Grid is a fast-growing team that’s deeply passionate about making a difference in the lives of millions. We’re solving huge problems and believe that every team member has a big role to play.

The role

We’re adding Backend Engineers to help build the foundations that power everything at Grid.

You’ll work across product, core financial systems, infrastructure, and data,  — working throughout the backend stack to power and improve our user experiences. From distributed systems processing millions of transactions to product facing components directly impacting the user experience, you’ll own critical components that scale with the company and directly impact how our products perform in the real world.

If you enjoy building high-leverage systems from scratch, this role puts you at the center of it all.

The team

We're focused on serving our users above all else all while building a robust business. To this end, Grid's team members experience high levels of autonomy and ownership, and as a company we value curiosity, learning and growth.

At Grid, you'll be surrounded by a team that is motivated, mission-driven and pragmatic.

The tech stack

Our backend platform runs on GCP with Go, protobufs, BigQuery, MySQL, and Spanner.

We’ve built a wide range of homegrown systems that power everything from financial ledgers and payment processing to AI-driven workflows, web scraping, and real-time analytics. From day one, we’ve focused on clean, reliable foundations — giving us a platform that scales efficiently and enables fast, data-informed product development.

• Shipping & Iteration: You’ll own systems end to end — from design and implementation through deployment and production support — using our rapid CI/CD pipeline to ship improvements daily. We take a data-driven, iterative approach to building toward ambitious goals through well-engineered, incremental releases.

• Data Analysis: Grid is deeply data-driven, with robust pipelines and analytics infrastructure across the platform. You’ll use SQL and analytical tools to evaluate product and system performance and help define what success looks like by shaping the metrics that guide our decisions.

• Event-Driven Distributed Systems: Grid’s backend is built around Pub/Sub and asynchronous workflows. You’ll design and operate distributed, event-driven systems; reasoning about state, consistency, and failure modes to deliver reliable, seamless user experiences at scale.
