Descrizione del lavoro

AgileEngine is seeking a Senior Backend Engineer to build and scale the backend of a high-traffic gaming companion site. The role requires 5+ years of backend development with TypeScript on Node.js, PostgreSQL or MySQL, Redis caching, REST and GraphQL APIs, and an upper-intermediate English level.

You will design schemas for live data, run analytics pipelines with ClickHouse, own cache layers end-to-end, and integrate Stripe, Discord, Blizzard, IGDB, Steam and YouTube APIs.

Competenze

• 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 frontend feature is implemented.
• Able to work 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 9–5.
• Passion for gaming.

Mansioni

• 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 daily: direct them, review their output, and maintain guardrails for 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.
