Affirm provides a financial platform that offers consumers flexible payment options for purchases without hidden fees or compounding interest. The company focuses on scaling engineering systems and developer productivity through advanced testing infrastructure.

• Design, build, and maintain scalable systems for synthetic identities, test data seeding, mocking, load testing, and deterministic validation workflows;
• Evolve the testing strategy from E2E-heavy validation toward a scalable model with component, integration, contract, performance, and targeted E2E testing;
• Build platform capabilities that make production-like load testing safer, more repeatable, and easier to operate;
• Improve the test platform to ensure it is reliable, observable, and easy for other teams to adopt;
• Partner with product engineering and infrastructure teams to improve test signal quality, reduce false failures, and support faster validation loops;
• Lead medium-to-large technical projects from problem definition through design, implementation, rollout, and operational ownership;
• Improve reliability and operational maturity through dashboards, SLOs, alerts, runbooks, and clear ownership models;
• Reduce manual operational load for load testing, including test data creation, environment setup, reporting, and failure diagnosis;
• Write high-quality, maintainable code;
• Contribute to technical specs, RFCs, ADRs, and project plans;
• Review code and technical designs, provide constructive feedback, and help raise engineering standards;
• Mentor engineers and help build a culture of practical testing excellence.
