Play. Bet. Win. Welcome to PlayVersa.
We're a small, senior team that ships. You'll have real ownership from day one.
The role
We're hiring a Senior Full-Stack Developer to help take our web games to the next level — building new gameplay, tightening performance, and growing the services behind accounts, scores, and matchmaking.
You'll work across the whole stack: the React front end, the HTML5 canvas game engine, and the Node/Express + SQLite backend that powers it all.
What you'll do
- Design and build new game features and polished, responsive UI in React + TailwindCSS.
- Write and optimize HTML5 Canvas game logic — physics, input, rendering, and a smooth 60 fps loop.
- Build and maintain backend services: REST APIs, authentication, persistence, leaderboards.
- Profile and fix performance bottlenecks across load time and interaction (large lists, render cost, network waterfalls).
- Own features end-to-end — from spec, through implementation and testing, to release.
- Raise the bar on code quality through reviews, sensible architecture, and pragmatic tests.
Tech stack
You don't need every item, but you should be strong in most of it:
- Front end: React 18 (hooks, context), Vite, TailwindCSS, modern JavaScript (ES2022+)
- Game/graphics: HTML5 Canvas 2D, `requestAnimationFrame` game loops, basic 2D physics
- Back end: Node.js, Express, REST API design
- Data & auth: SQLite (or similar), password hashing/sessions, secure auth flows
- Tooling: Git, npm, browser dev tools / profiling
What we're looking for
- 5+ years building production web applications, with real front-end depth.
- Fluency in React and modern JavaScript; you understand rendering, state, and re-render cost.
- Experience building and consuming HTTP APIs and working with a relational store.
- A track record of diagnosing performance problems with data, not guesswork.
- Care for UX and visual polish — you notice jank and fix it.
- Clear written communication and the self-direction to own work in a small team.
Nice to have
- Shipped a game or interactive/animation-heavy app on the web.
- Canvas/WebGL, audio, or real-time (WebSocket) experience.
- Security mindset for auth, sessions, and input validation.
- TypeScript.
What we offer
- [Competitive salary + equity/bonus]
- [Remote-first / flexible hours]
- [Health, learning budget, hardware, PTO — fill in]
- Small team, high ownership, real players using what you ship.
Take-home assignment
Strong candidates are invited to a paid / time-boxed take-home (~[3–4] hours)
built on a slimmed-down version of our real Moto Stunt Riders codebase
(React + Vite + Tailwind on the front end; Node/Express + SQLite on the back end).
You'll receive the repository with a short TASK.md. Typical assignments include:
1. Performance — The garage screen renders thousands of bikes and the search / sort / favorite interactions lag. Find *why* (measure, don't guess) and make it smooth without changing behavior.
2. Feature — Add a self-contained feature end-to-end (e.g. a new gameplay mechanic, an API endpoint + UI, or an auth improvement) that fits the existing architecture.
We evaluate:
- Correctness & UX — does it work, and does it feel good to use?
- Problem-solving — for perf tasks, did you *measure* the real bottleneck?
- Code quality — clear, consistent with the codebase, appropriately tested.
- Communication — a short write-up of your approach, trade-offs, and what you'd
do next with more time. A before/after measurement (numbers or a short clip) is a plus.
Please keep changes scoped to the task, and don't rewrite unrelated code.
How to apply
Send your CV / portfolio and a few lines on a web project you're proud of. GitHub profile is accepted.
We welcome applicants of all backgrounds and don't discriminate on any protected characteristic.
