The Role
As a Senior Back-end Engineer, you'll design scalable server-side services, manage cloud infrastructure, and collaborate on data integrations, all while leveraging AI and ensuring product ownership.
Summary Generated by Built In
We're looking for a backend-focused engineer to join our lean, high-leverage engineering team building the infrastructure that powers our energy marketplace. You'll work across our platform—from rate monitoring systems that track complex utility pricing across deregulated markets, to the marketplace orchestration that matches customers with optimal suppliers. This is a high-ownership role where you'll ship production systems, not just features, and where AI-augmented development practices are the norm.
What You'll Do
Design and build scalable backend services that power our core marketplace platform
Develop and maintain cloud infrastructure on GCP using Terraform, ensuring reliability and cost efficiency as we scale
Build integrations with utility data sources, supplier APIs, and third-party services across multiple energy markets
Create robust data pipelines for real-time rate monitoring and market intelligence
Partner with product and cross-functional partners to translate system and supplier needs into high-performing, resilient experiences. Take product ownership on select features and projects when necessary
Collaborate closely with a small team where your code ships fast (multiple daily prod deploys) and your architectural decisions matter
Leverage AI tools and workflows and uplevel the team around you
What You Bring
5+ years of backend engineering experience with production systems at scale
Strong JavaScript/TypeScript expertise: Node.js for backend services, familiarity with Nest.js a plus
Hands-on experience managing cloud environments including serverless and event driven systems built on native cloud tooling (GCP experience preferred)
Terraform proficiency for infrastructure-as-code; you've managed real cloud environments, not just tutorials
Comfort with databases (SQL, ideally Postgres), API design, and async processing patterns
AI fluency: you actively use AI coding tools and are eager to push the boundaries of AI-augmented development
Bias toward shipping; you thrive in environments with ambiguity and move fast without sacrificing quality
Interest in energy, climate tech, or marketplace products is a strong plus
