Staff Software Engineer – Core AI Platform (MCP & Agent Infrastructure)

JobsCloseBy Editorial Insights

Sumo Logic seeks a Staff Software Engineer for the Core AI Platform, focusing on MCP and Agent Infrastructure, to build a scalable, secure MCP-first platform powering Dojo AI agents. You’ll own the MCP server infra, federated context, and the agent-to-tool layer, architecting real-time context, fault-tolerant execution, and multi-tenant security. You’ll drive Slack and Teams integrations, lead architecture reviews, and mentor engineers. Requirements: 8+ years in large-scale distributed backends, MCP expertise, AWS-native stack, IaC, security, on-call ownership. This is full-time onsite in Redwood City with a base salary of $207k to $243k. Apply by tailoring your resume to MCP design, federation, tool invocation, observability, and production readiness, and be ready to discuss trade-offs and incident response, as well as collaboration across teams.

Staff Software Engineer – Core AI Platform (MCP & Agent Infrastructure)

As a Staff Software Engineer on the Core AI Platform team, you will lead the design and development of the foundational platform that powers Dojo AI agents at Sumo Logic. You will own the architecture and implementation of a robust, scalable MCP (Model Context Protocol)–based platform that enables AI agents to securely access context, invoke tools securely, and interact with enterprise systems in real time.

In this role, you will build and operate the core MCP server infrastructure, including frameworks for hosting first‑party MCP servers, federating with external and third‑party MCP servers, and orchestrating agent interactions across distributed environments. You will design systems that allow agents to reason over real‑time and historical context, manage conversation state and memory, and reliably execute tool calls with strong guarantees around fault tolerance, retries, idempotency, and isolation.

You will also architect the agent communication layer, enabling seamless integrations with systems such as Slack, Microsoft Teams, and other event‑driven communication platforms, allowing agents to be invoked from messages, threads, and workflows. Your work will ensure secure handling of credentials, webhooks, and streaming events while supporting multi‑tenant execution at enterprise scale.

A key part of your responsibility will be building deep observability and reliability into the platform—providing visibility into MCP interactions, agent decision paths, and tool executions; enabling monitoring, alerting, and debugging of non‑deterministic agent behavior; and enforcing rate limits, quotas, and backpressure to ensure platform stability.

Responsibilities

• Architect MCP-first platforms

• Drive technical leadership
• Lead architecture and design reviews across AI, platform, and product teams
• Mentor engineers and establish best practices for building AI infrastructure
• Operate at scale
• Continuously improve platform scalability, reliability, latency, and cost efficiency
• Own production readiness, incident response patterns, and operational excellence
