Job description

Urgent position of Embedded Tester Engineer

Location : San Jose, CA (On-site)

The Opportunity

Staff Software Test Engineer – who is less of a “script runner” and more of a tool builder.

Primary Focus

Simulator Development (C#), Automation (Squish), & Firmware/Hardware Validation

Responsibilities

• Lead the design, development, and enhancement of the CLIENTS System Simulator using C#. Build the virtual environment that mocks hardware behavior to test firmware and software logic.
• Develop and execute automated test scripts using Squish (GUI automation) and Python.
• Perform a mix of automated and manual testing. Manually execute complex test cases where automation isn’t yet feasible, ensuring total system safety.
• Validate the interaction between high-level software and low-level firmware/hardware components via the simulator.
• Draft verification protocols and manage requirements/defects using JAMA and Jira, ensuring strict adherence to FDA QSR and IEC 62304 standards.
• Integrate simulator tests into the Continuous Integration pipeline (Jenkins/GitHub) to catch regressions early.

Must-Have Skills (Non-Negotiables)

• C# Expertise: Minimum 5+ years of hands‑on development experience in C#. Comfortable writing complex object‑oriented code, not just editing scripts.
• Python Experience: Minimum 2+ years of scripting experience (used for glue code and automation support).
• Automation Tools: Proven experience with Squish (preferred), WinAppDriver, or similar GUI automation tools.
• Flexibility: Willingness to perform manual testing when necessary to ensure product quality.

Preferred Qualifications

• Medical Device Background: Solid understanding of FDA QSR (21 CFR Part 820), ISO 13485, and the V&V (Verification & Validation) process.
• Experience testing firmware or embedded systems via simulation.
• Experience with JAMA for requirements management.
• Background in robotics or complex electromechanical systems.
