Software Development Engineer Testing I

Software Development Engineer in Test (SDET) - Automation & HIL Systems

Location: Needham, MA (Hybrid)

About the Role

As a Software Development Engineer in Test (SDET) at SharkNinja, you will design, develop, and operate advanced test automation frameworks and Hardware-in-the-Loop (HIL) systems to accelerate the validation of embedded software across our connected product portfolio. You'll collaborate closely with cross-functional engineering teams-including software, controls, and hardware-to create robust test environments that ensure product reliability and performance at scale.

Responsibilities

• Design, develop, and maintain automated test frameworks, tools, and test benches for embedded software verification and validation.
• Develop and operate HIL test setups integrating sensors, actuators, and control modules to simulate real-world operating conditions.
• Collaborate with embedded software, controls, and systems engineers to define test requirements and implement end-to-end validation workflows.
• Build, configure, and maintain test automation infrastructure supporting continuous integration and deployment (CI/CD) pipelines.
• Automate test execution and reporting, improving coverage and reducing manual effort.
• Develop test scripts and utilities using Python, MATLAB/Simulink, or LabVIEW to interface with mechatronic components (switches, relays, motor drivers, etc.).
• Integrate testing with source control and CI tools (e.g., Git, Jenkins, Azure DevOps).
• Participate in code reviews, debugging, and root-cause analysis of test failures to improve product robustness.
• Support hardware bring-up and system-level validation, ensuring that software interacts safely and reliably with physical systems.

Qualifications

• Bachelor's or Master's degree in Electrical Engineering, Computer Science, Mechatronics, or related field.
• 2+ years of experience in software test automation or embedded systems testing.
• Experience with test automation frameworks and scripting languages (Python, MATLAB, LabVIEW, etc.).
• Strong understanding of software/controls development and the interaction between software and mechatronic systems (sensors, relays, actuators, motor controllers).
• Experience with CI/CD tools (Jenkins, GitLab CI, Azure DevOps) and version control systems (Git).
• Familiarity with embedded software testing methodologies, HIL systems, and real-time simulation environments.
• Working knowledge of communication protocols (CAN, I2C, SPI, UART, BLE, Wi-Fi) and data acquisition systems.

Preferred Qualifications

• Experience building HIL test setups or using real-time testing platforms (e.g., dSPACE, Speedgoat, NI PXI).
• Background in model-based development with MATLAB/Simulink and test automation integration.
• Experience in consumer product development or IoT/connected devices.
• Familiarity with test management tools, automated reporting, and metrics tracking.
