Job summary

Heron Power Inc. is seeking an experienced Senior/Staff Embedded Software Engineer to lead the embedded firmware platform. You will shape architecture, enforce quality, and deliver firmware across device-level systems, from RTOS to bootloaders and diagnostics.

You’ll collaborate with firmware, controls, and cloud teams to own the device brain, drive architecture decisions, and mentor others while shipping reliable, high-performance software for power conversion products.

Qualifications

• 5+ years of embedded firmware development with shipped product.
• Expert-level embedded C/C++.
• Deep experience with RTOS, bootloaders, and low-level hardware drivers.
• Experience working within large embedded system architectures.
• Familiarity with firmware CI/CD and automated testing frameworks.
• Strong hardware debugging skills (oscilloscope, logic analyzer).
• Collaborative mindset and interest in growing other engineers.

Responsibilities

• Define and drive the architecture for embedded firmware across Heron products.
• Participate in design reviews, identify systemic risks, and help set coding standards.
• Serve as a technical resource and mentor for other embedded engineers.
• Collaborate across firmware and hardware for system-level decisions.
• Design and implement RTOS-based firmware for high-performance power conversion.
• Build low-latency control infrastructure, telemetry, and key drivers (PWM, ADC).
• Evaluate MCUs/SoCs for new platforms and ensure safety-critical firmware.
• Design bootloaders, secure firmware architecture, and update mechanisms.
• Implement on-device logging, diagnostics, and observability tooling.
• Define device-side interfaces and data models; improve tooling and validation pipelines.

Job description

What to Expect

Heron Power is a startup building cutting-edge power electronics for the 21st-century grid. We aim to debottleneck the growth of electricity generation and consumption with scalable, innovative, and cost-effective hardware solutions, accelerating the electrification of everything. Our first goal is to build better converters (inverters & rectifiers) to connect large-scale renewables, storage, and loads to the grid. Heron’s leadership team is made up of seasoned veterans who have designed and shipped gigawatts of power conversion products. We believe no one person knows everything. We learn together, build together, and solve hard problems from first principles. You’ll work in a fast-moving, deeply technical environment where ownership and impact are real.

Job Overview

As a Senior/ Staff Embedded Software Engineer, you will be a key technical force behind Heron's embedded firmware platform — driving architecture decisions, raising the bar on quality and reliability, and delivering high-impact firmware across the full stack of our power conversion products. You’ll work closely with the firmware, controls, and cloud teams to define how our converters are operated and monitored at the device level: from RTOS architecture to bootloaders, diagnostics, safety infrastructure, and production firmware processes. This role blends deep hands on engineering with system architecture and technical leadership.

Why This Role Is Different

You’ll work at the heart of the team building the device brain — close enough to the metal to matter, with enough scope to shape how the platform grows. You’ll drive meaningful architecture decisions, raise the technical bar, and partner across firmware, controls, and cloud to ship a complete solution. If you want real ownership over hard problems — and enjoy pulling others up alongside you — you'll thrive here.

How You Will Contribute

Architecture & Technical Leadership

• Contribute to and drive the architecture for embedded firmware across Heron products
• Participate actively in design reviews, identify systemic risks, and help establish coding standards and engineering practices
• Serve as a technical resource and informal mentor for other embedded engineers
• Collaborate across firmware and hardware boundaries on system-level decisions

Real-Time & Control Firmware

• Implement and improve RTOS-based firmware for high-performance power conversion
• Design and build low-latency control infrastructure, fault management, telemetry, real-time scheduling, and key drivers and peripherals (PWM, ADC, communications, etc.)
• Evaluate and select microcontrollers/SoCs for new platforms
• Build safety-critical and high-reliability firmware systems

Device Infrastructure

• Design bootloaders, secure firmware architecture, and update mechanisms
• Implement logging, diagnostics, tracing, and observability tools on-device
• Define device-side communication interfaces and data models

Quality & Tooling

• Define unit, integration, and hardware-in-the-loop testing strategies
• Improve developer tooling and validation pipelines

What You Will Bring

Must-Have Requirements

• 5+ years of embedded firmware development with shipped product
• Expert-level embedded C/C++
• Deep experience with RTOS, bootloaders, and low-level hardware drivers
• Experience working within and contributing to large embedded system architectures
• Familiarity with firmware CI/CD and automated testing frameworks
• Strong hardware debugging skills (oscilloscope, logic analyzer, etc.)
• Collaborative mindset and interest in growing other engineers

Nice-to-Haves

• Real-time control systems or power electronics experience
• Safety-critical or high-reliability firmware (IEC 61508, UL1998, etc.)
• Secure boot and device security experience
• Experience integrating embedded systems with cloud/IoT platforms
• FPGA or ASIC familiarity
• Production manufacturing and field support experience

Heron Power provides competitive compensation (salary and equity) and benefits. The salary for this role ranges from $140,000 to $220,000 per year.
