TryHackMe is the fastest-growing online cyber security training platform. Our mission is to make learning and teaching cyber security easier by providing gamified security exercises and challenges. We’ve grown to more than 6+ million community members and our growth isn’t slowing down!
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.
Benefits & Perks
- Salary - We hire across 35+ countries. We determine salaries based on geographic location, seniority, interview performance, and market rates using leading compensation benchmarking tools.
- 100% Remote - In a fully digital world, work from anywhere you want!
