Senior Growth Engineer — AI / PLG
San Francisco, CA / Bay Area — Hybrid
Full-Time | $225K–$290K + Competitive Equity
Build the Growth Engine for a Fast-Growing AI Platform
We are building the infrastructure that turns the web into data AI agents can use. With 8-figure ARR, 147K+ GitHub stars, and rapid year-over-year growth, we're looking for a Senior Growth Engineer to turn developer discovery into activation, adoption, and revenue.
This is not a growth marketing role. You'll write production code and own the engineering behind signup, onboarding, activation, conversion, and PLG experiments—with success measured by the metrics you move.
What You'll Do
- Own growth surfaces end-to-end: signup, onboarding, activation, upgrade and conversion
- Design, build, and analyze A/B tests and product experiments
- Instrument funnels and use SQL/product analytics to identify growth opportunities
- Build full-stack experiences across React, Next.js, TypeScript, Node.js and PostgreSQL
- Partner directly with leadership to shape the PLG growth roadmap
- Rapidly ship, measure, learn, and iterate based on real user behavior
- Leverage AI coding tools and LLMs to accelerate product development
What We're Looking For
- 5–12 years of full-stack engineering experience, ideally in an early- or growth-stage startup
- Proven ownership of PLG features such as onboarding, activation, upgrade flows, or conversion experiences
- Demonstrated ability to move a measurable growth metric
- Hands-on experience designing and running A/B tests and growth experiments
- Strong proficiency in React, TypeScript, Next.js, and Node.js
- Experience with event tracking, SQL, funnels, and product analytics
- Production experience with LLMs / AI-native development
- Daily proficiency with AI coding tools such as Cursor, GitHub Copilot, or Claude Code
- Strong product instincts and ability to operate independently without a detailed spec
- Experience building developer-facing products, APIs, SDKs, playgrounds, or developer tools
- Proven track record of meaningful tenure and seeing projects through
Nice to Have
- Experience with Vercel, Tailwind CSS, Python, PostgreSQL
- Experience with Anthropic Claude API / LLM APIs
- Experience with Datadog, Mixpanel, Amplitude, or PostHog
- Growth engineering experience at a developer tools, SaaS, or AI company
- Experience building internal growth/product tooling
Not a Fit If You Are
- Primarily a growth marketer, SEO/content, CRM/lifecycle, or GTM professional
- A frontend-only or backend-only specialist
- A platform/research engineer without strong product instincts
- Someone who has shipped features without owning measurable outcomes
- Someone who treats AI coding tools as optional rather than part of their daily workflow
