RMB Consulting vs A2e Technologies: overview

RMB Consulting

RMB Consulting has operated in embedded systems design and consulting since 1995, run by founder and chief engineer Nigel Jones, who brings more than 30 years of professional embedded systems engineering experience and a long-running record of public technical writing on firmware design. For a client hiring a small team, working directly with a single named, 30-year-tenured engineer, rather than being assigned whichever staff member is available, is close to the smallest and most direct version of an engineering-hire relationship this list offers.

A2e Technologies

A2e Technologies was founded in 2004 and is headquartered in San Diego, California with a team reported between 11 and 50 engineers, commonly cited around 47. The firm's anti-tamper hardware security work under ITAR certification means its engineers carry a specific security clearance and process discipline most teams don't hold, a real factor for a hiring manager building a program that needs cleared personnel rather than just technically capable ones. Beyond that specialty, the team also does general hardware, FPGA, and firmware development for commercial clients.

RMB Consulting vs A2e Technologies: pros and cons

RMB Consulting
+ 30 years of professional embedded engineering experience concentrated in one named, publicly verifiable principal
+ A substantial public technical writing record lets a hiring buyer evaluate expertise before ever making contact
+ 30 years of operating history under the same founder gives continuity most larger firms can't offer
+ Team size of 1 to 10 means zero layers between the client and the engineer doing the work
- A team of 1 to 10 people severely limits capacity for a large or multi-workstream engagement
- No published pricing or minimum engagement figure
- Availability may be constrained given the founder-led, low-headcount structure
A2e Technologies
+ ITAR certification means the team already carries the clearance and process discipline a defense-program hiring manager would otherwise need to vet separately
+ Anti-tamper hardware security specialization is a specific, uncommon skill set within the team
+ 21 years of operating history in aerospace, defense, and space engineering
+ Combines hardware, FPGA, and firmware capability on the same team, useful when a role needs to span disciplines
- ITAR-focused positioning is a narrower fit for commercial-only hiring needs without export-control requirements
- 11 to 50 employees limits how many engineers can be dedicated to concurrent programs
- No published pricing or minimum engagement figure
