Firmware Developer (Hiring Immediately)

Location: Maple Heights, Ohio 44137 (In office)

Employment Type: Full Time

Overview: We are seeking a skilled C++ Firmware Engineer with hands-on experience in embedded systems and a strong understanding of vending machine technologies. This role involves developing, maintaining, and optimizing firmware that powers vending machines, including payment systems, inventory tracking, and hardware integration.

Key Responsibilities: Design, develop, test, and maintain embedded firmware in C++ for vending machine systems Interface with hardware components such as bill validators, coin mechanisms, card readers, touchscreens, and IoT modules Implement and debug communication protocols (e.g., MDB, UART, SPI, I2C) commonly used in vending environments Collaborate with electrical, mechanical, and software engineers to ensure seamless integration Optimize system performance, memory usage, and power consumption Develop and maintain diagnostic tools and firmware update mechanisms (OTA or wired)Troubleshoot field issues and provide root cause analysis Ensure compliance with industry standards and payment security requirements (e.g., PCI, EMV where applicable)

Required Qualifications: Bachelor's degree in Computer Engineering, Electrical Engineering, or related field (or equivalent experience)3+ years of experience in embedded firmware development using C++Strong understanding of real-time operating systems (RTOS) or bare-metal systems Experience working with microcontrollers (e.g., ARM Cortex-M, AVR, PIC)Familiarity with vending machine protocols such as MDB (Multi-Drop Bus) & DEXExperience integrating payment systems (cash and cashless)Proficiency with debugging tools (oscilloscopes, logic analyzers, JTAG debuggers)Strong problem-solving skills and attention to detail

Preferred Qualifications: Experience with IoT connectivity (Wi-Fi, LTE, Bluetooth) in embedded devices Knowledge of Linux-based embedded systems Familiarity with cloud integration for telemetry and remote management Experience in low-power design and optimization Understanding of cybersecurity best practices for embedded systems Nice-to-Have Skills Experience with vending machine management systems (VMS)Understanding or familiarity with DEX protocol Understanding or familiarity with MDB communication protocol Knowledge of telemetry, remote monitoring, and predictive maintenance
