As our next Software Engineer, you'll help drive our growth in engineering platforms by building, shipping, and delivering results from day one. You'll work closely with engineers, operators and partners to turn frictionless payments into real growth for restaurants. You will also use AI-assisted development practices throughout the software development lifecycle and contribute to AI-powered and agentic systems that can reason, retrieve information, use tools, and execute controlled workflows. If you thrive in a fast-moving, build-from-scratch environment, this role is for you. What You'll Own * Design, build, and operate secure, scalable, and highly reliable payment services, including payment gateways, transaction processing, reconciliation, and settlement flows * Build and maintain integrations with POS systems, payment providers, financial partners, and other third-party platforms * Use AI-assisted development tools for discovery, implementation, debugging, testing, code review, documentation, and refactoring while maintaining strong engineering quality standards * Design and develop AI-powered and agentic workflows that can retrieve data, call tools, interact with internal systems, and execute controlled actions * Implement appropriate permissions, human approvals, guardrails, observability, auditability, and fallback mechanisms for agentic systems * Identify performance bottlenecks and improve the speed, reliability, security, and cost efficiency of payment and AI-powered workflows * Write clean, maintainable, tested, and well-documented code that follows software engineering and financial-system security best practices with AI * Contribute to technical design discussions, architecture decisions, engineering standards, and continuous improvement across the team Who You Are * You've done this before in a fast-moving, high-growth environment * You move fast and make strong decisions with incomplete information * You take real ownership and think like an operator, not a coordinator * You're energized by hard problems in payments, hospitality, and customer experience * You use AI development tools pragmatically to improve speed and quality without compromising security, maintainability, or engineering judgement * You collaborate effectively with engineers, product teams, operations teams, and external technical partners, * Real ownership over products that impact millions of diners and thousands of restaurants globally * The opportunity to solve challenging problems in payments, hospitality, and customer experience * A fast-moving environment where great ideas quickly become reality * Close collaboration with experienced operators, builders, and industry experts * A chance to leave a visible mark on one of the fastest-growing restaurant technology companies globally
