## About the role

##### 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.

**Overview**

Harmattan AI is scaling multiple hardware programmes and needs internal tooling to help the engineering teams develop and validate products faster. The new R&D Hardware Tooling team builds the rigs, fixtures, and instrumentation that accelerate design, bring-up, characterisation, and validation across every hardware product. These are development and validation tools used in the lab and in R&D workflows — not production test equipment for a manufacturing line. This role owns the electronics of those tools end-to-end: breakout and interface boards, instrumentation and DAQ hardware, signal-conditioning and debug-access boards, and RF characterisation fixtures. Unlike product electronics optimised for cost at volume, tooling electronics prioritise measurement accuracy, flexibility, robustness, and fast turnaround.

**Ideal candidate**

A hardware engineer who has designed instrumentation, breakout, or DAQ electronics – or product PCBs – and now wants to build the tools. Rigorous on schematics, layout, and bring-up, with a strong instinct for measurement integrity and quick, reconfigurable designs. Comfortable working autonomously in a small team and able to bridge hardware and firmware, working closely with the tooling software engineer.

**Required skills**

- PCB schematic and layout design (Altium Designer preferred)

- Mixed-signal design: power, MCU interfaces, comms buses (SPI, I2C, UART, USB, CAN)

- Instrumentation / DAQ / breakout design (signal conditioning, measurement front-ends)

- RF / controlled impedance / EMC — nice to have

- Hardware bring-up and bench debug; measurement integrity and calibration

- Component selection and BOM for low-volume, high-mix tooling**Responsibilities:**

- Schematic Design — design mixed-signal, power, and RF instrumentation and breakout boards.

- PCB Layout & Routing — layout with attention to signal integrity, measurement accuracy, EMC, and (where relevant) controlled impedance and RF traces.

- Fixture & Interface Design — design device-under-development interfaces (breakouts, interposers, connectors, signal access) that are reliable and easy to reconfigure as designs change.

- Component & Instrument Selection — choose components and decide COTS instrument vs. in-house board; build BOMs for low-volume, high-mix tooling.

- Bring-up & Debug — lead fixture bring-up; debug with oscilloscope, spectrum/logic analyzer, and bench equipment.

- Measurement Integrity & EMC — ensure accuracy, grounding, shielding, and signal integrity; manage calibration where needed.

- Collaboration with Tooling SW — define hardware/software interfaces; support fixture-firmware and instrument-control bring-up.

- Collaboration with Tooling Mech — integrate boards into rigs and benches (mounting, actuation, connectors, thermal, shielding).

- Collaboration with Product Teams — capture each product's development and validation measurement needs.

- Documentation — maintain schematics, layouts, fixture build docs, and calibration/measurement procedures.We look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI.
