Company mission
To deliver honest and transparent financial products that improve users' lives.
Role
Who you are
- You have 8+ years of experience designing, developing, and launching backend systems at scale using languages like Python or Kotlin
- You have an extensive track record of developing highly available distributed systems using technologies such as AWS, MySQL, Spark, and Kubernetes
- You have experience building or evolving shared backend platforms that support Rewards, Loyalty, Incentives, Experimentation, or other growth-critical workflows used by multiple product teams
- You have led complex technical initiatives that required cross-team alignment, long-term architectural thinking, and influence without direct authority
- You have experience delivering major features, system components, or deprecating existing functionality through the definition and execution of a clear technical 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 to the architecture of large-scale systems to understand how they work end to end
- Your growth and impact trajectory demonstrates that you have mastered gathering, incorporating, and iterating on feedback from engineering and cross-functional peers
- You have strong verbal and written communication skills that support effective collaboration with a global engineering organization
- This position requires either equivalent practical experience or a Bachelor’s degree in a related field
What the job involves
- The Growth Platform team builds shared backend platforms that power incentives, experimentation, personalization, and data-driven decisioning across Affirm’s consumer and merchant experiences, directly influencing customer acquisition, engagement, and retention
- You will be responsible for setting technical strategy for your team on a year-long time scale, owning backend platforms that power incentives and growth initiatives across Affirm
- You will collaborate with product management, analytics, and partner teams to shape technical direction for incentive systems, ensuring long-term sustainability, correctness, and clear trade-offs that inform roadmap decisions
- You will act as a force-multiplier by defining platform abstractions, APIs, and architectural patterns that enable product teams to safely launch, experiment with, and evolve incentive-based experiences
- You take ownership of your team’s operations and availability by ensuring robust monitoring, alerting, playbooks, and on-call practices are in place for business-critical incentive and growth systems
- You will foster a culture of quality and ownership by setting clear design and code review standards, and advocating for them beyond your immediate team through written proposals and technical discussions
- You will help develop talent on your team by providing actionable feedback, technical guidance, and leadership on complex, high-impact systems
Our take
Affirm offers point-of-sale loans to consumers, working with merchants like Shopify, KAYAK, and Walmart. Buy now, pay later transactions have grown in popularity in recent years, and this business is tapping into the market with a totally different approach to credit - by delivering the Affirm card, the first US debit card with the option to pay-over-time.
Boasting over 21M consumers and 337,000+ merchants, the company offers flexible payback options, ranging from 3 to 36 months. The interest rates run between 0% and 30%, so, while they are not necessarily the cheapest option, Affirm prides itself on having no fees for late payments, no hidden charges, and total transparency about what people will pay before they take out a loan.
Affirm collects payments from the customers and pays the merchants directly, shouldering the risk itself. The company has boosted its market share, expanding its availability beyond the US to include most of Canada, and continues to launch new features and create new partnerships towards bettering its offering.
