Senior Software Engineer 
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

The second Senior Software Engineer joins the growing software team to build out the application and cloud-facing software layer of the Axana platform. Working alongside the first Senior Software Engineer and the Software Lead, this role develops software systems that connect the clinical device to data storage, processing pipelines, and the broader product infrastructure. Employment type will be confirmed based on funding position and roadmap at time of hire.

What Success Looks Like
  •  Axana data pipeline is reliable, auditable, and supporting active clinical data collection

  • Backend services handle the full data lifecycle from device capture to analysis-ready export

  • Software is well-tested and maintainable — adding features does not introduce regressions

  • Regulatory-relevant documentation is complete, current, and accessible for audit

Soft Skills Requirements
  • Strong problem-solving and analytical skills

  • Ability to work independently and as part of a team

  • Good communication and collaboration skills

  • Willingness to learn and continuously develop technical expertise

  • Professionalism, reliability, and attention to detail
