Their flagship products combine advanced sensor systems, embedded software, and machine learning to deliver highly personalized and responsive user experiences. With a strong engineering culture and cross-functional collaboration, the team is focused on solving complex real-world challenges in a meaningful, impact-driven domain.

About the Role

As a Principal Electronics Design Engineer, you will act as the technical owner of the electronics domain for one of our key hardware products. This is not a typical Senior Individual Contributor role — it is a high-ownership engineering position with a strong influence on product architecture, technical decisions, and long-term system evolution.

You will work closely with the CPO and CTO, participate in architectural discussions across projects, and help shape the technical direction not only of the current product, but of future hardware initiatives.

What You Will Do

Own and evolve the electronics architecture from EVT stage through market launch and further product generations

Make key technical trade-off decisions between performance, power consumption, size, cost, reliability, and manufacturability

Lead the full hardware development cycle: from product requirements to validation and mass production readiness

Verify and validate hardware designs, troubleshoot complex issues, and drive them to resolution

Assemble prototypes or manage prototype production via EMS partners

Conduct schematic, PCB, and documentation design reviews

Create and improve manufacturing and test documentation

Design tools and solutions for QA, Test, and Manufacturing teams

Support EMC/ESD testing and certification activities

Identify and manage technical risks in the electronics domain

Work directly with the CPO and CTO on product architecture, roadmap planning, and critical decisions

Participate in cross-project peer reviews, sharing expertise and contributing to a strong engineering culture

Support manufacturing and continuously improve existing products and internal design processes

Desirable Experience and Skills

Proven experience delivering market-ready electronic products end-to-end

Strong background in schematic and PCB design using Altium Designer

Experience with SPICE simulation

Solid understanding of signal integrity, power integrity, and high-speed signal propagation

Experience with rigid-flex / FPC designs and dense multilayer PCBs (up to 12 layers)

Strong knowledge of analog electronics

Experience with SI/PI simulation and debugging

Scripting skills (Python, Matlab)

Product-oriented mindset and comfort working in environments with technical uncertainty

Proficiency in English (Upper-Intermediate+), Ukrainian (native)

Preferred Experience

Experience in bioengineering, wearables, BT/BLE, or IoT products

Background in high-growth startups or emerging technology companies

Awareness of CE / FDA certification requirements and IP protection considerations

Growth Opportunities

Long-term ownership of a product with multiple planned generations

Optional opportunity, after key milestones, to transition into leading electronics development for a new wearable device built from scratch

Close collaboration with executive leadership and influence on future hardware strategy

What We Offer

Work on products that meaningfully improve people's lives

Well-equipped hardware lab and full engineering support

Fast decision-making and a strong culture of ownership

Competitive compensation

Opportunities for deep technical growth and long-term impact

A mission-driven, passionate team
