Full Stack Engineer

About the Role

We're looking for a motivated and skilled Full Stack Engineer (Software Engineer II) to join our growing engineering team. In this mid-level role, you'll play a critical part in designing, building, and maintaining features that power Roo’s veterinary marketplace. You’ll work cross-functionally with product, design, data, and engineering peers to bring scalable, high-impact solutions to life.

This is an excellent opportunity for someone who’s already gained a solid foundation in full-stack development and is ready to take on more responsibility - whether it’s owning features end-to-end, mentoring junior engineers, or driving architectural improvements.

We're in the builder era. Prompt-to-feature workflows are real, AI coding tools are the new norm, and the teams that win will be the ones who set up the right infrastructure to move fast with them. We're looking for an engineer who proactively embodies this builder mindset.

This is a remote-first role, with occasional travel to San Francisco for cross-functional events or team offsites as needed.

• Participate in technical design discussions and make meaningful contributions to architectural decisions.
• Lead by example through high-quality code, peer code reviews, and mentoring early-career engineers.
• Own the testing lifecycle for your features—writing unit tests with Jest and end-to-end tests with Cypress.
• Investigate and resolve production issues, improve observability, and contribute to platform reliability.
• Partner with DevOps and infrastructure teams to ensure smooth deployments, CI/CD workflows, and system performance.
• Stay up-to-date on industry trends and best practices, and proactively introduce improvements to tools, processes, or technologies.

Qualifications

• 2–4 years of professional experience as a Software Engineer, with strong proficiency in TypeScript/JavaScript
• Mobile development experience (e.g., React Native or another mobile framework)
• Experience with Node, Express, React, AWS, and relational databases
• Proficient at writing complex and efficient SQL queries
• Experience working with a growing team and early stage startup strongly preferred
