About the Company

Our client is a fast-growing technology business in the adtech and SaaS space, providing an advanced demand-side platform (DSP) that helps marketers drive performance and growth through data-driven, automated advertising solutions. The platform combines powerful AI, flexible campaign tools, and seamless integrations to help mid-sized businesses simplify complexity and turn clicks into customers.

The business has a global presence with teams across North America, Dublin, Sydney, and the UK, and is now expanding its London footprint.

The Role

This is an exciting opportunity to become the first UK hire within the sales development team. You'll be responsible for pipeline generation - engaging new prospects, qualifying leads, and driving interest that supports the wider sales function.

This is not a full-cycle closing or pure tech sales role but a crucial front-end position for building new business opportunities. You'll work closely with a highly experienced Account Executive already based in London and be part of a collaborative, globally connected team.

Key Responsibilities:

• Drive outbound prospecting efforts through calls, emails, and social outreach

• Manage inbound leads while maintaining a strong focus on outbound activity

• Book and qualify meetings for senior Account Executives

• Conduct research on target accounts and key decision-makers

• Maintain a healthy pipeline using CRM tools

• Work closely with internal teams to ensure smooth handover of qualified opportunities

What We're Looking For

• Previous sales or business development experience (SDR, BDR, or Inside Sales background)

• Proven track record in cold calling and prospecting

• High level of resilience, motivation, and hunger to succeed

• Excellent communication and interpersonal skills

• Strong organisational and preparation skills (especially for interviews and roleplays)

• A go-getter attitude with the ability to overcome rejection and challenges

Desirable:

• Experience in AdTech or SaaS sales

• Exposure to technology or digital media environments

• A passion for building a long-term sales career with a clear path to Account Executive level

Benefits

• Competitive salary and equity

• Subsidy for individual medical and dental insurance cover

• Four weeks of paid annual leave plus company holidays

• Up to 52 weeks of maternity leave / 12 weeks of paternity leave

• Strong work/life balance and hybrid flexibility

• Employee Resource Groups and volunteer opportunities with local organisations
