Senior Full Stack Software Engineer

We are seeking a remote, full-time Senior Full Stack Software Engineer with 5+ years of software development experience. Candidates must have a strong background in React.js and either Golang, Node.js, or Java, with a strong desire to adopt Golang as the primary backend technology.
In this position, you will play a foundational role in building the core platform that enables power utilities to shift from decades-old legacy systems into an AI-native future. Candidates must bring working proficiency with AI tools and APIs to ensure seamless integration of intelligent functionality into the client's products.
This role requires strong coding fundamentals, system design capability, and the mindset of a builder who thrives in a startup environment. You will work in small, agile teams reporting directly to the CTO, collaborating closely with AI engineers, security leaders, and product managers. Together, you will build and deliver AI-native services delivered at startup speed.
Our client is building an AI-centric operating system for utilities. It harnesses AI at the enterprise level to better orchestrate customer delight, facilitate power optimization, improve the health of the grid, and unlock flexibility at scale. Funded by a strategic industry partner and one of the founders at Groupon, the client is poised to transform how utilities run and how customers experience energy.

System Modernization : Transform legacy workflows into modern, secure, scalable codebases using cloud-native best practices
Security & Compliance : Partner with security leaders to ensure all services adhere to stringent utility-sector regulations, implementing secure coding practices by default
Agile Delivery : Deliver features and improvements in cycles measured in weeks, balancing speed with reliability

Required Experience
Excellent English communication skills
5+ years of software engineering experience in SaaS or enterprise environments
Strong proficiency in React.js, Python, and either Golang, Node.js, or Java (non-Golang developers will learn and adopt Golang on the job)
Demonstrated ability to deliver high-quality code in fast-moving teams
Basic proficiency with AI/ML tooling (e.g., calling APIs, integrating model outputs)
Solid understanding of databases (SQL and NoSQL), message queues, and distributed architectures
Cloud-native engineering experience (AWS, Azure, GCP)
