at Lumen Energy

🏢 About Lumen Energy

Lumen Energy is a mission-driven startup using data and AI to accelerate the transition to clean energy in commercial buildings. Their focus on economically optimal solutions sets them apart, offering interns a chance to contribute directly to climate impact while learning cutting-edge sales tech.

About This Role

As an SDR Intern, you'll be the tip of the spear for growth, cold-calling and emailing prospects to book meetings for the sales team. This role is impactful because you'll help refine their Ideal Customer Profile and directly influence revenue, all while gaining hands-on experience with AI-powered outreach tools.

💡 A Day in the Life

You'll start by reviewing your queue of target accounts and drafting personalized email sequences in HubSpot. Midday, you'll make cold calls and send LinkedIn messages, then log all activities. Afternoons are for analyzing response rates and experimenting with new outreach angles alongside the sales team.

🎯 Who Lumen Energy Is Looking For

  • A resilient self-starter who thrives on rejection and sees cold calling as a challenge, not a chore.
  • A concise writer who can craft personalized, non-spammy outreach that cuts through the noise.
  • A detail-oriented operator who logs every interaction in HubSpot and follows up relentlessly.
  • A curious researcher who digs into target accounts to find the perfect angle for each prospect.

4

Demonstrate your writing skills by including a sample cold email or LinkedIn message in your application.

Research Lumen Energy's product and target market (commercial real estate, facility managers) and mention why you're excited about clean energy.
