You’ve shipped firmware that runs in the real world. You know that speed without structure creates technical debt, and you’ve built the habits to prevent it. You care about the craft, the architecture, and the product it powers. You bring 3+ years of embedded firmware development, primarily in C/C++. You’ve worked hands‑on with architectures like STM32, built features from requirements through production, and extended existing codebases without breaking what’s already there. Communication protocols like I2C, SPI, and UART are second nature. You’re comfortable in both RTOS‑based andbare‑metal environments, and you debug embedded systems with patience and precision.You write clearly. Technical documentation, status updates, async communication. Your teammates always know where things stand. You hold a Bachelor's or Master’s degree in Computer Science, Electrical Engineering, or a related field (EQF 6+). You’re based in the Netherlands or able to relocate independently, and you’re eligible to work here without visa sponsorship (we’re not registered IND sponsors).Worked with TouchGFX or other embedded GUI frameworks. Used FreeRTOS in production. Handled asynchronous RS‑485 communication between microcontrollers. Built or improved embedded development toolchains and workflows. Set up testing frameworks and test automation for firmware. Shipped software for appliances or consumer products. Helped a hardware company grow from 20 to 100+ people while keeping engineering practices sharp: version control discipline, code reviews, documentation, structured releases.Why Aquablu?

Benchmark salary based on experience (depending on experience). Beautiful and bright office in Amsterdam (Houthavens). Monthly team nights (karaoke, game night, bootcamp etc.). Be part of an exciting growth phase of a scaling company. Endless amount of our very own flavoured water! You will be part of a young, fun and ambitious team that aims to change the way people consume water.
