They are seeking a US Defense Software Engineering Lead to lead a small, agile development team dedicated to building mission-critical capabilities for US national security customers.


Responsibilities

  • 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

Skills

  • 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

  • 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

  • Active Secret clearance preferred; TS/SCI is a plus
  • 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
