Growth Engineer

We want to build agents that autonomously validate code changes. Today that looks like AI that reviews pull requests in GitHub, catching bugs and enforcing standards. We’re reviewing close to 1B lines of code a month now for over 3,000 companies.Problems We’re Excited AboutCoding standards can be idiosyncratic and are often poorly documented; can we build agents that learn them through osmosis like a new hire might?Can we identify for each customer what types of PR feedback they do and don’t care about, perhaps using some sample efficient RL, in order to increase signal-to-noise ratio?Some bugs are best caught by running the code, potentially against discerning AI-generated E2E tests. Can we autonomously deploy feature branches and use agents to parallel try to break the application to detect bugs?Trajectory7,000+ customersRaised $30M from Benchmark, YC, Paul Graham, InitializedTeamWe have assembled a small, talent dense team who have scaled critical functions at companies like Stripe, Google, Figma, etc. ResponsibilitiesOwn and ship growth-critical engineering projects end-to-end, from identifying opportunities to building, launching, and iterating based on resultsDesign, build, and run experiments across the full user journey, spanning the marketing website, onboarding, activation, and product interactionsPartner closely with product and growth teams to scope ideas and ship high-quality, production-ready implementationsBuild and own the core analytics and attribution framework, including event instrumentation, dashboards, and reporting used to guide decisionsDefine and track clear success metrics (e.g. activation, conversion, retention), and use data to decide what to double down on or stopWork across the stack (frontend, backend, and data) to ship pragmatic solutions that meaningfully move key metricsBalance fast, iterative experimentation with higher-conviction projects, owning technical execution in both casesQualificationsStrong software engineering foundation (frontend, backend, or full-stack)Experience building and shipping user-facing product or web featuresComfort working with data, metrics, and experimentation to inform decisionsSolid product intuition and curiosity about how users discover, adopt, and stick with productsAbility to move quickly, take ownership, and learn through iteration without sacrificing code qualityFamiliarity with modern web stacks and analytics toolingInterest in how products grow across channels (e.g. paid acquisition, SEO, lifecycle email), and eagerness to learn how engineering decisions shape outcomesBonus: experience with developer tools, product-led growth, or B2B SaaSCompensation Range: $130K - $190K
