C2 Software Frontend Engineer

Harmattan AI

ABOUT US 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. ABOUT THE ROLE We are looking for a dedicated Software Engineer to join our C2 Core team in Paris to build the "nervous system" of our new tactical Command and Control (C2) application. You will enter a highly technical, mission-critical environment where low latency, fault tolerance, and secure data handling are paramount. You will be responsible for the core architecture that ensures real-time telemetry, heavy video streams, and mission commands flow seamlessly between our robot fleet and internal C2 components, such as the Common Operational Picture (COP) and Mission Planner. This system is designed to run on ruggedized, resource-constrained tactical PCs in the field, often under degraded network conditions. RESPONSIBILITIES * Robot-to-C2 Communications Gateway: Design and implement ingestion pipelines for high-frequency telemetry and video streams from multiple robots simultaneously. * Internal Messaging & IPC: Build the inter-process communication (IPC) or local pub/sub systems to route sensor data, user commands, and mission plans between the HMI and the robot fleet. * Resource Optimisation: Ensure the backend runs efficiently on local tactical PCs, managing CPU and memory footprints to prevent interference with UI or planning algorithms. * Fault Tolerance: Architect state machines capable of handling the chaos of tactical environments, including frequent network drops and packet loss, without corrupting the Common Operational Picture. * Cross-Functional Collaboration: Partner with Mission Planning algorithm designers, HMI frontend developers, and UX designers to deliver a cohesive product . CANDIDATE REQUIREMENTS * Educational Background: B.S. or M.Sc. in Computer Science, Software Engineering, or a related field * Experience shipping production-grade applications with complex data visualization and real-time UI requirements.   Technical Skills: * Strong command of system-level languages such as C++, Rust, or Go. * Deep expertise in Real-Time Networking (UDP, TCP, WebRTC, gRPC, DDS, or custom binary protocols). * Expertise in Systems Architecture & IPC, specifically using bounded ring buffers or zero-copy shared memory for high-concurrency pipelines. * Proficiency in profiling and capping resource footprints using tools like perf or cgroups. * Soft Skills: * Ownership & Mission-Driven: A high degree of commitment to Harmattan AI’s mission and the ability to thrive in a fast-paced startup environment. * Communication: Ability to mediate technical trade-offs between hardware, algorithm, and frontend teams. We look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI.

We operate in a demanding environment where rigor, ownership, and execution are expected. ABOUT THE ROLE We are looking for a Software Engineer to join our Geometric Scene Understanding team in Paris. In this role, you will bridge the gap between complex mathematical research and mission-critical production software. While our Computer Vision (CV) engineers design the core algorithms for 3D reconstruction—such as SfM, SLAM, and Neural Radiance Fields—you will be responsible for transforming these computationally heavy prototypes into high-performance, real-time engines capable of running on resource-constrained tactical hardware. You will be the architect of the pipeline that ingests live drone telemetry and video to output a real-time 3D rendering of the battlefield, providing a decisive edge for the Common Operational Picture (COP).   RESPONSIBILITIES * High-Performance Pipeline Construction: Architect and build the software pipeline to ingest, decode, and perfectly synchronise multi-drone video streams and telemetry data. * Hardware Acceleration: Profile CV algorithms and rewrite bottlenecks using GPU acceleration (CUDA, Vulkan, or TensorRT) and CPU multi-threading to achieve near real-time 3D reconstruction. * Spatial Data Management: Implement efficient 3D data structures, such as Octrees or Voxel grids, to store, compress, and stream point clouds or meshes without compromising system memory. * Prototype-to-Production Translation: Collaborate with CV engineers to translate Python/PyTorch prototypes into production-grade C++ code that can run for hours without heap fragmentation or leaks. * Hardware-in-the-Loop (HITL) Testing: Deploy builds to physical tactical PCs and monitor real-world performance, including thermal throttling and GPU utilisation during live drone operations. Candidate Requirements * Educational Background: A BS or MS in Computer Science, Computer Engineering, or a closely related field. Strong foundational knowledge of Linear Algebra, 3D Geometry, and Computer Architecture is critical. * Technical Mastery: Absolute mastery of C++ and low-level memory management. Deep expertise in GPU programming (writing custom CUDA kernels) is required. * Proven Experience: * Minimum of 5-6 years of experience for senior-level candidates. * Track record of shipping high-performance software in production, such as game engines, rendering pipelines, or autonomous vehicle perception stacks. * Experience optimising complex algorithms for edge devices or embedded systems under strict real-time constraints. * Systems Engineering: Ability to design ingestion buffers for asynchronous, high-bandwidth data streams (e.g., video at 30fps and telemetry at 100fps) ensuring temporal alignment. * Adaptability & Mission Focus: Thrives in a fast-paced startup environment and is 100% dedicated to building ethical defensce technologies that bring a strategic edge to allied nations. * Communication: Excellent verbal and written communication skills to lead syncs between CV research teams and C2 backend modules We look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI.
