Staff Software Engineer, Full-Stack (Account Management)

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.

Account Management owns the customer-facing self-service channels and the agent portal tooling that frontline support and customers depend on — operationally critical surfaces that directly affect customer experience, support efficiency, and fraud/risk outcomes. As we shift the platform toward agentic account updates and consolidate agent tooling, the scope, cross-service integrations, and vendor touchpoints grow substantially; this increases technical risk and the need for rigorous, end-to-end technical stewardship.

We’re hiring a Staff Software Engineer / Technical Lead to be the team’s consistent technical owner: you’ll set technical direction, make architecture and rollout tradeoffs, and own operational readiness — observability, incident playbooks, and structured post-launch validation. You’ll lead designs for agentic workflows and Self Service Account Management features, reduce coupling across event-driven integrations, and codify the patterns and guardrails that make self service, agentic account updates, and agent tooling safe, auditable, and scalable.

Beyond hands-on delivery, this role is about leverage: unblocking senior engineers, raising engineering standards through rigorous design and code review, and coordinating delivery across Product, Operations, and partner engineering teams. We value pragmatic engineers who combine deep technical judgment with a collaborative, outcomes-focused mindset, a commitment to operational excellence, and a bias for clear, measurable launches that minimize reliability and compliance exposure.

• You will be responsible for setting technical strategy for your team on a year-long time scale, and help your team tie it together with critical, business-impacting projects.
• You will collaborate across teams in the product development lifecycle by collaborating with product management, design & analytics to ensure technical sustainability, risks and trade-offs are well understood and managed.
• You will act as a force-multiplier for your team through your definition and advocacy of technical solutions and operational processes.
• You take ownership of your team’s operations and availability by ensuring you have the right monitoring, triage rotations, playbooks, polcities, testing and alerting in place to support “keep the lights on” & on-call efforts.
• You will foster a culture of quality and ownership on your team by setting code review and design standards for your team, and advocating for them beyond your team through your writing and tech talks.
• You will help develop talent on your team by providing feedback and guidance, and leading by example.

• You have a total of 8+ years of experience as a software engineer.
• You are proficient in designing, developing and launching backend systems at scale technologies like Python, Kotlin, AWS, MySQL, and Kubernetes
• You are proficient in developing web apps using declarative UI frameworks like React or Vue.
• You have experience delivering major features, system components or deprecating existing functionality in a system through the definition of a technical and execution plan. You write high quality code that is easily understood and used by others.
• You thrive in ambiguity, and are comfortable moving from low level language idioms all the way to the architecture of large systems to understand how they work.
• Your growth and impact trajectory demonstrates that you have mastered gathering and iterating on feedback from your engineering and cross-functional peers.
• You have strong verbal and written communication skills that support effective collaboration with our global engineering team.
