Senior Backend Engineer

We are looking for a Senior Backend Engineer with 2-5 years of experience to help rebuild and scale Grid's cash advance platform from a scrappy prototype into a system capable of processing hundreds of millions in originations. You'll be a generalist who can take a business outcome and drive the technology end-to-end, working across distributed systems, financial infrastructure, data pipelines, and internal tooling.

What will you be doing?

- Rebuilding core backend systems (ledger, transaction processing, payment integrations) to support 5-10x growth in advance originations

- Building high-reliability, high-scale collection systems that make targeted transactions across thousands of small-cap advances daily

- Ingesting and processing massive volumes of customer banking data from partners to power underwriting and collection decisions

- Using SQL and data analytics to drive engineering decisions, monitor system performance, and validate business outcomes

- Designing and operating event-driven distributed systems with Pub/Sub and asynchronous workflows

Key Requirements

- Demonstrated ownership of solving a real problem with technology — you can point to a specific business outcome you drove, not just features you contributed to

- Startup or high-growth company experience (Series A/B preferred) — must be comfortable with ambiguity and operating without heavy direction

- Strong backend systems experience (distributed systems, data-heavy architectures) — at least half of your career should be backend-focused

- Data-driven mindset — able to write SQL, build analyses, and use metrics to guide decisions in a B2C fintech environment

- Must be on-site full-time in Seattle, WA
