Hardware Test Engineer

Optics11 is a fast-growing high-tech company based in Amsterdam, developing advanced fiber optic sensing systems for the most demanding environments. Our technology detects the earliest signs of failure in critical assets – from high-voltage energy infrastructure to subsea and defense applications – and gives our customers precise, real-time data they can act on.
Within our Underwater Security business we develop sensing technologies that help detect and monitor underwater threats. Our solutions include OptiBarrier, designed for immediate, over-the-horizon threat detection, and OptiArray, our low-power optical thin-line towed array for unmanned underwater vehicles and submarines.

Role Overview
As a Hardware Test Engineer at Optics11, you play a key role in ensuring the quality, reliability, and performance of our fiber-optic sensing systems. You develop and execute hardware tests at board and sub-system level, identifying potential issues early and helping our engineers deliver robust, production-ready solutions.

Combining hands-on hardware engineering with test automation, you build test setups, analyze results, support prototype development, and help transfer testing processes from R&D to production.
You will be part of our Sensing Platform Team, working closely with multidisciplinary engineering teams, production, and external partners.

What You'll Do
Hardware Testing & Automation

• Develop and execute test plans and procedures for electronic boards, assemblies, and sub-systems.

• Design and maintain test setups, fixtures, and jigs for functional, electrical, and optical testing.

• Perform environmental, stability, and robustness testing, including thermal cycling, vibration, and EMC/ESD pre-compliance.

• Develop Python-based test automation for instrument control, data logging, and analysis.

• Document test procedures, results, and findings, ensuring clear traceability and reproducibility.

Prototyping & Production Support

• Support prototype assembly, soldering, rework, cable assembly, and fiber handling and splicing.

• Develop and improve production and Factory Acceptance Test (FAT) setups, procedures, and test jigs.

• Support troubleshooting, repairs, and root-cause investigations during development and production.

• Maintain an organized, safe, and well-equipped R&D laboratory, including equipment calibration and materials management.

Technical Analysis & Continuous Improvement

• Analyze test results to evaluate hardware performance, identify risks, and support engineering decisions.

• Investigate hardware failures and collaborate with design engineers on corrective actions.

• Contribute to design-for-test and design-for-manufacturing improvements.

• Identify opportunities to improve test methods, automation, and product reliability.

Collaboration & Delivery

• Work closely with Electronics, Photonics, Embedded Software, Mechanical Engineering, IVVQ, and production teams.

• Support the handover of tested hardware and documentation to integration, validation, and production teams.

• Independently plan and execute assigned activities, communicating progress, risks, and dependencies.

• Share technical knowledge, contribute to design reviews, and support continuous improvement across the team.

What we offer

• Join one of Europe’s fastest-growing deep-tech scale-ups.

• Real impact: your work directly shapes our growth and success.

• A great team in an international organization with colleagues from more than twenty nationalities.

• A competitive salary and benefits package.

• 30 days of holiday per year.

• Fresh team lunches five times a week, plus regular team activities and company events.

Qualifications

• BSc (HBO) in Electrical Engineering, Electronics, Mechatronics, Applied Physics, or a related technical discipline, or equivalent experience.

• 2+ years of relevant experience in hardware testing, test engineering, prototyping, or lab work on electronic or electro-optical products.

• Hands-on experience with laboratory instruments such as multimeters, oscilloscopes, power supplies, signal generators, and data loggers; experience with optical power meters is an advantage.

• Experience executing test plans and procedures, logging and analyzing measurement data, and documenting results in clear test reports.

• Good soldering and rework skills for through-hole and SMD components, including building custom cables and harnesses, and the ability to read schematics, PCB layouts, wiring diagrams, and assembly drawings.

• Experience with or good understanding of environmental testing (e.g. temperature, thermal cycling, vibration) and of EMC/ESD principles.

• Python skills for test automation, instrument control, and data analysis; experience with LabVIEW, embedded Linux or similar tools is advantageous.

• Awareness of ESD-safe working practices and lab safety, including laser safety, or willingness to be trained.

• A structured, practical, and hands-on working style, and real enjoyment of testing, finding problems, and getting hardware to work.

• Good communication skills in English and a collaborative working style.

• Eligible for EU/NATO security clearance.

Preferred

• Experience with fiber handling, connector cleaning and inspection, and fusion splicing.

• Experience with EMC pre-compliance measurements (e.g. EN 55032/CISPR 32 emissions, IEC 61000-4-x immunity) or environmental test standards (e.g. IEC 60068, MIL-STD-810).

• IPC certification (e.g. IPC-A-610 or IPC J-STD-001) or experience with ESD control programs (IEC 61340-5-1).

• Experience developing production test setups, test jigs, or programming fixtures, or supporting NPI and production transfer with electronics manufacturing partners.

• Experience in multidisciplinary high-tech product development (e.g. sensing, photonics, instrumentation, defence, or subsea).…
