Lead Mechanical Engineer

Lyntris is a defense technology company that connects sensing to action across the connected battlespace. Lyntris brings together the talents of Accelint and Vitesse teams under one mission, with each contributing deep expertise within their domain. Combining differentiated hardware, software and mission expertise, Lyntris helps customers sense threats, make sense of complex conditions and act with greater speed, precision and confidence in contested environments.

Lyntris supports U.S. and allied defense organizations across every branch — including Navy, Army, Air Force, Space Force and allied partners — spanning strategic, operational and tactical missions and every domain:
Space, Air, Land, Sea and Cyber. With more than 200 active defense programs, Lyntris works at every level of the mission, from national command authority to the tactical edge.

Solutions are designed by operators who understand the mission, engineered for the conditions that degrade or defeat standard systems, and built on an open, modular architecture that integrates into existing programs without requiring them to start over. Lyntris moves faster than the traditional defense cycle — with integrated design, build and test capabilities in-house — and delivers systems that sustain and endure long after initial fielding.

• Full Time
• Hybrid / Onsite

The Senior Mechanical Engineer will serve as a senior technical leader and mechanical engineering subject matter expert supporting the research, design, development, integration, and demonstration of advanced defense sensor and mission systems across Lyntris’ portfolio. This role will work closely with engineering leadership, internal multidisciplinary teams, external design partners, subcontractors, suppliers, and government stakeholders to develop practical, mission-focused hardware solutions.

This individual will play a critical role in the technical oversight, implementation, and maturation of mechanical subsystems across structural, thermal, packaging, manufacturability, integration, environmental performance, and production-readiness domains. The ideal candidate is an experienced mechanical engineering leader who can act as a technical authority for major hardware development efforts, guide architecture and design trades, evaluate subcontractor designs and deliverables, mentor engineering personnel, support proposal and customer engagement activities, and help scale Lyntris’ internal design, development, test, and production-transition capabilities.

• Serve as a mechanical engineering subject matter expert responsible for guiding technical approaches, assessing design maturity, and ensuring mechanical solutions align with system-level performance, environmental, producibility, and mission requirements.
• Develop, review, and mature mechanical architectures, subsystem designs, packaging concepts, interface definitions, and integration approaches aligned to system and mission requirements.
• Recommend and articulate hardware and system design approaches using current and next-generation components, materials, manufacturing methods, and technologies.
• Support structural, thermal, environmental, producibility, maintainability, survivability, and design-for-manufacturing trade studies across complex hardware and integrated system efforts.

• Provide technical oversight of subcontractor and supplier mechanical engineering activities, including design concepts, analyses, CAD models, drawings, interface control documents, test plans, and delivered hardware.
• Review subcontractor technical data packages, drawings, analyses, manufacturing plans,…
