Embedded Software Test Engineer – Cybersecurity

Job Title: Embedded Software Test Engineer – Cybersecurity IV&V.

Location: Plymouth, MN (On-site).

Employment Type: Contract (W2 through Zip Staff — No C2C or 1099).

Zip Staff is seeking an Embedded Software Test Engineer to perform independent verification and validation of cybersecurity enhancements on a hydraulic mobile-valve controller at a global fluid-power manufacturer.

You will verify secure boot, firmware authentication, access control, and secure update on a Texas Instruments TMS
320F2809 (C2000) and produce evidence for EU Cyber Resilience Act technical documentation. This is a hands-on embedded security test seat on target hardware — not a feature-development role and not an IT security role.

• Design and execute test plans to independently verify cybersecurity enhancements on the embedded controller.
• Evaluate secure boot, firmware authentication, access-control models, and secure over-the-air / in-field update.
• Produce verification plans, test cases, trace matrices, and evidence for the EU Cyber Resilience Act and related frameworks.
• Use JTAG debuggers, oscilloscopes, and logic analyzers for low-level verification, fault injection, and hardware-in-the-loop testing on the target.
• Develop Python scripts for security regression, hardware interfacing, and test-output parsing.
• Review Embedded C firmware and run static analysis against secure-implementation issues.

• 5+ years in embedded software verification, test engineering, or embedded security validation.
• Bachelor’s in Electrical Engineering, Computer Engineering, Computer Science, or a related field.
• Hands-on firmware development or test on Texas Instruments C2000 (TMS
  320F2809 or a similar TI DSP/MCU).
• Secure boot, cryptographic signature verification, key management, access control, and secure firmware flashing.
• Evidence generation for EU CRA
  , IEC 62443, or ETSI EN 303 645.
• Embedded C for firmware review and Python for test automation.
• JTAG debuggers, in-circuit emulators, logic analyzers, and protocol analyzers.
• Ability to work on-site in Plymouth, MN.
• Must be legally authorized to work in the United States without sponsorship now or in the future.

• Hydraulic, mobile-equipment, or industrial-controller test.
• Fault injection and HIL on a production controller.
• Prior CRA or IEC 62443 technical-file contribution.

• Health Insurance.
• Dental Insurance.
• Vision Insurance.
• 401(k).
• 401(k) matching.
• Paid time off.
• Referral Program.
