Software Engineer, Full Stack San Francisco, CA | New York City, NY | Remote

Our mission is to make it simple to headquarter any business on the internet. Today, we provide companies with a business address and a dashboard to manage their physical mail online. Over 10,000+ companies like Gitlab, Glassdoor, and Indiegogo use Stable to automate their mailroom and act as their permanent business address with the IRS, state, and vendors.

The rules that regulate US entities were written in the 1800s. Stable abstracts these antiquated requirements with tools that empower modern companies to move forward faster.

These rules don't make sense for the way we work today — work takes place in the cloud and businesses are no longer tied to physical proximity or geography.

We’re on a mission to fix the broken system of entity management. Starting with business addresses and mail, we’re abstracting the complex, archaic systems that make company-building painful and turning them into delightful experiences — so that modern businesses have the tools they need to move forward faster.

We're backed by leading Silicon Valley investors like Y Combinator, Craft Ventures, Shakti, Hustle Fund, and founders from companies like Lattice, Apartment List, and FlexJobs.

Our business is at an inflection point. We’re growing quickly with a product people love and we’ve proven we can service companies of all stages and industries — from early-stage startups to publicly traded companies in industries like technology, logistics, and property management.

This is an opportunity to join an early-stage startup as one of the first employees and do work that directly impacts the future of how companies are built.

We’re looking for a full stack engineer with 4+ years of experience to join our small team and help us build the software backbone of modern business infrastructure.

Supporting over 10,000 businesses with a lean team means we focus on impact. Engineers talk to users, identify real-world bottlenecks, and ship code that unlocks speed and scale. There’s no one handing you tickets — you’ll define what matters, then build it.

You’ll work across the stack — frontend, backend, and occasionally hardware — to build software that abstracts away outdated and painful business operations. You’ll have a direct hand in shaping the core systems that power our product and logistics.

Some examples of what you might work on :

• Stable Dashboard — The main interface our customers use to triage mail and take action. From forwarding documents to triggering internal workflows, it’s a daily tool for founders, ops teams, and finance leaders.
• Mail Operations Tools — Internal software that powers how we intake, route, and fulfill physical mail requests. You’ll write code that integrates directly with scanners, label printers, and other hardware to help our ops team move faster and with fewer errors.
• Automation & AI — Use LLMs and rule-based systems to process incoming mail, extract relevant information, and automate next steps — from routing to support to operations.
• Stable API & Webhooks — Design and maintain a reliable, well-documented API and webhook system that external teams use to integrate with Stable. Supports high-volume use cases in fintech, healthcare, logistics, and more.

This role is for someone who enjoys building practical products that solve real problems. You’re comfortable with ambiguity, ask questions, and ship code with clear, measurable impact. You thrive in a collaborative team and value open communication and joint problem-solving.
