Growth Engineer

Company Description: AI-driven fintech platform building operating systems

Job Description:
You will lead the company’s experimentation engine, moving from hypothesis to proof-of-concept in days. By working across the full stack with Django, React, and LLM integrations, you will build and validate new growth wedges. Your work directly influences the product roadmap by identifying what users value through rapid prototyping and data-driven learning.

Location: London, UK

Why this role is remarkable:

• Direct impact on the "Speed of Learning" engine of a fast-moving AI startup

• Highly autonomous environment where you are encouraged to fail fast and kill ideas based on data

• Backed by top-tier VCs and focused on a massive market opportunity in financial services

What you will do:

• Build end-to-end POCs in days using Django, React, and LLM integrations to test specific hypotheses

• Talk directly to users and design partners to translate customer pain points into testable experiments

• Instrument and analyze experiment data to validate or pivot product features before full-scale production

The ideal candidate:

• 4-7 years of software engineering experience in high-growth startups or as a former founder

• Full-stack proficiency in Python/Django and React/TypeScript with a history of shipping AI/LLM features

• Strong product sense and experimentation mindset that prioritizes validation over technical perfection

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.
