Jobs at About You in United States

An innovative company in the intelligent sensing space is seeking an Embedded Systems Engineer to join their growing development team. The organization is focused on building scalable, ultra-low-power embedded devices that transform acoustic signals into real-time insights — with current applications in manufacturing, energy efficiency, and smart infrastructure, and future expansion into defense, space, and urban systems.

This is a hands-on engineering role ideal for individuals passionate about embedded software, hardware integration, and working on meaningful, next-gen sensor solutions.

Key Responsibilities :

Firmware Development & Optimization

• Architect, develop, and test embedded firmware for sensor and gateway platforms
• Implement low-level interfaces and communication protocols (SPI, I²C, UART, CAN)
• Optimize code for power efficiency, reliability, and real-time performance across challenging environments

Hardware Integration & Field Testing

• Work closely with electrical, signal processing, and mechanical engineers to integrate systems
• Support prototyping and iterative development of hardware / software integration
• Validate device functionality through lab and in-field testing
• Lead debugging with tools such as oscilloscopes, logic analyzers, JTAG / SWD
• Prepare technical documentation, test procedures, and validation reports

Cross-Functional Collaboration

• Collaborate across disciplines to align embedded systems with broader product goals
• Participate in best practice development, team knowledge sharing, and technical reviews
• Engage with external labs or testing partners for certification and system validation

Your Profile :

Required Qualifications :

• Degree in Electrical / Computer Engineering or a related technical field
• 2+ years experience in embedded systems development
• Proficiency in C / C++ for microcontroller environments
• Familiarity with RTOS, low-level hardware debugging, and version control (e.g., Git)
• Understanding of DSP fundamentals and hardware-software interfacing
• Must have valid EU work authorization

Preferred Qualifications :

• 4+ years of experience in embedded software across IoT, industrial, or automotive sectors
• Advanced degree (Master’s or PhD) in a relevant technical discipline
• Experience with low-power design and energy-efficient firmware
• Familiarity with wireless protocols : LoRa, Wi-Fi, Bluetooth, Cellular
• Knowledge of hardware certification (e.g., CE, FCC, IP ratings)
• German language skills are a plus

If you're excited about working on next-generation embedded systems with real-world impact, we’d love to hear more about what drives you and how your background aligns with this opportunity.
