DornerWorks vs Timesys: 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.
Timesys
Timesys Corporation was founded in 1996 by principals associated with Carnegie Mellon University and built one of the first real-time-enhanced embedded Linux distributions. Headquartered in Pittsburgh, Pennsylvania with roughly 60 employees, Timesys built a long-running specialty in embedded Linux security, engineering services, and long-term maintenance tooling. In December 2023 the company was acquired by Lynx Software Technologies, and buyers evaluating Timesys today should confirm current organizational structure and service continuity directly, since acquisitions of this kind typically bring some integration transition period.
