Resumo da vaga

AgileEngine is seeking a Senior Backend Engineer to build and scale the backend for a high-traffic gaming companion site. You will work with TypeScript on Node.js, REST and GraphQL APIs, and modern data stores.

You will design schemas for PostgreSQL/MySQL, manage Redis caches, run analytics pipelines with ClickHouse, and integrate with Stripe, Discord, and other third‑party services. The role requires 5+ years of backend experience and an upper‑intermediate English level.

Qualificações

• 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, queries on live data.
• Experience with analytical databases at production volume (ClickHouse preferred).
• Experience designing and consuming REST and GraphQL APIs, including authentication and rate limiting.
• Experience with caching: Redis and CDN behavior.
• Experience designing and consuming background jobs and queues.

Responsabilidades

• 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.
