Founding Growth Engineer

Description

The company is building the infrastructure that makes AI trustworthy. We help engineering teams evaluate, monitor, and improve the AI systems they ship to production.

We're hiring a Founding Growth Engineer to build our growth engine from scratch: the funnels, experiments, and instrumentation that acquire and activate users and tell us exactly what's working. This is a build-and-measure role, not a content or community role — you'll make decisions based on what the data says, and you'll work in person in San Francisco directly with the founders.

What you'll be doing

Design and build a reusable, scalable growth engine from the ground up — the acquisition channels, funnel stages, experiment framework, and feedback loops that let us grow predictably rather than by luck.

Own the growth funnel end to end, from first touch through sign-up and activation. Map it, instrument it, and find where users leak out.

Build the instrumentation and attribution layer so every channel, page, and experiment can be measured against real outcomes — activated users, not traffic and vanity metrics.

Run a weekly cadence of growth experiments across channels: organic and AI search (SEO/AEO), programmatic pages, lifecycle and onboarding flows, referral loops, and product-led triggers. Ship, measure, double down on what compounds, and kill what doesn't.

Explore video as a growth channel — product demos, short-form clips, and tutorials on YouTube and social — and measure whether it drives sign-ups and activation, not just views.

Build the tooling yourself: data pipelines, dashboards, automation, scrapers, programmatic content systems, and the AI-agent workflows that let one person operate like a growth team.

Turn data into decisions. Analyze funnel performance, cohort behavior, and channel efficiency, and reallocate effort toward what the numbers show is actually driving growth.

Partner closely with the founders. They set direction; you build and scale the system that makes it grow.

You should be someone who

Experience in growth engineering, growth or product analytics, or a technical growth role — someone who builds systems and runs experiments rather than managing agencies or content calendars.

You can code. Comfortable in Python and/or TypeScript/Node, building pipelines, attribution, automation, and internal tooling. You ship your own tools instead of waiting on someone else.

Deeply data-driven. You're fluent in funnel and cohort analysis, know how to set up event tracking and attribution properly, and are honest about what the data does and doesn't tell you. This is the make-or-break trait for this role.

Strong experimentation discipline: clear hypotheses, sensible sample sizes, and the willingness to kill your own ideas when the results say so.

Practical understanding of modern acquisition channels — SEO, AEO/GEO (showing up in AI-generated answers), programmatic content, lifecycle, and product-led growth loops.

Comfortable owning a growth metric tied to real outcomes — activated users, not stars or pageviews.

Technical enough to understand a developer product and the engineers who use it, so the funnels you build make sense to the people going through them.

Comfortable executing within a strategy the founders own, bringing strong opinions while staying in a build-and-execute seat.

High-agency and comfortable with ambiguity. Exceptional early-career candidates are welcome — ceiling matters more than years.

Excited to work in person with the founding team in San Francisco.

Your work will

Build the growth engine from scratch — a repeatable, scalable system for acquiring and activating users that outlives any single campaign.

Own the growth funnel and the metric that comes out of it, from first touch to activation.

Own instrumentation and attribution, so the company always knows what's driving growth and what isn't.

Set the data-driven, experiment-first culture that the future growth team is built on.

By joining us, you will

You're building on a real foundation. Our open-source projects already have serious developer adoption — you're building the engine that turns that into predictable growth, not starting from zero.

Build it your way: full ownership of the growth stack, the tooling, the data layer, and the experiments. If you can code it and it moves the metric, ship it.

A seat at the table with the founding team, a high ceiling, and the foundation of a future growth team to build under you as the company scales.
