Resumo da oferta

Genesys is seeking a Principal Engineer to design, build, and operate the MCP, A2A, and agentic workflow systems. This hands-on role focuses on deep technical work, including the MCP server/client infrastructure, the A2A communication layer, and the orchestration runtime that powers agentic workflows.

You will solve the hardest problems in the stack, guide architecture decisions, and collaborate with engineers across the stack.

Qualificações

• 12+ years of professional software engineering experience, still writing code.
• Deep hands-on expertise with MCP: designed and shipped MCP servers and clients.
• Deep hands-on expertise with A2A or equivalent multi-agent communication patterns.
• Proficiency in Java and/or TypeScript/Node.
• Experience building evaluation and observability for non-deterministic systems.

Responsabilidades

• Design and build Genesys MCP infrastructure: servers, clients, tool and resource schemas, transports, auth and scoping, versioning, and the internal MCP registry.
• Build the A2A layer: agent discovery, capability advertisement, task delegation and handoff, message contracts, trust boundaries, and failure semantics between agents.
• Build the agentic workflow runtime: planning and tool-call loops, state and context management, memory, human-in-the-loop checkpoints, retries, and termination conditions.
• Take the hardest problems in the stack end to end, from prototype through production.
• Build the evaluation and observability tooling for agent systems: tracing across agent hops and tool calls, eval harnesses, regression gates, cost and latency instrumentation.
• Engineer the security of agent systems: tool sandboxing, least-privilege tool access, prompt-injection and tool-abuse defenses
• Debug and resolve the production failures nobody else can, across non-deterministic multi-agent paths
• Make build-vs-buy calls on agent infrastructure: MCP gateways, agent runtimes, orchestration frameworks, eval tooling
• Work directly with the engineers building on this stack, through code review, design review, and pairing
