Position Overview

Are you ready to move beyond the drafting table and into a role where your designs are physically prototyped, tested, and deployed for missions of national security? We are seeking a Mid-Level Mechanical Engineer to join our Specialized Design team—a high-impact group dedicated to solving the most complex infrastructure challenges for a select group of confidential clients. This isn't just about HVAC load calcs; it’s about "cradle-to-grave" engineering where you take ownership of the entire lifecycle, from initial concept and CFD modeling to hands-on fabrication and field implementation.

Joining our team means stepping into a culture that breathes creativity and values technical integrity above all else. You will work in a fast-paced, broad-spectrum environment where one day involves designing satellite command-and-control cooling systems and the next involves forensic analysis of COTS power systems in a lab setting. For an engineer who craves variety and the satisfaction of knowing their work protects and enriches America’s security, this is the ultimate platform for professional growth and legacy-building.

Core Responsibilities

• End-to-End Design Engineering: Lead and assist in the full design process including HVAC load calculations, system sizing, equipment selection, and the development of 2D/3D CAD drawing packages.

• Technical Innovation & Research: Research cutting-edge HVAC technologies and evaluate mechanical products to meet specialized requirements for feasibility, cost, and maintenance.

• Hands-on Fabrication & Testing: Transition designs from the screen to the shop by implementing hands-on fabrication, designing test control apparatus, and developing procedures for product testing.

• Project Stewardship: Manage discipline budgets and timelines for small-to-medium projects, coordinating seamlessly with internal cross-discipline leads, subcontractors, and vendors.

• Field Engineering & Forensic Analysis: Lead field surveys of existing conditions, identify non-compliant infrastructure, and investigate equipment failures to diagnose malfunctions and recommend mitigation strategies.

• BIM & Schematic Development: Develop and interpret complex blueprints, technical drawings, and schematics, ensuring all designs align with mechanical, plumbing, and fire codes.

• Technical Documentation: Write high-level performance requirements, construction specifications, and installation manuals for mission-critical projects.

Required Qualifications

• Education: B.S. in Mechanical Engineering from an ABET-accredited college.

• Citizenship: U.S. Citizenship is required.

• Security Clearance: Active US Security Clearance.

• Experience: Minimum of 3+ years of experience, preferably within a design firm setting.

• Licensure: EIT (Engineer in Training) status.

• Software Proficiency: Proficiency with 2D/3D CAD (AutoCAD and SolidWorks preferred) and Microsoft Office.

• Technical Skillset: Proven experience with shop/hand tools and the ability to perform engineering calculations with limited supervision.

Preferred Qualifications

• Licensure: Active Professional Engineer (PE) license.

• Advanced Analysis: Experience with Computational Fluid Dynamics (CFD) software.

• Modeling Tools: Proficiency with Trane Trace or Carrier HAP.

• Sector Knowledge: Deep understanding of commercial/industrial HVAC systems and specialized utility piping.
