Podsumowanie oferty

Build and scale the backend of Maxroll.gg, a high-traffic gaming companion platform. Develop APIs and backend services using TypeScript and Node.js, including features for user profiles, subscriptions, and game data.

Wymagania

3+ years of backend development with TypeScript on Node.js.
Strong command of TypeScript's type system, including generics, inference, discriminated unions, and narrowing.
Schema validation experience with Zod or similar.
Strong SQL skills in PostgreSQL and/or MySQL, including schema design, indexing, query plans, migrations on live data, transactions, and locking.
Experience running an analytical database at production volume; ClickHouse is preferred, while BigQuery, Druid, or similar also count.
Experience designing caching with Redis or a compatible store, including invalidation strategies, HTTP cache headers, and 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 do not 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 such as Claude Code or Cursor, including 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 have:

Experience with Bun.
Experience with any of the current stack: Remix, Next.js, Fastify, Hono, Prisma, Drizzle, Apollo GraphQL, Meilisearch, NATS, Ory, Stripe, or Nx.
shadcn/ui and Tailwind CSS.
Strict lint setups, including typescript-eslint strictTypeChecked, custom lint rules, and architecture boundaries.
Docker, Kubernetes, GitOps (ArgoCD), GitHub Actions, and External Secrets.
Payments and subscriptions, including Stripe checkout, webhooks, and 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.

Obowiązki

Build and maintain REST and GraphQL APIs in TypeScript using Fastify and Hono for user profiles, subscriptions, and game data, including authentication, rate limits, and typed contracts.
Design schemas and write queries for PostgreSQL and MySQL using Prisma and Drizzle, including versioned game data, player builds, and migrations on tables in live use.
Run ClickHouse analytics pipelines for request logs, materialized views, article and revenue metrics, and dashboard queries.
Own cache layers end to end, including Redis-compatible stores, query caching, tag-invalidated cache, HTTP headers, and CDN purges.
Build and run scheduled jobs and queue consumers using 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, and 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 daily: direct them, review their output, and maintain guardrails for safe merges, including tests, lint rules, build checks, and agent instructions.
Deploy through Docker, GitHub Actions, and Kubernetes.
Support high-traffic game launches, including outside regular hours when needed.
