Lemberg Solutions vs QuEST Global: overview
Lemberg Solutions
Lemberg Solutions is a 200+ person embedded and full-stack engineering firm founded in 2007 and headquartered in Lviv, Ukraine, with additional offices in Hamburg, Germany, London, United Kingdom, and Kraków, Poland. At 200+ people, it sits well above the smallest boutiques on this list but far below the multi-thousand-engineer generalist firms — a size where embedded is still unambiguously the firm's core business, not one line item competing for resourcing against unrelated business units, while still having enough bench depth (electrical engineering, firmware, embedded Linux, FPGA, connectivity, edge AI, cybersecurity) to staff a program with several parallel workstreams. ISO 9001/27001/13485 certification and named clients (Astronics, Caltech, Speede, Ferno, Cellink, Bosch Rexroth) back the claim with checkable references rather than scale alone.
QuEST Global
QuEST Global was founded in 1997 and is headquartered in Singapore, operating over 90 delivery centers across 18+ countries serving aerospace and defense, automotive, energy, hi-tech, healthcare, rail, and semiconductors. At 20,000+ people spanning seven-plus unrelated verticals, this is among the most diversified generalist engineering firms on this list — embedded and silicon engineering is one capability serving chipmakers directly, but structurally a small piece of a very large, broad organization.

Lemberg Solutions vs QuEST Global: pros and cons
| Lemberg Solutions | |
|---|---|
| + | Large enough (200+) to staff multiple parallel workstreams without embedded competing internally against unrelated business units for resourcing |
| + | ISO 9001, ISO 27001, and ISO 13485 certifications give a specific, checkable quality signal beyond team size alone |
| + | Named clients (Astronics, Caltech, Speede, Ferno, Cellink, Bosch Rexroth) support reference-checking before committing |
| + | Full IP and source code transfer to the client on delivery, standard across every engagement |
| + | Named public case studies with specific outcomes rather than generic capability claims |
| - | Does not manufacture at scale — teams wanting one specialist agency through mass production will still need a separate manufacturing partner |
| - | Does not carry regulatory certification itself — supports documentation but the client retains ownership of the certification process |
| - | No published rate card — cost comparison against smaller boutiques or larger generalists requires a direct quote |
| QuEST Global | |
|---|---|
| + | 90+ delivery centers across 18+ countries support very large, globally distributed engineering programs |
| + | End-to-end silicon and embedded engineering services offered directly to chipmakers, not just downstream product companies |
| + | Broad vertical coverage means one vendor can support embedded needs across multiple business units |
| - | Reported employee counts vary widely by source (21,500 to 32,000+), making exact capacity hard to verify |
| - | Embedded/silicon engineering is one capability among many verticals rather than the firm's central specialization |
| - | Scale and process overhead of a firm this size may be a mismatch for small, fast-moving embedded projects |
