About Baton

Baton equips business owners and buyers with a modern, data‑driven marketplace to buy or sell, offering valuations grounded in real financials and allowing them to close deals 2x faster than the industry norm. We recently closed our Series A to scale this vision further. We are proud to be building in person in New York City.

• Rapid momentum — We’s gaining traction quickly & our valuation tools, off‑market listings, and streamlined closing processes are changing how small business deals happen at scale.

• Ownership from day one — As a small, lean team, every hire carries outsized impact; from shaping product direction to building a culture of customer‑first execution.

• In‑person energy & collaboration — Based in NYC, we foster a tight‑knit, energetic team environment where voice matters and decisions move fast.

• Mission with heart — We’re clearing the path for small business owners to take meaningful steps forward by providing them clarity, speed, and confidence when it matters most.

• World‑class investors & runway for impact — Backed by Obvious, Giant Ventures, Divergent, Trust Fund, Burst Capital, Bloomberg Beta, and others, our Series A sets a deliberate course for growth and meaningful scale.

• 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.

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 build agentic 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 quickly and 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 ause 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.

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.
