Senior Electronics Engineer

300 million people need your skills to change their lives.

For thousands of years, blind individuals only had 2 mobility solutions: the guide dog and the white cane. Now, your work can change that. You can contribute to developing Pedestrian Autonomous Driving, applied in the Glasses for the Blind, the most innovative mobility solution that will empower millions to live a better life.

This is for the crazy ones, the ones who believe their work can change the world.

Some of the fields of interest:

• Research requirements from international standards.
• Simulate in tools such as LTspice or prototype assemblies to understand which components best suit the application.
• Align with the Mechanical Design, Software, and Research teams to have a holistic system overview on the development.
• Design the schematics containing mixed signal components, high-speed digital buses, and both power and low-power components.
• Design the layout according to industry standards for mass manufacturing but also with cost optimizations in mind. Take into consideration thermal dissipation, work closely together with the Mechanical Design team, and align with the prototyping methods available.
• Create BoMs, assist in the ordering of components, and assist in the assembly of the PCBs.
• Lead the testing of the PCBs, with support.
• Prototype using our own 0201 Pick-and-Place machines, CNC mills, cutting-edge 3D printers, in one of the best equipped prototyping labs in Romania.

Your skills

First and foremost, curiosity and grit. What you will be doing is on the cutting edge of what is possible and has never been done before.

• Senior level experience in Electronics Simulation, Schematic & Layout, and electronics mass manufacturing.
• Experience with Power Supply design for low-power electronics.
• Experience with high-speed signals (USB 3.1, for example).
• Experience with analog signals (conditioning, amplification, etc.) for audio and sensorics applications.
• Experience with microcontrollers and other digital components.
• Experience with lithium-ion batteries, BMSs, and similar.
• Experience with high-layer count (4-8 layers PCBs).
• Experience with PCB testing and debugging.
• Experience with Thermal Management in PCB design.
• Experience with EMC compliance and other standards.
• Experience with the Design for Manufacturing process for Electronics Engineering (PCBA manufacturing, communication with manufacturers, etc.)
• Knowledge of tools such as Altium, OrCAD, KiCAD, etc.
• Safety-critical design or automotive experience is a plus.
• DFMEA/FMEDA experience is valued.
• A very hands-on, proactive attitude and a desire to continuously build things.
• Strong documentation skills to write documentation.
• Graduate of technical universities or equivalent academics.
• Strong English skills.

Your life @.lumen

You will be part of the team that changed the world from Romania. Your work will be pushing limits to improve the lives of millions.

• Each day is different. There is no monotony here, just great challenges, a creative environment, and fun colleagues.

2. The most suited candidates meet us for an informal discussion

3. Next, we invite the best to join a challenge led by Octavian Coca

4. We get to meet the winner for the final interview with Cornel Amariei

About .lumen

.lumen builds Pedestrian Autonomous Driving, first showcased in the Glasses for the Blind.

There are over 300 million visually impaired individuals worldwide, and while technology advances, the most commonly used solutions for them—guide dogs and white canes—are thousands of years old. At .lumen, we are changing this paradigm.

.lumen is a research startup leveraging the most advanced AI, robotics, and neuroscience technologies to empower the blind. This is no easy task, and we are looking for the best in the world to help us achieve it.

In just four years, .lumen has become one of the most awarded start-ups globally. From opening Nvidia GTC in front of millions to winning the Red Dot: Luminary award and becoming the first Romanian company to raise over €9 million from the European Innovation Council (EIC), our journey has been remarkable.

Our work is already in the history books, and our story is still being written.
