How much do thermo mechanical engineer jobs pay per year?

As of Aug 7, 2026, the average yearly pay for thermo mechanical engineer in the United States is $102,878.00, according to ZipRecruiter salary data. Most workers in this role earn between $81,500.00 and $126,500.00 per year, depending on experience, location, and employer.

What are the key skills and qualifications needed to thrive as a thermo mechanical engineer, and why are they important?

To thrive as a Thermo Mechanical Engineer, you need a solid background in mechanical engineering principles, thermodynamics, heat transfer, and material science, usually supported by a relevant engineering degree. Familiarity with CAD software, finite element analysis (FEA) tools, and industry standards or certifications like PE licensure is often required. Strong problem-solving abilities, attention to detail, and effective teamwork and communication skills help set top performers apart. These skills and qualities are crucial for designing reliable thermal systems, ensuring safety, and successfully collaborating on complex engineering projects.

What is the difference between Thermo Mechanical Engineer vs Mechanical Engineer?

AspectThermo Mechanical EngineerMechanical Engineer
Required CredentialsBachelor's or Master's in Mechanical Engineering, specialization in thermodynamics or heat transferBachelor's or Master's in Mechanical Engineering
Work EnvironmentDesign, analyze, and optimize thermal systems like HVAC, engines, or turbinesDesign and develop mechanical systems across various industries
Industry UsageEnergy, aerospace, automotive, HVACManufacturing, automotive, aerospace, consumer products

Thermo Mechanical Engineers focus on thermal systems and heat transfer, while Mechanical Engineers have a broader scope in mechanical design and development. Both roles require similar educational backgrounds but differ in specialization and application areas.

What are some common challenges faced by thermo mechanical engineers when working on multidisciplinary projects?

Thermo Mechanical Engineers often collaborate with teams spanning electrical, materials, and systems engineering. One common challenge is aligning thermal management solutions with mechanical constraints while ensuring compatibility with electronics and structural requirements. This often requires clear communication, iterative design adjustments, and a strong understanding of how thermal and mechanical factors interact. Staying up to date with simulation tools and industry standards is also crucial for effective problem-solving and project integration.

What is a thermo mechanical engineer?

Thermo Mechanical Engineers are professionals who specialize in the study and application of the relationships between thermal (heat) and mechanical (force, motion) processes in materials and systems. They work on designing, analyzing, and improving systems where temperature changes and mechanical forces interact, such as engines, turbines, HVAC systems, and electronic devices. Their work often involves simulations, testing, and selecting materials that can withstand specific thermal and mechanical stresses. Thermo Mechanical Engineers play crucial roles in industries like aerospace, automotive, energy, and manufacturing. They help ensure products are safe, efficient, and reliable under varying thermal and mechanical conditions.

Job description

About the role
Own the thermo-mechanical design of the advanced packages our AI accelerator silicon ships in. A multi-die 2.5D package is a stack of materials that all want to expand at different rates, under a lid, under load, cycling through hundreds of watts - and your job is to make it stay flat, stay bonded, and stay intact. You'll model warpage and stress through reflow and assembly, design the lid, stiffener, underfill and TIM stack that controls them, set the mechanical rules our OSATs build to, and own the socket and load mechanics where the package meets the cooling solution. You'll correlate every model against real measurement, and you'll be the person who knows whether a design will survive the assembly line before it gets there.
What will you do
  • Own thermo-mechanical modeling and FEA for multi-die packages; warpage across reflow and assembly, die and interconnect stress, CTE mismatch, and structural response under thermal and mechanical load
  • Own package mechanical design; lid and heat spreader, stiffener, underfill and mold compound selection, and TIM specification and bondline control at the package-to-cooling interface
  • Drive assembly process mechanics and mechanical design rules with OSATs and substrate suppliers, and own socket and load-frame mechanics for high-force accelerator sockets
  • Correlate models to measurement (shadow moire, strain gauge, DIC) and drive DOEs that close the gap between simulation and silicon
  • Use and develop AI assisted tool flows to accelerate mechanical modeling and signoff timelines
What we're looking for
  • Exceptional abilities in thermo-mechanical analysis of semiconductor packages: warpage prediction and control, die and solder-joint stress, delamination and interfacial fracture risk, and material and structural tradeoffs
  • 8+ years of packaging mechanical experience on high-performance designs, including 2.5D / 3D and multi-die packages (CoWoS, EMIB, InFO, fan-out, or equivalent) and HBM-bearing assemblies
  • Hands-on with industry-standard FEA tools (Ansys Mechanical, Abaqus, or equivalent) and strong materials knowledge across underfills, mold compounds, substrates, TIMs, and lid materials
  • Demonstrated ability to work closely with packaging, thermal, reliability, board, and OSAT partners to converge mechanical designs and sign them off against JEDEC and IPC standards

Full compensation packages are based on candidate experience and relevant certifications.
California pay range
$200,000-$275,000 USD
Compensation
Final offers depend on level, location, and skills relevant to the role. Additional compensation: equity grant per company guidelines; medical / dental / vision; 401(k); standard PTO.
Visa Sponsorship
DensityAI sponsors qualified candidates for H-1B, O-1, TN, E-3, and other employment-based visas, and we welcome applicants on F-1 OPT and STEM-OPT. Work authorization is required at start; we provide immigration support to secure or transfer status.
Export Controls
Aspects of this role may involve access to information subject to U.S. export controls (EAR/ITAR). We may discuss licensing or scope adjustments during the interview.
Equal Opportunity
DensityAI is an Equal Opportunity Employer. We do not discriminate on the basis of race, color, religious creed, national origin, ancestry, physical or mental disability, medical condition, genetic information, marital status, sex, gender, gender identity, gender expression, age (40+), sexual orientation, military or veteran status, pregnancy, or any other status protected by law.
