Autonomous defense systems and C2 platforms
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 Validation Engineer, you will play a critical role in validating the performance, reliability, and operational readiness of our autonomous defense systems. You will lead test campaigns on our own systems to inform internal development and maintain a competitive edge.
Validation strategy & test design: Define what "validated" means for a system, design the test plans and scenarios that will prove it, and decide what to measure and how to judge pass/fail.
Build the validation toolkit: Starting from the design phase of the new platform, create the procedures, tooling and test methods, software and hardware, that its validation will depend on.
Run campaigns & analyse results: Plan and lead test campaigns (in the field and using our simulation/bench tools), then analyse the data rigorously to separate real issues from noise and quantify performance.
Close the loop with engineering: Report defects, anomalies and their frequency clearly, and work with the design teams to drive fixes and product maturity.
Support the wider group: Occasionally contribute to validation trials for the rest of the teams, bringing back data and lessons learned.
Engineering degree (or equivalent experience) in aerospace, mechatronics, electronics, robotics, or a related field.
10+ years of experience in validation, test engineering, flight testing or a closely related discipline, ideally on aerospace or robotic systems.
A structured, systems-level approach: designing test plans, defining metrics, a statistical mindset for noisy flight data, and the ability to reason about a whole platform (airframe, avionics, GNC, RF) rather than a single subsystem.
Comfortable in the field: hands-on setup and execution of outdoor campaigns, with enough piloting interest/ability to work closely with the technician
Clear communicator, able to document rigorously and feed results back to engineering teams; able to manage a small team and work with varied backgrounds.
Working-level English; French or Arabic is a strong plus.
Valid driving licence and willingness to travel for field campaigns, with occasional trips abroad
Bonus: experience with autopilots/flight computers, telemetry and log analysis, basic Linux.
We look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI.
Autonomous defense systems and C2 platforms
Harmattan AI builds vertically integrated autonomous defense systems for NATO and allied forces. Its products include layered air defence, coordinated ISR and strike UAVs, electronic-warfare tools, and command-and-control platforms, all powered by a software-defined autonomy stack. The systems are designed to operate together, with autonomous decision-making, sensor fusion, and mission execution through its C2 framework. The company differentiates itself through large-scale industrial manufacturing, secured Programs of Record with European and UK defense ministries, and a strategic partnership with Dassault Aviation to embed Harmattan’s controlled autonomy into combat-air systems such as Rafale F5 and UCAS. The goal is to provide trusted, scalable autonomous solutions for defense missions, expanding globally and embedding autonomy into partner platforms to strengthen allied capabilities.
