Fullstack engineer evolving memodio’s prescribed digital health app with Flutter and Node.js. Building accessible features and regulated medical software for older users worldwide.
About the role
- Backend Engineer developing scalable web services in Java and/or Scala for game clients. Collaborating with client engineers to ensure effective integration across platforms and support live game operations.
Responsibilities
- 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.
- **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
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
- А 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.
