Senior Mechanical Engineer

We are seeking a Senior Mechanical Engineer to lead the mechanical design and implementation of modular infrastructure solutions-such as containerized enclosures, skids, and factory-built assemblies-serving the Data Center, Utility, Fiber, and Telecommunications sectors. Operating within a multi-discipline civil/electrical/mechanical team, this role provides technical leadership across HVAC systems, piping/fluid systems, metal forming/fabrication, dynamic analysis, material selection, and control systems integration. The ideal candidate combines deep technical proficiency with practical manufacturing experience, driving projects from concept through detailed design, factory acceptance testing, commissioning, and handover.

Leadership & Functional Competencies

Leadership Competencies

• Technical Leadership & Mentorship: Guides junior and mid-level engineers; sets design direction, reviews calculations/drawings, and elevates team capability.
• Project Ownership: Leads workstreams or small programs; scopes, estimates, schedules, manages risk, and drives on-time, on-budget delivery.
• Cross-Functional Influence: Aligns stakeholders across Electrical, Civil/Structural, Manufacturing, Quality, Supply Chain, and Field Services; communicates tradeoffs and decisions clearly.
• Decision Quality: Makes data-driven decisions balancing performance, cost, schedule, and safety; escalates risks early with mitigation plans.
• Continuous Improvement: Champions DFM/DFA, standardization, templates, and lessons learned; drives first-time-right outcomes and reduction of rework.

Functional Competencies

• HVAC Engineering: Advanced heat load and psychrometric analysis; air/coil/filtration selection; airflow management/containment strategies; redundancy (N+1/N+N); sequences of operation for PLC/BAS.
• Piping & Fluid Systems: P&IDs, isometrics, line sizing, pump selection (system curves/NPSH), valve/strainer specs, pressure drop and transients; supports for transport and seismic considerations.
• Metal Forming & Fabrication: Sheet metal, weldments, and structural framing for modular enclosures/skids; tolerancing (GD&T), finishes, corrosion mitigation, and inspection criteria.
• Dynamic/Structural Analysis: Vibration, fatigue, shock/transport loads; interpretation and validation of FEA/CFD results; modal and stability considerations for rotating equipment and structures.
• Materials Engineering: Selection for strength, thermal behavior, corrosion/UV resistance, and manufacturability; knowledge of steels, aluminums, stainless alloys, coatings, and composites.
• Controls Integration: Defines control narratives, I/O, and sequences for mechanical subsystems; collaborates with PLC/BAS teams on sensors, actuators, VFDs, dampers, and alarming.
• CAD & Product Definition: Directs creation of 3D models and 2D drawings, BOMs, specs; enforces drafting standards, GD&T, and configuration management in PLM/PDM.
• Validation & Commissioning: Plans and executes FAT/SAT, airflow/thermal validation, pressure/leakage tests, and performance verification; leads structured RCA and CAPA.

Key Responsibilities

Design & Development

• Lead mechanical design for modular products (enclosures, skids, racks), including HVAC architecture, airflow/thermal design, ducting, coil selection, and control sequences.
• Engineer piping and fluid systems: develop P&IDs/isometrics, perform line sizing and pump calculations, specify valves/accessories, and define supports/insulation.
• Architect sheet metal and structural assemblies for manufacturability and durability; specify weld symbols, finishes, hardware, and inspection methods.
• Perform or direct dynamic/mechanical analyses (vibration, fatigue, handling/transport loads); review and approve FEA/CFD studies and test correlation.

Documentation & Configuration Control

• Produce and approve calculation packages, design memos, models, drawings, specifications, and test plans.
• Drive ECO/MOC processes, redlines, as-built updates, and accurate metadata within PLM/PDM and document control systems.
• Create and maintain standard detail libraries, design checklists, and templates to improve repeatability and quality.

Project Execution & Collaboration

• Plan and manage engineering work across multiple concurrent projects; provide reliable estimates and status; identify and mitigate risks.
• Lead design reviews, HAZID/HAZOP, and manufacturability/constructability assessments; incorporate feedback into designs.
• Collaborate with vendors/OEMs: develop RFQs, conduct technical bid evaluations, review submittals/data sheets, and support make-vs-buy decisions with Supply Chain.

Manufacturing, Test & Field Support

• Support fabrication and assembly on the factory floor; resolve build issues through clear dispositions (ECR/NCR) and rapid problem solving.
• Develop and execute FAT/SAT and commissioning procedures; support start-up and performance validation at customer sites as needed.
• Lead root-cause investigations and implement corrective/preventive actions (CAPA) to address quality, reliability, or performance gaps.

Compliance, Safety & Reliability

• Apply relevant codes, standards, and best practices (e.g., ASHRAE, AMCA, ASME, ASTM, AWS, AISC/ACI where applicable; customer and AHJ requirements).
• Ensure safety and reliability are designed in: guarding, lifting points, pressure boundaries, accessibility, service clearances, and life-cycle considerations.
• Contribute to reliability engineering (FMEA/RCM), spares strategy, and serviceability improvements.

Physical Requirements:

Education:

• Bachelor's degree in Mechanical Engineering (or closely related discipline) required.
• Master's degree preferred (thermal sciences, mechanics, or related focus a plus).

Experience:

• 6-10 years of mechanical design experience in manufacturing or industrial product development; modular/data center/utility experience strongly preferred.
• Professional Engineer (P.E.) license preferred or ability to obtain within a reasonable time frame.
• Proven capability in HVAC, piping/fluid systems, sheet metal/weldments, dynamic analysis, material selection, and controls integration.
• Proficiency with 3D/2D CAD (e.g., Autodesk Inventor, SolidWorks, AutoCAD Mechanical) and PLM/PDM systems; expert application of GD&T and drafting standards.
• Hands-on experience with validation testing (FAT/SAT), commissioning, and field support; familiarity with FEA/CFD workflows and test correlation.
• Working knowledge of applicable codes/standards (ASHRAE, AMCA, ASME, ASTM, AWS; and customer or AHJ specifications).

Skills & Abilities:

• Clear, concise communicator-able to convey complex technical content to stakeholders at all levels.
• Strong analytical and problem-solving skills; decisive and accountable with sound engineering judgment.
• Highly organized, responsive, and effective at prioritizing in a fast-paced, multi-project environment.
• Collaborative leadership style with the ability to mentor peers and junior engineers and to influence cross-functional outcomes.
