Electronics Engineer – Mid to Senior Level

About Wellumio

Wellumio is a venture-backed medical device company on a mission to create universal access to diagnostic imaging.

Magnetic resonance is the gold standard modality in medical imaging due to its exceptional soft tissue contrast. However, its accessibility is limited by high costs and the need to transport patients to scanners. At Wellumio, we are driven by a simple yet transformative idea: instead of bringing patients to the scanner, we bring the scanner to the patients, wherever it is needed.

By providing point-of-care imaging, Wellumio enables healthcare professionals to deliver earlier diagnoses, faster treatments, and better outcomes. Our second-generation scanner, Axana, is 99% lighter than conventional MRI systems, making it the most portable head magnetic resonance imaging system in the global brain and neuroimaging market.

The company's first target application is acute stroke, a leading cause of human mortality and disability. Currently, only 1.5% of patients receive treatment within the critical time window due to reliance on in-hospital imaging. Wellumio's point-of-care solution addresses this, making effective stroke treatment accessible wherever patients are.

With stroke projected to cause 7.5 million deaths and cost $1 trillion annually by 2030, there is an urgent need for cost-effective technologies that can streamline care pathways for stroke and other neurological conditions where time is critical.

Why should you be part of Wellumio's success story?

To work with a talented and passionate team dedicated to positively impacting the medical device industry.
To grow your skills and knowledge through ongoing training and development opportunities.
To work in a dynamic environment that rewards creativity, innovation, hard work, and continuous improvement.

At Wellumio we're challenging dominant models of clinical service delivery by fusing technology, design innovation, medical expertise, and systems-level thinking to create imaging solutions that put the needs of patients first.

About the Role

We are seeking a practical and experienced Electronics Engineer to design, implement, test, and verify printed circuit board assemblies for advanced medical technology products.

Working as part of a multidisciplinary engineering team led by senior technical staff, the successful candidate will take approved system and hardware architectures and translate them into robust, manufacturable PCBAs. The role will involve detailed circuit design, schematic capture, PCB layout, prototype bring-up, debugging, verification, and support through design transfer.

The position may be appointed at either a mid or senior level depending on the candidate’s depth of experience, ability to work independently, and capability to deliver complex board designs with limited supervision.

Key Responsibilities PCBA Design and Implementation

Essential Qualifications and Experience

Bachelor’s degree or higher in Electrical Engineering, Electronic Engineering, Mechatronics Engineering, or a related discipline.
Demonstrated experience designing PCBAs from defined architectures and requirements through to tested and verified hardware.
Strong proficiency with Altium Designer.
Demonstrated experience completing both schematic capture and PCB layout.
Strong understanding of digital electronics and microcontroller- or processor-based systems.
Practical experience with low-voltage DC power supplies, regulation, power distribution, filtering, and protection.
Experience designing common embedded interfaces such as SPI, I²C, UART, USB, CAN, Ethernet, GPIO, and similar interfaces.
Strong understanding of grounding, decoupling, filtering, return paths, signal integrity, power integrity, thermal considerations, and electromagnetic compatibility.
Demonstrated hands-on experience with board bring-up, debugging, fault-finding, and verification testing.
Ability to produce clear schematics, PCB layouts, bills of materials, design calculations, test procedures, and technical reports.
Ability to work independently on defined board-development activities while operating effectively within a broader engineering team.
Strong attention to detail and a methodical approach to design and testing.

Desirable Experience

Experience developing electronics within a regulated industry such as medical devices, aerospace, automotive, defence, or industrial safety systems.
Familiarity with medical-device quality and risk-management standards, including:
ISO 13485
ISO 14971
IEC 60601
IEC 62304
Experience working within formal design-control, document-control, configuration-management, and engineering-change processes.
Experience conducting or contributing to Design FMEA, fault-tree analysis, or similar structured risk-analysis activities.
Embedded software capability at bare-metal, RTOS, or embedded Linux level.
Experience developing device drivers, board-support packages, diagnostic firmware, or production-test software.
RF circuit-design or RF integration experience.
Experience with antennas, RF modules, matching networks, wireless communications, or RF test equipment.
Experience supporting EMC design and formal EMC testing.
Experience with low-noise analogue circuitry, sensor interfaces, signal conditioning, or data-acquisition systems.
Experience designing battery-powered equipment, battery interfaces, charging systems, or power-monitoring circuitry.
Experience supporting PCB fabrication, assembly, prototype manufacture, production test, and design transfer.
Familiarity with requirements-management, product-lifecycle-management, or issue-tracking tools.

Level Expectations

Mid-Level Electronics Engineer

A mid-level engineer will be expected to independently complete defined PCBA designs from approved architecture and requirements, including schematic capture, PCB layout, bring-up, debugging, and verification. They may require guidance on more complex technical decisions, risk assessments, or cross-system trade-offs.

Senior Electronics Engineer

A senior engineer will be expected to independently deliver complex PCBAs with limited supervision, resolve difficult technical issues, contribute strongly to design reviews and risk-management activities, and provide technical guidance to less-experienced engineers. The role remains part of a team led by senior technical staff and does not carry primary responsibility for overall system architecture.

Personal Attributes

Practical, hands-on, and comfortable working directly with hardware.
Able to translate established architectures and requirements into reliable detailed designs.
Takes ownership of assigned designs through implementation, testing, and verification.
Works methodically and maintains high-quality design documentation.
