Principal Software Engineer - Core Infrastructure (Python/C++) at MED Medtronic Inc — Newton, MA
Full job description
A Day in the Life
As a Principal Software Engineer - Core Infrastructure (Python/C++) you will set the technical direction for the core infrastructure that the Prism Mapping platform runs on — the foundation beneath every clinical workflow, every map, and every UI surface. You'll lead architecture for cross-cutting concerns: real-time data movement, device communications, service composition, and system reliability under clinical conditions. You'll work closely with senior engineering leaders, hardware architects, systems engineering, and quality to shape multi-release roadmaps; mentor senior and principal engineers across teams; and raise the engineering bar for how foundational software is built in a medical device environment. The decisions you make here will be felt by every other engineer on the team — and, ultimately, by every physician using the system.
About the Affera Prism Mapping System
Primary Responsibilities
- Lead architecture for the Prism Mapping platform's foundational software — runtime, IPC, device communication, system services, and the operational backbone of a medical device.
- Define multi-release direction for how the platform scales with new clinical capabilities, new hardware, and evolving regulatory expectations.
- Set the engineering bar for infrastructure code on reliability, observability, performance, and safety.
- Lead the design and delivery of major subsystems, cross-cutting architecture, or large technical initiatives.
- Exercise broad technical judgment in defining approaches to complex system and architectural problems with limited oversight.
- Drive technical alignment across software, systems, quality, product, and other cross-functional teams.
- Establish and promote software design patterns, engineering standards, and development best practices.
- Provide technical leadership across teams through mentoring, design reviews, and guidance on critical engineering decisions.
- Identify and drive improvements in architecture, development processes, and system design.
- Shape the technical roadmap and architectural direction for major subsystems or product capabilities.
- Communicate complex technical tradeoffs, risks, and recommendations to stakeholders across functions.
Required Qualifications
- Bachelor's degree and a minimum of 7 years of relevant experience
- OR Master’s degree with a minimum of 5 years of relevant experience
- OR PhD with 3 years relevant experience
Preferred Qualifications
- Deep expertise in Linux systems programming, real-time/near-real-time architecture, and device-connected systems.
- Track record of architecting platform-level software that other teams build on.
- Deep expertise in Python and C++ and in software architecture for complex, multi-component systems.
- Proven experience delivering complex, real-time, device-integrated, or networked systems.
- Experience leading large, complex, cross-functional technical initiatives.
- Experience defining architecture, standards, or technical direction across multiple components or teams.
- Experience solving ambiguous, high-impact technical problems spanning multiple domains or subsystems.
- Experience influencing technical decisions beyond immediate team boundaries.
- Experience in regulated environments preferred.
- Advances how the team uses AI tools — introduces new approaches that raise team productivity and quality.
