Project Management/Product Development/Technical Oversight


Role will require technical oversight for major and fairly complex projects (numerous interdependencies and implications) that involve a large team.  Responsibilities include concept development based on engineering and industrial design requirements, feasibility/risk assessment, detailed mechanical design and simulations, generation of technical documentation, engineering level verification activities and results analysis, design qualification plan development and execution, and product support throughout complete product life cycle.


Workflow planning: Plan multiple projects simultaneously.  Estimate, track & complete project on time and within budget.  Plan and coordinate detailed aspects of the engineering work associated with specific project task.  Develop technical project workflow plan, including key milestones, priorities and resource needs.  Reconcile inherent conflicts that exist in product design to achieve higher order business outcomes.


Risk mitigation and risk management: Identify technical program issues/risks and potential workaround and communicate details to the team.  Monitor key metrics for potential deviation in order to mitigate risk early and take appropriate action. Identify recommended changes where appropriate to ensure success criteria and deadlines are continuously met and provide information to the cross-functional team.


Analysis, Testing, and Qualification


Structural analysis of conceptual designs to determine viability.  Work with other disciplines and suppliers to ensure design is manufacturable and within BOM cost goals.


Hands-on involvement and oversight of product verification testing.  This includes troubleshooting and determining solutions


Team Leadership


Provide counsel and technical recommendations to cross functional team to ensure project progress and deliverables are met, raising issues that impede product viability.  Propose potential solutions to address issues and ensure all potential implications are considered.


Identify problems and actively devise appropriate solutions for both technical problems and those that may arise from differences in opinion.


Lead group of engineers and technicians.  Assure project milestones, scope, and timeline commitments are met.


Act as a mentor to less senior engineering team members, setting expectations, and providing input and feedback in a helpful way that fosters accountability.  Effectively train teammates per project needs.


Sustaining Engineering Support


Analyze and troubleshoot manufacturing and field issues, support 2nd sourcing efforts, and provide general engineering feedback for production staff.





  1. B.S in Mechanical Engineering. Advanced Degree highly preferred. 
  2. Professional Engineer License Holder preferred
  3. 6-10 years of experience designing, building, and testing electronic and/or loudspeaker products and related subsystems for commercial or professional markets. 
  4. Experience working with offshore developers preferred
