Staff Software Engineer, Affirm Bank

Responsibilities

• Set technical direction across the bank's systems.
• Own the medium-to-long-term technical strategy for the bank's core surfaces — cloud infrastructure, data platform, core banking configuration, CI/CD, networking, and the Bank ↔ Affirm Inc integration — and make the architecture calls the rest of the team builds against. Generalist breadth is expected; you go deep where…
• Own the hardest problems end-to-end. Personally design, build, integrate, and operate the most ambiguous and highest-stakes pieces of the stack, and own incident response for them. You take the problems no one else can fully scope and turn them into well-defined systems with clear failure domains, monitoring, and…
• Be the force multiplier on a small team.
• Set and hold the bar for code review, design review, and examiner-readable documentation. Establish the patterns and standards that let a deliberately small team punch far above its size, and level up every engineer who joins after you.
• Ship AI-first, and push the frontier of it. Treat AI tools and agentic workflows as a load-bearing capability for code, design review, runbook generation, and operations — and actively push yourself and the team on what an AI-leveraged engineering function can deliver in place of additional headcount.
• Lead vendor selection and ownership.
• Drive evaluation, integration, and ongoing oversight of the bank's third-party platforms across the core, data, identity, observability, and card-processing stacks. Carry the bank's most critical vendor relationships end-to-end: integration, operations, escalation, and audit.
• Define the integration boundary with Affirm Inc.
• Set the domain edges, data flows, and integration patterns between the bank and Affirm Inc so the bank's products work seamlessly inside the Affirm ecosystem while preserving the legal and regulatory separation the charter requires.
