Now, we’re looking to strengthen our commercial team with ambitious people who want to grow fast and help us build a high-performance sales function from the ground up.

About the Role

We’re looking for 3 Sales Development Representatives (SDRs) to join our team in Barcelona and become part of the foundational core of our sales team.

This is a high-impact opportunity for people who want to learn fast, work hard, and grow quickly inside a modern B2B AI startup. You will play a key role in generating new business opportunities, opening conversations with potential clients, and helping us build a strong, ambitious, and high-performing commercial engine.

It’s a great opportunity for someone interested in:

• Building a career in B2B SaaS sales

• Learning how a fast-growing AI startup operates from the inside

• Developing strong commercial, communication, and operational skills

• Growing into future roles such as Account Executive, Revenue Operations, or SDR Team Lead

This is not a passive role. It requires energy, consistency, resilience, and a genuine desire to improve every week. But for the right person, it can become a real acceleration path.

What You’ll Do

• Execute high-volume outbound prospecting, with a strong focus on cold calling potential B2B clients

• Generate and qualify sales opportunities with real closing potential

• Research target accounts and contacts to better understand their needs and tailor your outreach

• Manage, update, and prioritize leads in the CRM

• Work closely with the Account Executive team — currently in direct collaboration with the CEO and Founder — to hand over well-qualified opportunities

• Contribute to improving sales scripts, outreach messages, and prospecting cadences

• Track and report your activity and performance, including calls, emails, meetings booked, and conversion rates

• Actively participate in team meetings, training sessions, and feedback conversations

• Help build a strong team culture that is ambitious, collaborative, competitive, and healthy

What We’re Looking For

We are open to candidates with different levels of experience, but we are looking for a very specific mindset. We want people who:

• Have strong commercial drive and are not afraid to pick up the phone

• Understand that success is not just about activity, but about generating qualified opportunities

• Are resilient and able to stay motivated even when rejection is part of the process

• Are eager to learn, improve, and receive constant feedback

• Want to grow professionally and see this role as a real development opportunity

• Can work with discipline, focus, and consistency

• Bring a positive attitude and know how to contribute to a strong team environment

• Communicate clearly and confidently in Spanish, both spoken and written

• Have the legal right to work in Spain

Nice to Have

These are not required, but they will be a strong plus:

• Previous experience in sales, customer service, call centers, or telemarketing

• Exposure to B2B sales or startup / scaleup environments

• Genuine interest in SaaS, AI, HR Tech, or Talent Tech

• Familiarity with CRM tools such as HubSpot, Salesforce, or Pipedrive

• Ability to communicate in English in international environments

What We Offer

• The opportunity to join a fast-growing AI company with a real product, real clients, and real market traction

• Direct exposure to the business, the commercial strategy, and the founding team

• A fast-learning environment where performance and development go hand in hand

• A clear growth path within the company

• The opportunity to evolve into roles such as:

  • Account Executive

  • Revenue Operations

  • SDR Team Lead

• A team that is ambitious, close-knit, and excited about building something meaningful

Hiring Process

• Interview with the Talent / Operations team

• Business case / roleplay
