The Senior Mechanical Engineer will lead mechanical design projects, focusing on HVAC systems, plumbing, and industrial utilities while collaborating across engineering disciplines and adhering to safety standards.

Design, analyze, and develop mechanical systems and components using CAD and analysis (FEA/CFD). Support prototyping, testing, DFM, and cross-functional collaboration for product development across industries.

Design and engineer mechanical cooling systems for modular data center units, performing hydraulic and heat-transfer calculations, sizing equipment, developing vendor packages (CDUs, pumps, dry coolers), supporting prototypes and initial builds, and validating designs against test/commissioning data.

Design and develop the mechanical aspects of data-center robotics including end effectors, docking, and robot-plant interfaces. Rapidly prototype, test to failure, instrument trials, and productionize hardware with DFM, reliability, and spare strategies while collaborating closely with controls and software teams.

Engineer mechanical demand flexibility for data center cooling: model thermal inertia and headroom per site, design setpoint/staging/storage strategies, validate models via instrumented field tests, quantify operating risk in degrees/minutes/margins, and collaborate with controls engineers.

Design and develop aerospace-qualified pneumatic valves and control systems. Create CAD models, drawings, BOMs, and test procedures; build prototypes; perform testing, analysis, and GD&T; resolve manufacturing issues and support qualification and production documentation.

Perform independent audits of payment vouchers, change orders, and cost estimates for mechanical, plumbing, and HVAC construction projects; conduct desk and field audits for contract and code compliance; review contract documents and engineers' estimates; prepare audit reports and recommendations; provide technical support to resolve payment discrepancies.

Provide mechanical engineering domain expertise to create and review technical content used to train AI systems: review documents, develop and assess questions/solutions, give written and oral feedback, collaborate cross-functionally, resolve complex engineering problems, and improve data quality while working independently.

Perform nationwide on-site MEP property condition assessments (HVAC, plumbing, electrical, fire protection, vertical transportation), document deficiencies per ASTM standards, prepare PCA reports, estimate remediation costs, lead single-assessor or team engagements, mentor junior staff, and travel up to 50%.

The Mechanical Engineer will design project requirements, manage engineering schedules, interface with clients, and support installation efforts while ensuring compliance with specifications. They will lead engineering teams, manage project scope, and communicate effectively across departments.

Lead mechanical design and multidisciplinary project teams as technical authority and potential Engineer of Record. Oversee project planning, forecasting, quality management, and profitability. Drive business development, client presentations, firm leadership, staff mentorship, and technical standards to elevate company operations and secure work.

Lead mechanical engineering projects from concept through construction, overseeing deliverables (calculations, drawings, specs), team assembly and mentorship, equipment selection, interdisciplinary coordination, site visits, client meetings, and adherence to quality and industry standards (HVAC, plumbing, fire protection, energy modeling).

Lead and conduct mechanical and materials testing in the laboratory and field, including tensile, Charpy, leak/pressure and durability tests; install sensors and data-acquisition systems; analyze data and prepare technical reports; perform site inspections; manage projects and pursue business opportunities.

Design and model mechanical systems for data centers, manage project phases, lead BIM coordination, and ensure compliance with standards. Requires PE license and frequent travel.

Senior mechanical design engineer responsible for designing and documenting semiconductor test hardware (contactors, sockets, alignment frames), performing FEA/thermal/motion analyses, supporting NPI and prototype builds, managing PDM/EC0/BOM processes, collaborating with manufacturing and suppliers, and providing technical leadership to ensure performance, reliability, and manufacturability in high-volume test environments.

Design and deliver HVAC and mechanical systems for new and existing K-12 school projects. Prepare calculations, reports, drawings, specifications, and coordinate with architects, consultants, contractors, and agencies. Lead and supervise project teams, perform design review, ensure code and energy compliance, and manage multiple projects through construction. May sign and seal drawings and develop standards.

Lead mechanical engineering for aerospace hydraulic valves and actuation systems: drive design, trade studies, analysis, testing, standards compliance, and cross-project technical oversight. Provide customer-facing technical leadership, support safety analyses (SHA, FMEA, FTA), use FEA/DFSS methods, and mentor/coordinate multi-engineer efforts to deliver flight control products.

Provide technical engineering support for gas and steam turbines, generators, and balance-of-plant equipment. Duties include troubleshooting, root cause analysis, maintenance strategy development, outage planning and oversight, vendor coordination, economic justification for projects, and fleetwide rotating equipment support while collaborating with operations, maintenance, reliability, procurement, and external vendors.

The role involves designing electromechanical solutions for telecom systems, focusing on mechanical designs, thermal management, and product development. Responsibilities include overseeing prototype builds, collaborating with teams, and applying best practices in engineering.

Design, develop, test, and analyze thermal protection systems, textiles, and mechanical/electromechanical hardware for launch and flight vehicles. Create CAD models, manufacturing drawings, test fixtures, and requirement/verification documentation. Perform stress/thermal/fluid analysis, tolerance/GD&T assessments, risk mitigation, and present designs to stakeholders while supporting cross-functional teams for NASA, military, and commercial aerospace programs.

Deploys and commissions data center cooling and mechanical systems through equipment startup, functional and performance testing, and live handover. Supports operational reliability, diagnoses thermal and equipment issues (chilled water, CDU, direct liquid cooling), resolves field installation conflicts, monitors thermal performance under AI load, and authors commissioning checklists and maintenance run books.

The Mechanical Engineer will lead HVAC and district energy system designs, mentor junior engineers, and communicate with clients on feasibility and project documentation.
