Our software takes the manual, repetitive work off finance teams so they can focus on the decisions that matter. Finance teams spend their days moving documents between tools, chasing approvals, and reconciling numbers that already exist somewhere. We are building automation that fits how a business actually operates, in the tools teams already use, with a full audit trail behind every action. AI for finance, without the black box. 👉 Apply directly at https://loopfour.ai/careers (we review direct applicants first) You'll work across our TypeScript stack: the workflow builder, the durable runtime that executes those workflows, and the integrations that connect them to the tools finance teams already use. This role is for someone who loves to learn, loves to build, and cares deeply about craft. Someone who can think through hard problems, write clean code, and isn’t afraid to make decisions. Titles matter less than impact here. This is a high-agency role. You architect solutions, ship features to production, and shape product direction directly. Expect to touch real systems that move real money and to feel the impact of what you build. We want someone who enjoys hard problems, moves fast without breaking trust, and cares about the people on the other side of the screen. What you’ll do Design, build, and maintain scalable features across the workflow builder, API, and durable runtime Build and integrate APIs for financial data processing and automation Collaborate with cross-functional teams to implement new features and improvements Work with AI/ML models to enhance automation capabilities Turn messy real-world finance processes into clean, reliable automated workflows Own performance, correctness, and observability of the systems you ship Write clean, maintainable, well-tested code and participate in code reviews Debug and resolve complex technical issues across the full stack What we’re looking for S3+ years building and shipping full-stack web applications Proficiency in TypeScript, React, and Node.js Experience with databases (PostgreSQL, MongoDB) and cloud platforms (AWS, GCP) Knowledge of RESTful APIs, GraphQL, and microservices architecture Familiarity with containerization (Docker) and CI/CD pipelines Experience with AI/ML integration and data processing preferred Fintech or financial systems experience is a plus Bachelor's degree in Computer Science or equivalent experienceYou don’t need to check every box. If you’re smart, driven, and excited about building something important, we want to hear from you.
