This fast-growing stealth defense technology startup is building an AI-native platform designed to automate complex operational and administrative workflows for mission-critical military organizations. By combining organizational data, knowledge graphs, LLM-powered agents, and workflow automation, the company is helping users replace highly manual processes with intelligent, scalable systems.


Backed by $2.5M+ in pre-seed funding from leading enterprise software and defense-tech investors, the company is already deployed with multiple Department of Defense customers and has approximately $270K in ARR, with significant growth expected as additional contracts launch. The team was also recently selected for a 7-figure Air Force R&D contract. This is an opportunity to join a small founding team at a key inflection point, take meaningful ownership of the product, and help shape both the technology and engineering culture as the company scales.


Responsibilities

  • Own end-to-end full-stack development of the core platform
  • Build customer-facing features, knowledge graphs, AI agent workflows, and internal platform capabilities
  • Develop across the frontend and backend, primarily using TypeScript
  • Translate customer and operational needs directly into production-ready features
  • Support customer launches and rapidly iterate based on real-world feedback
  • Build tools that allow customers to configure and manage their own AI agents and workflows
  • Integrate LLMs and AI orchestration systems into production applications
  • Develop and maintain scalable APIs, databases, and cloud infrastructure
  • Collaborate directly with founders and engineers on product direction, technical architecture, and feature prioritization
  • Participate in occasional customer visits to military installations to better understand users and operational workflows


Qualifications

  • 3–5 years of professional full-stack software engineering experience
  • Experience shipping production software end-to-end in a fast-paced startup or similarly high-ownership environment
  • Early-stage startup experience, ideally Seed or Series A
  • Strong full-stack engineering foundation across frontend, backend, databases, and infrastructure
  • Experience with TypeScript, Python, Next.js, Express, PostgreSQL, or similar technologies
  • Experience deploying and operating applications on AWS or another major cloud provider
  • Experience integrating LLMs, AI agents, or AI-powered workflows into production applications is a plus
  • Technical degree in Computer Science, Mathematics, Physics, Engineering, or a related field preferred
  • Strong product mindset with the ability to translate customer problems into scalable technical solutions
  • Comfortable working directly with customers and incorporating feedback into product development
  • Collaborative, low-ego approach with strong communication and problem-solving skills
  • Comfortable working in a fast-moving, ambiguous startup environment with significant ownership
  • U.S. citizenship required due to security clearance eligibility requirements
  • Able to work in person 5 days per week in downtown San Francisco
  • Open to occasional travel, approximately once per month
  • Military or defense-tech experience is a plus


Benefits

  • Competitive salary of $160K–$210K
  • 0.5%–1.5% equity
  • Equity currently priced at pre-seed levels ahead of an anticipated Seed round
  • Backed by $2.5M+ in pre-seed funding
  • Opportunity to join a small founding team with significant ownership and autonomy
  • Work directly with founders and early engineering team members
  • Shape the technical architecture, product direction, and engineering culture
  • Build technology used in real-world, mission-critical environments
  • Direct exposure to customers and the problems you're solving
  • Opportunity for meaningful career growth as the company scales
  • Relocation support may be available for candidates moving to San Francisco
