About Atomic One

Atomic One is an AI-native managed service for Amazon sellers. Instead of dashboards, we deploy a team of specialized AI agents — PPC, Inventory, Traffic, and 20+ others — that run brand operations end-to-end. We're heading into our MVP go-live, and the next 12 months are about turning a working product into a category-defining one.

The Role

We're hiring a PM to work cross-functionally across the full Atomic One product surface: the agent platform, the client-facing experience, and the free tools (MCP server, P&L; tool) that bring sellers into our funnel. You'll work directly with the Lead PM, and partner daily with engineering, data science, brand managers, and customer support.

This is a high-ownership role at a small, fast-moving company. You'll ship things real users depend on, see your decisions in production within days, and have unusual leverage on what we build.

What you'll do

Own product areas end-to-end: discovery, spec, prioritization, launch, iteration

Translate messy seller workflows into clear product behavior our agents can execute

Work with the data team to define what "good" looks like for each agent and measure it

Sit close to clients and internal brand managers — their feedback is the roadmap

Write crisp specs, decision docs, and PRDs that engineers can actually build from

Build things yourself — prototype, design, and ship with AI tools (Lovable, Cursor, Claude, etc.).



We expect PMs to be hands-on builders, not just spec writers

Stay on the frontier of AI tooling — new tools come out weekly, and you should be the kind of person who tries them, learns fast, and brings the best ones into how we work

Help shape how AI products should feel: trustworthy, transparent, fast

What we're looking for

3–5+ years of overall experience, ideally with 1–2 years as a PM (APM to PM level)

Strong candidates without formal PM experience are welcome if the background is right

Comfortable working with AI/ML products — you understand how LLMs, agents, and model evaluation actually work

Data fluency: you can dig into a dataset, define metrics, and reason about quality without waiting for an analyst

Sharp written and spoken communication in English — fluent, professional, near-native level required

You move fast, ship simple things first, and prefer clarity over polish

Builder mindset — you've used AI tools to design, prototype, or write code yourself, and you're excited to keep pushing what a PM can ship solo

Ecommerce or Amazon seller experience is a strong plus (SP-API, PPC, FBA, SQP — if these mean something to you, tell us)

What you'll get

Ownership of real product surface from day one A team that ships continuously and respects good thinking
