Senior QA Embedded Engineer

About Vammo

Vammo is building an accessible, resilient, and scalable clean energy network for emerging megacities, starting in Latin America. By combining electric motorcycle subscriptions with a rapidly expanding battery swap infrastructure, we make clean transportation affordable and reliable for the millions who keep cities moving.

Founded in 2022 and headquartered in São Paulo, Vammo has raised $100M from top-tier investors across the globe. Our founders and team represent an incredibly diverse and international group that is built of former executives coming from Tesla, Uber, Rappi, iFood, Loggi, Niu, Jump and others. We are all deeply motivated by the mission to decarbonize Latin America while simultaneously reducing costs for one of the region’s most vulnerable populations.

The next wave of mobility innovation will come not from San Francisco, but from São Paulo. Our operations will soon expand from Sao Paulo to cities across Brazil, Mexico, and Colombia, proving that real climate impact and transformative business models can be built first where the need is greatest.

About the Role

We are looking for a Senior Embedded Systems Test Engineer to join our Hardware Engineering team. This role is key to support this team, validating and debugging all Vammo’s hardware ecosystem, including IoT devices, electronics modules for vehicles and battery swap framework.

What you’ll do

• Develop and maintain automated test plans, test cases and scripts to validate hardware products from development through manufacturing;
• Translate product requirements into test plans and test cases;
• Work closely with hardware/firmware engineers to identify the needed tests during development;
• Validate a firmware release according to the product requirements;
• Work closely with software team to validate a seamlessly API integration with hardware, involving testing backoffice tools and mobile applications;
• Collaborate with development team to create, validate and deploy test solutions in the manufacturing process (factory test firmware, test jigs, etc);
• Debugging and troubleshooting using embedded debug tools;
• Communicate test progress and test status to key stakeholders clearly;

What we’re looking for

• Bachelor’s or Master’s in Electrical Engineering, Computer Engineering, Electronics, or a related field. Equivalent hands-on testing embedded systems may also be considered;
• Experience with serial protocols (CAN, RS485, RS232) and hardware peripherals (USART, I2C, SPI, GPIO);
• 6+ years in testing embedded systems, ideally in automotive, mobility, or other mission-critical hardware;
• Skilled at Python programming for test automation;
• Experience with HIL tools;
• Experience with stress, performance and security tests;
• Proven ability to debug complex firmware/electronics integration issues;
• Comfortable working in fast-paced, ambiguous environments where firmware is critical to product launch. Startup experience is a plus;
• Fluent or advanced English, speaking, reading and writing (we have constant discussions in English with all the team);
• Nice to have:
• Experience with C or C++ languages to help on unit testing;
• Hands-on experience with test automation frameworks: Robot framework or Pytest for embedded systems;
• Familiarity with wireless communication protocols (LTE, BLE, WiFi), cloud/IoT integration (MQTT and protobuff) and Linux network layers.

What You’ll Get

• A front-row seat at one of Latin America’s most ambitious hardware and climate tech startups, backed by world-class investors.
• A mission-driven environment where every decision contributes to decarbonizing mobility and empowering low-income workers.
• Freedom to take on as much responsibility as you can handle — and grow faster than anywhere else.
• A collaborative, fast-paced, and purpose-driven team that loves to build real things in the real world.
• Competitive compensation and equity package.
• Health insurance and benefits.
