Software/Firmware Engineer

IPG Defense , a stand-alone business of IPG Photonics, was incorporated in 2026 to provide direct support for defense products. Headquartered in Huntsville, AL, IPG Defense is bringing commercial scale to laser defense systems, leveraging IPG Photonics' 36 years of experience in fiber laser technology. Our mission: develop and deliver the most advanced, next-generation laser defense solutions for military and civilian use — systems that accurately and reliably detect, track, target, and neutralize threats.

IPG Photonics is the world's leading developer and manufacturer of high-performance fiber lasers and amplifiers for diverse applications in numerous markets. Founded in 1990, IPG pioneered the development and commercialization of optical fiber-based lasers — a critical technology in our high-energy laser (HEL) systems, including the CROSSBOW program.

Your skills and experience will play a key role in shaping our growing organization, building our capabilities, and delivering on our mission. Join us and build a career that will shape the future of laser defense.

POSITION SUMMARY

The Software/Firmware Engineer plays a hands-on role in designing and implementing embedded control software for complex laser assemblies and beam-delivery subsystems. This position focuses on ARM-based processing, deterministic control, and low-latency communication to enable real-time power modulation, safety interlocks, and mission reliability in harsh environments. This opening targets a mid-level engineer; junior and senior candidates may also be considered, with level determined by experience and qualifications.

KEY RESPONSIBILITIES

Design, implement, and validate embedded firmware for laser, thermal, and beam-control subsystems.

Develop deterministic state-machine logic governing interlocks, firing sequences, and subsystem coordination.

Implement and tune digital control loops, including PID and feed-forward control, and validate loop performance using frequency-response (Bode) analysis.

Create and maintain real-time communication links between embedded controllers and higher-level command software.

Support board bring-up, hardware–software integration, and debugging using lab instruments (oscilloscopes, logic analyzers, JTAG debuggers).

Develop unit and integration tests and contribute to version control and continuous-integration practices for firmware.

Collaborate closely with optical, electrical, and systems engineers to ensure seamless integration across the full directed-energy platform.

Conduct firmware verification, configuration control, and field testing per MIL-STD requirements.

Support documentation, cybersecurity, and sustainment of deployed systems.
