Growth Engineer
Job description
Fullstack Engineer on the Growth team at Peec AI, running growth experiments across the self-serve journey from first touch through signup, pricing, checkout, trial, onboarding and in-product prompts.

What you'll do
- Go after big swings, sizing every idea first and looking for changes that could move a funnel step by 30 to 40 percentage points
- Build and improve the experimentation infrastructure: feature flags, assignment at the account level, exposure logged when someone becomes eligible, outcomes recorded on the server, and holdouts
- Keep conversion data accurate through event design, funnel definitions and reliable readouts
- Own what you ship after launch: watch it, read the result on the date you set, and decide whether to keep, change or remove it
- Build internal tools that let the team run more experiments with less manual work
- Come up with the hypothesis, design the experiment and discuss it with the team, then build it, instrument it, ship it behind a flag, read the result and write down what happened
What we're looking for
- You have run growth experiments end to end: formed the hypothesis, designed the test, built it and read the result
- You write production code today: strong React and TypeScript on the frontend, comfortable in Node.js and databases on the backend
- You know what your volume can detect: can size a test, say how long it needs to run, and tell when a result is not readable
- SQL and analytics fluency: funnels, cohorts, event design
- B2B SaaS experience
- You ship with Claude Code, Cursor or equivalent
- Product judgement: can tell which changes need a test, which can ship without one, and which are not worth building
- Product taste: care about how the things you ship look and feel, can turn an idea into a screen that belongs in the product, and know when to bring in the design team
Nice to have
- You set up an experimentation practice from scratch and grew it into a regular part of how the team works
- Product-led growth experience: onboarding, activation, paywalls, pricing, checkout
- Acquisition experience: website and signup experiments, SEO or paid funnels
- Experiments on low-volume B2B funnels, where only big changes are readable
- Experimentation platforms and feature flags: Statsig, GrowthBook, PostHog, or your own
- Billing and subscriptions: Stripe or similar
- You founded a company, or you were an early engineer at one
- Side projects and experiments you can show us
