Job Description:

We are seeking a highly motivated Mechanical Engineer to join the W76-1 Joint Test Assembly (JTA) Weapon System Team. In this role, you will contribute to the mechanical design, development, and qualification of the new instrumented JTA flight test body for the W76-1 weapon systems. You will engage in a diverse range of engineering activities, including assembling system-level assets, coordinating and planning tests, managing product definition and documentation flow, integrating systems, supporting production, and interfacing with design teams. Your work will involve close collaboration with internal Sandia teams as well as external partners at LANL, KCNSC, Pantex, NNSA, and Navy SP-28. As a successful candidate, you will gain intimate knowledge of the detailed function of W76-1 nuclear weapon components, subsystems, and systems. You will also develop a broad understanding of the entire product realization lifecycle from concept exploration and design through development, qualification, production, and sustainment.

Job Responsibility:

  • Develop a detailed understanding of customer requirements and support their maturation and translation into system-level configurations
  • Assemble and integrate mechanical, system, and subsystem assemblies
  • Integrate and test subassemblies and system configurations

  • Analyze system-level test data and support anomaly resolution with critical thinking and problem-solving
  • Manage product definition, release documentation created by design teams, and ensure proper authorization and distribution through Sandia's drawing and authorization systems

Requirements:

  • A bachelor's degree in a relevant discipline, or an equivalent combination of directly relevant education and engineering or scientific experience that demonstrates the knowledge, skills, and ability to perform independent research and development
  • Active DOE Q Clearance or equivalent is required to start

Nice to have:

  • Graduate degree in Mechanical Engineering or a highly related field where an independent research project was a graduation requirement (e.g., independent project, thesis, or dissertation)
  • Experience with mechanical engineering and product realization in the NNSA complex
  • Strong verbal and written communication skills and ability to work effectively in multidisciplinary teams
  • Self-motivated, positive individual comfortable working in a fast-paced environment and collaborating effectively across multiple technical teams and management
  • Experience applying engineering principles to conduct trade studies and identify system solutions
  • Previous experience with JTA development programs and a solid background in nuclear weapons lifecycle and Nuclear Security Enterprise (NSE) processes
  • Proficient in test instrumentation, test planning, defining test objectives and methods, and building test bodies or developing procedures for test artifact fabrication
  • Familiarity with Sandia Mechanical test facilities (e.g., Shock/Vibe Lab, Centrifuge Facility) and experience coordinating testing activities
  • Knowledge of Sandia's drawing and authorization systems, product development and qualification processes, testing and evaluation, as well as modeling and simulation
  • Skilled in mechanical design tools such as CREO
  • Experience working with NNSA, Department of Defense customers and contractors, Los Alamos National Laboratory, Kansas City National Security Campus (KCNSC), and Pantex
What we offer:
  • Challenging work with amazing impact
  • Extraordinary co-workers
  • Some of the best tools, equipment, and research facilities in the world
  • Career advancement and enrichment opportunities
  • Flexible work arrangements for many positions include 9/80 (work 80 hours every two weeks, with every other Friday off) and 4/10 (work 4 ten-hour days each week) compressed workweeks, part-time work, and telecommuting (a mix of onsite work and working from home)
  • Generous vacation
  • Strong medical and other benefits
  • Competitive 401k
  • Learning opportunities
  • Relocation assistance
  • Amenities aimed at creating a solid work/life balance
