Beschreibung

• You will own and deliver quarterly goals for your team, leading engineers through ambiguity to solve open-ended problems, and ensuring that everyone is supported throughout delivery. • You will design and implement real-time fraud decisioning services and APIs in Python or Kotlin, extending Affirm's Fraud Decisioning System to markets beyond the US. • You will build and evolve the platform and tooling that let Affirm launch fraud decisioning in a new country quickly—turning market-by-market setup (rules, models, and vendor configuration) into a repeatable, low-friction path so launches scale sub-linearly with the number of markets. • You will integrate region-specific fraud and risk vendors and help operationalize the machine learning and AI signals that power real-time decisioning, while using modern AI tooling to move faster as an engineer. • You will support peers and stakeholders across the product development lifecycle - collaborating with Product, Machine Learning, Analytics, and Fraud Strategy, articulating technical constraints, and partnering on decisions that properly weigh risks and trade-offs. • You will support the operations and availability of your team's systems by creating and monitoring metrics, escalating when needed, and contributing to keep-the-lights-on and on-call efforts. • You will foster a culture of quality and ownership - setting and improving code review and design standards, mentoring teammates, and leading by example. • On-Call Rotation - There would be an on-call rotation for this role as a requirement.

🎯 Anforderungen

• 5+ years of experience building backend systems at scale using Python or Kotlin. • Experience with distributed systems and infrastructure using AWS, MySQL/PostgreSQL, and Kubernetes. • Strong system design skills and a track record of delivering maintainable, extensible services. • Fluency with AI-driven engineering - every Affirm engineer builds with tools like Claude Code and most PRs are co-authored with AI, so directing and orchestrating AI and excelling in the reviewer's seat (setting intent, critically evaluating generated code, and owning its correctness, quality, and security) is a core expectation. • Proficiency in SQL and working with data-rich environments. • Familiarity with CI/CD practices and safe production deployments. • Strong written and verbal communication skills, especially in distributed teams. • A proactive, ownership-driven mindset with a focus on learning and team success. • Experience with Snowflake, dbt, Airflow, or Chronosphere (nice to have) • Background in fraud prevention, risk systems, or real-time decisioning (nice to have) • Experience building for multiple markets or regions - internationalization or localization (nice to have) • Experience working in the fintech sector or other highly regulated environments, with a strong understanding of risk, compliance, and operational constraints. (nice to have)

🏖️ Vorteile

• 100% subsidized medical coverage, dental and vision for you and your dependents • Flexible Spending Wallets for tech, food and lifestyle • Away Days - wellness days to take off work and recharge • Learning & Development programs • Parental benefits • Employee Resource & Community Groups
