About Hearth

Hearth is the AI growth system for America's home improvement contractors. With 15,000+ paying customers, default profitability, and backing from top-tier investors like Founders Fund and 8VC, we provide the revenue-critical software tradespeople rely on to run their businesses.

We are now building our next layer of innovation: an autonomous AI employee for every contractor. By answering calls 24/7, qualifying leads, and booking jobs, this AI ensures small businesses never miss a lead again. We're on a mission to bring AI to the trades—and we need your help to build it.

The Opportunity

We are searching for a strong backend engineer to join a small, high-ownership team at a pivotal moment. Our backend is actively migrating from a Ruby on Rails monolith to a Go microservice architecture that will power our AI features, payment flows, and third-party integrations at scale.

The role works directly with the CTO on the distributed systems and orchestration infrastructure powering long-running AI workflows across voice, messaging and financial products. The team is 8 people and prioritises velocity, ownership and shipping over process.

What You’ll Do

• Build and maintain APIs that serve 15,000+ active contractors payments, onboarding, lead management, and AI-powered workflows
• Integrate with third-party services payment processors, CRMs, communication platforms (Twilio), and other contractor-facing tools; ensuring those integrations reliable and observable
• Contribute to the Rails → Go migration: move data models and business logic into Onikisu to expand the context available to our AI products
• Design data models that don’t become technical debt six months later
• Debug production issues independently. Find the root cause, fix it, and make sure it doesn’t come back
• Review code as someone who holds a high bar and helps teammates level up

What We’re Looking For

• Go or strong polyglot depth. Go is preferred; ideally you’ve shipped and maintained Go services in production. Strong engineers from another language who are excited about Go are welcome. 
• API and integration experience. You’ve built production integrations with payment processors (Stripe, Braintree), CRMs, and communication platforms (Twilio, SendGrid) and know how to keep them reliable and debuggable.
• Payments mindset. Correctness over cleverness. A bug in financial software isn’t bad UX it’s money moving the wrong way. Independent debugging. When something breaks, you dig in and don’t call it done until you know why it happened. 
• Startup background. You’ve worked somewhere that ships fast, ideally zero to one or through a scale event. You make decisions without perfect information and don’t wait to be told what to do. 
• Bonus. Rails codebase experience (useful migration context) or familiarity with RAG pipelines and LLM-adjacent data architecture.

What We’re Not Looking For

• Someone who needs a well-defined ticket before starting work
• Someone who treats code review as a formality
• Someone who escalates bugs to QA rather than debugging them independently
• Someone whose primary experience is cloud infrastructure or DevOps — we need product engineers who own features end to end
• Someone who measures success by tickets closed rather than systems that work
• Someone looking for a large company with narrow ownership and a long approval chain

Benefits

• Mission-driven, values-based culture
• Competitive pay
• Unmatched opportunities to learn and develop; front-row seat at a fast-growing tech startup
• Generous PTO, plus paid company holidays
• Stock options
• Medical, dental, and vision options
• 401(k)
• Free Employee Assistance Program
• Parental Leave Program
• Pet Insurance

The Opportunity

At Hearth we are committed to making a meaningful impact on home improvement professionals across America and every PR you merge will be in furtherance of this goal. We are driven by our customers and the features you ship will have immediate meaningful impact. This role is for strong engineers that want more than just to write “good” code but also are looking to help create something with real impact. At Hearth customer feedback is taken seriously and acted on, we are obsessed with building the best possible version of our software. 

You will be part of a small tactical team where delivery is key and will have responsibility over  a wide range of products and technologies. You will be expected to not only deliver quality code and a quality customer experience but also to work closely with the product and customer success teams to help shape our future. 

This role is for someone who loves building, learning and growing.

• Design and deliver complex technical solutions that leverage the latest technologies (yes AI) to deliver a world class customer experience.
• Build APIs and services that enable a new form of entrepreneurship empowerment for over 3 million small business owners
• Build and integrate with financial service technologies for payments, banking, and loans
• Support the technical infrastructure that powers over 14,000 small businesses.
• Collaborate with product, design, and across engineering on the strategic vision for our product roadmap
• Contribute to a culture of technical excellence through code and design reviews
• Deliver high-quality, secure, and testable code
• Mentor other engineers and contribute to the engineering culture

What We’re Looking For:

• 3+ years of technical experience building and maintaining core backend systems
• Experience deploying to and monitoring your systems on AWS 
• You have owned and lead projects from planning phase through delivery and support
• You think about performance and trade offs constantly 
• Experience working with data pipelines and you are comfortable connecting systems you build to existing data infrastructure
• You have working with financial service APIs such as payments processors or lender origination 
• Experience as a generalist, working on whatever part of the stack necessary to solve the problem at hand
• A passion for building delightful applications and the systems that support them
• Care deeply about the quality of your work while balancing delivery expectations.
• An obsessive focus on customers and iterative learning.

Our Core Values

• Truth. We value honesty and data. We seek to understand what is reality, so we can effectively respond to it.
• Slope. Rate of change over time. We hire and reward based on a team member’s potential, capacity, and growth-mindset, rather than a fancy resume. 
• Mutual Benefit. The best outcomes happen when everyone wins - customers, team members, and the company. We seek to understand each other’s aspirations and create alignment to get there.
•  Competitive Greatness. We desire an opportunity and environment from which to pull the greatest versions of ourselves out into the world, rather than just a “job”.
