About the role
Option 1: Edge Testing Engineer Role Overview We are looking for an Edge Testing Engineer to validate the performance, reliability, and communication interfaces of our edge-computing devices. You will be responsible for ensuring our distributed edge systems communicate seamlessly across various networks, protocols, and real-world deployment scenarios.
Key Responsibilities:
Develop and execute automated test scripts using Python and pytest tailored for edge device validation. Validate core connectivity features, including Ethernet, Bluetooth, and CAN protocols. Design, build, and maintain physical test fixtures and test benches to simulate edge environments and test fixture hardware. Troubleshoot end-to-end communication failures, analyze packet data, and debug hardware-software interactions using logic analyzers. Write comprehensive test cases, execute test plans, and track issues to maintain high product quality.
Required Qualifications:
Proven experience in Python scripting and pytest frameworks. Hands-on experience testing edge devices, IoT hardware, or distributed systems. Solid working knowledge of communication protocols (Ethernet, Bluetooth, CAN). Experience using lab debug tools such as logic analyzers and protocol debuggers. Strong troubleshooting, analytical, and test case design skills.
Nice-to-Haves:
Experience measuring and expanding test coverage metrics for edge software. Background in automated test fixture integration. Option 2: Embedded Testing Engineer Role Overview We are seeking an Embedded Testing Engineer to focus on low-level firmware validation, hardware-software integration, and system-level debugging. In this role, you will work closely with firmware engineers to ensure our microcontrollers and embedded platforms operate with maximum stability and performance.
Key Responsibilities:
Design and implement embedded test frameworks and automation scripts using Python and pytest. Perform thorough low-level functional, regression, and stress testing on custom embedded hardware. Collaborate with hardware teams to design and build custom test fixtures for board-level validation. Analyze firmware behavior, trace memory/timing issues, and debug board signals using logic analyzers, oscilloscopes, and multimeters. Create detailed test cases and document requirements to ensure robust firmware releases.
Required Qualifications:
Strong experience in embedded software or firmware testing environments. Proficiency in Python and pytest for test automation. Experience with hardware debugging tools, particularly logic analyzers and oscilloscopes. Ability to read schematics, understand microcontroller datasheets, and troubleshoot hardware/firmware boundaries. Analytical mindset with a strong track record of writing and executing rigorous test cases.
Before you apply
Applying takes about a minute. These four things decide how fast it moves after that.
Your profile is current
It's what we read first. Occupations, seniority and locations matter more than a long history.
Two examples you can talk through
Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.
A number in mind
What you're on now and what would make you move. We negotiate better when we know both.
Your notice period
Employers plan around it, and it's the question that stalls offers most often.
Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
