About Cathflow Medical

At Cathflow, we are on a mission to transform interventional cardiology with the next generation of MedTech solutions. By combining advanced imaging, clinically validated algorithms, and intuitive workflows, we empower cardiologists to make faster, better-informed treatment decisions—directly improving patient health and reducing the burden of coronary artery disease. As an early-stage start-up, we offer the opportunity to shape a category-defining product, work alongside world-class clinical and technical leaders, and see your work make a measurable impact in hospitals.

About the Role

We are looking for a strong, hands-on Senior Software Developer to join our team and hit the ground running. If you are passionate about building robust, scalable systems that have a real-world impact on patient health, we want to talk to you.

What You'll Do

As a core member of our development team, you will be instrumental in building the software that powers our innovative medical device. You will:

• Architect and Develop:
  Design, build, and maintain scalable, high-performance backend services and APIs using Python.
• Own the Pipeline:
  Implement and manage our CI/CD pipelines, ensuring smooth, automated, and reliable deployments. You'll be a key driver of our DevOps culture, focusing on infrastructure as code (IaC), containerization (Docker, Kubernetes), and cloud infrastructure.
• Ensure Quality:
  Write clean, maintainable, and well-tested code. You will champion best practices and collaborate on code reviews to maintain the highest standards, which are critical in the medical device space.
• Collaborate & Innovate:
  Work closely with a cross-functional team of engineers, product managers, and clinical experts to translate complex requirements into elegant technical solutions.
• Bridge the Gap (Bonus):
  If you have front-end skills, you may contribute to building intuitive user interfaces that our clinical users will love.

What You'll Bring

• Senior-Level Python Expertise:
  You have extensive professional experience building complex applications with Python and its ecosystem (e.g., FastAPI, Django, Flask).
• Strong Backend Foundation:
  Deep understanding of API design (REST, GraphQL), microservices architecture, and experience with relational and NoSQL databases (e.g., PostgreSQL, MongoDB).
• DevOps Mindset:
  Proven experience with CI/CD tools (e.g., Jenkins, GitLab CI, GitHub Actions), containerization with
  Docker
  and orchestration with
  Kubernetes
  , and cloud platforms (
  AWS, GCP, or Azure
  ).
• Problem-Solving Skills:
  An ability to tackle complex technical challenges independently and a drive to find the best possible solution.
• Team Player:
  Excellent communication skills and a collaborative spirit. You thrive in a fast-paced environment where you can both lead and learn.

Huge Pluses

• Front-End Experience:
  Proficiency with a modern JavaScript framework like
  React, Vue, or Angular
  .
• Healthcare/MedTech Background:
  Previous experience working on medical devices, in a regulated environment (e.g., ISO 13485, IEC 62304), or with healthcare data standards (e.g., DICOM, HL7) is a massive advantage.

Why Join Us?

• Make a Real Impact:
  Build a product that will directly improve the lives of cardiology patients and the clinicians who care for them.
• Work with the Best:
  Join a team of A-players and collaborate with world-renowned experts in the medical and technical fields.
• Build from the Ground Up:
  This is a unique opportunity to shape the architecture and technology of a groundbreaking product from its early stages.
• Dynamic & Ambitious Culture:
  We are a results-oriented team with a passion for excellence and a desire to move fast.
