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.
