Senior Engineer (IoT Platform Development)

The Devices Team is responsible for the creation and lifecycle management of IoT devices enrolled in EnergyHub programs used to balance the power grid. The team plays a critical role in ensuring the scalability and flexibility of our future by creating a core platform that enables other internal teams to build new features and functionality quickly.

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

As a senior engineer, you support our mission by helping drive major initiatives, providing expertise and guidance from past industry experience, and autonomously developing 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.
• Help drive the transition from a monolithic architecture to a microservices-based approach, ensuring scalability, maintainability, and improved system resilience.
• Lead technical initiatives and provide data modeling, contract definition, and API development.
• Develop front and back end 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).
• Mentor and support other engineers, fostering a strong technical culture of respect, open communication, and collaboration.

Required Skills and Experience: What you need

• 7+ years of professional software engineering experience.
• Strong full-stack development experience, including frontend, backend, and relational database modeling and development.
• Proficiency in React and Java (preferably Java 11+).
• Experience with web services, gRPC/RESTful APIs, and contract-driven development.
• Ability to operate independently, help provide technical vision, and guide the team toward scalable solutions.
• Strong problem-solving skills, capable of balancing multiple use cases while enabling flexibility.
• Proven expertise in building dynamic, responsive user interfaces using React and TypeScript.
• Demonstrated proficiency in leveraging AI tools in development and testing to accelerate delivery and enhance code quality.
• Strong communication skills, with an emphasis on cross-functional collaboration and working on challenging technical problems.

Preferred Skills and Experience: Nice-to-haves

• Experience with PostgreSQL, Asynchronous messaging (SNS/SQS, RabbitMQ), MongoDB, AWS, Datadog, 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.
• Experience or familiarity with the energy industry.
