This opportunity resides with
Warfare Systems (WS), a business group within HII's Mission Technologies division. Warfare Systems comprises cyber and mission IT; electronic warfare; and C5ISR systems.
Job DescriptionMission Technologies, a division of HII, is expanding - and we're looking for bold, inventive
Prinicipal Mechanical Engineers 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.
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
Minimum QualificationsLevel Requirements: - Level 5: 15 years relevant experience with Bachelors in related field; 13 years relevant experience with Masters in related field; or 10 years relevant experience with PhD or Juris Doctorate in related field.
Clearance Requirement:- Active US Secret clearance required, with ability to obtain TS/SCI.
Technical Requirements: - Experience with mechanical CAD tools.
- Proven mechanical design experience (mechanisims, power trains, thermal management, structures, embedded electronics).
- Experience with various manufacturing methods (additive, machining, sheet metal, PCBAs, cable harnesses, composites).
- Hands-on assembly experience.
- Strong documentation skills (2D engineering drawings, PowerPoint, Visio, Adobe suite).
- Creativity and comfort with open-ended, precedent-free problem solving.
Preferred Requirements- Advanced fabrication experience (welding, composite layups, machining, industrial finishes and paints).
- Simple embedded electronics work (Jetson, Arduino, RPi) and associated Python or C++ programming skills.
- Experience using computational fluid dynamics (CFD and/or FEA for stress, deformation, and modal analysis).
- Working knowledge of RF systems (signal analyzers, SDRs, antennas, amplifiers).
- Experience with project management (Earned value mgmt, estimating, requirements capture).
- An active TS/SCI clearance
Physical RequirementsMay require working in an office, industrial, shipboard, or laboratory environment. Capable of climbing ladders and tolerating confined spaces and extreme temperature variances.
