Job description

Uncountable is the #1 AI platform for end-to-end product development, covering R&D, QC, QMS, and PLM. We help scientists and product teams in materials science, chemistry, and etc move faster — from first experiment to finished product.

We're looking for motivated graduates 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)

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

It's a plus if you:

• Speak another language besides English
• Have a science, chemistry, or materials-related background
• Have done any cold outreach, sales, or customer-facing work (even part-time or university societies count)
• Have worked or interned at a startup before

Compensation

• 33 days annual leave (25 + 8 bank holidays)
• Private Medical Insurance
• Workplace pension via NEST (5% employee + 5% employer match)
• Access to Enterprise Plan with Claude
• Free lunches, dinners, and socials
• Hybrid work with access to our London office (Borough Market)
• Direct mentorship from founders and senior sales leaders
• Any questions please reach out to the hiring manager Bill Qin
• Merit-based promotion — we move fast with people who perform

You must have the right to work in the UK. We are not able to sponsor visas for this role.
