DE Design Works vs EES: overview
DE Design Works
DE Design Works was founded in 2002 and operates from Chesterfield, Missouri with a team in the 11 to 50 employee range. Firmware has been a core, continuous practice since the company's founding rather than a service added later, and the team's rugged industrial, medical, and military application experience means its engineers have handled the specific constraints those product categories impose, not just general firmware work. For a hiring manager staffing a ruggedized or regulated product, that's the kind of narrow, verifiable experience worth checking directly.
EES
Embedded Engineering Solutions (EES) was launched in 2012 and is based in Tempe, Arizona, with reported headcount varying across sources from roughly 3 to 50 employees, most consistently described as a small, senior-led firm. The company specializes in contract firmware, embedded systems, and hardware design engineering for the industrial sector, and its own positioning leans on being senior-led rather than layered with junior staff. For a hiring buyer specifically avoiding a large delivery organization, that's the stated value proposition, not an incidental trait.

|---|---|
| + | Explicit senior-led positioning means the small team size is a deliberate choice, not just a growth-stage limitation |
| + | 13 years of operating history as a contract engineering firm for the industrial sector |
| + | Combines firmware, embedded systems, and hardware design in one team, covering multiple disciplines without separate specialist hires |
| + | Small size means a client's engagement represents a meaningful share of the firm's total capacity |
| - | Reported employee counts vary widely across sources, from roughly 3 to 50, worth confirming current headcount directly |
| - | Small team size caps capacity for a large or multi-workstream program |
| - | No published pricing or minimum engagement figure |
