Lead Software Architect, Rust

Lead Software Architect, RustWaltham, Massachusetts, United StatesAnduril 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 JobWe are looking for a Lead Software Architect to join our rapidly growing C2 Systems team in Waltham, MA. In this role, you will be responsible for defining the architectural direction of large-scale, real-time, mission-critical C2 software that powers Anduril's air and missile defense and battlespace awareness capabilities. You will lead the design of high-performance systems spanning tactical edge deployments to distributed backend infrastructure, make critical trade-offs between performance, modularity, and maintainability at scale, and mentor senior engineers across the C2 organization. This will require deep expertise in modern C++ and Rust, experience architecting numerics-heavy real-time systems, fluency with asynchronous/multithreaded programming (e.g., Tokio), and a strong grasp of the complex intersection of software and math — including state estimation, target tracking, optimization, and dynamic programming (MCP / Bellman equations). If you are someone who thrives on ambitious defense problems, enjoys troubleshooting real-world systems where issues could range from electromagnetics to faulty bit encodings to incorrect math assumptions, and wants to build software that is beyond a proof-of-concept — part of real tactical code deployed to the warfighter — then this role is for youWhat You'll DoDefine and drive the architectural vision for large-scale C2 software systems that ingest, fuse, and act on data from diverse sensors in real timeLead the design and implementation of performant, real-time, numerics-heavy algorithms in Rust and/or C++ at production scalePartner closely with research scientists to transition advanced algorithms (target tracking, state estimation, sensor-effector pairing, asset scheduling) from prototype into tactical, deployed codeMake high-leverage architectural trade-offs across performance, modularity, testability, and maintainability for mission-critical, edge-deployed systemsMentor and technically lead senior engineers, setting coding standards, review processes, and CI/CD best practices across the teamEngage directly with customers (DoD agencies, Army, Air Force, MDA, SCO) to ensure successful outcomes for mission-critical needsTroubleshoot complex, real-world system issues spanning software, math assumptions, sensor behavior, and networkingContribute to all phases of the software development lifecycle including prototyping, modeling & simulation, field testing, and deploymentHelp shape hiring and technical growth of the broader C2 organization as it hyper scalesRequired Qualifications10+ years of software engineering experience with a Bachelor's degree (or equivalent) in Computer Science, Applied/Computational Mathematics, Electrical Engineering, Aerospace Engineering, Controls/Dynamical Systems, Statistics, or related fieldExpert-level proficiency in modern C++ and/or Rust, including asynchronous and multithreaded programming (e.g., Tokio for Rust)Proven experience architecting large-scale, production-grade codebases in real-time or high-performance environmentsDeep experience writing performant, real-time software with numerics-heavy algorithmsStrong foundation in applied mathematics: probability theory, linear algebra, optimization, differential equations (ODEs), and statisticsExperience with CI/CD, unit testing, git version control, and microservicesEligible to obtain and maintain an active U.S. Secret security clearancePreferred QualificationsM.S. or Ph.D. in a technical field (dual academic background in software + math highly valued)Domain expertise in target tracking, state estimation, Kalman filters, sensor fusion, or signal processingPrior DoD program experience (Army, Air Force, MDA, SCO, Navy)Experience with GPU / CUDA kernel developmentWe 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.US Salary Range$253,000 - $336,000 USDThe salary range for this role is an estimate based on a wide range of compensation factors, inclusive of base salary only.
