Pay Grade - L Equity Grade - 6 ## Description At Affirm, data powers our underwriting and fraud decisions, user-facing experiences, servicing, and more. We are seeking a Software Engineer II to join the Unified Data Platform engineering team. The team is building Affirm's substrate for user-keyed data: a governed, federated layer that replaces ad hoc cross-domain ETL with a single read surface - the data backbone that Affirm's product and ML systems depend on. You will work across organizational boundaries, partnering with domain teams as data producers, collaborating with infrastructure to meet our SLOs, and developing a clear understanding of our analytics and product consumers across online and offline surfaces. You will own correctness and uptime so that downstream teams can build with confidence. We value engineers who think in systems, are rigorous about data contracts and lineage, and communicate clearly across domain boundaries. Strong candidates care about building durable shared platforms, are comfortable shaping architecture in an early-stage buildout, and take personal ownership over the correctness guarantees that other teams depend on. What You'll Do * With the support of your team's tech lead and manager, you will break down larger projects into individual tasks, deliver them in multiple phases, and collaborate with others to ensure timely delivery of your work. * You will support your peers and stakeholders in the product development lifecycle by collaborating across engineering, articulating technical constraints, and partnering on decisions that properly consider risks and trade-offs. * You will support the operations and availability of your team's artifacts by creating and monitoring metrics, escalating when needed, and supporting "keep the lights on" & on-call efforts. * You will contribute to a sense of community on your team by engaging in growth and development activities such as participation in the interview process., To help us assess our outreach efforts, we invite candidates to voluntarily share information through a short demographic survey.
