Mattermost is seeking a fully remote US Defense Software Engineering Lead anywhere in the United States to lead a small, agile development team dedicated to building mission-critical capabilities on top of the Mattermost platform for US national security customers. You will sit at the intersection of product delivery, customer partnership, and engineering excellence — translating the complex operational needs of defense users into software that works reliably in the most demanding environments on earth.

This is not a role for a detached manager. You will be hands-on, customer-facing, and deeply invested in the US national security mission. You'll collaborate closely with customers and forward-deployed engineers to gather requirements from the field, then translate those requirements back to your product engineering team to drive delivery. You will own the full stack — from architecture decisions to shipping — and set the bar for quality, velocity, and accountability.

Do you thrive in high-stakes environments where the software you build genuinely matters? Are you energized by leading focused, high caliber engineers and working directly alongside the customers who depend on your work? Do you embrace AI as a force-multiplier for engineering productivity? If so, we want to hear from you.

What You'll Do

• Work remotely and autonomously within a distributed, global team — you'll own your work and stay closely connected across time zones.
• Lead, mentor, and grow a small, agile full-stack engineering team focused on delivering product capabilities tailored to US national security customers on top of the Mattermost platform.
• Own the end-to-end engineering delivery lifecycle: requirements, architecture, development, testing, and release.
• Collaborate with customers and forward-deployed engineers to capture requirements directly from the field and translate them into well-scoped, executable engineering work for the core team.
• Interface directly and professionally with US national security customers — building trust, managing expectations, and communicating technical trade-offs clearly to non-engineers.
• Partner with product and design stakeholders to define roadmaps that balance customer needs, platform constraints, and strategic priorities.
• Maintain a full-stack technical perspective, contributing to architecture decisions across frontend, backend, and infrastructure layers.
• Establish and uphold engineering standards for code quality, security, testing, and documentation appropriate for a defense-grade software environment.
• Champion the adoption of AI-powered development tools (e.g., Cursor, Claude, GitHub Copilot) across the team to accelerate velocity and automate repetitive engineering tasks.
• Actively manage team health: conduct regular 1:1s, identify growth opportunities, address blockers, and foster a culture of ownership and psychological safety.
• Participate in technical hiring and onboarding to expand the team as the mission scales.
• Provide accurate effort estimates, status updates, and risk assessments to leadership and program stakeholders on a regular cadence.

What We're Looking For

Required Qualifications

• BS in Computer Science, Computer Engineering, or related field/experience.
• 5+ years of professional software engineering experience, including 2+ years in an engineering management or tech lead role.
• Proven full-stack product development experience — comfortable owning decisions across frontend (e.g., React) and backend (e.g., Go, Node.js) layers.
• Demonstrated ability to lead small, agile teams in a fast-paced, high-accountability environment.
• Experience interfacing directly with customers or end users in a technical capacity — able to listen, synthesize, and communicate complex technical concepts clearly to non-engineers.
• Strong written and verbal communication skills for collaborating across distributed, remote teams and presenting to senior stakeholders.
• Proficiency with AI/LLM development tools (e.g., Cursor, GitHub Copilot, Claude) with a genuine commitment to integrating them into daily engineering workflows.
• US citizenship is required. This role may require the ability to obtain and maintain a US government security clearance in the future. Applicants must reside in the United States.
• Applicants must meet eligibility requirements for access to export-controlled information as defined by US export control laws, including EAR and ITAR.
• Strong personal alignment with the US national security mission and the communities it serves.
• Travel 1-2 weeks per quarter.

Clearance Requirements

• Must be eligible to obtain and maintain a U.S. security clearance
• Active Secret clearance preferred; TS/SCI is a plus

Preferred Qualifications

• Previous experience working with or for the US Department of Defense (DoD), defense contractors, or the intelligence community.
• Familiarity with defense-specific software environments, including DDIL (Disconnected, Denied, Disrupted, Intermittent, and Limited) network conditions.
• Experience working fully remotely with distributed, global teams.
• Background building secure, compliant software for government or regulated industries.
• Experience hiring, growing, and retaining exceptional engineering talent in a remote environment.
• Prior work in open-source projects or platform-level software development.
• Contributions to Mattermost or similar collaboration/communications platforms.

• Take ownership of outcomes, not just code
• Are comfortable operating in classified environments
• Thrive when solving complex problems with limited information

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.

You will help build and deploy systems such as:

• 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

We are looking for engineers who are excited about experimenting with AI capabilities while maintaining mission-grade security and reliability.

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
