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.

MUST HAVES

- 5+ years of backend development with TypeScript on Node.js.

- Strong command of TypeScript’s type system (generics, inference, discriminated unions, narrowing).

- Schema validation experience with Zod or similar.

- Strong SQL skills in PostgreSQL and/or MySQL: schema design, indexing, query plans, migrations on live data, transactions and locking.

- Experience running an analytical database at production volume (ClickHouse preferred; BigQuery, Druid or similar also count).

- Experience designing caching: Redis or a compatible store, invalidation strategies, HTTP cache headers, CDN behavior.

- Experience designing and consuming REST and GraphQL APIs, including authentication and rate limiting.

- Experience with background jobs and message queues, including handling jobs that run twice or don’t run at all.

- Experience with high-volume, user-facing production applications.

- Experience taking a product from idea to production.

- Proficiency with agentic AI coding tools (Claude Code, Cursor or similar): daily, hands-on use in a real codebase, and good judgment about when their output needs checking.

- 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.

- Passion for gaming.
