What Your Job Will Be Like

Join our mission-driven team as an R&D Mechanical Engineer leading the mechanical design of the W93-0/Mk7 weapon system. In this critical and highly visible role, you will apply your technical expertise and strategic leadership to shape advanced weapon system architectures, drive cross-team collaboration, and serve as a trusted advisor to executive management. You will balance hands-on mechanical design with decision-making authority over cost, schedule, and performance, ensuring alignment with program goals and national security objectives.

On any given day, you may be called on to:

• Lead the mechanical design efforts for the W93 system, including developing mechanical layouts that define the position, size, and location of major components and subassemblies within the reentry body.
• Collaborate closely with external partners such as Lockheed Martin and Los Alamos National Laboratory to negotiate requirements, define interfaces, and ensure manufacturability and interface compliance.
• Coordinate with internal teams and specialized subgroups responsible for ancillary parts (e.g., brackets, pads), working alongside electrical engineering leads to ensure seamless physical integration.
• Use tools like Creo and SolidWorks to model concepts and communicate design intent effectively, supporting configuration management workflows with PDMLink to maintain design integrity.
• Manage system-level risk assessment and lead cross-team coordination to drive initiatives and meet program objectives.
• Present designs and participate in design reviews with both internal teams and external partners, advocating for sound engineering decisions and system-level thinking.
• Serve as a recognized technical resource and consultant to executive management, providing expert guidance on mechanical design strategies and system integration approaches that impact long-term program success and national security objectives.
• Exercise decision-making authority within organizational parameters related to cost, schedule, and performance for mechanical design activities, ensuring alignment with program goals and resource constraints.
• Provide strategic recommendations to executive leadership on long-term issues affecting the W93 program and broader Sandia initiatives, including risk mitigation, technology development, and cross-organizational collaboration.

This role requires strong leadership skills to drive initiatives, manage cross-team coordination, and balance hands-on mechanical design with strategic systems engineering. Due to the sensitive nature of the work, the selected candidate must be able to work onsite.

About Our Team

The W93 Systems Design Department is composed of both mechanical and electrical engineering staff. We work closely with our external design agency partners, including Los Alamos National Laboratory (LANL) and Lockheed Martin Space (LM Space), as well as our sister organization 2380 (A21/W93 System Engineering and Integration). Together, we are responsible for the integration of the W93-0/Mk7 system. Our team collaborates with numerous internal and external customers to achieve this monumental design objective, striving to ensure the future viability and effectiveness of our nation's nuclear deterrent.

Posting Duration

This posting will be open for application submissions for a minimum of three (3) calendar days, including the 'posting date'. Sandia reserves the right to extend the posting date at any time.

Security Clearance

Position requires a Department of Energy (DOE) Q security clearance to start, or equivalent active security clearance with another U.S. government agency (e.g., DOD). Sandia is required by DOE directive to conduct a pre-employment drug test and background review that includes checks of personal references, credit, law enforcement records, and employment/education verifications. Applicants for employment need to be able to maintain a DOE Q-level security clearance, which requires U.S. citizenship. If you hold more than one citizenship (i.e., of the U.S. and another country), your ability to obtain a security clearance may be impacted.

Applicants offered employment with Sandia are subject to a federal background investigation to meet the requirements for access to classified information or matter if the duties of the position require a DOE security clearance. Substance abuse or illegal drug use, falsification of information, criminal activity, serious misconduct or other indicators of untrustworthiness can cause a clearance to be denied or terminated by DOE, resulting in the inability to perform the duties assigned and subsequent termination of employment.
