## Job description

## 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

As a confirmed Radar Signal Processing Engineer on Harmattan AI's Radar team in Paris, you will own the signal processing algorithms behind our next-generation airborne radar payload. You will take full ownership of your workstream, from algorithmic research through embedded implementation and flight validation, working with high autonomy and minimal oversight. You will work closely with the EW and RF analytics teams to translate product-level requirements into deployed, mission-ready capabilities.

## Responsibilities

- Design and implement near-real-time algorithms for radar image formation, including inverse SAR (ISAR) processing of moving targets.
- Develop and refine detection and tracking algorithms (e.g., EKF/UKF-based approaches) for moving target indication on airborne radar data.
- Build jamming estimation capabilities, combining out-of-band spectral sniffing with in-band spatial covariance analysis, and the adaptive logic that drives radar behavior in response.
- Contribute radar-derived observables and algorithms that support navigation when GNSS is unavailable.
- Prototype and port algorithms onto the selected embedded computing platform, balancing algorithmic performance against real-time and resource constraints.
- Validate algorithms end-to-end through hardware-in-the-loop bench testing, anechoic chamber campaigns, and real flight conditions, iterating quickly on results.
- Work closely with the EW and RF analytics modules to align signal processing development with system-level requirements.

Candidate Requirements

- 2 to 5 years of confirmed, hands-on experience in radar signal processing, gained in the defense or automotive radar industry preferably.
- Solid experience in Signal Processing on radar systems, either FMCW or pulsed, is required; exposure to moving target tracking, ECCM, radar-based navigation, or live/real-time processing is a strong plus.
- Strong theoretical foundations and genuine hands-on comfort with the underlying mathematics, not reliance on off-the-shelf tools or LLM-generated solutions.
- A quick thinker, comfortable taking full ownership of a technical scope end-to-end with minimal oversight.
- Comfortable working in a fast, iterative cycle: writing code, running hardware-in-the-loop tests, and pushing validated changes independently.

We look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI.

## About Harmattan AI

## Company Overview
- **One-liner**: Harmattan AI builds autonomous defense systems—including strike and surveillance drones—using AI-driven autonomy and real-time intelligence for allied forces.
- **Entity Type**: Private (Series B, unicorn status)
- **Headquarters**: Paris, France
- **Founded**: 2024
- **Founders**: Mouad M’Ghari (CEO & Co‑founder)

## Core Business
- **Primary industry**: Defense & autonomous systems
- **Target customers**: B2G – NATO member states, ministries of defence (UK, France, and others)
- **Mission**: Deliver scalable, sovereign AI capabilities to allied forces by building mission‑ready autonomous systems that respond in real time, adapt under pressure, and deliver an edge in contested environments. [harmattan.ai](https://harmattan.ai/)

## Products & Services
- **Platform Autonomy**: AI‑driven autonomy layer for drones, enabling real‑time decision‑making and adaptation.
- **Mission Orchestration**: Software for coordinating multiple autonomous assets (e.g., collaborative air combat).
- **Precision Strike**: Attritable strike drones with embedded AI for target engagement.
- **VSHORAD (Very Short‑Range Air Defence)**: Counter‑drone interception systems.
- **Persistent ISR (Intelligence, Surveillance, Reconnaissance)**: Autonomous surveillance platforms for continuous battlefield awareness.
- **Electronic Warfare Platforms**: Systems for electronic attack and protection. [harmattan.ai](https://harmattan.ai/)

## Market Standing
- **Valuation**: $1.4 billion (as of January 2026, after Series B). [tech.eu](https://tech.eu/2026/01/12/french-startup-harmattan-ai-hits-unicorn-status-as-it-strikes-deal-with-french-aerospace-group/)
- **Key Metric**: Total funding ~$240 million ($200 M Series B led by Dassault Aviation + over $40 M prior). [tech.eu](https://tech.eu/2026/01/12/french-startup-harmattan-ai-hits-unicorn-status-as-it-strikes-deal-with-french-aerospace-group/)
- **Notable Investors/Partners**: Dassault Aviation (lead investor & strategic partner), multiple NATO allies as customers.
- **Growth Signals**:
  - Achieved unicorn status within two years of founding.
  - Awarded several “programs of record” by UK and French Ministries of Defence. [tech.eu](https://tech.eu/2026/01/12/french-startup-harmattan-ai-hits-unicorn-status-as-it-strikes-deal-with-french-aerospace-group/)
  - Scaling industrial manufacturing of drone interception and electronic warfare platforms.
  - Headcount grew to 131 employees (Built In estimate). [builtin.com](https://builtin.com/company/harmattan-ai)

## Competitive Advantages
- **Two‑layer autonomy model**: Combines platform‑level AI with mission‑orchestration software for coordinated, scalable autonomous forces.
- **Sovereign AI**: Focus on delivering non‑dependent capabilities to allied nations, differentiating from US‑centric primes.
- **Attritable systems**: Cost‑effective, expendable drones that enable mass deployment without prohibitive losses.
- **Speed to relevance**: Claims rapid iteration and deployment cycles, with conflict‑ready production. [harmattan.ai](https://harmattan.ai/)

## Strategic Focus
- Expand product offering into new operational domains (e.g., collaborative air combat with Dassault Aviation).
- Scale industrial manufacturing of drone interception, electronic warfare, and ISR platforms.
- Deepen integration of embedded AI into next‑generation air combat systems (future combat air systems). [tech.eu](https://tech.eu/2026/01/12/french-startup-harmattan-ai-hits-unicorn-status-as-it-strikes-deal-with-french-aerospace-group/)

## Why Work Here
