What does a mechanical systems design engineer do?

A Mechanical Systems Design Engineer is responsible for designing, developing, and testing mechanical systems and components for various applications, such as automotive, aerospace, or manufacturing industries. Their tasks often include creating detailed drawings and specifications, performing engineering analyses, and collaborating with other engineers to ensure systems meet performance and safety standards. They also play a key role in troubleshooting issues, improving existing designs, and ensuring compliance with industry regulations. This role requires strong problem-solving skills and proficiency in computer-aided design (CAD) software.

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

To thrive as a Mechanical Systems Design Engineer, you need a solid background in mechanical engineering principles, proficiency in CAD software, and typically a bachelor's degree in mechanical engineering or a related field. Familiarity with industry-standard tools like SolidWorks, AutoCAD, and simulation software, as well as knowledge of relevant codes and standards, is essential. Strong problem-solving abilities, attention to detail, and effective communication skills help you excel in collaborating with multidisciplinary teams and addressing complex design challenges. These skills ensure the development of safe, efficient, and innovative mechanical systems that meet project requirements and industry standards.

What are some typical challenges faced by mechanical systems design engineers during project development?

Mechanical Systems Design Engineers often encounter challenges such as balancing innovative design with cost and manufacturability, ensuring compliance with industry standards, and integrating mechanical systems within multidisciplinary teams. Additionally, they may need to troubleshoot unforeseen performance issues during prototyping and adapt to evolving client requirements. Effective communication and collaboration with electrical engineers, manufacturers, and project managers are essential to successfully deliver complex projects on time.

What is the difference between Mechanical Systems Design Engineer vs Mechanical Design Engineer?

AspectMechanical Systems Design EngineerMechanical Design Engineer
CredentialsBachelor's in Mechanical Engineering; possibly PE licenseBachelor's in Mechanical Engineering; possibly PE license
Work EnvironmentDesigning complex mechanical systems in manufacturing, automotive, or aerospaceCreating components and parts for various mechanical products
Industry UsageUsed in industries requiring integrated system designCommon in product development and component design

Both roles require a mechanical engineering background and similar certifications. The Mechanical Systems Design Engineer focuses on designing complete mechanical systems, often involving integration and system-level considerations, while the Mechanical Design Engineer concentrates on individual components and parts. The choice depends on whether the role emphasizes system-level integration or component-level design.

Job description

Job Summary

Deep Fission is seeking a Mechanical Systems Design Engineer to support the engineering and design of surface mechanical systems for the reactor pilot project. This person will contribute to the design for standard nuclear mechanical systems such as the chemical volume control system, secondary coolant system, and balance of plant systems.

The ideal candidate will bring expertise in mechanical-fluidic system design, nuclear systems, construction, interdisciplinary interface and technical subcontract management. This role requires comfort operating in first-of-a-kind environments where precedent is limited, requirements evolve, and creative problem-solving is essential. The Mechanical Systems Design Engineer will support alignment between multiple engineering disciplines, construction, procurement, and licensing.

Key Responsibilities:

  • Perform mechanical system engineering tasks for the development of Deep Fission's surface facilities - from conceptual development through licensing, fabrication, construction, startup, and turnover.
  • Coordinates or prepares diagrams, specifications, procurement documents, and award recommendations.
  • Ensure effective coordination with the other engineering disciplines to maintain alignment on technical scope.
  • Advance designs rapidly in a dynamic environment, applying sound engineering judgment and calculated risk management.
  • Support interface activities between partner organizations and major subcontractors, participating in face-to-face events to create effective work and decision-making environments.
  • Contribute to general design coordination events such as mechanical system design reviews and in-person design workshops.
  • Promote a proactive nuclear safety culture across office and field-based activities.
  • Advocate for the Deep Fission company and its technology.
  • Participate in project planning (schedule and budgeting) and be prepared to commit to delivery against the project plan.
  • Provides assistance toproject and construction management for mechanical system requirements, identifying issues as they arise during project execution.

Required Skills & Experience:

  • 5+ years of experience in the relevant engineering discipline, including successful delivery of mechanical system designs.
  • Background in regulated environments such as nuclear, aerospace, defense, utility or industrial capital projects.
  • Bachelor's degree in Engineering or related technical field with a deep understanding of engineering fundamentals and modern design practices.
  • Understanding of nuclear QA programs (e.g., NQA-1), and compliance documentation.
  • Ability to perform in a design role supporting large design efforts with multiple interfaces and stakeholders.
  • Ability to maintain communication and stakeholder engagement in a virtual and hybrid team environment.
  • Ability to travel - candidate will be required to travel on a moderate basis depending on the project phase up to 20%
  • Must be a U.S. person eligible to meet DOE Export Control requirements under 10 CFR 810.

Desired Skills & Experience:

  • Licensed Professional Engineer (PE) or pursuing professional registration is a plus
  • Experience with SMRs, Gen IV technologies, or first-of-a-kind nuclear reactor development.
  • Demonstrated experience navigating NRC or DOE regulations. Strong understanding of nuclear QA programs (e.g., NQA-1), and compliance documentation.
  • Background in nuclear construction, site development, or commissioning of safety-related systems.
  • Proficiency with engineering software tools, AI-enabled platforms.

Key Competencies:

  • Design Acumen - Ability to make assumptions and establish design concepts based on wisdom gained from experience and education.
  • Organizational - Experience on structured engineering teams functioning with other engineering disciplines, and subcontractors to support project objectives.
  • Adaptability/Resilience - the capacity to adjust actions, strategies, and behaviors in response to unexpected or ambiguous situations, learning and pivoting quickly.
  • Decision-Making - Balances technical rigor with business trade-offs; uses data and judgment effectively.
