DornerWorks vs QuEST Global: overview
DornerWorks
DornerWorks is an embedded systems engineering firm founded in 2000 and headquartered in Grand Rapids, Michigan, serving aerospace, defense, medical, and industrial markets that require high-reliability software, electronics, and FPGA development. Over more than two decades the firm has grown into one of the larger embedded engineering design services firms in the US by team size, without disclosing exact current headcount. DornerWorks' focus on safety- and reliability-critical domains (aerospace, defense, medical) sets it apart from generalist embedded shops, and its FPGA and hypervisor (Xen-based) work is a recognized specialty in the embedded community.
QuEST Global
QuEST Global was founded in 1997 and is headquartered in Singapore, having grown into a large product engineering and lifecycle services company operating in more than 18 countries with over 90 delivery centers. The firm serves a very broad range of industries — aerospace and defense, automotive, energy, hi-tech, healthcare, rail, and semiconductors — with embedded engineering as one capability within end-to-end silicon and embedded engineering services offered to chipmakers and industrial clients. Reported employee counts vary substantially by source, from roughly 21,500 to over 32,000, reflecting the difficulty of pinning down an exact figure for a firm this size.
