Senior Full-Stack Software Engineer / Technical Lead

About Green

Green is building a global consumer neobank. We're merging international banking and payments into a single product. Our mission is to enable all of our customers around the world to spend, save and earn in USD. We'll be starting the US and select international markets with ambitions to scale far beyond.

Green is built by a small group of highly experienced operators and engineers. We're a small, senior-only team, with no layers, politics, or slow decisions. We've built, founded, and owned services used by hundreds of millions of people and generating billions in revenue. Green is the next step and mass distribution is readily available via our day-one partners. Every person on the team ships product and shapes the direction of the company.

The Role

A Technical Lead on our team is a hands-on leadership role for candidates with breadth across multiple layers of our stack and the judgment to drive technical outcomes. We are building:

• An iOS app (Swift)
• An Android app (Kotlin)
• A Web app (React)
• A standalone backend (Python + FastAPI, Postgres, AWS)

If you bring a mix of these skill sets and can guide others to deliver high-quality software, this role may be a strong fit. Please also review our Senior Android/iOS/Frontend/Backend roles for deeper, discipline-specific details.

As an early engineering leader, you will define our architecture, set engineering standards, and lead the delivery of a performant, reliable, and secure product from the ground up. The problem space includes financial services with real-money movement at international scale and non-trivial compliance, integrity, and latency constraints. You will collaborate across product, design, and operations, and help grow and mentor the team. You will work directly with the founders. This role may expand to broader engineering leadership across platforms as we scale.

Requirements

• 7-10 years building and shipping consumer-facing mobile and/or web applications with meaningful full‑stack exposure (e.g., React/TypeScript, Python, Go/Rust, Postgres, AWS, modern CI/CD).
• Demonstrated experience managing technical teams, making architectural decisions, and mentoring engineers.

Bonuses

You might be an especially good fit if you have:

• Experience building for the Latin American market
• Experience in financial technology
• Strong systems-thinking and design sense

What We Offer

• $200K-$400K cash compensation
• Day 1 impact on partner products used by millions globally
  
• Shape technical vision and architecture as we scale
  
• Own major parts of the product and infrastructure
• Ship fast and avoid corporate overhead
