twilio, SIP, or WebRTC.
Experience building products powered by LLMs or AI agents.
Experience as an early engineer at a fast-growing startup.

Compensation & Benefits

$200,000–$280,000 annual base salary
0.25%–0.45% equity
100% employer-paid medical, dental, and vision insurance.
$10,000 relocation package.
Visa sponsorship available for eligible candidates under H-1B, TN, L-1, E-3, and O-1 categories.
Daily meal allowance and reimbursements for gym, commuting, phone, and internet expenses.

Why Join?

You'll have the opportunity to shape a core AI product, work directly with company founders, and make meaningful technical decisions in a small team where engineering has a direct impact on business outcomes.

If you're a strong full-stack engineer who enjoys building from the ground up and shipping production-grade AI products, we'd love to hear from you.
