Mechanical Trailer Engineer (Hybrid- Annapolis, MD)
About The Position
The C-UAS Mechanical Engineer – Trailer, will lead the mechanical retrofit of existing emergency response trailers into deployable C‑UAS platforms—re‑engineering chassis structures, mast systems, equipment racks, environmental controls, and on‑board power—and integrating them with RF/radar/EO‑IR sensors, C2 compute, and network/backhaul. Deliver complete design packages, calculations, and verification evidence mapped to DHS SELC artifacts and technical review exit criteria for acceptance and fielding. This role ensure the modified trailers remain road‑legal (lighting, reflectors, brakes, wiring; cargo securement), safe to operate and service (system‑safety, LOTO), and compliant with EPA Tier non-road engine requirements, NEC grounding/bonding for portable/trailer‑mounted generators, portable distribution, truck‑trailer electrical interconnects, and appropriate enclosure ratings for outdoor service.
Requirements
- Must be a U.S citizen with an ACTIVE security clearance of at least the SECRET level.
- Bachelor’s degree in Mechanical Engineering or allied discipline.
- 8+ years in mechanical engineering with hands‑on trailer/mobile platform retrofit experience.
- Demonstrated working knowledge of 49 CFR Part 393 and FMCSA cargo securement performance/WLL rules.
- Experience integrating gensets and portable distribution with NEC‑compliant grounding/bonding for portable/trailer‑mounted systems and UL 1640‑listed equipment.
- Familiarity with EPA Tier 4 non-road CI engine requirements for mobile generators.
- Ability to execute system‑safety and LOTO programs and translate them into shop/field procedures.
- Proficiency with CAD/PLM and design release; strong documentation discipline for SELC artifacts.
Responsibilities
- Develop the retrofit architecture, including structural reinforcements, mast/pedestal interfaces, sensor racks, and equipment bay layouts; produce weight/CG and stability analyses for towing and deployed states.
- Engineer cargo securement systems to meet performance criteria.
- Redesign or validate mast systems, wind/road load cases, hard stop/locking features, and lifting/rigging points with appropriate safety factors.
- Select/retrofit diesel generator sets and fuel systems; confirm Tier 4 applicability and labeling documentation for non-road CI engines used on mobile/trailer kits.
- Define compliant grounding/bonding for portable/trailer mounted generators and write the configuration/operating procedures used in the field.
- Specify portable power distribution equipment that is listed, including protective devices, GFCI, receptacles, and labeling suited to temporary installations.
- Update the truck–trailer electrical interconnect, where applicable, including cable routing/strain relief and corrosion resistant terminations suitable for service environments.
- Select enclosure ratings for controls, power electronics, and comms assemblies based on rain/washdown/corrosion exposure; document rationale in the design record.
- Run the system safety process in accordance with MIL STD 882E across retrofit, test, and fielding.
- Establish LOTO procedures and service placards for generators, lifts/masts, and rotating equipment.
- Produce CAD models/drawings, weldment and assembly details, load & CG calcs, generator sizing and wiring single lines, acceptance checklists, and as built packages that satisfy SELC artifact expectations and review exit criteria.
- Lead factory/site acceptance for retrofits: road tests, power up, grounding verification, LOTO drills, and environmental checks; record objective evidence for program acceptance and sustainment.
