Core Platform Engineer | On-site | Seattle

About us
Today’s financial system is built to favor those with money. Grid’s mission is to level that playing field by building financial products that help users better manage their financial future. The Grid app lets users access cash, build credit, spend money, optimize their taxes, and lots, lots more.

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 Core Platform Engineers to help build the foundations that power everything at Grid.
You’ll work across infrastructure, data, and core financial systems — partnering with product and engineering to design the platforms behind our user experiences. From distributed systems to cloud tooling, 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.

What you'll do :
• Systems Development: You’ll build the core systems behind Grid’s products. From transaction processing and financial ledgers to the infrastructure that powers everything we ship. Your work will sit at the foundation of the platform and directly shape how our products scale and perform.
• 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.
• Infrastructure & Architecture Ownership: You’ll actively shape Grid’s platform by diving deep into our infrastructure and core systems. You’ll evaluate tools, architectures, and design patterns, drive foundational improvements, and ship meaningful changes while thoughtfully managing reliability, risk, and scale.

Who you are:
• Backend Systems Experience: You have real experience building and operating production backend systems, ideally in Go on cloud infrastructure like GCP, and are comfortable owning services that must be reliable, scalable, and performant.
• Data-Driven Backend Systems: Proven experience building and operating backend systems that are deeply informed by data, designing clean data models, instrumenting services with meaningful metrics, and using analytics to guide system and product decisions.
• Cloud Experience: You’ve built production systems on major cloud platforms like GCP, AWS, or Azure, with real ownership over infrastructure and service reliability.
• Startup Person: You seek high growth opportunities and are constantly learning about the world around you. You feel at home with dynamic decision making and an iterative approach.
• Autonomy and Initiative: Ability to work independently and take ownership of projects, showcasing a proactive approach to identifying key leverage points for data products.
• Curiosity and Optimism: People who are constantly asking why the world around them work the way it does, and who have the will to change it.
• Self Starter: Confidence to prioritize work and delivery demonstrable results on a tight cadence.
• Domain Knowledge: Background in fintech, financial infrastructure, or security-focused systems is a strong plus, but not a requirement.
