Forward Deployed Engineer

What You’ll Do

Forward Deployed Engineers operate at the intersection of engineering, operations, and mission execution.

• Work directly with defense and intelligence organizations to understand operational problems
• Deploy and integrate Mattermost in classified and mission-critical environments
• Build plugins, integrations, and automations that enable operational workflows
• Prototype new capabilities quickly and iterate based on operator feedback
• Debug complex systems operating in constrained environments
• Help shape the evolution of the Mattermost platform based on mission needs

You will move between writing code, deploying infrastructure, and working directly with operators, often within the same week. Travel is typically approximately one week per month onsite with customers.

AI-Forward Engineering

Mattermost Federal is aggressively adopting AI-enabled workflows across mission operations. FDEs will be among the first engineers deploying and operationalizing AI capabilities in secure environments.

• AI agents that summarize operational channels and generate SITREPs
• AI-assisted mission timelines and decision logs
• Knowledge retrieval across operational history
• AI tools that help operators understand fast-moving mission data

What We Look For

• Strong engineering ability (Go, Python, TypeScript, or similar)
• Comfort working across the full stack from infrastructure to applications
• Ability to solve open-ended technical problems
• Strong communication skills with both engineers and operators
• Willingness to travel ~1 week per month

Ideal Background

• Experience working with DoD, IC, or national security organizations
• Experience deploying systems in secure or classified environments
• Familiarity with Kubernetes, distributed systems, and APIs
• Experience building integrations or operational tooling

Security Requirements

• U.S. Citizenship required
• Active TS/SCI clearance preferred or ability to obtain one
• Applicants must meet eligibility requirements for access to export-controlled information as defined by U.S. export control laws, including EAR and ITAR.
