Intermediate / Sr. Embedded Systems & Firmware Engineer - HYBRID

Apply Description AEM (Advanced Environmental Monitoring) is the global leader in innovative mission critical weather, wildfire and water monitoring and intelligence solutions. We aim to be the world’s essential source for environmental insights – enabling decisive action and positive outcomes for our customers and their constituents. Our family of innovators offers world-class hydrometeorological technologies and services, including sensors, dataloggers, telemetry, and advanced analytics and software. Our technology and services empower the communities and organizations to survive – and thrive – in the face of escalating environmental risks. Van Essen Instruments, an AEM brand, was founded in 1938 by Cornelis van Essen in Delft, Netherlands. In the early 1990s, Van Essen began to offer standard water related equipment such as standalone dataloggers, which used external sensors and flow meters for open channels. We also offer telemetric solutions. Since the deployment of the first Diver, Van Essen sold over 200,000 dataloggers worldwide. Its commitment to quality and performance has established Van Essen Instruments as one of the premier brands in the industry. Van Essen has its headquarters in the Netherlands (Delft), and sales locations in Canada and the US. For more information, please visit www.vanessen.com . We're looking for a hands-on engineer to take ownership of firmware and embedded systems work across our connected device portfolio — from initial concept through production-ready, certified products. You'll work across hardware, firmware, mechanical design, and cloud connectivity, and you'll be the technical anchor ensuring our products are secure, compliant, and manufacturable. You'll also act as the primary technical liaison between Van Essen (Delft) and our sister site, Lambrecht Meteo (Göttingen, Germany), on hardware, testing, security, and certification alignment. This role suits an engineer who likes working across disciplines rather than staying in one lane — someone equally comfortable reviewing a schematic, writing firmware, debugging a prototype on the bench, and walking a certification body through a security design. Job Responsibilities: Firmware & Embedded Systems Own firmware design, implementation, and maintenance across our connected device portfolio — bootloaders, data acquisition, telemetry interfaces, and OTA update mechanisms. Conduct board bring-up, debugging, and hardware validation for new and existing products. Integrate cryptographic mechanisms (AES, ECC) and evaluate the transition to certificate-based authentication and mutual TLS (mTLS) for end-to-end device security. Review electrical schematics and mechanical designs, providing system-level input so hardware, firmware, and cloud connectivity work together correctly in the finished product.
