Embedded Firmware Engineer

Embedded Firmware Engineer 

Overview 

We’re looking for a full-time remote firmware leader to own embedded software for a renewable energy inverter. You will be responsible for owning the design of firmware for real-time control, communication, telemetry and test automation. This role works closely with hardware and test engineers to define requirements, build robust test procedures, and ship production-grade firmware.  

 Key Responsibilities 

• Own firmware technical roadmap, architecture decisions, and delivery for a multi-controller embedded system.  
• Lead planning, estimation, prioritization, and execution of firmware workstreams across new features, validation, and field issues.
• Define firmware requirements and test procedures to validate new features. 
• Develop and maintain firmware on Microchip PIC16 & PIC32 MCU’s using MPLAB X, MCC and X32 toolchain.
• Deliver safe and deterministic behavior for closed loop control systems.  
• Build and maintain firmware validation tooling and automation.
• Drive coding standards and best practices across code reviews, documentation, testing, and long-term maintainability 

Required Skills & Experience  

• A bachelor's degree in Electrical & Electronic / Software Engineering or equivalent.
• Strong firmware experience working with embedded C & microcontrollers for 3+ years. 
• Experience with communication protocols SPI, UART, I2C & peripherals such as ADCs & PWMs. 
• Proven ability to debug complex issues.  
• Ability to define system behavior using state diagrams and translate them into deterministic embedded firmware.
• Ability to read electrical schematics, datasheets, and functional diagrams.
• Expertise in control theory, feedback/feedforward loops, and frequency response.
• Proficiency with Git workflows (branching, reviews, releases) 

Nice To Haves 

• Experience with TCP/UDP networking and Wi-Fi module integration in embedded systems.
• Jenkins or comparable CI/CD release pipelines.
• Experience using JIRA for backlog, requirements, and feature tracking.
• Experience with Python and scripting languages.
• Knowledge of higher-level programming languages and experience using AWS cloud services.
• Understanding of Grid Technologies and renewable energy system.
• Experience with Power Electronics, oscilloscopes, and digital multimeters.
