Software Engineering salaries →Harmattan AI is a next-generation defense prime building autonomous and scalable defense systems. Following the close of a $200M Series B, valuing the company at $1.4 billion, we are expanding our teams and capabilities to deliver mission-critical systems to allied forces.
Our work is guided by clear values: building technologies with real-world impact, pursuing excellence in everything we do, setting ambitious goals, and taking on the hardest technical challenges. We operate in a demanding environment where rigor, ownership, and execution are expected.
As a Software Engineer, Mission Execution, you'll build the software backbone that carries mission plans from the planner to the field. You'll own the infrastructure that executes missions on autonomous robots and multi-agent systems. You'll work closely with the Mission Planning engineer, simulation engineers and product teams to make sure our systems are reliable, testable, and predictable in live operations.
Design and build the mission execution infrastructure that turns planned missions into reliable, real-time behavior across fleets of autonomous systems.
Develop scalable backend services and APIs for mission guidance, orchestration, agents communication, and execution.
Set and defend a high quality bar: CI/CD pipelines, testing, code review standards, observability, and release discipline.
Write production-grade C++ and Python that runs in real-time and resource-constrained environments.
Partner with Mission Planning, and product teams to ensure algorithms are integrated cleanly, tested thoroughly, and deployable in the field.
Analyze logs and telemetry from tests and live operations to find failure modes and drive systemic fixes.
Education: M.S. or Ph.D. in Computer Science, Robotics, Aerospace Engineering, or a related field, or equivalent practical experience.
Technical skills: Strong coding in C++ and Python, with solid software engineering fundamentals (system design, concurrency, testing, debugging).
Experience building and shipping production software: Ideally with distributed or real-time systems.
Nice to have: Experience in robotics, embedded software, or video game development (game engines, simulation, deterministic replay, tooling). Experience in aerospace or defense. Familiarity with simulation frameworks.
Mindset: Strong communication skills, Rigor, ownership, and a strong instinct for quality.
Commitment: 100% dedication to Harmattan AI's mission, vision, and ambitious growth plans, ready to go the extra mile to ensure operational excellence.
We look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI.
