Job Description

Software Engineer II, Backend – Infrastructure Platform

Affirm

• Build a centralized reliability command center that gives teams a unified view of system health, risk, and reliability across services and environments. • Create AI agents that can assist with incident triage, root-cause exploration, log/trace summarization, and recommended next actions. • Create delightful developer-facing features and APIs that help engineers explore data, debug issues, and make better decisions. • Use AI-assisted development tools (e.g., Cursor, Claude, Copilot-like tools) as leverage to prototype, refactor, and ship high-quality code quickly. • Own projects end-to-end: requirements, architecture, implementation, testing, rollout, and iteration based on feedback. • Collaborate closely with partner teams (product, infra, data, SRE) to understand pain points and translate them into simple, powerful solutions.

Job Requirements

  • This position requires either equivalent practical experience or a Bachelor’s degree in a related field
  • Strong proficiency in Python, with experience architecting data-intensive applications and robust APIs
  • Problem-solving and product sense: you care about the "what" and the "why," not just the "how." You are capable of taking ambiguous requirements and rapidly iterating towards a working solution
  • Hands-on experience with AI-assisted development, such as Cursor, Claude, or similar tools, and enthusiasm for using them to build and ship features faster.
  • Practical use of LLMs or AI frameworks to enhance automation and guidance with guardrails and citations

Benefits

  • Health care coverage - Affirm covers all premiums for all levels of coverage for you and your dependents
  • Flexible Spending Wallets - generous stipends for spending on Technology, Food, various Lifestyle needs, and family forming expenses
  • Time off - competitive vacation and holiday schedules allowing you to take time off to rest and recharge
  • ESPP - An employee stock purchase plan enabling you to buy shares of Affirm at a discount
