Lead Growth Engineer

Salary: £140K - £250K + Equity

Company Description: Fast-growing AI productivity startup

Job Description:
You will lead product-led growth by owning the strategy and execution of growth loops. Working independently without PMs, you'll leverage a modern TypeScript stack to build experiments across onboarding and monetization journeys. This high-intensity role offers the chance to scale a top-ranked AI application toward its goal of $100M ARR.

Location: London, UK

Why this role is remarkable:

  • Join a company ranked among the top global AI applications based on real startup spending data.

  • Exceptional growth trajectory, scaling from $1M to $30M ARR in a single year with a lean technical team.

  • Total ownership of growth strategy and implementation without the bureaucracy of product managers.

What you will do:

  • Autonomously design and implement experiments to improve viral loops and product-led growth mechanics.

  • Analyze qualitative and quantitative data from Metabase and PostHog to prioritize high-impact backlogs.

  • Build and optimize full-stack features using a serverless TypeScript, React, and Firebase architecture.

The ideal candidate:

  • Proficient in TypeScript and React with the ability to function as a high-velocity full-stack engineer.

  • Proven track record in growth engineering, including optimizing customer journeys and revenue operations infrastructure.

  • Strong background at early-stage tech companies or as a founder with a deep interest in AI agents.

We never post fake jobs
This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.
Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
We appreciate this can make them look a bit suspect, but there isn't much we can do about it.
Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
