▷ ROLE:  MANAGER, MECHANICAL ENGINEERING

Discipline Leader Responsible for managing mechanical engineering team. Establishing best practices, due diligence and continual learning. Responsible for teams output, growth and careers. 

Product Improvements Worked closely with product team to capture and implement over 90% of EVT product requests, including major access improvements and latching redesign

Thermal Improvements Conceived and developed thermal design improvements saving 5C-10C in very geometrically restrictive areas

Production Release Led team from EVT to successful DVT release of over 70+ custom parts compromising 4 complex modular assemblies.  This included several prototyping rounds, tolerance analysis and production drawing creation.  Worked closely with world class contract manufacturing in Asia and Mexico

Managed multiple outside engineering resources, hired team members, reported progress to C-Suit

Lunar Energy produces a Smart Home Electrification system, consisting of a smart battery and inverter combination that optimizes a homes power production, storage and usage.

part of their offering includes the Lunar Switch, a smart load shedding device.

NOTE: The device has been announced but is not yet released.

Category Consumer Power Electronics

My role Engineering Proposal Lead, Account Manager, Project Manager, Team Lead, Principal Engineer

The challenge Extremely tight packaging of multiple PCBs, large components and large gauge wiring into single breaker slot. Need to separate AC and DC. Complex thermal challenges requiring analysis, thermal prototyping and thermal design. Designed to meet UL916 Certification

Learnings Thermal paths are critical, FEA is often directional in nature. Tightly packaged devices demand tight coordination with full stack team.

Team Size 3 MEs, 3 EEs, 2 FW, External ID team + Client team

Budget ~$1M

Schedule 6 months

Released Soon

Note: Device is not yet released.

▷ ROLE:  STRATEGIC ADVISOR, MECHANICAL ENGINEERING DIRECTOR

Leading Design Driving mechanical development to ensure best architecture, minimizing risk and optimizing performance.  In both high level and down to the most minute details.

Scaling Production  Leading the design thru overseas contract manufacturer for high volume production.  Hands on problem solving, assembly and part quality management, process implementation thru tricky non-english speaking CM.  Development and implementation of reliability testing.

StartUp Management Advising first time entrepreneurs on what to expect, schedule and costs involved, when to bring in expertise and how to manage risk on a gen1 product.

Led the mechanical and electrical team to develop an enhanced Lyft signaling device providing higher tracking accuracy, ability to signal in daylight, and unmatched color control.

Managed cross functional team of ME/EE/ID/FW/Product/Client.

Packaged sensitive antenna electronics, explored unique mounting schemes and developed ambient light testing prototypes, solving for critical daylight visibility. Developed architecture for logo branding and masking. Brought development thru EVT2 and handed off to internal client engineering team.

Uncovered thermal challenges and assisted with solutioning.

Budget ~1.5M

Schedule 2 years

Released 2008

As the product had such an aggressive cost goal, I began by estimating a design, targeting likely high cost parts/assemblies, and using these sketches to obtain budgetary tooling and part cost.

Category Consumer Electronics

What is it 2nd generation smart thermostat aimed at cost reduction

My role Engineering Proposal Lead, Account Manager, Technical Oversight Scope Full engineering, from concept to detailing to CM Handoff

The challenge Achieve a high end consumer device look and feel at a lower cost.

Learnings Challenging to achieve audio feedback for snapping. Glass has a great high end feel.
