Brett Walker
Electro-Mechanical Control Systems Engineer, Allison Transmission
I design, test, and certify the electronics inside electrified commercial powertrains, then translate what the lab finds into decisions the business can act on.

Hardware, compliance, and the business case between them
Seven years across passenger automotive, defense, and commercial hybrid markets, currently on Allison’s eGen Force and eGen Flex electrified powertrain programs.
EMC and regulatory compliance
I built and commissioned Allison’s $100K in-house EMC pre-compliance lab, so control modules and shift selectors get debugged against conducted and radiated limits before they ever go to an outside lab.
I write the compliance matrices, test plans, and statements of work, and I’ve led military product certification strategy across the US, India, Sweden, and Italy, plus Conformity of Production submittals for the EU.
Power electronics and hardware
Converters, inverters, and the protection around them: input EMI filters, smart high-side switching, edge-rate control, and PCB layout in Altium and OrCAD.
Designs get a worst-case circuit analysis in MathCAD across temperature, tolerance, and supply transients, and a DFMEA and PFMEA before they leave concept.
Programs and strategy
I’ve carried electronic products through concept, design, and production validation, and I turn technical and regulatory findings into executive briefings, including the case for Allison’s Next Gen Transmission Controller.
Earlier, in procurement at North American Lighting, strategic sourcing delivered $1.2M in cost avoidance.
Featured work
Two engineering builds and one market analysis, all asking the same question: how does a piece of technology earn its place in a vehicle or a portfolio?
From requirement to compliant hardwareNew
Input-filter stability, worst-case analysis, transient protection, and how I find and fix emissions in a switching supply, with working calculators.

Conexus Rising 30, Class of 2026
Named to Conexus Indiana’s Class of 2026, honoring Indiana’s most impactful young professionals in advanced manufacturing and logistics. Allison Transmission nominated me for building its $100,000 in-house electromagnetic testing lab, work Allison credits with eliminating multiple electronic product design iterations.
Let’s talk power electronics, EMC, electrification, or venture-side technology roles.
