Software Engineer II, Backend (Unified Data Platform)

Affirm is reinventing credit to make it more honest and friendly, giving consumers the flexibility to buy now and pay later without any hidden fees or compounding interest. 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. What We Look For - You have a total of 1.5+ years of experience as a software engineer. - You have experience designing, developing and launching backend systems and are proficient in one of Python or Kotlin. - You are familiar with the building blocks of distributed systems, and the technologies like AWS, MySQL and Kubernetes. - You have mastered taking a simple problem or business scenario into a solution that interacts with multiple software components, and executing on it by writing clear, easily understood, well tested and extensible code. - You are comfortable navigating a large code base, debugging others' code, and providing feedback to other engineers through code reviews. - Your experience demonstrates that you take ownership of your growth, proactively seeking feedback from your team, your manager, and your stakeholders. - You have strong verbal and written communication skills that support effective collaboration with our global engineering team. Location - Remote Canada This remote role is open only to candidates residing in Alberta, British Columbia, Manitoba, New Brunswick, Newfoundland and Labrador, Nova Scotia, Ontario, Prince Edward Island, or Saskatchewan.
