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
- 1.5+ years of experience as a software engineer
- 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
