Mechanical Engineer - Multiple Levels (Engineer Mechanical) - 29 Jobs

Mechanical Engineer

Mission Technologies, a division of HII, is expanding - and we're looking for bold, inventive Mechanical Engineers (multiple levels) to join our fast-moving, interdisciplinary teams in our Alexandria, VA. At Mission Technologies, we design and build customized, mission-enabling solutions for the defense and intelligence communities-solutions that fuse cutting-edge technology with real-world tradecraft. Our teams are filled with imaginative builders, hands-on problem solvers, and curious minds from a wide range of backgrounds.

Here, collaboration isn't just a value-it's the way the work gets done. You'll be part of small, high-trust teams that turn ideas into functional hardware at remarkable speed. If you love tackling open-ended problems, experimenting with new technologies, and seeing your designs come to life in the field, this is the place for you. Bring your mechanical engineering expertise-and shape the role based on your strengths, interests, and creativity.

You'll work on rapid-turn projects that go from concept to deployment, contributing to hardware used by end-users around the world.

Your impact will include:

• Hands-On Design & Prototyping:
  Apply your mechanical engineer fundamentals to a diverse, mission-critical projects. This includes developing solutions like electromechanical devices, motion platforms, electronics packaging, and multi-spectral signature management (visible, NIR, thermal, acoustic, RF).
• DFM Focus:
  Leverage your understanding of Design for Manufacturing (DFM) to ensure your designs are optimized for both subtractive and additive manufacturing methods.
• Cross-Functional Collaboration:
  
  Work shoulder-to-shoulder with senior engineers, technicians, managers, and end-user clients in small, close-knit teams. Clear communication and adaptability are key as you iterate quickly within small, agile teams.
• System Integration:
  Use your awareness of electrical systems to ensure all mechanical designs integrate seamlessly into complete products.

Joining HII means joining a team with decades of proven impact:

• Impactful Work:
  Earn a sense of accomplishment by making meaningful contributions to our nation's top security priorities.
• Rapid Prototyping:
  Access to some of the most comprehensive secure rapid prototyping facilities in the mid-Atlantic region, including a full in-house machine shop, composite fabrication, finishing, electronics assembly, and testing capabilities.

Salary range is based on the appropriate level. Essential Job Responsibilities

• Provide support to the design, development, prototype fabrication, and verification testing of unique specialty products
• Perform detailed system and sub-system analysis, simulation, and design work as required
• Work with complicated mechanical system concepts and detailed designs to properly determine the necessary design tradeoffs
• Interface with project teams and external customers as required, to support specialized product development
• Participate in the assembly, system test planning, and system test procedure generation
• Adequately document processes, procedures, and testing using structured formats. Where formats do not currently exists, provide a recommended format for review
• Learn and utilize the Quality Management System (QMS) and existing tools and templates
• Interface with project teams and external customers as required, to support specialized product development
