Uncountable is the #1 AI platform for end-to-end product development, covering R&D, QC, and PLM. We help scientists and product teams in materials science, chemistry, and biology move faster — from first experiment to finished product.
We're looking for a motivated graduate to join our UK sales team as an SDR. This isn't a shadowing role or a coffee-making internship. From week one, you'll be generating real pipeline, working directly with founders and senior sales leaders, and building skills that will define your career in tech.
Responsibilities
- Drive pipeline through cold calling — phone is your primary weapon here, so confidence on a call matters
- Find and qualify new business opportunities through outbound prospecting (email, LinkedIn, and cold calls)
- Work hand-in-hand with an experienced Account Executive to build and convert pipeline
- Step in for introductory demos when the moment calls for it — not a core expectation, but you'll be ready
- Use industry-leading tools: Salesforce, ZoomInfo, LinkedIn Sales Navigator, Gong
- Team up with marketing to align on messaging and campaigns
- Learn the industries we serve — you don't need a science degree, but curiosity is a must
- Travel to conferences and events across the EU, with opportunities to go global (~25% of the time)
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Qualifications
- No prior sales experience required — but you'll thrive here if you're:
- Driven and resilient — startups are fast-paced and targets are real
- Organised and analytical — you'll manage a large lead pool and need to prioritise smartly
- A natural communicator — confident reaching out cold and representing the brand
- Genuinely curious — about tech, science, and how businesses work
