## Job description

## About Arbor

Arbor helps renters, homeowners, and small businesses pay less for electricity. Behind the scenes, Arbor 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 Opportunity

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

## Compensation & Work Setup

- Competitive salary + meaningful equity + benefits
- Remote-friendly with occasional in-person collaboration as needed

## About Arbor

## Company Overview
- **One-liner**: Arbor is a digital energy platform that automatically finds and secures lower electricity supply rates for homeowners and renters in deregulated energy states, saving them money on their utility bills.
- **Entity Type**: Private (Seed Stage)
- **Headquarters**: Austin, Texas, United States
- **Founded**: 2023
- **Founders**: Not publicly listed on the website or LinkedIn

## Core Business
- **Primary industry/industries**: Utilities, Energy, Climate Tech
- **Target customers**: B2C (homeowners and renters in deregulated energy states across the US)
- **Mission or purpose statement**: "We built Arbor so you don't need to spend brain power thinking about your power." The company is "united by our belief in a better energy world - one that gives everyday people access to abundant, affordable and renewable electricity." [joinarbor.com](https://www.joinarbor.com/about)

## Products & Services
- **Arbor App**: A free, consumer-facing platform that connects to a user's utility account, analyzes their current electricity supply rate, and automatically switches them to a lower, fixed-rate plan from a vetted supplier. The service is available to renters and homeowners in 13 deregulated energy states. The app also recommends relevant home electrification upgrades. [joinarbor.com](https://www.joinarbor.com/)

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metric**: Total Funding of **$9.0M** (Seed Round). The company has saved customers over **$30M** in power bill savings. [linkedin.com](https://www.linkedin.com/company/joinarbor)
- **Notable Investors/Partners**: First Round Capital (led Seed Round), Blisce (led Series A). [linkedin.com](https://www.linkedin.com/company/joinarbor)
- **Growth Signals**: The company is available to eligible renters and homeowners across 13 states. It has saved customers over $30M and has a 4.6/5 star Trustpilot score. The company has 8 active job postings, with a 700% yearly increase in job postings. [linkedin.com](https://www.linkedin.com/company/joinarbor)

## Competitive Advantages
- **Automated Savings**: Arbor's core differentiator is its fully automated process. Users sign up in two minutes, and the platform continuously monitors the market to automatically switch them to the best available fixed-rate plan, eliminating the need for manual research and preventing "promo rate" expirations.
- **Zero-Cost to Consumer**: The service is completely free for users. Arbor makes money via referral fees from energy suppliers, creating a business model that aligns with the customer's best interest (lower rates).
- **Seamless Experience**: The switch does not require new equipment, installation, or service interruptions. The user's utility company remains the same, and they continue to pay a single bill.
- **Risk Mitigation**: Arbor offers a guarantee to reimburse any early termination fees incurred if a user moves, removing a major barrier to switching.

## Strategic Focus
- **Geographic Expansion**: Arbor is currently available in 13 deregulated states (NE, Midwest, and Texas). A key strategic focus is likely expanding into additional deregulated markets.
- **Product Expansion**: Beyond rate switching, Arbor is building a platform to recommend "the most relevant home electrification upgrades" (e.g., solar, heat pumps, EV chargers) and help customers "live more sustainably." [climatetechlist.com](https://www.climatetechlist.com/company/arbor)
- **Automation & AI**: The company is heavily focused on building technology to automate the complex energy market, using a "robo" approach to monitor rates and switch customers automatically.

## Why Work Here
- **Mission-Driven**: The team is united by a belief in "a better energy world" and making affordable, renewable electricity accessible to everyone. [joinarbor.com](https://www.joinarbor.com/about)
- **High Impact, Small Team**: With only 26 employees, new hires will have significant ownership and direct impact on the product and millions in customer savings.
- **Strong Growth Trajectory**: The company has saved customers over $30M and is actively hiring, with a 700% yearly increase in job postings, indicating a period of rapid scaling. [linkedin.com](https://www.linkedin.com/company/joinarbor)
- **Engineering Culture**: The current open roles are heavily focused on engineering (Data Engineer, Senior/Staff Back-end Engineer), suggesting a strong, technical core. [jobs.ashbyhq.com](https://jobs.ashbyhq.com/arbor)
- **Location**: Based in Austin, TX. The company's remote/hybrid policy is not explicitly stated, but the headquarters is in Austin.
