Sr. Mechanical & Acoustic Engineer

POSITION PURPOSE

The Senior Mechanical & Acoustic Engineer is part of the Subject Matter Expert (SME) Engineering team and supports BAC’s New Product Engineering (NPE) organization by applying mechanical engineering expertise in sound, vibration, airflow, fan systems, pump systems, and overall system performance to develop and optimize new products. This role provides technical leadership for analyses, selections, tests, and design guidance that improve product acoustic performance, vibration robustness, energy efficiency, manufacturability, and reliability.

• Lead sound, vibration, fan, pump, and mechanical-system performance work for NPE programs, ensuring technical deliverables are completed on time, on spec, and aligned with product objectives.
• Perform fan selections, pump selections, airflow assessments, acoustic evaluations, and mechanical-system tradeoff studies to optimize product performance, sound, cost, manufacturability, and reliability.
• Support product architecture and design decisions by evaluating how fan type, fan speed, motor selection, inlet/outlet geometry, attenuation, airflow paths, structural features, pump configuration, and other mechanical design choices affect sound, vibration, and overall performance.
• Plan and execute technical portions of multi-stage NPE assignments, including analysis, test planning, data review, design recommendations, documentation, and follow-up actions.
• Analyze sound, vibration, airflow, and mechanical performance data; identify root causes, trends, and improvement opportunities; and translate findings into actionable recommendations for product design teams.
• Collaborate with the R&D Lab and test engineers to define test requirements, instrumentation needs, data collection methods, and acceptance criteria for sound, vibration, fan, pump, and system-level performance testing.
• Support development and validation of analytical methods, selection tools, calculation templates, and design guidelines used by NPE teams for fan, pump, sound, vibration, and mechanical-system decisions.
• Investigate and resolve sound, vibration, fan-system, pump-system, and mechanical performance issues identified during NPE testing, product qualification, field evaluations, or regional engineering support.
• Prepare clear technical reports, presentations, calculations, and recommendations for engineering audiences; communicate technical tradeoffs effectively across design, lab, manufacturing, regional, and leadership stakeholders.
• Provide technical support and guidance to junior engineers and designers, including review of analyses, interpretation of test data, and coaching on sound, vibration, fan, pump, and mechanical-system engineering fundamentals.
• Contribute to continuous improvement of BAC’s sound, vibration, and mechanical performance engineering practices by documenting lessons learned, improving analysis/test methods, and staying current with relevant technologies, standards, and industry practices.
• Remain current with relevant industry practices, analytical techniques, and technologies related to fans, pumps, acoustic engineering, vibration, rotating equipment, and mechanical-system performance.

The Senior Mechanical & Acoustics Engineer reports to a Team Lead or higher-level Mechanical/Acoustic Engineer, and supports multiple NPE programs and regional engineering needs. This role provides technical and project support to other departments. The engineer is expected to work independently on multi-stage assignments, plan and schedule technical work, and seek assistance only when unusual or complex issues require additional expertise.

The role is part of a team that functions as a Center of Excellence (COE) in the Mechanical/Acoustic field, providing Subject Matter Expertise to other engineers in the business. The role requires frequent cross-functional interaction with NPE, Thermal Engineering, Structural Engineering, Controls Engineering, Global Components, R&D Lab, Manufacturing, Supply Chain, vendors, and regional engineering teams. The work directly influences new product performance, sound ratings, product robustness, customer…
