Software Engineer - Frontend

We're looking for a Frontend Engineer who wants to be the person writing that code. You'll work in a modern stack — React 19, Next.js 16, TypeScript, TanStack Query, an in-house design system, Storybook + Chromatic + MSW — inside a monorepo of ~14 Subscription-owned packages. You'll ship alongside Product, Design and Backend, on features and experiments that move numbers the whole company watches.

The Team

You'll ship alongside a senior Frontend Engineer — your closest technical partner — plus two Backend Engineers, a Product Designer, a Product Manager and an Engineering Manager. Product and Design own the flows; you and the senior FE own how they land in production.

What You'll Own

• The paid conversion path, end-to-end. Conversion points across the app, the plan landing page, Stripe & Xsolla checkout (including gifting and upgrades), and the immediate post-purchase experience — you'll own the code, the experiments, and the conversion numbers they produce;
• The subscriber lifecycle. Pause, resume, cancel, renewal and the Subscriber Portal — where retention is won or lost. You'll build the flows that reduce voluntary churn without dark patterns and recover involuntary churn cleanly;
• The Loyalty programme UI. Tiers, streaks, XP, payment-anchored benefits, shop token allocation, badges. You'll turn our Loyalty service into an experience players actually understand, care about, and come back for;
• Experimentation velocity. Feature-flagged rollouts, A/B tests on pricing, bundling, activation and cancel-flow interventions, wired to analytics with the rigour to trust the results;
• The technical health of a revenue-critical surface. Testing culture (Vitest + Storybook + Chromatic + MSW), observability, and the safe-rollout discipline that lets us ship confidently to code that processes real transactions every minute.

What We Are Looking For

• Solid production experience with React 19, TypeScript, and Next.js (App Router);
• Fluent with modern data-layer patterns — TanStack Query (or equivalent) and Redux Toolkit — and a clear point of view on when to reach for each;
• Comfortable in a large monorepo: package boundaries, dependency hygiene, incremental migrations, working across many consumers of your code;
• Track record of owning a high-traffic, business-critical surface — checkout, billing, payments or another revenue/retention path — and understanding the operational demands (idempotency, error recovery, race conditions, safe rollout, observability, and the uptime discipline that treats every minute of downtime as lost revenue);
• Strong eye for details of complex state in production: proration, entitlements, expirations, currency and tax, localisation, accessibility. You know the common pitfalls and handle them in code, not in post-mortems;
• Familiarity with experimentation tooling and mechanics: feature flags, segmentation, A/B tracking, and the instrumentation that makes results trustworthy;
• Solid on testing culture — unit, component and visual regression. You don't ship revenue code without a safety net;
• Collaborative by default: fluent code review, clear writing, low-ego debates, comfortable partnering with Product, Design and Backend as equals;
• Fluent with modern AI coding tools (Copilot, Cursor, Claude Code or similar) as part of your daily practice — and clear-eyed about when to lean on them and when not to, especially on revenue-critical code.

Bonus skills

• Passionate about learning new, cutting-edge technologies and finding applicable business cases as needed;
• A passion for video games and esports is a plus.
