• Take full ownership of core services and feature delivery—from initial architecture and technical design through to deployment and production monitoring.
• Translate product requirements into functional, maintainable, and extensible software while identifying technical requirements in product planning meetings.
• Write automated developer tests for new features and update existing test suites to maintain low response times, high signal-to-noise quality, and optimal application performance.
• Partner with QA and engineering colleagues to develop comprehensive test strategies, perform root-cause troubleshooting, and resolve complex application issues.
• Participate in a regular team on-call rotation to maintain platform reliability and high availability for global merchants.
• Responsibilities listed are not intended to be all-inclusive and may be modified as necessary.

• Education: Bachelor’s Degree in Computer Science, Engineering, or a related technical field (or equivalent practical experience).
• Software Delivery: 7+ years of professional experience designing, developing, delivering, and supporting critical enterprise web applications.
• Frontend Mastery: Strong proficiency with JavaScript, TypeScript, HTML5, CSS, SASS/LESS, browser DOM APIs, and web build systems (e.g., Webpack, Gulp, Grunt).
• Modern Frameworks: Deep experience building responsive, highly accessible web applications using React, Next.js, or Ember.
• API & Data Engineering: Solid hands-on experience developing REST and GraphQL APIs, along with working knowledge of relational (MySQL) and NoSQL (MongoDB) databases and complex query design.
• Cloud & Automation: Experience working in cloud environments (preferably GCP) and writing automated web tests using modern frameworks (Jest, Cypress, Selenium).
• Modern Architectures & Tools: Proven experience in Agile environments using Git, with an understanding of modern web architectures (micro-frontends, Webpack Module Federation, service workers).

Experience that would be great to have

• Communication & Collaboration: Excellent written, verbal, and interpersonal communication skills, with a track record of effective cross-functional teamwork.
• AI-Assisted Development: Proven experience leveraging AI software engineering tools (e.g., GitHub Copilot, IDE plugins, AI coding agents) to optimize workflows, accelerate debugging, and elevate overall developer velocity.
• Back-End development or light knowledge in Java, Spring Boot & Microservices.
