## About the Role

Software Engineering, Sales, Small Business, Artificial Intelligence (AI), Retrofit, Multiplatform/Cross-Platform, Continuous Improvement, Data Analysis, Building Systems, Production Systems, You have shipped and owned production AI systems end-to-end (LLM and/or classic ML) - real users, measurable outcomes, and operational responsibility.
Strong software engineering fundamentals, excellent Python skills, and proven experience integrating foundation models into production systems.
Bonus Skills
Hands-on experience with modern AI frameworks (LangGraph, LangChain, LlamaIndex), vector databases, or LLM observability tooling.
Experience designing evaluation suites for LLM systems (offline and online), including rubric-based and model-graded evals.
Experience running LLM systems at scale - latency, cost, caching, fallbacks, rate limits, and overall reliability.
Familiarity with retrieval quality work: chunking, reranking, query rewriting, and relevance tuning.
A background in marketplaces, platforms, fintech, or small business, with a grasp of matching algorithms or business transactions.
Familiarity with Go, GraphQL, or React/TypeScript.

Comfort with ambiguity - you do well with limited structure and turn uncertainty into clarity.
First-principles thinking and genuine intellectual curiosity - you dig into problems from the ground up rather than leaning on established patterns.

## Description

Join an AI-native engineering team as a Software Engineer. The engineering org is currently 7 people (a mix of contractors and full-time staff), and everyone is AI-focused. You'll partner directly with the Head of Engineering and the product team to build the AI-native platform powering how small businesses change hands. Your work will directly affect thousands of owners navigating one of the biggest financial moments of their lives.
This is not a papers-and-prototypes role - it's hands-on product engineering with real AI systems. You'll ship full-stack AI projects end-to-end, work closely with sales and operations, and translate real business needs into intelligent product experiences that users engage with every day.
At our client, AI isn't a separate track - it's woven into how products get conceived, built, shipped, and improved. If you're an engineer who thrives on owning the full loop, from identifying the key problem to monitoring it in production, you'll do well here., Ship full-stack AI features end-to-end - from scoping with stakeholders to deploying production systems that solve concrete problems for buyers and sellers.
Own 0-to-1 projects, partnering with sales and operations to find high-leverage opportunities and build intelligent capabilities around them.
Build and refine the AI infrastructure that supports production-grade inference, evaluation, and monitoring.
Work across the stack to integrate AI seamlessly into the marketplace, designing clean interfaces that make intelligent features feel native to the product.
Develop tools and systems that scale - from intelligent matching to document understanding to agentic workflows that reshape how the marketplace operates.
