Who we are

Build the devices that will power sustainable electrification worldwide!

AlpSemi is an industrial deep tech company building next-generation semiconductor power switches.

We are driving a generational technology shift: enabling the large-scale adoption of Solid-State Circuit Breakers, a breakthrough technology set to transform power protection and distribution, much like LEDs transformed lightning and digital cameras transformed photography.

Our technologies address one of the biggest challenges of our time: enabling sustainable electrification at scale by optimizing power consumption across global markets such as IA data centers, thereby improving access to electricity worldwide.

Job description

As part of our growth, we are hiring an Application Engineer to support the adoption and deployment of innovative Solid-State Circuit Breaker (SSCB) solutions for next-generation power electronics systems. You will explore new application opportunities, develop customer-oriented demonstrators, and collaborate with industrial and research partners to accelerate the integration of advanced semiconductor-based protection technologies.

Explore and qualify new applications for semiconductor-based power protection technologies and SSCB solutions.

Design, develop, and validate demonstrators, prototypes, and customer evaluation platforms showcasing SSCB performance and benefits.

Investigate the integration of Wide Bandgap (WBG) devices into fast, selective, and intelligent protection functions.

Develop advanced test benches and perform characterization campaigns including fast transient, short-circuit, surge, and Safe Operating Area (SOA) testing.

Responsibilities:

Collaborate with customers and external partners to co-develop innovative AC and DC power distribution architectures for applications such as smart buildings, data centers, electric vehicles, and aerospace systems.

Build and maintain expertise in: WBG semiconductor devices, device physical limitations (SOA, dv/dt, di/dt, thermal constraints) and protection and fast interruption topologies.

Prepare application notes, technical reports, and design guidelines.

Monitor technology trends and market developments related to electronic protection solutions and power distribution systems.

Job requirements

Engineering degree or MSc in Power Electronics, Electrical Engineering, Electronics, or a related field.

5 to 10 years Experience in power electronics and power semiconductor technologies.

Understanding of fast electrical protection challenges including short-circuit protection, current limiting, and protection coordination.

Proficiency with laboratory equipment such as high-bandwidth oscilloscopes, fast current probes, power supplies, and electronic loads.

Strong analytical skills, hands-on experimental mindset, and ability to formalize technical findings.

Comfortable working in collaborative and multidisciplinary environments involving industrial and academic partners.

Autonomous, rigorous, and able to manage multiple projects simultaneously.

Strong communication and teamwork skills.
