Electrical Engineer (Ground Control System)

Signal Processing Engineer (RF Processing & Analytics); Paris; Sur place; EUR 70 000 - 95 000; Plein temps

Résumé du poste

Harmattan AI is seeking a senior hardware engineer to design and ship complex RF/mixed-signal PCBs for rugged defense systems. You will own schematics, layouts, bring-up, and collaboration with software and mechanical teams to ensure robust, manufacturable hardware.

The role requires autonomous work in a small team and a focus on cost and reliability. You will work on PCB architecture, RF impedance matching, EMC considerations, and the full production handoff including BOM management and DFM/DFA

Qualifications

• Senior hardware engineer with proven PCB design and production experience.
• Strong schematics, layout, and bring-up discipline with cost awareness.
• Ability to bridge hardware and firmware in a small autonomous team.

Responsabilités

• Design complete schematics for mixed-signal and RF boards from power to digital and RF sections.
• Lead board placement and routing with focus on signal integrity and RF constraints.
• Select components with cost and supply in mind, optimise BOM for mass production.
• Lead hardware bring-up and debug using bench equipment and write bring-up scripts as needed.
• Address EMC/ RF challenges and ensure RF performance and impedance matching.
• Collaborate with Embedded SW to define hardware/interfaces and support firmware bring-up.
• Coordinate with Mechanical for PCB integration into enclosures and thermal management.
• Qualify PCB manufacturers and assembly houses and support NPI transitions.
• Maintain up-to-date documentation of schematics, layouts, and test procedures.

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 developing new hardware products within the GCS module, including ruggedised drone controllers and long-range RF systems designed for demanding field environments. These products require dedicated electronics design with complex architecture in a constrained environment – PCBs integrating RF modules, microcontrollers, power management, and communication interfaces – optimised for cost at volume. The GCS team is seeking a dedicated hardware engineer to owner electronics design end-to-end and accelerate the path to production milestones.

Ideal candidate

A senior hardware engineer who has designed and shipped complex PCBs, ideally mixing digital and power, into production. They are rigorous on schematics, layout, and bring-up, and have a strong instinct for cost and manufacturability. They are comfortable working autonomously in a small team and can bridge hardware and firmware.

Skills required

• PCB schematic and layout design (Altium Designer preferred)
• RF PCB design: controlled impedance, antenna matching, EMC management
• Mixed-signal design: power management, MCU interfaces, communication buses (SPI, I2C, UART, USB, CAN)
• Hardware bring-up and debug: bench equipment proficiency
• DFM/DFA for PCB manufacturing and assembly
• Component selection and BOM management

Responsibilities:

• Schematic Design - Design complete schematics for mixed-signal and RF boards, from power to digital and RF sections.
• PCB Layout & Routing - Perform or lead board placement and routing with attention to signal integrity, EMC, and RF constraints (6-8 layer layout, controlled impedance, ground planes, and RF traces).
• Component Selection & BOM Optimisation – Select components with cost, availability, and reliability in mind; drive BOM cost reduction for mass production volumes.
• Hardware Bring-up & Debug - Lead board bring-up and debug issues with oscilloscopes, spectrum analysers, and other bench equipment; write bring-up scripts when needed.
• EMC & RF Compliance - Address EMC challenges; ensure signal integrity across the board and correct RF performance (antenna impedance matching and power levels).
• Collaboration with Embedded SW - Work closely with the embedded software engineer to define hardware/software interfaces; support firmware bring-up.
• Collaboration with Mechanical - Ensure seamless PCB integration into mechanical enclosures (connectors, mounting, thermal, shielding).
• Supplier & Manufacturing Ramp-up - Qualify PCB manufacturers and assembly houses; support DFM/DFA review for production; manage NPI transitions.
• Documentation - Maintain schematics, layout files, test procedures, and hardware specifications.

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