Job Description
The Senior Mechanical Engineer – Fluids & Thermal Analysis will play a critical role within the R&D organization, focusing on the analysis, modeling, and optimization of fluidic and thermal performance in complex medical devices and combination products. This role will support product development from early concept development through verification, validation, and manufacturing transfer by applying engineering analysis and computational modeling techniques.
Job requirements
- BS in Mechanical Engineering or related discipline (MS or PhD preferred, with emphasis on fluid mechanics or heat transfer).
- 5 years of relevant industry experience, preferably in medical devices or other regulated, high‑reliability industries.
- Strong foundation in fluid mechanics, heat transfer, and thermodynamics, with demonstrated application to real‑world engineering problems.
- Proven experience with CFD and thermal simulation tools (e.g., Ansys Fluent/CFX, COMSOL, Star‑CCM , or equivalent).
- Experience developing simplified analytical or reduced‑order models to complement detailed numerical simulations.
- Familiarity with experimental methods for fluid and thermal systems, including test design, instrumentation, and data analysis.
- Experience working within a regulated design environment and applying structured design and documentation practices (e.g., ISO 13485, MDR, AS9100, or similar).
- Ability to work independently, rigorously analyze data, and communicate complex technical concepts clearly to cross‑functional audiences.
- Excellent written and verbal communication skills, with the ability to document assumptions, limitations, and conclusions effectively.
Job responsibilities
- Lead the analysis and modeling of fluid flow, heat transfer, and mass transport in complex patient‑connected therapeutic systems, assemblies, and components using analytical methods and simulation tools.
- Develop and execute CFD, thermal, and multiphysics models to predict system behavior, support design decisions, and inform requirements and risk assessments.
- Collaborate closely with mechanical design, electrical, software, systems, and manufacturing engineers to ensure physics‑based performance is fully integrated into the overall product architecture.
- Define, plan, and execute bench‑top and system‑level experiments to validate analytical and computational models, including test method development and data interpretation.
- Support design reviews, phase‑gate reviews, and root‑cause investigations by providing quantitative analysis and clear technical rationale.
- Translate modeling results into actionable design guidance, including performance tradeoffs, sensitivity analyses, and operating envelopes.
- Mentor and provide technical guidance to junior engineers in engineering analysis, modeling best practices, and experimental correlation.
- Manage multiple analysis efforts across projects while balancing technical rigor, timelines, and project priorities.
Job benefits
- Competitive salary and benefits package
- Opportunities for professional development and career growth.
- Collaborative and innovative work environment.
