## 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**
