Lead Developer Evangelist, Voice AI (SF)

Lavendo partners with startups and high‑growth companies to help them hire top‑tier sales, GTM, and technical talent. This role is with one of our clients; we’ll share full details about the company and interview process as we get to know you and confirm mutual fit.

About the Company

Our client is an AI company headquartered in San Francisco, backed by $9.6M in seed funding. They build and deploy frontier voice AI models — the voice equivalent of what OpenAI and Anthropic do for language — delivered via cloud API or fully on-prem, slotting directly into customers' existing orchestration stacks.

Their models drive 15%+ call success rates, 23%+ increased sales, and 25%+ IVR containment for companies ranging from high-growth startups to Fortune 500 brands. Usage-based pricing. Real customers. Real results.

The Mission

Make voice AI feel human. The team brings deep linguistic and machine learning expertise to close the gap between how machines sound and how people actually speak — with warmth, authenticity, and emotional nuance built into every model.

The Opportunity

As a Lead Developer Evangelist, you'll own how developers discover, evaluate, and adopt the product — online and in person. You'll work directly with the Head of Marketing and have close access to the CEO and product team. There's no content calendar waiting for you, no playbook to execute, and no team to manage before you've proven yourself. What there is: a company at a high-growth inflection point, a developer audience that hasn't been properly reached yet, and full creative latitude to go build that.

What You'll Do

- Define and execute the developer community strategy — start from scratch, replace what isn't working with something developers actually want to be part of

- Create original video content: tutorials, demos, builds, hot takes — on the platforms where voice AI developers actually spend time

- Show up at hackathons, meetups, and conferences as the face of the company in developer conversations

- Build reference apps, open-source tools, and demos in public — the kind of work that gets shared

- Write content that engineers actually want to read, on the company blog and your own channels

- Surface developer feedback directly to the product and engineering teams

- Develop a 6-month strategy for events, talks, and partnerships — then execute it

- Propose your own cadence. No one will hand you a schedule

What You Bring

- 4–8 years working in developer evangelism, DevRel, or developer-facing content at early or growth-stage startups

- A public body of work you can share right now: YouTube, X/Twitter, Substack, GitHub, or some combination, with a developer audience

- Technical fluency — enough to build with APIs, debug a webhook, and explain how a voice agent stack fits together. You don't need to be a senior engineer, but you need to be able to build

- Equally comfortable on camera and on stage

- Based in the SF Bay Area

- Authorized to work in the US — no visa sponsorship available

Key Success Drivers

- You publish consistently — a regular, living body of work

- You have a point of view — strong opinions about voice AI and dev tools, shared publicly

- You operate without a playbook — you can walk in and tell the team how you'd make this company unmissable to developers

- You bring founder energy — you prioritize ruthlessly, move fast, and ship

Why Join

- Compensation: $180,000–$230,000 base, plus a competitive equity package

- Hybrid work: No hard office requirement — be in the Bay Area and available for in-person collaboration when it matters

- Creative ownership: You'll build developer evangelism from the ground up with direct access to leadership and the product team

- Timing: Seed-funded at a high-growth inflection point, with major announcements coming. The company is scaling fast and the developer audience hasn't been fully unlocked yet

- Culture: ~40-person team that values craft over hype, moves with autonomy, and doesn't hide behind process

Interviewing Process

- Initial Screen with the VP of Marketing

- Sync with the Developer Evangelist

- Take-Home Exercise (no more than 1 hour) + Take-Home Review

- In-person interview with the Founder/CEO

- Offer
