Lemberg Solutions vs EES: overview

Lemberg Solutions

Lemberg Solutions was founded in 2007 in Lviv, Ukraine and has grown to a 200+ person team with additional offices in Hamburg, London, and Kraków. For a buyer evaluating who they'd actually work with, the firm's scale means dedicated engineers rather than shared generalist staff, backed by direct partnership status with NXP, STMicroelectronics, and Microchip and an in-house hardware lab the team uses daily for board bring-up. ISO 9001, ISO 27001, and ISO 13485 certifications reflect process discipline a hiring manager can expect from the assigned team, not just a company-wide policy on paper.

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.

Lemberg Solutions vs EES: pros and cons

Lemberg Solutions
+ 200+ engineers give a hiring team dedicated staff rather than shared generalists spread thin across many clients
+ In-house hardware lab means the assigned team validates board bring-up itself rather than waiting on a separate department
+ Direct NXP, STMicroelectronics, and Microchip partner status is a credential the actual engineers on a project can draw on directly
+ ISO 9001, ISO 27001, and ISO 13485 certifications reflect process discipline built into daily team workflow, not just policy documents
+ Full IP and source code rights transfer to the client on delivery
- Does not run mass production in-house, so a manufacturing handoff still needs a separate team
- Does not handle regulatory certification filings on the client's behalf
- No published minimum engagement figure, so team-size and cost fit needs a direct scoping conversation
EES
+ 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
