Jobbeschreibung

Build the Future of Cyber Security Learning at Scale

Join TryHackMe as a Senior Full-Stack Engineer. We are a fast-growing, highly profitable cybersecurity training platform trusted by over 9 million learners and 1,000+ enterprise organisations globally, including Google, KPMG and the US Military.

Whether you’re building gamified learning mechanics for millions of individual users, scaling enterprise-grade B2B management tools, or hardening core payment and cloud infrastructure, you’ll join a high-autonomy, high-velocity engineering squad where your decisions directly impact real users from day one.

Location / Time Zone: 100% Remote (UK / EU based with strong overlap with UK business hours required).

The Stack & Engineering Culture

• Core Stack: TypeScript, React, Next.js, Node.js, Express, MongoDB
• High Velocity: We operate as a high-trust, high-autonomy team shipping 250+ PRs per week
• Pragmatic AI Workflow: We actively leverage modern AI development tools (Cursor, Claude Code, Codex) to accelerate execution

Our Squads & What You’ll Own

You will be embedded in a small, cross-functional squad (engineers, product manager, designer) with end-to-end ownership. Based on your background and interests, you’ll make an impact in one of our core product areas:

• B2B Squad: Build the platform that turns entire organisations into cyber-resilient teams. Own enterprise SSO, granular RBAC, licensing engines, custom syllabus mapping, and CISO-ready skill analytics.
• Engagement Squad: Shape the learner journey for 9M+ users. Own progression mechanics, leagues, streaks, personalised discovery, and A/B experiments that turn first-time visitors into lifelong learners.
• Platform Squad: Own the high-leverage infrastructure every squad depends on. Scale payment rails (Stripe), cloud VM delivery tools, internal support systems, and cross-cutting platform performance.
• Certification Squad: Building best-in-class certifications that validate our learners’ skills and recognise the time and commitment they invest in learning, working closely with Product, Marketing and our in-house Content Engineering team.

Day-to-Day Responsibilities

• End-to-End Ownership: Take ambiguous, loosely defined product problems from initial concept through design, implementation, and production deployment.
• Architecture & Craft: Design scalable, reliable, and secure RESTful APIs and modern frontend interfaces, keeping long-term maintainability and system performance in mind.
• Cross-Functional Partnering: Work directly alongside product managers and designers to shape how problems get solved, not just pick up pre-written tickets.
• Engineering Leadership: Elevate squad quality through thoughtful code reviews, system design discussions, and mentoring fellow engineers.
• Product Curiosity: Validate what works using data, user feedback, and experimentation rather than relying on opinions.

What You’ll Bring

• Core Technical Mastery: Strong commercial full-stack experience building production SaaS applications with advanced TypeScript, Node.js, React and MongoDB/SQL fundamentals.
• Product Engineer Mindset: You care deeply about user impact and business outcomes, not just backend plumbing. You prefer shipping real value quickly over endless corporate red tape.
• High Ownership & Autonomy: Comfort working in fast-paced environments where you take full accountability for your features, from database schemas to UI polish.
• AI-Assisted Efficiency: Experience using modern AI dev tools (Cursor, Claude) to move faster, combined with the technical judgment to critically evaluate and test generated code.
• Clear Communication: Ability to explain complex technical trade-offs clearly to both technical and non-technical teammates.
• Bonus Points: A genuine interest in cybersecurity, online education or an active TryHackMe profile you're proud of!

Why TryHackMe?

• High Impact & High Autonomy: Work in a small team where your code directly reaches millions of users and global enterprises, not lost inside a 500-person engineering department.
• Elite Sports Team Mindset: We foster a candid, direct feedback culture built on rapid execution, high trust, and extreme ownership.
• Profitable & Fast-Growing: Enjoy the velocity of an early-stage scale-up backed by the stability of a highly profitable, self-sustaining business.

Benefits & Perks

• 100% Remote: Work from anywhere within the UK or approved EU regions.
• Top-Tier Tools: Latest MacBook Pro + budget for any workspace accessories you need.
• Swag Bundle: Start your journey with exclusive TryHackMe gear.
• Personal Development: £2,500 annual training budget for certifications, courses, and conferences.
• Company Retreat: Fully paid annual company-wide retreat.
• Lunch on Us: Covered during recurring virtual team lunches.
• Health Insurance: Provided in regions without universal coverage.
• Enhanced Leave: Generous maternity and paternity packages.
• Pension / 401(k): Company contribution options for retirement savings.
