Job description

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‑Hold
• 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.
