The Baton Way

AI has unlocked a step change in what’s possible in this market — and in how Baton operates. Our goal isn’t to bolt AI onto existing workflows or launch a chatbot; it’s to re-architect how the product works, how internal operations run, and how value compounds across the platform. Engineers here use AI as a force multiplier in their own work and in what they ship — and we take the craft of production AI seriously.

How we build AI at Baton: We buildagentic systems that handle real customer interactions and business workflows end-to-end. Expect to work across the full loop — from problem framing → data → evals → iteration → deployment → monitoring → continuous improvement; grounded in measurable outcomes (quality, latency, cost, reliability). We care about shipping quicklyand building systems that hold up in the real world. We build in person in NYC because this work moves faster and gets better when the team is in the room together. We value low ego, high respect, direct communication, and real ownership.

Why join us:Baton has real momentum — we’re gaining traction quickly, and our valuation tools, off-market listings, and streamlined closing process are changing how small business deals happen at scale. Because we’re still a small, lean team, every hire has outsized impact: you’ll help shape product direction, build core systems end-to-end, and raise the bar on customer-first execution. And the work has real meaning — when we do our job well, we give small business owners clarity, speed, and confidence at one of the most important financial and personal moments of their lives.

About the Role

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 isnot 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.

What You'll Do

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 infrastructurethat supports production-level inference, evaluation, and monitoring
Work across the stackto 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

About You

We're looking for someone who has:

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 have:

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

You'll thrive here if you:

Want to apply AI to real business problems at real stakes and scale—not just build demos
Love small, high-trust teams with meaningful ownership over agents & capabilities that differentiate the product
Prefer shipping to production and measuring performance over endless tinkering
Are passionate about helping small business owners navigate one of the most significant moments in their journey
Can balance “good enough for now” with maintainable, scalable systems—pragmatic about simple solutions vs complex models
Embody low ego, high respect—direct, thoughtful communication; strong feedback muscle

If this sounds like you, we’d love to hear from you — send a note with a few bullets on what you’ve shipped (especially production AI systems you’ve owned end-to-end), and what you’d be excited to build at Baton.
