About The RoleSenior Software Engineer, Air & Missile Defense

Broomfield, Colorado, United States; Fort Collins, Colorado, United States

Anduril Industries is a defense technology company with a mission to transform U.S. and allied military capabilities with advanced technology. By bringing the expertise, technology, and business model of the 21st century's most innovative companies to the defense industry, Anduril is changing how military systems are designed, built and sold. Anduril's family of systems is powered by Lattice OS, an AI-powered operating system that turns thousands of data streams into a realtime, 3D command and control center. As the world enters an era of strategic competition, Anduril is committed to bringing cutting-edge autonomy, AI, computer vision, sensor fusion, and networking technology to the military in months, not years.

About The Team

Anduril's Software Engineers excel at developing state-of-the-art algorithms and software that solve scientific problems with real-world applications. Working in small innovative teams, our software engineers build solutions that make a difference. Our research endeavors don't end once we've written a journal or conference paper describing our technology; rather, our work is complete when our technology has been deployed in mission-critical systems and our customers within government and industry are successful. As science fiction writer Arthur Clarke wrote, 'Any sufficiently advanced technology is indistinguishable from magic.' Anduril is seeking talented 'magicians' — experienced engineers who lead by example, mentor others, and stay deeply hands-on in the code — to join in our mission to expand the boundary of what's possible.

What You Will Do

• Help shape the technical direction of a small, high-impact team while remaining deeply hands-on in design, implementation, and code review
• Mentor and uplevel junior and mid-level engineers through pair programming, code reviews, technical guidance, and architectural discussions
• Lead by example by writing production-quality C++ and Python that powers mission-critical systems, while setting the bar for engineering excellence (CI/CD, unit testing, large-codebase collaboration, git workflows)
• Prototype state-of-the‑art software solutions in an agile development environment and guide the team through the path from prototype to deployed, tactical implementation
• Implement high‑performance software spanning the spectrum from tactical systems to web applications
• Use high‑fidelity modeling and simulation environments, innovative analysis tools, and sound analysis techniques to quantify the benefit of our technology
• Drive technical interchange meetings, sprint planning, and customer engagements to ensure successful outcomes for mission‑critical needs
• Own all aspects of the software development lifecycle, helping the team navigate ambiguity and complex technical trade‑offs
• Communicate complex technical concepts clearly to colleagues, customers, and non‑technical stakeholders

Required Qualifications

• 8+ years of software engineering experience and a Bachelor's degree or equivalent education/work experience
• Demonstrated experience mentoring junior engineers and providing technical leadership on a team, while continuing to contribute as a hands‑on individual contributor
• Experience supporting and navigating large, complex codebases as part of a collaborative team
• Strong proficiency in C/C++ and Python
• Big data/NoSQL/database technologies
• Software engineering: software design, algorithm implementation, and software analysis, testing, and optimization
• Machine learning: supervised and unsupervised learning, clustering, and classification
• Applied mathematics: differential equations, linear algebra, optimization, statistics, and random processes
• Engineering: controls, estimation theory, and digital signal processing
• Eligible to obtain and maintain an active U.S. Top Secret SCI security clearance

Preferred Qualifications

• Experience leading small teams or technical workstreams while remaining a top individual contributor
• Track record of growing engineers through mentorship, code review culture, and technical coaching
• Experience with asynchronous programming, parallel programming, and GPU programming
• Prior experience deploying software to real‑world tactical/edge environments

We request transcripts as part of the early application process to understand your academic background and how your coursework supports the skills deemed critical for the role. Transcripts help us assess your technical and analytical abilities, complementing our interview process in which we also evaluate practical experience and cultural fit. If you choose not to share your transcripts, you will need to provide detailed information regarding your academic performance in relevant courses, including projects and coursework specifics, to ensure we evaluate your academic accomplishments properly. If you do provide academic transcripts, feel free to redact non‑technical information (e.g., student ID, dates, non‑technical coursework, etc.). Unofficial transcripts obtained online acceptable for this assessment.
