Electrical Engineer

At Praxa Sense, we’re redefining non-invasive health monitoring with our optical innovation ALIS – a speckle-based biosensor enabling new frontiers in remote vital sign tracking.

We’re looking for a fulltime Electrical Engineer to guide the hardware development of our optical speckle sensor platform, combining CMOS imaging, laser illumination, and mixed-signal electronics. You will own the electrical design from architecture through validation and production, working closely with optics and algorithm teams.

Who we are

At Praxa Sense, we’re redefining non-invasive health monitoring with our optical innovation ALIS – a speckle-based biosensor enabling new frontiers in remote vital sign tracking.

What you will do

• Source, design and integrate electronics for optical sensing systems, including CMOS image sensors, laser drivers, timing and synchronization, and low-noise analog-digital front ends.

Mixed-Signal & PCB Design

• Own schematic design and PCB layout for mixed-signal systems (power, analog, digital), with strong attention to signal integrity, noise, and EMC.

System Architecture

• Define electrical architectures and interfaces across sensors, processors, and peripherals, balancing performance, manufacturability, and robustness.

Bring-up, Testing & Validation

• Lead board bring-up, debugging, calibration, and validation in lab environments; support DFM/DFT and transitions to manufacturing.

What we are looking for

• 1+ years in electronics development for sensors, imaging systems, or optical instrumentation.
• Analog & digital circuit design
• PCB design (Altium)
• Low-noise power and mixed-signal systems
• Interfaces such as I2C, SPI, UART (plus imaging interfaces is a plus)
• Familiarity with CMOS image sensors, optical systems, or laser-based instrumentation. Experience with laser safety and optical timing is a plus.
• Pragmatic, hands-on, comfortable working across hardware–software–algorithm boundaries in a lean team.

What we offer

• A pivotal role in building a deep-tech biosensing product.
• Direct collaboration with experts in optics, signal processing, and data science.
• The chance to shape how world-leading companies integrate our technology.
• Hybrid work culture: in-person collaboration in Delft at least 3 days/week, work from home when you need focus.
• 25 paid holiday days per year.
• Budget for personal development and your home office.
• The satisfaction of building technology that directly improves health monitoring.
