Company Overview

INAUTALENT is supporting the International Space Federation (ISF), a pioneering R&D organization based in Cluses (French Alps), in strengthening its engineering team in Switzerland.

ISF conducts experimental research at the frontier of physics and advanced engineering, developing high-energy electronic systems to support breakthrough technologies related to gravity-control propulsion and quantum-vacuum energy.

The organization works in close collaboration with international academic partners to transform bold scientific concepts into real, testable hardware.

Job Description

We are looking for a talented and hands-on Senior Analog & Power Electronics Hardware Engineer to join our innovative team.

This is a fantastic opportunity for an engineer who loves bringing designs to life on the bench - owning projects from initial concept through to working prototypes.

You will focus on designing, building, and debugging advanced analog and power boards, particularly for power amplification, high-current drive, and impedance-controlled systems in specialized applications, such as driving challenging low-impedance loads across k Hz to MHz frequencies.

This role is strongly hands-on and requires a practical mindset, a deep understanding of real-world component behavior, and the ability to contribute to cutting-edge experimental hardware.

Key Responsibilities

- Lead full-custom analog and power board development, including

• schematics
• simulations
• PCB layout guidance
• prototyping
• testing and iterative refinement
• Design robust power-stage topologies (half-bridge, full-bridge, Class A/AB/D/E, or switched-mode) capable of delivering high currents and managing high voltages safely.
• Apply impedance matching and resonant circuit techniques for efficient power delivery across wide frequency ranges (typically 100 k Hz - 100 MHz).
• Take end-to-end ownership of hardware projects while collaborating with the team on layout, fabrication, and integration as needed.
• Use laboratory equipment confidently for validation and debugging, including:
• oscilloscopes with HV/current probes
• spectrum analyzers
• VNAs
• impedance analyzers
• Work closely with cross-functional teams to integrate designs into larger systems, ensuring reliability under real-world operating conditions.
• Iterate quickly based on bench results to achieve performance, safety, and manufacturability goals.

Required Qualifications

• Education: Bachelor’s or Master’s degree in Electrical Engineering, Electronics, or a closely related field.

Experience

• 7+ years of hands-on experience in analog/power electronics design (or 5+ years with particularly strong relevant projects).

- Proven track record designing full-custom analog boards, including

• power amplification stages and switched-mode topologies
• transistors (BJT/MOSFET), diodes, passives, and active components in high-performance circuits
• impedance matching networks (L-networks, π-networks, transformers, etc.) between stages and to loads
• Solid practical knowledge of passive components, including capacitor dielectrics (X7R vs.

C0G/NP0, film, electrolytic), ESR/ESL effects, parasitics, and real-world deviations from datasheet specifications.

• Experience with high-voltage considerations, including k V-level isolation, gate drivers (opto, bootstrap, transformers), creepage/clearance rules, and safety standards.
• Proficiency with schematic capture and PCB layout tools (Ki Cad preferred; Altium or equivalents also welcome).
• Comfort using SPICE simulation tools (LTspice, SIMetrix, PSpice) for transient, stability, and matching analysis.
• Strong hands-on
