What does a Part Time Mass Properties Engineer do?

A Part Time Mass Properties Engineer is responsible for analyzing and managing the weight, balance, and mass distribution of vehicles or aircraft to ensure they meet safety, performance, and regulatory requirements. They typically work with design teams to track changes in mass properties throughout the development process and provide recommendations to optimize weight and balance. Their part-time role means they may focus on specific projects or phases, contributing their expertise as needed. This job is crucial in industries like aerospace, automotive, and defense, where accurate mass properties are essential for safety and efficiency.

What are some common challenges faced by part-time Mass Properties Engineers, and how can they be managed?

Part-time Mass Properties Engineers often encounter challenges in staying updated with project changes and ensuring seamless communication with full-time team members. Since mass properties work is highly collaborative, balancing a reduced schedule with the need for timely data analysis and reporting can require strong organizational skills. Proactively coordinating with project leads, leveraging digital collaboration tools, and maintaining clear documentation can help part-time engineers stay aligned with project goals and deliverables.

What are the key skills and qualifications needed to thrive as a Part Time Mass Properties Engineer, and why are they important?

To thrive as a Part Time Mass Properties Engineer, you need a strong background in physics, engineering (typically aerospace or mechanical), and proficiency in mass properties analysis, often supported by a relevant degree. Familiarity with tools such as CATIA, SolidWorks, and mass properties analysis software, as well as experience with industry standards, is essential. Strong attention to detail, analytical thinking, and effective communication are vital soft skills for collaborating with multidisciplinary teams and conveying complex findings. These skills and qualities ensure accurate mass distribution assessments, which are critical for the safety, performance, and compliance of aerospace products.

What is the difference between Part Time Mass Properties Engineer vs Part Time Mechanical Engineer?

AspectPart Time Mass Properties EngineerPart Time Mechanical Engineer
Required CredentialsBachelor's in Mechanical or Aerospace Engineering, knowledge of CAD and mass properties analysisBachelor's in Mechanical Engineering, CAD proficiency, engineering fundamentals
Work EnvironmentDesign labs, aerospace or automotive industries, project-basedManufacturing plants, design offices, product development
Industry UsagePrimarily in aerospace, automotive, defense sectorsBroadly in manufacturing, product design, industrial sectors

Part Time Mass Properties Engineers focus on analyzing and calculating the mass distribution of products, often in aerospace or automotive industries, requiring specialized knowledge of mass properties and CAD tools. Part Time Mechanical Engineers have a broader role in designing, testing, and improving mechanical systems across various industries. While both roles require engineering fundamentals, the Mass Properties Engineer specializes in weight and balance analysis, whereas the Mechanical Engineer covers a wider range of mechanical design tasks.

Job description

Job Summary:
T3i builds mission-critical unmanned systems designed to improve US forces operational and lethal capabilities on the battlefield. Our Blackfoot platform is a tactical FPV drone system engineered for reliability, adaptability, and rapid deployment. We operate in tight feedback loops between design, build, and field use, where hardware decisions directly impact mission outcomes.
We are a small, fast-moving team that values ownership, technical depth, and execution. We're looking for a Mechanical Engineer (ME) to support the mechanical architecture of our drone systems, from concept through production.
The ME will design, fabricate, test, and iterate on complete mechanical systems including airframes, propulsion integration, payload bays, and structural hardware. The ME will work hands-on in the shop, in integration, and during flight testing, closing the loop between design intent and real-world performance.
Position Summary:
The ME will be responsible for the design, integration, testing, and continuous improvement of the mechanical systems supporting the Blackfoot platform. This role emphasizes hands-on development, rapid iteration, and system-level ownership across the full hardware lifecycle. The ideal candidate thrives in fast-paced environments, is comfortable working across mechanical and electrical boundaries, and contributes to building reliable, field-ready systems.
Primary Responsibilities:
  • Support mechanical design across airframe, motor mounts, payload bays, amp; landing systems
  • Design and fabricate multi-component assemblies for high-performance drone platforms
  • Perform structural and FEA analysis to validate designs under flight, loads, and crash
  • Select and specify materials including CFRP composites, aluminum alloys, and engineering plastics for weight-critical applications
  • Integrate propulsion system components including motor mounts, ESC thermal management, and propeller clearance envelopes
  • Conduct mass properties analysis (CG, MOI) and coordinate with flight systems team to maintain acceptable flight dynamics
  • Design vibration isolation solutions to protect sensitive electronics (IMU, cameras, RF systems) on propeller-driven airframes
  • Develop and maintain technical drawings with GD amp;T callouts per ASME Y14.5 standards
  • Build, test, and iterate hardware rapidly using real-world feedback from flight operations
  • Support MIL-STD-810 environmental testing (shock, vibration, temperature, humidity) and implement design improvements
  • Coordinate mechanical/electrical interface design including wiring harness routing, connector placement, and PCB mounting provisions
  • Drive designs from prototype through production (DFM/DFA, BOM, amp; build documentation)
Minimum Qualifications:
  • 3 years of hands-on mechanical engineering experience
  • Proven experience designing and fabricating real hardware systems
  • Strong CAD proficiency (SolidWorks preferred; CATIA, Fusion 360, or NX accepted)
  • Demonstrated FEA experience (SolidWorks Simulation, ANSYS, or Abaqus)
  • Working knowledge of GD amp;T per ASME Y14.5
  • Experience with lightweight structural materials including CFRP composites or aluminum alloys
  • Familiarity with DFM/DFA and hands-on prototype fabrication (CNC machining, FDM, SLA)
  • Understanding of rotating propulsion system mechanics, vibration, and dynamic loading
  • Ability to work independently and take ownership of ambiguous design problems

Preferred Qualifications:
  • Hands-on experience building, repairing, or flying FPV or tactical UAS platforms
  • Familiarity with MIL-STD-810 test methods and environmental qualification requirements
  • Experience with mass properties management and CG/MOI analysis for UAS platforms
  • Knowledge of battery mechanical integration and thermal management in UAS airframes
  • Experience coordinating with external machine shops or composite fabricators
  • SolidWorks CSWA or CSWP certification
  • Familiarity with payload integration for ISR or EW systems on tactical UxS
  • Experience working in fast-paced R amp;D or defense environments

Clearance Requirements: Secret security clearance or be able to obtain one within 90 days of hire
Required Background Check: HireRight background check amp; drug screening
Type of Employment: Part-Time (with potential to transition to full time)
