Founding Product Manager

Who we are

Lemrock builds the infrastructure of agentic commerce.

Tomorrow, consumers won't just buy on e-commerce websites. They will discover, compare and purchase directly inside conversational AI interfaces like ChatGPT, Perplexity, and a growing long tail of specialized AI assistants.

For brands, this is a major shift: if they are not present in these environments, they become invisible.

Our mission: enable any brand to exist, sell and distribute in this new channel.

We raised a €7M seed round (the first in Europe on this market), with Jean-Baptiste Rudelle, founder of Criteo, on our board, and the Bpifrance DeepTech label.

Today, Lemrock is already:

• 100M+ conversations per month

• 150+ brand clients

• a $100B market structuring at high speed

The role

Product at Lemrock has been driven by the founders so far. As our first Product Manager, you'll work directly with the founders and our CTO to shape the product vision, own a core part of the product end to end, and build the practice that takes us from idea to shipped.

You'll start by owning the brand-facing product, and your scope will grow fast from there.

Your mission

• Shape the vision: bring your own conviction to the product strategy with the founders, from what we bet on next to what we stop doing.

• Own the roadmap end to end: turn strategy into a living, prioritized roadmap, and decide what we don't build so the team stays on the highest-impact work.

• Run discovery: spend real time with brands, partners and the field, find the problems worth solving, and validate before we build.

• Ship with the team: work shoulder-to-shoulder with engineering and design to scope, prototype, and ship weekly, not quarterly.

• Own launches and outcomes: drive rollout, watch the data, onboard the business teams, and judge your work by what it moved, not by what shipped.

• Build the product function itself: the rituals, the prioritization, the feedback loop from the field.

What we're looking for

• 3 to 8 years in product, at least part of it at a startup or scale-up, ideally as an early or first PM. You've taken something from a vague problem to a shipped, used feature, and owned its results.

• A generalist comfortable owning the messy middle: discovery one hour, scoping with engineers the next, writing the launch note after that.

• A bias for action: you make calls with incomplete data, ship, and iterate from what real users do.

• Customer obsession that shows up in your decisions.

• AI-native: you already build with tools like Claude, Cursor, v0 or Lovable to prototype, research, synthesize, and move the roadmap faster.

• Able to learn a lot, fast, in a deep and complex environment.

• Fluent French and professional English.

• Based in Paris, with the team at the office (up to 1 day remote per week).

Bonus

• You've built in e-commerce, marketplaces, adtech, or AI/agent products, or you're genuinely fascinated by agentic commerce.

• A technical background (ex-software engineer or CS), so you can go deep with the team and direct AI tools effectively.

Why join us

• Join a company in early breakout mode, already generating revenue with a clear edge.

• Be part of the next structural shift of the web: agentic commerce.

• Work directly with experienced, ambitious founders, and own the product from day one.

• Shape both the product and how we build it.

What we offer

• Competitive salary, based on experience

• Equity (BSPCE)

• Meal vouchers with Swile

• Alan health insurance

• 7 weeks of vacation (RTT included)

• 50% transportation coverage
