What do Security engineers in Sunnyvale work on?

The roles on this page span a wide range of security disciplines. At the embedded end, engineers work on secure boot processes, hardware security module integration, and cryptographic foundations for vehicle and AI hardware platforms, as seen in the Cybersecurity Software Engineer โ€“ New Grad posting.

Security Engineer roles that state a salary

The employers' own advertised ranges, for individual roles at different levels โ€” not an average and not a market rate.

Sunnyvale office, hybrid or remote?

Almost all postings in this set specify on-site work in Sunnyvale; a small number are listed as hybrid. None are listed as remote. The network security role at Cerebras explicitly notes regular on-site data-centre work. For postings where the precise working arrangement is not spelled out beyond the on-site label, candidates should confirm expectations directly with the employer, as day-to-day flexibility, if any, is not stated in the listings.

Make your application specific to the work

  1. Review the role's specialism These postings cover distinct disciplines โ€” embedded, cloud, network, application, and enterprise security โ€” so read each description carefully to confirm the technical domain matches your background before applying.
  2. Check seniority and experience bands Postings range from a new-graduate entry point through to staff and lead levels; the advertised pay ranges and stated years of experience differ substantially, so verify the level fits your profile.
  3. Prepare relevant technical evidence Given the frequency of Python, cloud platforms, and infrastructure tooling across descriptions, be ready to discuss concrete examples of work in whichever of those areas the specific role emphasises.
  4. Confirm on-site expectations early Because nearly all roles are listed as on-site in Sunnyvale, clarify exact attendance requirements โ€” including any data-centre obligations โ€” with the employer before or at the screening stage.
