Senior Mechanical / Physical Systems Integration Engineer

Senior Mechanical / Physical Systems Integration Engineer Location: Denver, CO Work Arrangement: Full-time, onsite 5 days per week Compensation: $155,000 to $210,000 base salary, plus equity and comprehensive benefits Travel: Approximately 10% to 15% Work Authorization: Applicants must be legally authorized to work in the United States without employer sponsorship now or in the future. The Opportunity Search Partner Group is recruiting a Senior Mechanical / Physical Systems Integration Engineer for an innovative technology company developing sophisticated automation systems that combine mechanical equipment, robotics, industrial controls, sensors, electrical systems, software, and building infrastructure. This is a hands‑on role for a mechanically grounded engineer who understands how complex physical systems are designed, manufactured, integrated, installed, commissioned, maintained, and improved in the field. You will own critical physical interfaces across equipment, structures, control boxes, sensors, wiring, power, I/O, and building infrastructure. You'll work closely with engineering and operations teams, equipment suppliers, architects, contractors, and consultants to ensure multiple subsystems function together as one reliable system. This is not primarily a software or theoretical systems‑engineering role. We are looking for someone with strong mechanical design and CAD experience who can take ownership from requirements and design through supplier execution, installation, validation, and field performance.

What You’ll Own

Mechanical & Physical Systems Integration

• Own the physical integration of complex mechanical and electromechanical equipment into buildings and operating environments.
• Define interfaces, installation requirements, tolerances, clearances, loads, operating conditions, and service requirements.
• Design and improve mechanical assemblies, sensor enclosures, control boxes, mounting solutions, and related hardware.
• Ensure designs meet requirements for manufacturability, installation, reliability, serviceability, maintenance, and cost.

Systems Engineering & Configuration

• Develop and maintain system architecture, Interface Control Documents (ICDs), requirements flow-down, tolerance/error budgets, drawings, and configuration-controlled documentation.
• Translate system, customer, site, and code requirements into clear and verifiable equipment requirements.
• Manage engineering drawings, revisions, BOMs, interfaces, and hardware configurations as designs evolve.

Supplier & Vendor Ownership

• Develop technical specifications for external equipment and technology suppliers.
• Review supplier designs and drawings, lead technical reviews, and establish acceptance and validation criteria.
• Manage engineering changes, supplier deviations, quality issues, and design evolution.
• Interface with suppliers of equipment such as vertical-conveyance systems, electrical control panels, AGV/AMR systems, sensors, and custom‑engineered equipment.

Installation, Validation & Field Performance

• Work with Operations, architects, general contractors, specialty subcontractors, and consultants to integrate equipment into the built environment.
• Support factory and site acceptance testing, installation, commissioning, and field troubleshooting.
• Lead root‑cause analysis across mechanical, electrical, controls, supplier, construction, and operational boundaries.
• Drive improvements based on field performance, reliability, maintenance, and serviceability.

Technical Leadership

• Lead design reviews and help cross-functional teams reach sound engineering decisions.
• Mentor less‑experienced engineers and strengthen engineering documentation, design discipline, validation, and problem‑solving practices.
• Provide senior‑level technical leadership and judgment without requiring formal management authority.

Required Qualifications

• Bachelor's degree in Mechanical Engineering or a related engineering discipline, or equivalent relevant experience.
• 8+ years of experience developing, integrating, manufacturing, or deploying complex mechanical or electromechanical systems.
• Strong hands‑on CAD and mechanical design experience, including components, assemblies, manufacturing drawings, and tolerance analysis.
• Experience taking physical products or equipment from design through manufacturing, installation, validation, and field deployment.
• Experience integrating mechanical structures with controls, sensors, wiring, power, I/O, and other electrical hardware.
• Experience with system requirements, interfaces, engineering drawings, configuration management, and engineering change control.
• Experience owning technical requirements and designs with external suppliers, including specifications, design reviews, acceptance criteria, and deviations.
• Strong troubleshooting and root‑cause‑analysis skills across multiple engineering disciplines.
• Practical understanding of manufacturability, installation, reliability, maintenance, and serviceability.
• Working knowledge of relevant safety, quality, and engineering standards.
• Strong technical writing, communication, and cross‑functional collaboration skills.
• Ability to travel approximately 10% to 15%.
• Ability and willingness to work onsite in Denver five days per week.
• Applicants must be legally authorized to work in the United States without employer sponsorship now or in the future.

Preferred Qualifications

• Experience in one or more of the following is particularly valuable: Industrial or manufacturing automation
• Material handling, warehouse automation, conveyors, lifts, or vertical‑transport systems
• Robotics, AGVs, AMRs, or autonomous equipment
• Automotive, aerospace, defense, heavy equipment, or other complex machinery
• Large steel structures, industrial machinery, or electro‑hydraulic equipment
• Equipment integrated into buildings, warehouses, manufacturing environments, or other large facilities
• Factory/site acceptance testing, commissioning, field support, or sustaining engineering
• Supplier engineering, NPI, ECOs, FAI, MRB, or configuration management
• Building codes, permitting, fire/life safety, or AHJ interaction
• Industrial controls and communications, including PLCs, Modbus, OPC UA, CAN, TCP/IP, motors/drives, and safety‑rated I/O
• Product or functional safety standards such as UL, IEC, ISO, or ISO 13849
• Python, Linux, C++, MATLAB, LabVIEW, ROS/ROS2, or similar engineering tools

Why This Role Stands Out

This is an opportunity to help define the architecture rather than simply inherit it. You'll work across mechanical design, physical systems integration, supplier engineering, construction interfaces, testing, commissioning, and field deployment, with direct visibility into how your engineering decisions perform in the real world. For a senior engineer who enjoys solving difficult problems between traditional engineering disciplines and wants to remain close to the hardware, this role offers significant technical breadth, ownership, and impact. Principal‑level candidates are also encouraged to apply, with level and scope determined based on experience.

Compensation & Benefits

Base salary is $155,000 to $210,000, depending on experience, technical depth, and overall qualifications. The total rewards package also includes:

• Equity participation
• Comprehensive medical, dental, and vision coverage
• 401(k) with company matching
• Generous paid time off and paid holidays
• Life and disability coverage
• Additional company benefits
