Role Description We are looking for an engineer who architects the service, deploys it, monitors it in production, responds when it breaks, and improves it after every incident. 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. Qualifications - 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. Requirements - 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. Benefits - Strong and enthusiastic team – you will have the opportunity for knowledge sharing, learning, and professional self-development. - Interesting and challenging tasks – solve diverse and challenging issues, communicate with people within the company as well as with our partners. - Convenient working conditions – remote work, the opportunity to build your own working day with flexible working hours. - A chance to work in a highly professional and dynamic team working with a wide range of International Game Production projects, attractive remuneration package, and opportunities to develop professionally.

• Design, develop, and maintain backend services, APIs, and business logic • Collaborate with front-end engineers, product partners, and other stakeholders • Participate in roadmap execution that balances feature delivery with backend health • Provide technical guidance to junior developers • Participate in code reviews to ensure solutions align with established engineering standards

• Design and build the control plane API: the interface that range orchestration and scenario systems use to drive the internet simulation platform, with strong attention to idempotency, consistent error semantics, and the operational patterns that make a platform API pleasant to build on. • Own the event-driven orchestration layer that coordinates multi-step operations across the platform's subsystems, ensuring that standing up a new range, registering a persona, incorporating a SaaS application, or updating topology propagates correctly and completely across all components. • Build and maintain the platform's persistent storage layer, providing reliable, well-abstracted storage primitives for the services and subsystems that depend on it, across file, object, and container storage as requirements evolve. • Own the deployment model for the internet simulation platform itself: the Kubernetes operators or controllers that manage platform lifecycle, the upgrade and rollout strategy for a service that cannot afford downtime, and the configuration model for integrating new ranges. • Define and own the state model for the platform, what is authoritative where, how components recover from partial failures, and how the platform converges to a correct state after disruption. • Collaborate with the network simulation tech lead on the in-range proxy agent architecture, owning the infrastructure side of that interface: agent deployment, connectivity management, and the handoff model when an agent loses contact with the control plane. • Partner with the SRE team on the operational model for a new platform service, establishing runbooks, incident response procedures, and the observability instrumentation that makes the platform debuggable in production. • Contribute to cross-cutting concerns including configuration management, secrets handling, and the security posture of the control plane.

• Design, develop, and maintain core services for cybersecurity range simulation, focusing on scalability, performance, and fault tolerance. • Lead end-to-end technical projects, from requirements gathering and architecture design to deployment, while setting clear goals and priorities. • Mentor and support engineers on the team, promoting a collaborative culture and guiding them in coding best practices, testing, and architectural design. • Collaborate cross-functionally with Product Managers and UX Designers to translate requirements into technically sound, user-centered solutions. • Conduct code reviews and provide constructive feedback to ensure code quality, performance, and adherence to company standards. • Implement robust monitoring and alerting strategies to maintain high uptime and quick response to potential system issues. • Ensure services meet security and compliance standards by integrating appropriate controls into the development lifecycle. • Contribute to documentation that details technical architecture, system design, and best practices to ensure knowledge sharing and team alignment.
