Job summary

Expensify, Inc. is seeking a Full Stack Engineer for a US-based remote role within our Engineering team. You will build cross-stack features, collaborate with designers, customers, and external contributors, and drive impactful product decisions in a fast-paced environment.

You will work across product, code, and AI to ship reliable features, improve performance, and ensure exceptional user experiences. We value self-direction, clear communication, and a growth mindset in a remote-first setting.

Qualifications

• Strong command of design patterns and system design, applied in production-level code.
• Clear communication, written and spoken, including native-level English.
• A natural problem solver who automates solutions instead of repeating work.
• An understanding of the role and impact programming has on the organization as a whole.
• A drive to grow your skills in programming and leadership within the organization.
• Experience with JavaScript, React, React Native, PHP, C++, Java, iOS, or Android.
• (Bonus) Experience in maintaining a codebase that takes outside contributions, such as an open source project

Responsibilities

• Plan, build, and maintain cross-stack features like accounting integrations, advanced receipt scanning, calendar integrations, and credit card transaction imports
• Squash bugs and improve the reliability of our app, so the things we ship keep working
• Maintain and improve high-quality code to give customers industry-leading experiences
• Review pull requests from internal engineers and external contributors, guiding both quality and direction
• Use AI tools across your workflow to increase efficiency, with good judgment about when to trust the output and when to dig in
• Make product calls on what to build, what to cut, and what to rethink, with clear reasoning for each
• Spot repetitive work and automate it, so no one does by hand what a script can do
• Share what you know: we’ll share our editor tricks, dotfiles, and productive workflows, and we want yours too
• Lift up the team around you to do more with less, work smarter, and pitch in to keep the lights on.
