Backend Engineer (Gamedev)

TL;DR

Backend Engineer (Gamedev): Build scalable backend systems and support game services through development and live operations with an accent on backend architecture, APIs, game economy systems, and player-facing services. Focus on owning client-server API contract, game economy services, IAP verification, location proximity service, and observability.

Company

hirify.global develops games and requires backend engineers for scalable systems supporting game services.

What you will do

• Own the client-server API contract including surface, versioning, error semantics, and backward compatibility.
• Own game economy services with server-authoritative probability and balance config tooling for Game Design.
• Own IAP verification for App Store and Google Play receipts, idempotent entitlement grants, and duplicate-webhook handling.
• Own location proximity service including coordinate ingestion, inter-player distance, and anti-spoofing.
• Own observability with structured logs, latency/error metrics, on-call runbook, and maintain API/architecture docs.
• Use and document AI tools like Claude, ChatGPT, Gemini for reproducible team workflows.

Requirements

• Layered architecture: domain testable without framework or DB; stateless HTTP, idempotency, consistent error semantics.
• API versioning with deprecation policy; configurable timeouts, retry budgets, pagination limits.
• Integer/fixed-point for all currency ops; anti-abuse: idempotency keys, replay resistance, rate limiting.
• Token-based sessions: issuance, validation, revocation, refresh; no secrets in source or commit history; documented rotation.
• Single IAP interface for both stores; test mock replaceable; env via config.
• Latency budgets: transaction isolation, indexing, N+1; profiling via traces, query plans, load tests; structured logs with correlation IDs; durable async messaging with idempotent consumers.

Nice to have

• F2P live ops, anti-fraud/anti-cheat, feature flags, CI/CD + IaC, location-based features.
• C# reading ability, technical writing.
