At GWI, we’re always looking for talented, curious people who thrive on having a meaningful impact. Right now, we’re looking for a Sales Development Representative to play a key role in our Revenue team in London. If that’s you, and contributing to growth motivates you, keep reading. It could be the start of something, well, extraordinary.
Sounds great, what will I be doing?
As our Sales Development Representative, you’ll:
Be the first experience and point of contact for potential new customers at GWI. You’ll play a vital role in building our pipeline - identifying opportunities, starting conversations, and connecting the right people to the right solutions.
A few things you’ll be responsible for:
Identify new business opportunities through outbound lead generation, research, and prospecting
Manage and respond to inbound requests from prospective clients via outreach and email
Secure meetings for the GWI sales organisation
Analyse customer needs and identify potential solutions
Present and explain GWI product offerings
Lead outbound conversations with potential clients across phone, email and video
It’s also a lot of fun - shaking things up is what working for GWI is all about. You’ll need to be flexible, comfortable with continuous change, and working in a fast-paced environment.
What do I need to bring with me?
You’ll need to be able to demonstrate the core skills this role requires. You don’t have to tick all the boxes right away; the important thing is that you’re willing to learn.
Here’s what the team will be looking for in you:
Some experience in a customer-facing or sales-adjacent role (this could include voluntary, freelance, or transferable experience)
Excellent communication and presentation skills
Effective time management and organisation skills
Proficient with standard productivity tools, including MS Office
A considered, attentive approach to building professional relationships
Able to stay focused and maintain progress when faced with challenges and setbacks
Ready to take initiative with your own outreach and build a consistent prospecting routine
A confident communicator and active listener, able to navigate nuanced conversations at all levels
Equally important is attitude. We want people who think big (to make an impact), ask why (to find a better way), and show respect (to everyone, at every level, all the time). Those are our values, and they’re a big part of what we’re looking for in you.
