Sales Development Representative

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)

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 German
• 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)
• Remote-first with access to our London office (Monument / Borough)
• Direct mentorship from founders and senior sales leaders
• 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.

We\’re building something meaningful in a technically rich space. If you want to grow fast, be taken seriously, and work on something that matters — apply.
