About the role
About Hades
Hades is a modern resource extraction company on a mission to transform how the world accesses critical resources and energy. Founded in 2025, we’re developing ultra-deep laser drilling technologies that push the limits of what’s possible underground. Based in Munich, we’ve raised over €20M in funding from leading European resilience investors including HV Capital, Headline, Project A and Visionaries Tomorrow. We’re now building a world-class team to bring this vision to life.
The Role
As Test & Instrumentation Engineer, you will design, build and operate the test benches that develop, characterise and qualify the Hades sensor suite. You decide whether a sensor is good enough to go into the drilling system, and you prove it with data. You will take each sensor from datasheet to qualified component: bench characterisation, calibration against traceable references, and environmental testing under the temperature, pressure, vibration and laser-light conditions it will see in the field. The data your benches produce defines what the drilling system can see. This is a foundational role with significant ownership. You will work closely with our electronics, optics, mechanical and software engineers, and you will set the bar for measurement quality across the company.
Responsibilities * Design, build and operate test benches for the sensor suite: characterisation, calibration and environmental qualification of sensors for temperature, pressure, flow, strain, vibration, displacement and optical power * Define sensor test specifications with the engineering team and turn requirements into test plans, acceptance criteria and pass/fail evidence * Characterise sensor performance: accuracy, linearity, hysteresis, noise, drift, bandwidth and response time, including behaviour under laser exposure, high temperature and high pressure * Run environmental and lifetime testing (thermal cycling, pressure, shock and vibration, ageing) to qualify sensors and their electronics for downhole and surface use * Own calibration: build reference setups, define procedures, ensure traceability to accredited standards and quantify measurement uncertainty for every sensor we qualify * Design the bench electronics: signal conditioning, grounding and shielding, data acquisition and safety interlocks for pressure, thermal and laser testing * Automate test sequences and build the pipeline from sensor to dataset (logging, processing and reporting) so results are reproducible, traceable and quick to access * Evaluate sensor suppliers and new sensing technologies, and feed results straight back into sensor selection and system design * Support validation of the sensor suite on drilling rigs and in the field
Qualifications * BSc or MSc in Electrical Engineering, Measurement Engineering, Physics, Mechatronics or a related field (recent graduates welcome) * Hands-on experience building test benches or measurement setups, gained in industry, internships, working-student positions, a thesis or student teams * Deep understanding of sensor technology, signal conditioning and noise: you know why a thermocouple reading drifts, how to ground a bench and how to keep EMI out of a measurement * Working knowledge of measurement uncertainty and calibration (GUM, traceability, reference standards) * Experience with data acquisition hardware and software, e.g. NI hardware/LabVIEW, or comparable DAQ systems * Proficiency in Python for test automation and data analysis, including statistics on test data; Git and clean, documented code * Confidence in the lab: reading and drawing schematics, wiring, soldering, and working with oscilloscopes, DAQs, power supplies and reference instruments * Rigour in documentation: test plans, procedures and reports others can reproduce * Evidence of exceptional ability, such as top-of-class academics, ambitious side projects, competition or hackathon wins, startup experience or equivalent * Excellent written and spoken English; German is a plus * Willing to live in the greater Munich area
Nice to have * Experience with harsh-environment or downhole sensing (high pressure, high temperature, vibration), e.g. from oil and gas, geothermal, aerospace or automotive * Optical and photonic sensing: photodiodes, pyrometers, thermal cameras or fibre-optic sensors (FBG, distributed temperature sensing) * Environmental and qualification testing to standards such as IEC 60068, and working with pressure equipment safely * Calibration lab practice (ISO/IEC 17025, DAkkS) * Embedded systems or C/C++ for sensor electronics and firmware * Laser safety (EN 60825-1) and electrical safety for test equipment (EN 61010-1)
