Senior Hardware Engineer – Secure Embedded Systems; m​/f​/d

Position: Senior Hardware Engineer – Secure Embedded Systems (m/f/d)
Role Overview

We are seeking a Senior Hardware Engineer to design and deliver secure, ruggedized embedded hardware from initial concept through prototyping, qualification, and volume production.

This is a highly hands-on role covering PCB design, mixed-signal electronics, low-power embedded systems, sensor interfaces, hardware security, RF integration, ruggedization, rapid prototyping, and manufacturing
.

The successful candidate will own complex hardware designs, build and troubleshoot prototypes in the lab, and work closely with embedded software, mechanical, security, manufacturing, and systems engineering teams.

Key Responsibilities PCB Design & Hardware Development

• Design complex multi-layer mixed-signal and low-power PCBs
  , from schematic capture through layout and manufacturing release.
• Develop flex and rigid-flex designs
  , stack-ups, controlled-impedance interfaces, and designs using extended-temperature components.
• Own component selection, design reviews, schematic reviews, and PCB layout reviews.
• Design low-noise sensor front-ends
  , precision acquisition circuits, and standardized interfaces for third-party sensor integration.
• Develop battery-powered embedded architectures with careful power budgeting, sleep-state management, backup power, and power-path management
  .

Prototyping & Board Bring-Up

• Produce rapid PCB prototypes through external quick-turn fabrication and assembly suppliers.
• Prepare production packages including Gerber files, BOMs, pick-and-place data, assembly drawings, and manufacturing documentation
  .
• Perform DFM/DFA reviews
  , supplier coordination, incoming inspection, and first-article evaluation.
• Personally populate, solder, rework, debug, and bring up prototype PCBs.
• Perform fine-pitch SMD and through-hole soldering
  , hot-air/reflow rework, and microscope inspection.
• Design and build test fixtures, cabling, adapters, and development hardware.
• Create rapid mechanical prototypes using FDM/SLA 3D printing for enclosures, brackets, fixtures, and test assemblies.

Secure Hardware Engineering

• Develop hardware architectures incorporating secure elements, hardware root of trust, secure boot, protected key storage, secure provisioning, and debug-port protection
  .
• Design MCU-based systems using security features such as Arm Trust Zone-M and hardware cryptographic accelerators
  .
• Support key storage and zeroization
  , device identity, and secure provisioning.
• Design with awareness of physical attack techniques including probing, side-channel attacks, and fault injection
  .
• Work closely with embedded software and security engineers to implement end-to-end platform security.

Sensor & Connectivity Integration

• Design analog and digital sensor interfaces including precision ADCs, IMUs, environmental sensors, and other sensing technologies
  .
• Integrate industrial communication technologies such as RS-485/Modbus and 4-20 mA interfaces
  .
• Support RF and wireless integration including UWB, BLE, LoRa, Wi-Fi, and cellular IoT
  .
• Perform RF layout and radio-module integration, including antenna placement within sealed or ruggedized enclosures.

Ruggedization & Qualification

• Develop hardware for demanding operating environments using IP67/IP68 enclosures, sealed connectors, conformal coating, potting, extended-temperature components, and thermal-management techniques
  .
• Own environmental and reliability testing including temperature, humidity, vibration, shock, salt fog, corrosion, and accelerated aging
  .
• Lead root-cause analysis and corrective hardware redesign following qualification or reliability failures.
• Support EMC testing, radio approval, environmental compliance, physical-security certification, and hazardous-area requirements where applicable.
• Apply relevant MIL-STD environmental and EMC methods where required.
