## 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 Signal Processing Engineer, you own the algorithmic core of our drone-to-ground radio link — the system that keeps drones connected, controllable, and streaming in contested environments. You design the waveform, the anti-jam logic, and the signal intelligence that turn radio waves into a reliable link under hostile conditions, working hand-in-hand with RF hardware, FPGA, and software engineers to bring your algorithms from theory to flight.

**Responsibilities**

- **Waveform Design:** Design modulation, coding, and equalization schemes for a robust, low-latency radio link.
- **Anti-Jamming (ECCM):** Build algorithms that keep the radio link alive under active jamming.
- **Signal Intelligence (SIGINT):** Detect and characterize other radio emitters in the operating environment.
- **Mesh Networking:** Optimize protocols so multiple radio units share the airwaves without collision.
- **AI-Assisted Processing:** Apply machine learning to jamming detection and channel prediction where it improves field robustness.
- **Field Validation:** Take algorithms from simulation to lab bench to real flight test.
- **Radio System Integration:** Work daily with RF hardware and FPGA engineers to bring designs into a fielded radio.

**Candidate Requirements**

- Master's or PhD in Electrical Engineering, Signal Processing, or Applied Mathematics.
- 8-12 years designing radio or communication systems, from algorithms to deployed products.
- Hands-on experience with modem or waveform design: modulation, coding, synchronization, equalization.
- Solid grounding in probability, DSP, and information theory; comfortable deriving solutions from first principles.
- Practical awareness of RF hardware and FPGA constraints (latency, precision, real-time processing).
- Exposure to ECCM, SIGINT, or mesh networking is a strong plus.
- Clear communicator across RF, FPGA, and software disciplines.
- Fluency in English required; French is a plus.

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