Senior Software Engineer, Full-Stack (Agents)

Role Description

Owner is the leading all-in-one platform for independent restaurants. Operators use Owner to run their online ordering, websites, menus, marketing, and customer experience. Tens of thousands of restaurants depend on us every day to run their business.

AI Agents at Owner is a team with a singular mandate: build agents that let restaurant owners run their business through natural conversation, everywhere they work with Owner. This is one of the most important strategic bets at Owner, and the team is early enough that you will shape the architecture, platform, and products from the ground up.

This role is 100% remote and can be based anywhere in the United States or Canada.

Qualifications

• 5+ years of software engineering experience, with meaningful time shipping production LLM-powered or agentic features.
• Fluency with tool calling, prompt engineering, and agent loops — you have built systems where the LLM is a first-class component, not a bolt-on.
• Experience with eval frameworks and observability for non-deterministic systems (Braintrust, LangSmith, custom eval harnesses, or equivalent).
• Full-stack comfort — you can move between backend orchestration, tool design, and conversational UI without being blocked by hand-offs.
• High degree of cross-functional collaboration — past colleagues in product, design, and business would speak highly of your teamwork.
• Strong sense of ownership and drive, excellent communication, and a proactive approach to identifying and solving problems.

Requirements

• Own one or more agent surfaces end-to-end, from LLM integration and tool design to backend orchestration, conversational UI, and evals.
• Contribute to the shared agent platform: tool abstractions, chat persistence, eval frameworks, RAG, observability, permissioning.
• Shape technical direction on agent architecture, framework choice, and model strategy across Owner.
• Make thoughtful tradeoffs on latency, cost, and reliability so our agents feel fast and trustworthy in production.
• Raise the bar for agent quality through rigorous evals, thoughtful iteration, and patterns other engineers adopt.

Benefits

• The estimated starting base salary range for this role is $210K-230K depending on level, location and experience, plus a generous pre-IPO equity package.
• Other benefits include comprehensive health coverage, work from anywhere (remote-first workplace), unlimited PTO - plus extra fun perks!

Company Description

Owner is the AI-native system local business owners use to succeed, starting with restaurants. We’re building the system that replaces the many tools owners use to run their business. It powers everything from the restaurant’s website, online ordering, CRM, POS, and more.

Since 2020, we've generated tens of millions in revenue and processed over half a billion dollars of online orders. 1 in 5 Americans have used an Owner.com website. More importantly, we’ve helped over 20,000 restaurant owners, and saved them nearly $200 million in fees.

Our team is now in the low hundreds. We’ve got top talent from the most successful companies in SMB software, including: Shopify, HubSpot, DoorDash, ServiceTitan, Rappi, Faire and Stripe. We’ll be scaling even faster in 2026 to keep pace with our customer growth.

Owner is a remote-first, global company headquartered in San Francisco, with a sales hub in Toronto. For a few of our roles we prioritize in-person collaboration at one of our office locations. Most of our teammates are distributed throughout the globe.
