Location: Barcelona, On-site
Mainder is an AI-powered recruitment platform helping companies transform the way they attract, manage, and hire talent.
We build smart workflows that make recruiting faster, more efficient, and more connected — combining AI sourcing, candidate engagement, operational efficiency, and talent intelligence in one place.
We already work with companies across multiple markets and are now entering an exciting new stage of growth. At Mainder, we move fast, learn constantly, and work closely across teams to build products that create real impact for our clients.
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.
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.
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
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
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
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
