This is not a server-side feature developer who hands services to an ops team once they ship. It is an engineer who architects the service, deploys it, monitors it in production, responds when it breaks, and improves it after every incident.

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

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

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

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

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 backend/server-side engineering experience with at least 3 years working on services at live production scale

Java at a professional shipping level - not just familiarity. Has designed, built, and operated Java services in production.

AWS hands-on ownership - has provisioned, deployed, monitored, and debugged AWS infrastructure, not just used managed services provisioned by someone else

Polyglot data store fluency: has made deliberate choices between MongoDB, DynamoDB, and Redis for different use cases - not defaulted to one store for everything

REST API design with real client integration experience - PC, console, or mobile clients consuming services they built

End-to-end ownership mindset: has been on-call for services they wrote. Has written a post-mortem. Has shipped the fix.

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
