Senior Electronics Design Engineer

Mission

Neko is redefining what prevention means, from treating illness when it arrives, to sustaining health before it's ever at risk. Our mission: make data-driven, preventative care accessible to more people, before symptoms appear.

In a single, non-invasive visit under an hour, proprietary technology and direct clinical care combine to deliver personalised, actionable insights. It's a team that thinks in 10x, not 10%. Every role here plays a part in building a world where prevention is the norm, and where your work genuinely helps people live longer, healthier lives.

About the role

We're looking for a hands-on Senior Electronics Design Engineer to join our Hardware & Firmware organization. You'll design and own electronics for sensor-dense medical systems, working closely with Mechanical, Firmware, Software, Verification & Validation, Manufacturing, and Production teams.

You'll carry the design across the full product lifecycle: early system trades and requirements, concept, schematic, layout, bring-up, verification, certification, and into production. The device has to give the same reading in every clinic, every time, so robustness and data quality are design constraints from day one rather than something verification catches later.

This is a practical, lab-facing role for engineers who want to see their designs deployed in real clinical environments. We're looking for leadership through design ownership.

What you'll do

• Own electronics design end-to-end, from system trades and requirements through schematic, layout, verification, certification, and production support

• Design robust mixed-signal PCBs for sensor-dense medical systems, balancing signal integrity, power, thermal, and EMC constraints

• Select and integrate MCUs / DSPs and key components, working closely with firmware and software teams

• Lead board bring-up, debugging, and root-cause analysis of prototypes and production hardware

• Design for manufacture and test, and support the transfer into production

• Collaborate cross-functionally to keep designs manufacturable, testable, compliant, and scalable

What you bring

• Hands-on experience with both schematic capture and PCB layout

• 5+ years of hands-on electronics product development, with products that reached production

• Strong mixed-signal design, including simulation

• Solid understanding of power design, signal integrity, and EMC/EMI in real products

• Board bring-up, debugging, and lab instrumentation in embedded systems

• Comfortable working autonomously, taking an open-ended problem through to a design and the reasoning behind it

• Degree in Electrical Engineering or equivalent practical experience

• Fluent English (C1 or above)

Bonus points

• Experience in medical devices or another regulated industry, or familiarity with IEC 60601

• Sensor signal conditioning

• Switching power converters, magnetics, analog control loops, or motor inverters

• High-performance digital: processors, FPGAs, memory, network switches

• RF design or RF-sensitive systems

• Test interfaces or test systems (Python, LabVIEW, MATLAB)

Why join this team

You'd own boards, not sections of boards. From the first system trade to the first unit off the line, the design is yours.

Complete design freedom. You make the design calls. Nobody hands you a topology and asks you to route it. The hierarchy is flat, so the path from a decision to a built board is short.

Hardware with real constraints. Sensor-dense, mixed-signal, and every constraint pulling against the others: signal integrity, power, thermal, EMC, cost, manufacturability. There's no version of this that's routine.

The rest of the system is in the room. Mechanical, firmware, software, V&V and production all sit in the same Stockholm office. When a board misbehaves you walk over to the person whose subsystem it's talking to and sort it out that afternoon.

And it goes into clinics. Your boards end up in front of real people getting answers they wouldn't otherwise have.
