Their platform helps investment teams at organizations like universities, hospitals, retirement systems, and wealth managers replace highly manual reporting, analysis, and reconciliation workflows with AI-powered automation. This is an opportunity to join a small, highly technical team where engineers have significant ownership and work directly with the customers using what they build. You'll work across the entire product—from systems that understand hundreds of thousands of financial documents to AI agents capable of turning a client's request into a finished report. The company has approximately $1M in ARR with zero customer churn and is building a product that is already delivering significant efficiency gains for its customers. What You'll Do Own features and products end-to-end across backend, frontend, infrastructure, and AIBuild and improve AI agents that perform complex analysis and knowledge workDevelop systems that process and understand large volumes of financial documents and institutional dataWork directly with customers to understand problems and rapidly turn them into production solutionsMake key technical and product decisions in a highly autonomous engineering environmentUse AI extensively throughout the development process to move from idea to production quicklyTake responsibility for the quality and performance of what you ship What We're Looking For 5–10 years of full-stack software engineering experienceExperience owning and shipping production software end-to-endStrong technical judgment and problem-solving abilityHigh level of ownership, initiative, and personal accountabilityComfortable working through ambiguous problems without a detailed roadmapAbility to move quickly while maintaining high standardsInterest in working closely with customers and seeing your work used in productionExcited about AI-native software development and using AI as a core part of the engineering process Tech Stack: Python, React, TypeScript, AWS, PostgreSQL, MongoDB A specific technology background or previous finance experience is not required. The team prioritizes raw technical ability, judgment, work ethic, and ownership over checking every box on a traditional tech-stack list. Why You'll Love This Opportunity You'll join a small engineering team where your work can have an immediate impact. There are no layers of product managers, QA teams, or engineering management handing you narrowly defined tasks—you'll have the autonomy to identify problems, determine the right solution, build it, and ship it. The team is also operating at the forefront of AI-native software development. AI generates much of the code, allowing engineers to focus more heavily on architecture, product decisions, agent behavior, and the judgment required to build reliable systems. You'll work alongside people with backgrounds in quantitative finance, high-performing engineering organizations, and previous startups, including companies that were acquired by Nasdaq and ADP.
