• Ability to work with minimal supervision and solve complex technical issues.

• Excellent attention to detail and structured approach to documentation.

Desirable:

• Experience working to DO-178C, SIL-4, or similar safety integrity standards.

• Familiarity with tools such as LDRA, RAPITA, or SCADE.
