THE OPPORTUNITY:
As a Senior Backend Engineer at Eleventh Hour Games, you will play a key role in shaping the technical direction of EHG. You will own core service architecture and scalability for gameplay-critical features like game server hosting, matchmaking, inventories/economy, and telemetry all while ensuring reliability under peak traffic and enabling rapid iteration by the broader engineering team. The ideal candidate thrives with complex problem-solving and brings strong communication skills to drive collaboration across a fully remote, global team.
WHAT YOU'LL DO:- Own the architecture of core backend systems for Last Epoch: gameplay services, state/inventory services, player progression, and economy-related workflows.
- Design and implement scalable APIs and event-driven pipelines.
- Build for high availability and performance on Azure, including data storage, caching, queues, and background processing.
- Establish engineering standards for C# backend development: patterns, performance practices, resilience, observability, and security.
- Drive reliability practices: idempotency, consistency models, graceful degradation, incident response, and chaos-minded fault handling.
- Partner with game design and product to translate gameplay requirements into robust technical solutions.
- Improve code and feature velocity through reviews, architecture docs, and reusable frameworks/libraries.
- Contribute to CI/CD and operational readiness: automated tests, deployments, monitoring/alerting, and run books.
RESPONSIBILITIES:
- Security & Compliance: Apply secure-by-default practices (authn/authz, proper secret handling, least privilege, and threat modeling for exposed endpoints).
- System Design & Ownership: Define service boundaries, contracts, and data models; make key tradeoffs for cost/latency/consistency.
- Scalability & Reliability: Implement durable messaging patterns, backpressure strategies, and fault-tolerant workflows.
- Performance Engineering: Optimize hot paths in C# services and reduce latency through caching, batching, and efficient data access.
- Observability: Ensure logs/metrics/traces support debugging and live operations; set SLOs/SLAs where appropriate.
- On-Call: Diagnose and lead resolution of complex service, infrastructure, and live-ops issues; participation in an on-call rotation (Pager Duty)
QUALIFICATIONS:
- 5+ years building and supporting online services with SLA requirements
- Strong backend engineering experience writing high performance C#
- Production experience on Azure, with specific focus on AKS and CosmosDB
- Demonstrated experience building distributed systems and event-driven architectures.
- Deep understanding of data consistency, idempotency, retries, and failure modes.
- Strong hands-on skills in API design, performance tuning, and operational excellence.
- Experience designing systems that support real-time or near-real-time gameplay loops (sessions, lobbies, inventory updates, or matchmaking/server instance lifecycles).
- Background in systems design, with ability to build maintainable, scalable solutions
- Experience with mentoring engineers, code reviews, and setting technical standards
- Excellent cross-discipline collaboration and communication skills
PREFERENCES:
- 2+ years experience working in a game studio
