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.

• Upper-intermediate English level.

NICE TO HAVES

• Experience with Bun.

• Experience with any of the current stack: Remix, Next.js, Fastify, Hono, Prisma, Drizzle, Apollo GraphQL, Meilisearch, NATS, Ory, Stripe, Nx.

• shadcn/ui and Tailwind CSS.

• Strict lint setups (typescript-eslint strictTypeChecked, custom lint rules, architecture boundaries).

• Docker, Kubernetes, GitOps (ArgoCD), GitHub Actions, External Secrets.

• Payments and subscriptions (Stripe checkout, webhooks, promotion codes).

• Writing agent instructions, skills or custom tooling for AI coding agents.

• Experience building game tools, such as databases, interactive maps, calculators or planners.

PERKS AND BENEFITS

• Professional growth: Mentorship, TechTalks, and personalized growth roadmaps.

• Competitive compensation: USD-based pay with education, fitness, and team activity budgets.

• Exciting projects: Modern solutions with Fortune 500 and top product companies.

• Flextime: Flexible schedule with remote and office options.
