About the Role Our client is an early-stage, venture-backed fintech startup on a mission to expand access to financial tools for people historically excluded from the traditional credit system. They're growing fast, capital-efficient, and looking for a Backend Engineer to help build and scale the infrastructure powering their products. This is a high-ownership role for someone who wants to own systems end-to-end, move fast, and lean heavily into AI-assisted development to multiply their output without sacrificing quality. What You'll Do * Own backend systems and infrastructure end-to-end, from design through deployment and scaling * Build performant, reliable APIs and services that power core financial products * Design and implement scalable architectures on AWS using Node (TypeScript) * Make pragmatic tradeoffs between speed, reliability, scalability, and maintainability * Ship production code frequently while maintaining high quality standards * Help establish technical patterns and best practices for the engineering team * Interface effectively with product engineers and other stakeholders What We're Looking For * Bachelor's degree in Computer Science or a related technical field * 5+ years of professional software engineering experience, with a significant backend focus * Experience building and scaling production systems with Node and AWS * Proficiency with TypeScript strongly preferred * Track record of delivering reliable, performant systems at scale * Systems-oriented mindset with a deep focus on performance, reliability, and scalability * Strong sense of ownership and accountability for system outcomes * Comfortable thinking critically about architectural decisions and their long-term implications * Thrives in ambiguity and can make sound technical decisions with incomplete information * Self-starter who can work independently and drive projects to completion * Embraces AI-assisted development to accelerate output while maintaining high code quality What to Expect * High ownership with minimal bureaucracy * A fast-moving environment where roles and priorities evolve quickly * An intense pace of execution and growth — this is not a 9-to-5, work-life-balance-optimized role * Speed, learning, and impact as core values Compensation Salary range of 150-250k USD/year + equity, depending on location and seniority.
