Software Engineer, Energy Storage

Essential Duties:

You will be an early member of the Redwood Energy engineering team, taking a hands-on role in the design, development, and integration of second-life battery-based energy storage systems. This position focuses on developing robust and reliable system software for the Site Controller that serves as the central nervous system for the product. The role involves designing and implementing containerized services for networked device management, site level controls orchestration, time series data management, and system diagnostics.

The ideal candidate is highly self-driven, adaptable to a startup environment, and eager to take on novel technical challenges. If you’re excited about working in a dynamic, fast-paced setting within a new department at Redwood, we want to hear from you!

If necessary, the job level will be adjusted to suit the applicant’s experience and responsibilities.

Responsibilities will include:

• Design and implement a scalable and resilient system architecture for the Site Controller, leveraging containerization technologies like Docker and Kubernetes

• Architect and build a flexible control platform that seamlessly coordinates multiple hardware assets and integrates with optimization algorithms to enable intelligent energy arbitrage, grid services, and grid-scale renewable energy integration

• Collaborate with backend and UI engineering teams to architect sophisticated customer and operations interfaces, designing robust IoT data management solutions that provide real-time visibility into system performance, energy flows, and operational metrics across distributed energy storage deployments

• Create SIL and HIL test frameworks for integration testing of the product

• Collaborate with firmware engineers to ensure seamless integration between the site controller and distributed microcontrollers

• Collaborate with modeling and systems engineers to implement control algorithms for the site

• Produce excellent software documentation

• Troubleshoot and resolve system issues in a timely manner

• Contribute to a collaborative, fast-paced startup culture, where every team member plays a crucial role in achieving company milestones

Desired Qualifications:

• BS or MS in Computer Science, Electrical Engineering, or a related field and 2+ years of experience developing application software for hardware systems

• Strong proficiency in Python, Rust or Go

• Experience profiling and optimizing code running on multi-core targets

• Familiarity with network protocols (TCP/IP, CoAP, MQTT, etc.)

• Experience with time series databases (e.g InfluxDB, Prometheus) and data visualization tools

• Familiarity with IoT and embedded systems

• Experience with Linux system administration and containerization technologies (Docker, Kubernetes)

• Experience implementing a firmware OTA pipeline from cloud through downstream controllers is a plus

• Experience with machine learning, adaptive control, model predictive control or other optimization techniques is a plus

• Excellent problem-solving and debugging skills

• Strong communication and collaboration skills

Physical Requirements:

• Ability to perform the essential job functions consistent safely and successfully with the ADA, FMLA and other federal, state and local standards, including meeting qualitative and/or quantitative productivity standards.

• Ability to maintain regular, punctual attendance consistent with the ADA, FMLA and other federal, state, and local standards

Working Conditions:

• Environment, such as office or outdoors

• Ability to work in challenging working conditions which may include exposure to noise, dust, chemicals, and temperature extremes, while protected by PPE, for extended periods of time.

• Essential physical requirements, such as climbing, standing, stooping, or typing

• Occasional work weekends, nights, or be on-call as a regular part of the job

• Occasional travel requirements
