Sales Development Representative - Mining

Be the tip of the spear for our mining vertical. Research mining companies, labs and consultants, reach out to technical contacts, qualify interest, and book meetings for the sales team. Part-time, remote in Germany.

We're building the operating system for materials analysis

Right now, geologists spend far too much time battling outdated tools just to get minerals data. That slows down every step. We're fixing it! In just 18 months, Momentum Transfer has gone from spinout to seed-funded startup to the go-to platform for synchrotron-quality powder X-ray diffraction as a service. More than 2,300 users already rely on us to provide state of the art mineralogy data. Now we're expanding our mining services — where understanding mineralogy isn't academic, it's the difference between a profitable operation and a write-off. This is where you come in: you'll open the conversations that turn that capability into customers.

Tasks

The Role

You'll research mining companies, projects, labs and consultants, find the people who feel mineralogy problems most acutely — geologists, metallurgists, process engineers and lab managers — and reach out by phone and email. You'll qualify needs and timing, book qualified meetings for the senior sales team, and keep the CRM clean so the whole team can see what's happening. You'll also feed what you learn in the market back into our outreach, helping sharpen the messaging as we build this vertical. Remote role with flexible hours, around 50% availability.

Requirements

The Mindset

This role is the tip of the spear. You'll be the first person a mining company hears from, so you need to be comfortable picking up the phone, writing a sharp email and asking good questions about a technical market you're still learning. Mining moves on credibility and persistence — people won't always reply the first time, and the best opportunities come from staying in touch and being genuinely useful. You don't need to be the expert who closes the deal; you need to find the right people, spark real interest, and hand the senior sales team meetings worth having.

What we need

• Based in Germany
• ~50% availability (part-time)
• Native-level English
• SDR/BDR or outbound appointment-setting experience
• Comfortable calling prospects — cold outreach doesn't scare you
• Strong written communication
• Organized, reliable and self-driven
• Able to work from home

Nice to have

• Spanish
• Mining, lab services, scientific, SaaS or technical B2B experience
• CRM or LinkedIn Sales Navigator experience

Not for you if

• You dislike cold calling
• You need every step scripted
• You give up quickly when people don't reply

Benefits

Why join us

You'll get real responsibility from day one and own the very top of the funnel for a new market.

Remote, flexible hours, fair pay — and plenty of room to grow as the business grows.

We love our team. We love our work.
Please think hard about this.
