Podsumowanie oferty

Build and scale the backend of Maxroll.gg, a high-traffic gaming companion platform. Work on user profiles, subscriptions, game data, analytics and integrations using TypeScript, Node.js, REST and GraphQL.

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 preferred, with BigQuery, Druid or similar also accepted.
Experience designing caching with Redis or a compatible store, 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 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.
