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

To thrive as a Mechanical Engineer, you need a solid background in mechanical design, mathematics, and physics, typically supported by a bachelor's degree in mechanical engineering or a related field. Proficiency in CAD software (such as SolidWorks or AutoCAD), finite element analysis tools, and familiarity with industry standards or relevant certifications (like a Professional Engineer license) are common requirements. Strong problem-solving abilities, teamwork, and effective communication skills help professionals excel in collaborative and multidisciplinary environments. These skills are crucial for ensuring safe, innovative, and efficient engineering solutions that meet project and client needs.

What are common interdisciplinary collaborations for mechanical engineers in a typical project setting?

Mechanical Engineers often work closely with professionals from other disciplines such as electrical engineers, software developers, and industrial designers, especially when developing complex products or machinery. Collaboration is essential for integrating mechanical systems with electronics and software, ensuring functionality, safety, and efficiency. These interactions usually involve regular team meetings, joint problem-solving sessions, and coordinated testing to achieve project goals. Being comfortable working in cross-functional teams can significantly enhance your success and contribute to innovative solutions.

What is the difference between Mechanical Engineer vs Mechanical Designer?

AspectMechanical EngineerMechanical Designer
Required CredentialsBachelor's degree in Mechanical Engineering, PE license (optional)Bachelor's degree in Mechanical Design, CAD certifications (often)
Work EnvironmentDesign, analysis, testing, project managementCreating detailed CAD models, drafting, and design documentation
Industry UsageEngineering firms, manufacturing, aerospace, automotiveProduct design, manufacturing, industrial equipment

Mechanical Engineers focus on designing, analyzing, and testing mechanical systems, often overseeing projects from conception to completion. Mechanical Designers primarily create detailed CAD models and drawings based on specifications. While both roles require technical skills and knowledge of mechanical systems, Mechanical Engineers typically have broader responsibilities including analysis and project management, whereas Mechanical Designers specialize in detailed design work.

What does a mechanical engineer do?

A Mechanical Engineer designs, develops, builds, and tests mechanical devices such as engines, machines, and tools. They use principles of physics and mathematics to solve engineering problems and improve existing products. Mechanical Engineers can work in a variety of industries, including automotive, aerospace, manufacturing, and energy. Their responsibilities often include creating blueprints, analyzing data, and collaborating with other engineers or professionals to ensure projects meet safety and quality standards.

Full-time

Re-posted 12 days ago

Job description

Diamond Foundry Inc. is solving the thermal limitation at the foundation of today's most exciting tech industries -- AI & cloud compute, electric-car power electronics, and 5G/6G wireless. We have managed to produce the world's first single-crystal diamond wafers and are now on a mission to put a diamond behind every chip. We are the rare unicorn that has grown fast and profitably. We received $515m in funding and are executing a multi-$B expansion plan for one of the greenest forms of tech manufacturing: converting greenhouse gas into diamond wafers using zero-emission energy.

We are seeking an on-site R&D Test Engineer to join our AI Chips team. This role will work closely with the thermal/mechanical/reliability lead to execute thermal testing, coordinate reliability testing, design and develop custom test hardware and fixtures for customer prototyping of single-crystal diamond applications on AI customer chips, and generate engineering insights that guide customer engagements and product development. 

The ideal candidate is a hands-on thermal or mechanical engineer with strong technical problem-solving skills, a collaborative mindset, and the ability to support fast-paced customer and internal development programs.

This position will be located out of our San Jose office. 
Responsibilities

  • Support customer prototyping projects through design and development of mechanical fixtures and experimental apparatus using CAD software, and coordinate fabrication with internal and external machine shops.

  • Coordinate accelerated lifetime reliability testing and environmental stress testing per industry standards to validate long-term performance and durability of SCD-on-silicon attachment methods, package integrity.

  • Design, build, operate, and troubleshoot thermal characterization test platforms to evaluate SCD thermal solutions on thermal test vehicles (TTVs) and customer hardware.

  • Develop assembly processes for prototype hardware, including thermal interfaces, mounted cooling solutions, and instrumentation integration as needed.

  • Manage project schedules, technical risks, cross-functional communication, customer updates, and technical reports.

Requirements

  • Degree & Experience: BS or MS in Mechanical Engineering or a related discipline, with 2+ years of experience in mechanical/thermal engineering, test engineering, or product development.

  • Thermal & Reliability Testing: Experience with laboratory instrumentation and data acquisition systems (Preferred: thermal testing/characterization for packaged devices, liquid cooling solutions like fans/cold plates, and reliability/environmental stress testing).

  • Software & Simulation: Proficiency with CAD software (SolidWorks preferred) (Preferred: familiarity with FEA and CFD tools such as ANSYS Mechanical/Fluent, Icepak, or COMSOL).

  • Data Analysis & Fabrication: Experience creating engineering drawings to support fabrication, alongside data processing and analysis using MATLAB, Python, Excel, JMP, or similar tools (Preferred: familiarity with IC packaging, metrology, or failure analysis).

  • Professional Attributes: Strong problem-solving and communication skills, with a hands-on, detail-oriented mindset, comfortable working cross-functionally in a fast-paced R&D environment.

The position is eligible for company shares. Actual compensation may be higher or lower in the range based on various factors, including, but not limited to a candidate’s job duties, experience, and location. We will also consider higher-level candidates and salary will be adjusted accordingly.
