Sales Development Representative (SDR)

End-of-studies internship (6 months) or Full-time

Paris (hybrid) · Early-stage startup

What is Costory?

Cloud costs are growing fast. Engineering teams spend too much time figuring out who is spending what — hunting through AWS bills, maintaining brittle spreadsheets, fielding monthly pings from Finance.

Costory fixes that. We automate cloud and AI cost allocation so infra teams get visibility per team, per service, per feature — without the manual work. Think: automated Slack reports, real-time deviation alerts, one-click setup.

We're 30+ customers in, growing fast, and now building the sales motion that'll take us to the next level.

The role

You'd be our first sales hire. No playbook yet — that's partly the job.

Your core mission: fill the pipeline with qualified meetings with the right people (DevOps engineers, SREs, cloud platform leads) at the right companies (50–2,000 employees, meaningful AWS/GCP/Azure spend).

This starts as a classic SDR role — prospecting, outreach, booking meetings. But if you've got the instinct for it, there's a clear path to owning deals end-to-end as a transactional AE. For the internship track: strong performers convert to a full-time SDR or AE role at the end of the 6 months.

What you'll do

Build and execute outbound sequences targeting infra engineers and technical leads

Research prospects and tailor your outreach (no spray-and-pray)

Qualify inbound leads and convert them into booked demos

Work closely with the founders to refine messaging, ICP targeting, and channel strategy

Learn the cloud/DevOps ecosystem well enough to hold a credible conversation with an SRE or platform engineer

What we're looking for

Final year of a business, engineering, or generalist school (internship) — or 0–3 years in sales, BD, or a customer-facing role (full-time)

Genuine curiosity about the tech world — cloud, infrastructure, developer tools excite you

You write well and adapt your tone to a technical audience (engineers don't want corporate fluff)

Organised, self-sufficient, comfortable with ambiguity

Fluent English is a must — most of your prospects are in Europe and the US. French native or bilingual.

You don't need to know what a CUR export is on day one. But you need to want to know.

What makes this interesting

Selling to engineers is a craft. You'll learn how to do it well — technical empathy, not feature-dumping

Early-stage means real ownership. What you build here is yours

Cloud + AI infrastructure is where most of the growth in software spend is happening. You'll be in the middle of it

Clear path: internship → full-time, SDR → AE if the fit is there

Stack & tools

Clay, Sumble, Lemlist, LinkedIn Sales Nav, HubSpot — and whatever works.

Small team. Real customers. No bureaucracy. Founders who'll work alongside you every day.

If you want to learn B2B sales at a technical startup from scratch — and you're the kind of person who figures things out — this is your shot.
