Sales Development Representative (end-of-studies internship or Full-time)

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.

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 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.

Why join Costory

• 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.
