About The Position

As a Software Engineer, you’ll work directly with our Head of Engineering and product team to build the agentic platform that powers how small businesses are bought and sold. Your work will directly impact how thousands of owners navigate one of the biggest financial moments of their lives. This is not a papers-and-prototypes role, it’s product engineering with real AI systems. You’ll ship full-stack agentic systems end-to-end, collaborate closely with sales and operations, and turn real business needs into agentic product experiences that users interact with daily. AI isn’t a separate track at Baton, it’s embedded into how product is conceived, built, shipped, and improved. If you’re the kind of engineer who wants to own the full loop — from “what problem matters?” to “it’s in prod and we’re monitoring it” — you’ll be at home here.

Requirements

• Shipped and owned production AI systems end-to-end (LLM and/or classic ML) — real users, measurable outcomes, operational responsibility
• Strong software engineering fundamentals with excellent Python skills and experience integrating foundation models in production
• A track record of shipping — you’ve taken ambiguous problems from concept → production and can point to impact
• Strong product sense — you can be your own product manager when needed, translating business needs into technical solutions without waiting for a spec
• Comfort in ambiguity — you thrive with limited structure and turn uncertainty into clarity

Nice To Haves

• Experience with modern AI frameworks and building multi-step agentic systems with tool use, planning, and human-in-the-loop patterns
• Experience designing evaluation suites for LLM systems (offline + online), including rubric-based and model-graded evals
• Experience operating LLM systems at scale—latency, cost, caching, fallbacks, rate limits, reliability
• Familiarity with retrieval quality work—chunking, reranking, query rewriting, relevance tuning
• Marketplace, platform, fintech, or small business background with understanding of matching algorithms or business transactions
• Familiarity with Go, GraphQL, or React/TypeScript
• Background in NLP, information retrieval, or recommendation systems

Responsibilities

• Ship full-stack AI features end to end — from scoping with stakeholders to deploying agentic systems that solve real problems for buyers and sellers
• Own 0-to-1 projects, collaborating with our sales & operations teams to identify high-leverage opportunities and build intelligent capabilities
• Build and improve agentic infrastructure that supports production-level inference, evaluation, and monitoring
• Work across the stack to integrate AI seamlessly into our marketplace, creating clean interfaces that make intelligent features feel native to the product
• Develop tools and systems that scale — from intelligent matching to document understanding and agentic workflows that transform our marketplace

Benefits

• Competitive compensation & perks — Expect market‑competitive pay, equity, fully-covered health benefit options, flexible time off, commuter perks, in-office snacks, and a true culture of low ego and high respect.
• Employer contribution for all healthcare options
• 401k plan / short-term disability
• Four weeks of paid time off, generous sick leave, and six weeks of flexible Work From Anywhere days
• On-demand mental health support from Spill
• Laptop of your choice
• Parental leave program
• The opportunity to make a meaningful impact on the lives of small business owners and their communities
