We are looking for a Backend Engineer with strong Java and C++ experience to work on backend systems supporting game functionality and the client/server interface.

This role sits at the intersection of backend services and game client integration, requiring someone who understands not only how to build reliable server-side systems, but also how those systems are consumed by game clients. You will work across the MCP backend, client/server interface, and JSON export processes, with a strong focus on performance, efficiency, security, and correctness.

The ideal candidate is comfortable working within real-world performance constraints and understands how techniques such as throttling, batching, caching, and mocking API calls can reduce unnecessary database writes, minimize latency, and keep systems responsive at scale.

Because these systems handle sensitive player data, we are looking for an engineer with sound technical judgment, disciplined testing practices, and exceptional attention to detail.

Key Responsibilities:

Service Design & Architecture

• Design and build scalable, resilient web services in Java and/or Scala that support game client needs across PC, console, and mobile

• Own the data model — choose the right store (MongoDB for flexible document storage, DynamoDB for key-value at scale, Redis for caching and session state) and justify it

• Design REST APIs that game clients actually integrate well against — clear contracts, versioned, documented, forgiving of client-side variation

• Architect for the load profile of a live game: average load, launch spikes, event peaks, and graceful degradation when upstream dependencies fail

• Define and enforce service boundaries — knows where one service ends and another begins, and why

AWS Infrastructure & Deployment

• Build and maintain AWS infrastructure using IaC tooling (CDK, Terraform, or CloudFormation — confirm what's in use on the engagement)

• Own the deployment pipeline for services they build: CI/CD configuration, environment promotion, rollback capability

• Right-size AWS resources for cost and performance — does not default to over-provisioning and does not leave obvious cost inefficiencies

• Familiar with the AWS services relevant to game backends: EC2, ECS/EKS, Lambda (where appropriate), API Gateway, ElastiCache, SQS/SNS, CloudWatch, S3

• Understands the network and security posture of services exposed to game clients — VPC design, security groups, IAM least privilege, secrets management

Live Operation & Observability

• Instruments every service for production readiness: structured logging, metrics, distributed tracing, health checks, and alerting before it goes live — not after the first incident

• Monitors services in production: reads dashboards, interprets anomalies, distinguishes noise from signal

• Responds to production incidents in services they own — has on-call responsibilities commensurate with service criticality

• Writes post-mortems and follows through on structural improvements so the same failure mode does not recur

• Understands the difference between a symptom and a root cause — does not fix symptoms

Cross-Platform Client Integration

• Works directly with game client engineers (PC, console, mobile) to define integration contracts, review client-side usage patterns, and debug integration issues

• Understands the constraints of each platform environment: console certification requirements around network usage, mobile data sensitivity, PC permissiveness — and designs service interfaces accordingly

• Owns the integration surface: API documentation that is correct, versioned, and kept up to date as the service evolves

• Participates in client-facing technical reviews where backend service design is on the table

Quality & Engineering Standards

• Writes unit and integration tests as a first-class output — not an afterthought

• Code reviews: gives specific, actionable feedback and receives it without defensiveness

• Maintains service documentation: architecture decisions, operational runbooks, known limitations, dependency map

• Raises technical debt explicitly — names it, quantifies its cost, and proposes a remediation path

Requirements

• 5+ years of professional software engineering experience, with significant experience developing backend/server-side systems.
• At least 2 years of professional Java experience, including production backend development.
• At least 2 years of professional C++ experience, ideally in game development or another performance-sensitive environment.
• Demonstrated experience working across the client/server interface, rather than purely backend development.
• Experience developing and integrating REST APIs and working with JSON-based data exchange.
• Experience with JSON export/data serialization processes.
• Strong understanding of performance optimization techniques including throttling, batching, caching, request optimization, and API mocking.
• Experience designing systems that minimize unnecessary database operations and network calls.

Preferred

• Experience designing services that handle launch-day spikes: horizontal scaling patterns, queue-based load levelling, circuit breakers

• Familiarity with platform-specific SDK constraints: PlayStation Network, Xbox Live, Nintendo NSO, or Apple/Google mobile — understanding what the platform restricts and what it requires from the backend

• Kafka or SQS/SNS for event-driven service communication

• Kubernetes (EKS) cluster operations experience

• Security-conscious engineering: OAuth/OIDC, rate limiting, input validation, OWASP awareness at service design level
