Affirm is seeking a Senior Backend Engineer for their Growth Platform team to build scalable systems that drive user acquisition and engagement. You'll work with Java and REST APIs to design core tools that impact millions of customers. This role requires strong backend engineering experience.
You have 5+ years of backend engineering experience, building production systems that are reliable and scalable — you've successfully led projects from design through deployment and have navigated complex challenges in distributed systems. Your expertise in Java is deep, and you understand how to design and implement high-performance REST APIs that serve millions of users. You thrive in collaborative environments, working closely with product management, design, and data science teams to create impactful solutions. You are comfortable with ambiguity and can guide your team through open-ended problems, ensuring everyone is supported and aligned on goals. You have a strong focus on delivering exceptional engineering solutions that enhance user experiences and drive growth.
Experience with event-driven architectures or familiarity with experimentation frameworks would be a plus, as would any background in user engagement strategies. You are eager to learn and adapt, and you enjoy mentoring junior engineers, sharing your knowledge to help them grow.
In this role, you will own and deliver quarterly goals for your team, leading engineers through the complexities of building core systems that drive user acquisition and lifecycle growth. You will collaborate closely with product, data science, and experience teams to design APIs and services that are not only scalable but also enhance customer engagement. Your responsibilities will include overseeing the development of intelligent experimentation frameworks that allow for personalized communications with users. You will ensure that your team is supported throughout the product development lifecycle, facilitating collaboration and communication among stakeholders. You will also be involved in code reviews, system architecture discussions, and performance optimization efforts, ensuring that the solutions you build are robust and efficient.
At Affirm, you will be part of a mission-driven company that is reinventing credit to be more honest and friendly. We offer a flexible remote work environment, allowing you to balance your professional and personal life effectively. You will have the opportunity to work on impactful projects that directly influence how customers experience our products. We encourage you to apply even if your experience doesn't match every requirement — we value diverse perspectives and backgrounds. Join us in building a better financial future for consumers everywhere.
