Senior Engineer - SQA

The Role

As a Senior SDET (MCU & Bootloader Testing) at Silicon Labs, you will play a pivotal role in defining and upholding quality standards for our embedded wireless and MCU products, with a strong focus on bootloader and firmware reliability. You'll design and execute robust functional, negative, performance, and stress tests, build scalable automation frameworks, and integrate them into a continuous integration (CI) ecosystem to ensure fast, repeatable validation across releases.

In this role, you'll also work closely with cross-functional teams to debug complex system issues, validate real-world use cases, and help ensure customers experience stable and reliable upgrades, deployments, and platform behavior.

Meet the Team

You'll be part of Silicon Labs Embedded SQA/SDET organization, collaborating closely with firmware developers, DevOps, customer support, sales teams, and Field Application Engineers (FAEs). The team's mission is to strengthen product quality and release confidence by building a strong foundation of automation, test infrastructure, and deep embedded validation—especially in critical areas like bootloaders, firmware update flows, peripheral drivers, and MCU/RTOS behavior.

This team operates in a highly cross-functional environment where we not only test what we build—but also help emulate and troubleshoot real customer environments and edge cases.

Responsibilities

• Design and execute functional, negative, performance, and stress tests for Silicon Labs MCU and embedded wireless products.
• Drive comprehensive validation of bootloader and firmware features, including upgrade/regression scenarios and failure handling in real embedded environments.
• Build and maintain automation test suites that run regularly as part of CI infrastructure to enable continuous quality signals.
• Implement automated tests based on test plans, with strong emphasis on repeatability and scalability.
• Investigate test failures and anomalies in continuous integration systems, perform triage/root-cause analysis, and partner with developers to resolve issues.
• Work closely with development teams to debug problems found during the test cycle, including low-level and system integration issues.
• Develop custom embedded applications in C/Embedded C for test enablement, peripheral validation, and targeted coverage.
• Build, manage, and maintain a distributed test network (hardware test infrastructure) to support broader regression and platform coverage.
• Simplify and automate product deployments and platform changes, improving stability and efficiency of test environments.
• Increase team productivity by identifying opportunities to automate repetitive tasks, scripting workflows, and eliminating process waste.
• Support customer success by reproducing and resolving customer issues through close collaboration with customer support teams.

Requirements

• 4-7 years of relevant industry experience in embedded testing / SDET / QA automation.
• Proven experience in bootloader and firmware test automation (designing, executing, and automating validation).
• Strong hands-on experience in bare-metal environments and embedded bring-up/testing practices.
• Working knowledge of RTOS-based systems (e.g., uC/OS, FreeRTOS, or similar).
• Solid understanding of low-level drivers and peripherals, including SPI, UART, I2C, and related MCU interfaces.
• Strong programming skills in C / Embedded C / C++ and Python, plus scripting (e.g., Shell/Bash).
• Experience developing automated tests using frameworks such as Pytest (or equivalent).
• Familiarity working across Windows and Linux development/test environments.
• Strong working knowledge of Git for version control and collaboration.
• Exposure to CI/CD practices; Jenkins experience preferred.
• Familiarity with Docker (preferred) for test environment packaging and repeatable setups.
• Strong communication and collaboration skills; ability to work effectively in a small, cross-functional team.
• Conversational fluency in English.

Nice to have / Plus:

• Experience building or operating distributed hardware test infrastructure (hardware farms / test networks).
• Exposure to FPGA environments (debug/validation support).
• Strong practical experience applying CI techniques for embedded systems at scale.

Experience with artificial intelligence (AI) powered tools and technologies used to enhance productivity, analysis, and decision-making
