We’re growing to be an AI-first company, you can read more about what this means here.

The Role

We’re looking for a Growth Software Engineer to join our cross-functional Growth teams. You’ll blend full-stack engineering with experimentation - shipping code that directly moves acquisition, activation, and retention metrics.

You’ll work closely with Product Managers, Designers, and Data Analysts to ideate, build, and measure experiments - from SEO and onboarding flows to referral loops and pricing tests - all while maintaining high technical standards in our MERN + TypeScript codebase.

What You’ll Do

• Design, build, and ship growth experiments end-to-end - from hypothesis to measurable impact.

• Work across our stack (React, TypeScript, Node.js, MongoDB) to deliver experiments and potential big-bet features - anything needed to move the needle.

• Translate data into code: partner with Product and Data to identify insights, prioritise opportunities, and build solutions that move key funnel metrics.

• Optimise user journeys - activation flows, conversion funnels, and re-engagement loops.

• Instrument and measure everything: implement analytics, event tracking, and A/B test frameworks.

• Get things shipped fast - with just enough structure to keep the code clean, maintainable, and ready to scale.

• Stay curious: research new tools, frameworks, and techniques to enhance velocity and impact.

Skills & Requirements

Must-Have

• 5+ years of software engineering experience (full stack).

• Strong proficiency with React, TypeScript, and modern front-end tooling.

• Backend experience with Node.js, Express, and MongoDB / Mongoose.

• Understanding of scalable application design and clean architecture principles.

• Experience with A/B testing, feature flags, or experimentation frameworks.

• Comfortable using tools like Amplitude, Segment, and GrowthBook to track impact, manage feature flags, and inform decisions.

• Must have a bias for action - able to move fast while keeping code reliable through smart testing, reviews, and documentation.

Nice to Have

• Familiarity with growth engineering principles (funnels, loops, retention mechanics).

• Experience working closely with Product and Data teams to interpret and act on insights.

• Knowledge of SEO, onboarding optimisation, or internal growth tooling.

• Experience using AI tools (Cursor, Claude, MCP’s, ChatGPT, etc.) to improve engineering velocity.

• Understanding of UX, accessibility, and performance optimisation

About You

• You’re curious and data-driven, always asking “why?” before “how?”.

• You’re excited by rapid iteration and measurable impact.

• You collaborate naturally across disciplines and communicate clearly.

• You take ownership - from shaping experiments to seeing them through to production.

• You balance speed with technical excellence - pragmatic, not reckless.
