We are seeking a Mechanical Engineer to join our team and drive the end-to-end development of innovative ConnectDER products. In this role, you will apply sound engineering principles and system-level awareness to break down complex requirements, develop robust technical solutions, and collaborate cross-functionally across the organization to bring products from initial concept to manufacturing hand-off. 

Duties include:

• End-to-End Product Design & Ownership:
• Drive medium-sized mechanical designs autonomously from initial concept through manufacturing hand-off and product sustaining.
• Distill complex product requirements into detailed technical specifications, interface requirements, and design concepts.
• Create 3D CAD models, tolerance analyses, detailed part/assembly drawings, and Bills of Material (BOMs), balancing trade-offs between performance, manufacturability, technical debt, and speed.
• Break down complex engineering scope into manageable tasks, track progress against estimates, and anticipate roadblocks to keep development timelines on schedule.

• Testing, Verification, and Risk Mitigation:
• Own early-stage product testing by developing test procedures, evaluating system capabilities, and anticipating potential design edge cases.
• Collect, analyze, and summarize data into clear test reports. Use findings to refine designs and mitigate technical risks early in the development cycle.
• Debug design and manufacturing issues proactively.
• Prototyping & Fabrication:
• Fabricate, 3D print, and modify components to build prototype units.
• Build prototype and sample units for use in product evaluation, certification, utility and customer approval, and marketing/tradeshow models.
• Cross Functional Engagement
• Present technical decisions, trade-offs, and risks clearly during design reviews and cross-functional planning sessions.
• Collaborate with cross-functional partners (PMO, QA, Manufacturing, and Supply Chain) to align on implementation details, supplier selection, and resourcing.
• Serve as a technical role model and provide guidance to junior team members to help elevate the engineering team’s overall capabilities.
