About the role

The future of aerospace and defense starts here.

Ursa Major was founded to revolutionize how America and its allies access and apply high-performance propulsion, from hypersonics to solid rocket motors, satellite maneuvering and launch. We design and deliver propulsion and defense systems that solve the most urgent and critical national security demands.

The Design Engineer II, Solid Missile Systems, is responsible for the design, analysis, and qualification of solid rocket motor primary structures as well as secondary structures and propulsion elements based on customer requirements and industry specifications. Since Ursa Major leverages additive manufacturing to a significant degree, experience with metal additive design and emerging technologies is required. Additionally, experience designing for high-rate production, automation, and reduced touch labor is essential to scalability.

Responsibilities

  • Clean sheet design of novel solid rocket motors with limited guidance from subject matter experts.
  • Distill customer requirements into a design that meets or exceeds the intent while adhering to the Ursa Major criteria for low-cost yet reliable products. Also, support customer interactions when requested.
  • Lead development campaigns to prove conceptual designs and evaluate applicability to realized products.
  • Provide guidance on assembly and testing of initial prototypes and troubleshoot as required.
  • Review test data to ensure the product is operating as expected and support design changes as needed.
  • Lead cross-functional communications to ensure designs satisfy the needs of each stakeholder.
  • Develop and maintain aggressive but achievable product schedules that proactively identify and mitigate high-risk design decisions.
  • Generate, review, and approve CAD models and drawings that are consistent with internal best practices and ASME Y14.5-2009
  • Provide dispositions for discrepant hardware including supporting analysis if required.
  • Maintain proper documentation of all designs including design reviews, test plans, requirements verification, customer documentation, etc.
  • Work with the procurement team to ensure the supply chain can support anticipated production rates and adjust designs when significant supply chain risks are identified.
  • Technical mentor for less senior members of the team.
  • Author guidance on design best practices and supporting formal documentation as required.

Required Qualifications

  • Bachelor's degree in aerospace engineering, mechanical engineering, or a related field with 2+ years of relevant experience.
  • Relevant experience with rocket motors, solid propulsion elements, and structural interfaces.
  • Proficiency with computer-aided design and analysis tools.
  • Strong understanding of design for additive manufacturing including material and design limitations of metal additive processes.
  • Strong engineering fundamentals including in-depth knowledge of thermodynamics, fluid dynamics, and structural mechanics.
  • Effective communication skills are crucial for collaborating with cross-functional teams, presenting design concepts, and documenting work.
  • An understanding of insensitive munitions protocols and practices utilized in the design of solid rocket motors.
  • This position requires that the employee be eligible and maintain eligibility for a Secret Clearance.

Desired Experience

  • Master’s degree or PhD in in a technical discipline such as mechanical or aerospace engineering.
  • Experience conducting insensitive munitions testing and product qualification.
  • Hands-on experience supporting rapid product development.
  • Experience designing hardware for high-rate production including automated processes.
  • Familiarity with composite overwrap and filament winding design and analysis.
  • Experience with Siemen’s NX and Ansys software packages.
  • DoD Secret Security Clearance or higher.
