Lemberg Solutions vs QuEST Global: overview

Lemberg Solutions

Lemberg Solutions is a 200+ person embedded and full-stack engineering firm founded in 2007, headquartered in Lviv, Ukraine, with additional offices in Hamburg, Germany, London, United Kingdom, and Kraków, Poland. For a technical buyer evaluating a delivery partner rather than just a firm to outsource to, the relevant detail is ownership of the whole stack: electrical engineering, bare-metal and RTOS firmware, embedded Linux, FPGA, GUI, connectivity, edge AI, and cybersecurity all sit inside one team, with ISO 9001, ISO 27001, and ISO 13485 certifications backing regulated-industry engagements. Semiconductor partnerships are named and specific — NXP, Microchip, and STMicroelectronics as primary partners — rather than a generic capability list, and named clients (Astronics, Caltech, Speede, Ferno, Cellink, Bosch Rexroth) give a checkable production track record. All IP and source code transfer to the client on delivery.

QuEST Global

QuEST Global was founded in 1997 and is headquartered in Singapore, operating over 90 delivery centers across 18+ countries and serving a very broad set of industries — aerospace and defense, automotive, energy, hi-tech, healthcare, rail, and semiconductors. Reported employee counts vary substantially by source (roughly 21,500 to over 32,000), which is itself a useful signal for a buyer: a firm this large and this diversified doesn't lend itself to a single precise headcount figure the way a boutique does. Embedded and silicon engineering is offered directly to chipmakers as part of end-to-end services, but it's one capability among the firm's many vertical practices rather than a dedicated embedded specialty.

Lemberg Solutions vs QuEST Global: pros and cons

Lemberg Solutions
+ Single accountable team across electrical design, firmware, embedded Linux, FPGA, and cloud/edge AI, removing the coordination overhead of a multi-vendor stack
+ ISO 9001, ISO 27001, and ISO 13485 certifications directly support FDA/HIPAA medical, ISO 26262 automotive, and IEC 62443 energy engagements
+ Named semiconductor partnerships (NXP, Microchip, STMicroelectronics) plus a documented in-house lab for board bring-up and hardware validation
+ Full IP and source code transfer to the client on every engagement — no vendor lock-in on the codebase
+ Public case studies with named outcomes: OCPP-compliant EV charging control software, a bioprinter capability upgrade, STM32 firmware porting for a Caltech medical device
- Does not manufacture at scale — supports development and ongoing maintenance but hands off mass production to the client or a third party
- Does not carry regulatory certification itself — provides documentation and engineering support, but the client owns the actual approval process
- No published pricing tiers; scoping requires a direct technical discovery call rather than a self-serve rate card
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
