Questions about Apex flight software and GNC jobs
How many flight software and GNC jobs is Apex hiring for?
12, counted on the Apex careers site at SpaceJobs.Now's latest read. The full Apex openings list sorts every role by discipline.
What is the salary range for flight software and GNC jobs at Apex?

What does Apex look for in these roles?
A computer science, aerospace or electrical engineering degree; C/C++ for flight code, control theory for GNC. The posting itself sets the bar (degree, years, clearance or citizenship), so read it first.
How fresh is this list, and where do I apply to Apex?
SpaceJobs.Now reads the Apex careers site every night; a role drops off once Apex takes it down. Open any role for the complete description, and the Apply step hands you to Apex's own form. No real space employer charges a fee to be hired, so treat any request for money as a scam.
