Mission-Critical Software Engineer: Autonomous Systems

Signal Processing Engineer (RF Processing & Analytics); Paris; On-site; EUR 90,000 - 130,000; Full time

Job summary

Harmattan AI is seeking a Software Engineer, Mission Execution, to build the real-time mission execution backbone for autonomous robots and multi-agent systems. You will own infrastructure that translates mission plans into live behavior across fleets and work with planning, simulation, and product teams.

The role emphasizes reliability, testability, and deployable software in resource-constrained environments, requiring C++ and Python, strong systems knowledge, and a drive for quality in

Qualifications

• MS or PhD in CS/Robotics/Aerospace or related field, or equivalent practical experience.
• Strong C++ and Python coding with solid software engineering fundamentals (system design, concurrency, testing, debugging).
• Experience shipping production software, ideally with distributed or real-time systems.
• Nice to have: robotics, embedded software, or game engine experience (game engines, simulation, deterministic replay, tooling).
• Experience in aerospace or defense.
• Familiarity with simulation frameworks.
• Mindset: strong communication, rigor, ownership, and quality.
• Commitment: 100% dedication to Harmattan AI's mission and growth plans.

Responsibilities

• 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.
