Senior/Staff Back-end Engineer

About the role

Arbor helps renters, homeowners, and small businesses pay less for electricity. We are building an intelligent electricity marketplace to power an abundant electric future. We've raised over $20 million from leading investors and have saved over $7.5 million for tens of thousands of homes and businesses.

Responsibilities

• 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
• Create 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

Requirements

• 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

Qualifications

• 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
