About the role

The work is taking messy business problems (fragmented knowledge, manual processes, disconnected tools) and turning them into working software: agents, APIs, applications, and infrastructure.
Your job is to turn their rough applications and processes into production systems, and to push back when a technical constraint changes what's possible.
Hosting, security, deployment, and ongoing maintenance are all part of the job.

Build and ship AI agents, APIs, and applications on Affirm's internal platform (Snowpark Container Services / Quicksilver). You own the full lifecycle: architecture, containerization, networking, secrets, CI/CD, monitoring, and fixing what breaks.
You figure out what's allowed, build within those constraints, and make sure employee data stays where it's supposed to.
Design reliability infrastructure for multi-model LLM services. Structured output validation, fallback chains, circuit breakers for external APIs, and quality controls that catch hallucination before users see it.
Own what you build. When something breaks in production, you diagnose and fix it.
You will build AI systems that directly change how 2,000+ employees interact with the People function. Visible, measurable impact.
You will build AI systems that directly change how 2,000+ employees interact with the People function.

You have built, deployed, and maintained production applications.
You can make architecture decisions, evaluate trade-offs, and read code well enough to know when something is wrong.
The team works primarily in Python, and you should be comfortable in it, but the ability to think in systems matters more than raw coding skill.
You have created something from nothing: a system, a tool, a platform, in an environment where nobody handed you a spec.
Ability to work across the technical-business boundary.
You can sit in a meeting with non-technical stakeholders, understand the real problem behind the stated request, and come back with a solution that actually addresses it.
