Senior Agentic Engineer - Java Backend & DevOps

Goodgame Studios

1d • Remote

About The Position

We are seeking a Senior Agentic Engineer with a strong background in Java backend development and DevOps. This role is for an individual who has practical experience running agentic workflows in production, including parallel agents, custom subagents, skills, planning loops, and review gates. You will apply this expertise to backend systems that support millions of players in real-time, focusing on always-on, low-latency, and unpredictable load scenarios where performance is critical. You will join Goodgame Studios, a company known for its self-published MMO strategy titles, with a large player base and significant lifetime revenue, and part of the Stillfront Group.

Requirements

• 6+ years of backend Java experience, expert level.
• Proficiency in distributed systems, concurrency, GC tuning, and SQL optimization.
• Deep knowledge of AWS and cloud-native stack (K8s, Docker, Terraform).
• A real agentic coding practice, with concrete experience in structuring prompts and context for long-running tasks, managing multi-agent setups, and building with custom tools/skills.
• Ability to review agent-generated code without becoming a bottleneck.
• Strong analytical decomposition skills to turn fuzzy product asks into precise constraints for humans and agents.
• Architectural judgment to design clean, resilient systems.
• Highly proficient in English.
• Seeking full-time remote roles within Germany (valid German visa required) or Freelance opportunities within the German timezone (CET/CEST).

Nice To Haves

• Gaming backend experience (matchmaking, inventories, leaderboards, economy services).
• Experience with event-driven architectures (Kafka, Kinesis, SQS/SNS).
• Experience with real-time telemetry or anti-cheat systems.
• Published or shared work on agentic workflows (blog posts, OSS subagents/skills, open-sourced internal tooling).

Responsibilities

• Own backend services end-to-end: architecture, implementation, infrastructure, deployment, production, and scaling.
• Operate at 10–20× the throughput of a classical engineer by orchestrating agents rather than typing every line yourself, acting as architect and reviewer.
• Design and operate high-throughput, low-latency Java services (JDK 17+) on AWS, K8s, Terraform, and ArgoCD.
• Build resilient distributed components and tune memory, concurrency, and GC for real production workloads.
• Architect MySQL and Redis layers handling millions of player rows.
• Own CI/CD, observability, and on-call for systems you ship.
• Run an agentic workflow that holds up under code review, including precise specs, tight feedback loops, generated tests, validation gates, and applying your judgment on architecture, security, and performance.
• Help define how the rest of the engineering organization adopts agentic practices, including tooling, review standards, and defining 'done' when an agent writes a significant portion of the code.

Benefits

• High autonomy.
• Remote work within the German time zone.
• Engineering-first culture.
• Genuinely interesting technical surface area: Java, MySQL, Redis, AWS, distributed systems, and agentic practices.
• Opportunity to collaborate closely with a team of dedicated professionals.
• Work on systems players interact with every minute at a large scale.
• Help set the standard for agentic engineering in a production environment.
