USA Firmware vs Oxalis Design: overview
USA Firmware
USA Firmware was founded in 2011 by Bob Scaccia and operates from Brecksville, Ohio with a team of around 17 people. Leadership brings a stated 150-plus combined years of experience concentrated in a small team, which for a hiring buyer means the average tenure and seniority per engineer is unusually high for a firm this size. The managed design process bundles electrical engineering, firmware, FPGA design, and Linux work, so a client hiring this team gets multi-discipline coverage without assembling separate specialists.
Oxalis Design
Oxalis Design is a Bristol, UK electronics and embedded systems consultancy founded by Alex Turner and Alex Thornicroft, both experienced electronics and software engineers who remain personally involved in client work rather than having moved fully into management. For a client evaluating team fit at the smallest scale, this means the people making architecture decisions are the same people who will be reachable throughout the engagement, not a sales contact who hands the work to unnamed staff.
