Are you the kind of engineer who sweats the details, the race condition nobody else noticed, the retry that could double-charge a user, the edge case hiding in a timeout? Do you have your own opinions about how systems should be designed, and enjoy defending them with reason rather than rank? Do you like working with a tight-knit core team, tackling problems where early exploration becomes long-term wins for the studio? If that sounds like you, we would love to hear from you. We are a game development studio expanding from game development to operating our own gaming platform and we're looking for an engineer to build it with us from the ground up. This is a high-scope, greenfield role. There is no legacy system to babysit and no spec handed down from above. You will help define the architecture, make the trade-offs, and live with the consequences. The APIs you design will become long-term contracts for third-party integrators, and the accounting code you write will handle real money. Responsibilities * Design and build the platform's core wallet/ledger system, ensuring transactional correctness and idempotency across the full transaction lifecycle * Design public-facing APIs for game studios and platform partners: authentication and request signing, error code conventions, versioning, callback and retry strategies * Build high-concurrency real-time services: persistent connection management, low-latency transaction pipelines, capacity planning, and load testing * Drive observability: monitoring and alerting, distributed tracing, production incident response and postmortems * Shape the platform's technical direction: propose, challenge, and own architectural decisions, not just implement them ## Related Videos - [Inside Bitpanda's Tech Stack: Scaling a European Fintech Leader - Markus Dorner](https://www.wearedevelopers.com/videos/1979-inside-bitpanda-s-tech-stack-scaling-a-european-fintech-leader-markus-dorner) - [The Power of Purpose: Unlocking Potential and Innovation](https://www.wearedevelopers.com/videos/1110-the-power-of-purpose-unlocking-potential-and-innovation) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Optimizing Discovery: PostgreSQL's Role in Transforming GetYourGuide's Search](https://www.wearedevelopers.com/videos/1647-optimizing-discovery-postgresql-s-role-in-transforming-getyourguide-s-search) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) - [Next Level Enterprise Architecture: Modular, Flexible, Scalable, Multichannel and AI-Ready?](https://www.wearedevelopers.com/videos/1017-next-level-enterprise-architecture-modular-flexible-scalable-multichannel-and-ai-ready) ## Related Articles - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Dev Digest 132 - Binging WADFlix?](https://www.wearedevelopers.com/magazine/473-dev-digest-132-binging-wadflix) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Dev Digest 131 - AI'm not sure about OSS](https://www.wearedevelopers.com/magazine/472-dev-digest-131-ai-m-not-sure-about-oss) - [The Best X (Twitter) Accounts for Developers](https://www.wearedevelopers.com/magazine/294-the-best-x-twitter-accounts-for-developers)
