Job description for Sales Development Representative (SDR) Internship at GTMLab

GTMLab is a growth consultancy. We help businesses across Southeast Asia solve their hardest growth problems and turn the answers into measurable results. Since 2024, we've grown from a small founding team to 100+ people and worked with 500+ clients, from local SMEs to regional enterprises. We're bootstrapped, profitable, and growing fast, which means we answer to our clients and our standards, not to investors. We work the way the best consulting firms do: start with the business problem, not the deliverable. Our job is to figure out what's really holding a company back, build the case for what to do about it, and stay close enough to see it through.

What You'll Do

This role is designed to provide hands-on experience in sales techniques and lead management, offering insights into the sales process and the opportunity to develop critical communication and persuasion skills.

  • Respond to Inbound Leads: Promptly engage incoming chat and message inquiries generated across all advertising channels, assessing fit and readiness while nurturing trust from the first message.
  • Own Prospect Engagement: Actively reach out to potential clients via cold calls, WhatsApp, email, or LinkedIn to introduce our services and initiate meaningful sales conversations.
  • Qualify & Manage Leads: Generate, qualify, and manage leads across both inbound and outbound channels by understanding prospect needs and decision-making context.
  • Conduct Initial Sales Conversations: Handle first-touch discovery calls and chats, answer prospect questions confidently, and clearly communicate our value proposition and service offerings.
  • Drive Meetings & Handoffs: Secure qualified meetings and coordinate smooth handoffs of high-intent leads to our sales teams, ensuring a seamless progression through the pipeline.
  • Maintain CRM & Sales Reporting: Accurately update CRM systems with lead activity, conversations, insights, and outcomes to ensure visibility of pipeline health and performance.
  • Collaborate on Sales Strategy: Partner with the sales teams to refine outreach approaches, messaging, and lead qualification criteria to improve conversion rates.
  • Provide Market & Lead Insights: Share insights on prospect objections, lead quality, and market patterns to help improve targeting and sales strategy.
  • Grow Your Skills: Actively participate in sales meetings and training sessions to deepen your product knowledge and sharpen your sales techniques.


Who We're Looking for

  • Fresh graduates in Business, Marketing, Communications, or a related field.
  • We're also open to applicants from all academic backgrounds, as long as you demonstrate strong communication skills, curiosity, and a genuine interest in sales.
  • Demonstrates excellent verbal and written communication skills, with professional fluency in both English and Bahasa Indonesia.
  • Highly self-motivated, resilient, and target-oriented, with a strong sales mindset, sense of ownership, and a positive, growth-driven attitude.
  • Able to work fully from our office in Menteng, Jakarta Pusat (Fully WFO).

We're not just looking for someone who checks all the boxes for this role; we're looking for a partner in our journey of growth. Someone ready to dive in, contribute to our vision, and help us take things to the next level.

About the company
GTMLab
Marketing and Advertising
11 - 50 employees

GTMLab is a paid growth and GTM strategy consulting firm built on one bet: data and AI, woven through every part of a marketing system, will make the legacy agency model obsolete.

We aren't here to run marketing campaigns. We build growth machines — end-to-end engines where every dollar traces back to real revenue, not vanity metrics.

And we build them as operators who have sat on your side of the table. Before GTMLab, we started and scaled our own companies: raised millions in venture capital, hit ambitious targets, and felt the weight of owning the P&L. We're founders first, Y Combinator alumni and Forbes 30 Under 30 awardees, who've built and scaled businesses across six countries. We run your growth the way we ran our own.
