Senior Mechanical Engineer, Thermal Analysis

We are looking for a Senior Thermal Analyst to join our rapidly growing team in Lexington, MA. In this role, you will be responsible for performing thermal analysis and taking ownership of thermal design aspects across hardware development programs. You will execute first order assessment of designs to guide preliminary design architecture, develop detailed analytical models to mature prototype designs and develop predictions to support hardware testing.

If you are someone who is excited to work on new projects from conceptualization through production and are passionate about developing validated and correlated models to support the rapid prototyping of cutting edge systems.

- Execute hand calculations, spreadsheet, and MATLAB/Python first-order models to inform path forward before jumping into detailed analysis. Use first principles as a basis for every decision and discern the right level of analysis to apply based on state of hardware design and program goals

- Develop appropriate CFD models and simulations to predict temperatures, heat transfer, and fluid characteristics as needed to meet design schedules. Generate, maintain, and correlate integrated FEMs for imaging platforms.

- Perform test-model correlation testing to validate analytical predictions

- Work closely with environmental test engineers to support the design, instrumentation selection, execution, and data processing of tests to validate models and predictions, including fundamental

- Prepare technical reports to present findings to internal teams, management, and external customers

- Stay current with advancements in thermal analysis techniques, materials technology, and industry standards

- Currently pursuing or have obtained a MS or higher degree in engineering or applied physics with focus on heat transfer and fluid dynamics

- 7+ years of experience in a thermal analysis or thermo-physics analysis role

- Thermal FEA experience - STAR-CCM+, ANSYS, Icepak, or Flotherm

- Familiarity with Matlab or Python (or equivalent) for developing analytical models and performing data acquisition & post-processing

- Experience with performing test-model correlation and test based characterization of critical modelling input parameters

- Good at working independently and with various teams and key stakeholders

- Highly motivated, self-starting, results oriented, and capable of working in a dynamic environment

- Eligible to obtain and maintain an active U.S. Secret security clearance

- Performed structural, thermal, and optical performance (STOP) models for high performance imaging systems

- General knowledge of climatic and/or dynamic testing including understanding of various instrumentation and data acquisition fundamentals

- Knowledge on how to run and operate chambers, DAQs, and other major test apparatus

- CAD skills (any platform) and ability to make high quality engineering drawings that meet common industry standards

- Experience in an immersive interdisciplinary technical project (collegiate project teams or professional settings)
