Product Engineer

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 product engineer with 3+ years of experience to join our small team and help us build the software backbone of modern business infrastructure.

Supporting 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 play a role in both defining what matters and building it.

You’ll work across the full stack—frontend, backend, and occasionally hardware. The problems are tangible and the feedback is fast: you might train the AI model that detects a check inside a document, then write the integration that extracts the data to deposit it, then watch it run in a real warehouse the same week. 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 - Our customers’ central hub for business operations. They login to automate their mail, manage registered agents, reconcile payments, and set up workflows that help their team move faster.

• Mail Operations - Hardware integrations and internal software that powers how we intake, route, and fulfill customer requests.

• Automation & AI - LLMs and ML models that route mail, classify documents, extract data, and trigger workflows.

• 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, excited to talk to customers, and ship code with clear, measurable impact.

• Be human: Lead with empathy, act with authenticity, and enjoy what you do.

• Stay curious: Invent novel solutions by asking why, listening, and tinkering.

• Act quickly with purpose: Focus on what matters, iteratively improve, and move urgently towards the goal.

• Insist on exceptional outcomes: Strive for excellence and take ownership over the outcomes you deliver.

• Exceed customer expectations: Create delightful experiences with each interaction.

• Obsess over the customer to build pragmatic solutions to their problems

• Lead end-to-end implementation of features, from discovery through implementation

• Design software that solves real-world logistics challenges—often involving both automation and human-in-the-loop workflows

• Architect and implement core infrastructure that helps us scale both customer and mail volume

• Balance technical complexity with input from customers, operations, and the business

• Technologies we use: React, Typescript, Node, GraphQL, MySQL, and AWS (if you think a new technology can solve an engineering problem, we’re all ears)

• 3+ years of experience as a product engineer, full stack engineer, or similar

• Evidence of customer empathy and business context—you understand who you build for, why, and what impact it drove

• Self-directed and comfortable leading projects end-to-end with loosely defined scope

• Strong communication skills—you can explain technical concepts to non-engineers

• Comfortable with ambiguity and a fast-paced, high-growth environment

• Travel at least quarterly for company offsites

• Nice to have: Experience in startup environments or early-stage product work.

• Nice to have: Familiarity with warehouse or fulfillment center technology.

• Competitive salary and generous equity 🚀

• Unlimited paid vacation 🏖

• Medical, dental, and vision insurance 🏥

• Home office set-up 🖥

• Work from anywhere within US time zones (GMT-5 to GMT-10) 💻

• Opportunities to shape the future of Stable and grow into leadership roles 💌
