Full Stack Software Developer (work anywhere in LATAM)

Our Mission

Loopfour is building workflow automation for finance operations.

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.

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.

This is a chance to build early, build deeply, and grow alongside a small team that cares about doing things the right way.

If you want to look back one day and say, “I helped build that from the ground up,” this is that role.

What we value

• Strong fundamentals and genuine curiosity
• Ownership mindset and high agency
• Comfort with ambiguity and fast iteration
• Clear communication and respect for users

You'll start with a Zoom conversation with the founders and team to see if there's a fit. If there's mutual interest, we'll ask you to show us something you're genuinely excited about: a side project, a prototype, a tool you've built and love, or a walkthrough of your GitHub.
