Résumé du poste

Harmattan AI is seeking an Optical Engineer to own the optical performance of EO/IR imaging payloads in the Gimbal team. You will follow products from sizing and prototyping through validation and mass production, working with the mechanical, electronics, software, CV and industrialization teams.

The role requires a Master’s in optics and 3+ years of experience; you’ll shape future products in a demanding startup environment.

Qualifications

• Master's degree in optics or engineering with optics specialization.
• 3+ years of experience in optical engineering.
• Experience sizing electro-optical or infrared systems.
• Hands-on experience with camera calibration, MTF, and NETD.
• Experience building optical test benches from architecture to integration.
• Strong background in image processing: distortion, gamma, and correction.
• Experience with thermal cameras is a strong plus.
• Autonomous, rigorous, and able to iterate in a startup environment.

Responsabilités

• Sizing and designing EO/IR payloads balancing field of view, resolution, range, and sensor choice.
• Select lenses or sensors or lead custom optical designs against image quality targets.
• Build and maintain optical test benches for development, validation, and production.
• Measure image quality: MTF, focus, boresight, distortion, NETD.
• Develop the calibration pipeline with software and perception teams.
• Integrate optics into mechanical assemblies with tolerancing and sealing.
• Collaborate with optical suppliers and support industrialization of lenses, sensors, components.
• Run field tests to assess image quality in real operating conditions.

Description du poste

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 an Optical Engineer in the Gimbal team, you are responsible for the optical performance of our EO/IR imaging payloads, which drive image quality, detection range, and robustness in operation. You will work on current products and shape the design of future ones. You follow each product from sizing and prototyping through validation and mass production, working closely with the mechanical, electronics, software, computer vision and industrialization teams.

Responsibilities

• Sizing and design of EO/IR imaging payloads, arbitrating between field of view, resolution, range, and sensor choice.

• Select lenses and sensors, or lead custom optical designs, against image quality and robustness targets.

• Design, build, and maintain optical test benches for development, validation, and production.

• Measure and validate image quality: MTF, focus, boresight, distortion, and NETD for infrared.

• Develop the camera calibration pipeline (intrinsics, extrinsics, distortion, photometric and radiometric correction) with the software and perception teams.

• Integrate optics into mechanical assemblies, covering tolerancing, athermalisation, windows, coatings, and sealing.

• Investigate optical issues across the product life cycle, from prototype to series production.

• Manage optical suppliers and support industrialization of lenses, sensors, and components.

• Run field tests to assess image quality in real operating conditions.

Candidate Requirements

• Master's degree or engineering degree with a specialization in optics.

• 3+ years of experience in optical engineering, ideally on camera or imaging systems.

• Proven experience sizing an electro-optical or infrared optical system.

• Hands‑on experience with standard optical measurements such as camera calibration, MTF, and NETD.

• Experience developing optical test benches, from architecture to validation and integration.

• Solid grounding in image processing: distortion, gamma, and geometric and photometric correction.

• Experience with thermal cameras is a strong plus.

• Hands‑on, rigorous, and pragmatic, with the autonomy to iterate fast in a startup environment.

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