Sr. Principal Systems Engineer

The job title says 'Principal Systems Engineer' but the posting is located in Melbourne, FL (onsite), while the body text references Cedar Rapids, IA as the development location — the official posting address is Melbourne, FL (313 1344 S Babcock St), so Melbourne/Palm Bay CBSA is used.

The role is a Systems Engineering position focused on safety-critical avionics computing systems (DAL A, ARP4754B). No single SOC code maps cleanly: 15-1299 (Computer Occupations, All Other) is used as the best fit for embedded/avionics systems engineering; 15-1211 (Computer Systems Analysts) is the closest runner-up.

The safety-critical standards requirement (DO-178C, DO-254, ARP4754A/B) is listed as a single gate with alternatives — any one of these satisfies the requirement.

'Requirements authoring and validation' is listed as a hard gate in the required qualifications but names no specific tool or platform, so it is omitted from the skills list per schema rules. The standards (DO-178C etc.) are the concrete named technologies captured.

The degree requirement states 'STEM degree + 10 years OR Advanced Degree + 7 years' — because equivalent experience pathways exist and no single degree level is an absolute gate, the degree requirement is set to None.

The posting title says 'Principal' but the requirements (10 years, component/product-level scope within a business unit) are consistent with a Senior-level role. 'Principal' at large aerospace primes like RTX/Collins often maps to what the broader market calls Senior.

Security clearance is explicitly stated as 'None/Not Required.'

Ignored 1 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): embedded hardware/software testing.
