ABOUT THE ROLE

We are looking for a Senior Backend Engineer to build and scale the backend of a high-traffic gaming companion site.

The mandatory requirements are 5+ years of backend development with TypeScript on Node.js, PostgreSQL or MySQL, Redis caching, REST and GraphQL APIs, daily use of AI coding tools, and an upper-intermediate English level.

WHAT YOU WILL DO

- Build and maintain REST and GraphQL APIs in TypeScript (Fastify, Hono) for user profiles, subscriptions and game data, including authentication, rate limits and typed contracts.

- Design schemas and write queries for PostgreSQL and MySQL (Prisma, Drizzle), including versioned game data, player builds and migrations on tables in live use.

- Run ClickHouse analytics pipelines: request logs, materialized views, article and revenue metrics, and the queries behind dashboards.

- Own the cache layers end to end: Redis-compatible stores, query caching, tag-invalidated cache, HTTP headers and CDN purges.

- Build and run scheduled jobs and queue consumers (NATS) for game data sync, leaderboards, Meilisearch indexing, sitemaps, Stripe webhooks, payouts and data-deletion requests.

- Integrate third-party APIs (Stripe, Discord, Blizzard, IGDB, Steam, YouTube), handling retries, backoff and rate limits.

- Process game images into map tiles, sprite sheets and responsive image sizes.

- Keep responses lean for Remix and Next.js pages to improve time to first byte, PageSpeed and SEO.

- Work with AI coding agents every day: direct them, review their output, and maintain the guardrails that make their changes safe to merge (tests, lint rules, build checks, agent instructions).

- Deploy through Docker, GitHub Actions and Kubernetes.

- Support high-traffic game launches, including outside regular hours when needed.

- Comfortable reading and changing React code when a feature reaches the frontend.

- Able to work well in a startup-style, fast-paced environment with changing priorities.

- Flexible about working hours: some game launches happen in the evening or on weekends and need coverage outside the standard 9-to-5.
