Senior Full-Stack Software Engineer / Technical Lead
Job Description
About Green
Green is building a global consumer neobank. We're merging banking, payments, and crypto into a single product. Our initial focus is emerging markets, where traditional banking and local currencies fail hundreds of millions of people. We will enable users all over the world to move their money seamlessly within our ecosystem.
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
