We're looking for a Backend Developer who thrives in high-scale, high-impact environments. This is not a purely internal role; you'll be in the loop when critical issues arise, often working with our support and customer-facing teams to debug real-world problems for customers. You'll be building infrastructure that processes millions of requests per day while ensuring clean, maintainable, and testable code. You'll collaborate asynchronously across engineering, support, and design, all in a remote-first, fast-moving startup environment. This role is ideal for someone with deep backend expertise, strong systems thinking, and excellent communication skills to clearly explain technical concepts to internal stakeholders and occasionally support high-impact customer debugging. Responsibilities: Analyze and improve backend infrastructure to support performance, scalability, and reliability at scale. Design, build, and maintain APIs and backend logic using Node.js, Postgres, MongoDB, and AWS services (Lambda, EC2 ECS, Fargate, Docker). Collaborate with support to resolve customer-reported issues and debug production-level bugs with clarity and urgency. Review, maintain, and refactor legacy codebases with a focus on testability, performance, and long-term maintainability. Submit and review Pull Requests, give feedback, and uphold code quality across the team. Collaborate with frontend developers to define API contracts and data protocols for smooth client-server interactions. Work with designers and product managers to scope features, translate user needs, and deliver backend support for real business outcomes. Document processes, share knowledge asynchronously, and contribute to an engineering culture of clarity, trust, and high standards. Requirements: You have 7-8 years of backend development experience in high-scale environments. You've previously owned systems handling 5M requests per day. You're fluent in Node.js, JavaScript, PostgreSQL, MongoDB, and the AWS stack (EC2 ECS, Lambda, Fargate, Docker). You're highly confident in designing RESTful APIs, working with async systems, and optimizing DB performance. You have 2-3 years of GraphQL experience and understand how to structure scalable schemas and resolvers. You're an excellent written and verbal communicator, clear, thoughtful, and customer-aware. You can work independently in a remote async setup but collaborate seamlessly with support, product, and engineering teams. You're comfortable working USA hours and engaging with teams or customers in North America. You have experience working in fast-paced startups with a bias for speed, iteration, and ownership. You care about design and usability, not just systems; you want the backend to support great user experiences. (Bonus) You have frontend experience, especially in Vue.js or modern JavaScript frameworks, and can jump in if needed. J-18808-Ljbffr
