Why we read it this way (12)
The role carries significant team-leadership responsibilities (leading 5–15 engineers, serving as primary technical interface with government customers, mentoring junior/mid engineers), which creates genuine ambiguity between a senior individual-contributor SOC (15-1252) and a people-management SOC (11-3021). However, the posting emphasizes hands-on technical work — architecture definition, code reviews, flight test support — so 15-1252 was chosen as primary.
The basic qualifications state '12+ years of relevant technical experience, or 10+ years with a master's degree.' The lower bound of 10 years (with a master's) was not used as the overall years minimum; the stated floor without a master's is 12 years.
C and C++ are listed together in the posting ('C/C++') as a single expert-level requirement; C++ is used as the primary skill name with C as an alternative.
VxWorks and FreeRTOS are listed as examples of RTOS environments; RTOS is captured as the required capability, with VxWorks and FreeRTOS as preferred specifics.
FACE, OMS, and SOSA are listed together as open architecture framework examples under Preferred Qualifications.
Docker and Kubernetes appear together under Preferred Qualifications as containerization examples.
MATLAB and Simulink appear together under Preferred Qualifications.
DO-178C and MIL-STD-882e appear together under Preferred Qualifications as software development standards examples.
The degree requirement specifies a minimum GPA of 3.0 or higher, which cannot be represented in a structured field — hiring managers should be aware of this additional gate.
'Open systems architecture' and 'MOSA' are listed as distinct required concepts in the Basic Qualifications and are retained as separate skills despite conceptual overlap.
Ignored 1 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): open systems architecture.
Requires a Secret clearance — the cleared population is a small fraction of this occupation, so the real candidate pool is materially smaller than the estimate below, which does not model clearance.
