About ArborArbor is building an intelligent electricity marketplace to power an abundant electric future. As AI data centers drive a surge in electricity demand, millions of homes and businesses remain trapped with 20th century monopoly interfaces, overpaying by billions while cheap renewable energy goes to waste. Our AI-powered platform aggregates users to unlock wholesale pricing, automatically switches between the best rates, and optimizes usage to align with prices in real-time-delivering the same market advantages that were previously exclusive to Fortune 500 companies. We've raised over $20 million from leading investors and have saved over $7.5 million for tens of thousands of homes and businesses.
The OpportunityWe'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
Compensation & Work Setup- Competitive salary + meaningful equity + benefits
- Remote-friendly with occasional in-person collaboration as needed
