Software Engineer II, Devices

The Devices Team is responsible for the creation and lifecycle of IoT devices enrolled in EnergyHub programs used to balance the power grid and contribute to the overall EnergyHub mission of creating a carbon-free distributed energy future. The team will play a critical role in ensuring the scalability and flexibility of our future by abstracting partner and client-specific complexities to enable other internal teams to build new features and functionality quickly. 

This is an opportunity to join a highly energized team of engineers to define and develop key concepts, solve complex challenges with real-world constraints, and have a positive impact on our climate future. We are focused on migrating from a monolithic to a microservices architecture and delivering well-defined contracts to the broader organization. The primary focus is to integrate any Distributed Energy Resource (DER) type into our platform in a way that enables multiple use cases without compromising quality and scalability. 

As a Software Engineer II, you will support our mission by helping define and develop high-quality solutions that balance multiple constraints while ensuring long-term flexibility. 

Main Responsibilities: What you'll do 

• Design and implement core platform features that solve for multiple constraints and use cases. 
• Support the transition from a monolithic architecture to a microservices-based approach, ensuring scalability, maintainability, and improved system resilience. 
• Contribute to data modeling, contract definition, and API development. 
• Develop backend as well as frontend solutions, ensuring well-structured, high-quality code with automated testing. 
• Collaborate cross-functionally with product managers, internal engineering teams, and stakeholders to drive high-impact projects. 
• Work within real-world constraints to develop creative solutions that maintain platform flexibility and scalability. 
• Contribute to best practices for CI/CD, data modeling, and iterative development (e.g., PoCs, rapid prototyping, milestone-based execution). 
• Support other engineers, fostering a strong technical culture of respect, open communication, and collaboration. 

Required Skills and Experience: What you need

• 3+ years of professional software engineering experience, with a primary focus on backend systems, exposure to frontend development, and proficiency in relational database design. 
• Proficiency in Java (preferably Java 11+) and experience with at least one scripting language (e.g., React). 
• Experience with web services, gRPC/RESTful APIs, and contract-driven development. 
• Ability to operate independently with little supervision. 
• Strong problem-solving skills, capable of balancing multiple use cases while enabling flexibility. 
• Frontend experience with Typescript and React and the ability to contribute to UI development as needed. 
• Experience and familiarity with AI coding tools. 

Preferred Skills and Experience: Nice-to-haves 

• Experience with PostgreSQL, RabbitMQ, MongoDB, AWS, and Robot Framework. 
• Familiarity with CI/CD pipelines and modern software development practices. 
• Proven ability to deliver high-quality, iterative value while maintaining execution speed.
• Strong communication skills, with an emphasis on cross-functional collaboration and working on challenging technical problems. 
• Experience or familiarity with the energy industry and energy management.
