Inside Sales Representative (ISR) / Sales Development Representative (SDR)

Carrollton, Texas

At LiquidStack, we’re redefining what’s possible in the data center world. As a global leader in advanced liquid cooling solutions, we’re powering the future of AI, edge computing, and high-performance systems. Our team is growing, and we’re looking for skilled professionals who want to be part of something innovative and impactful.

Are you comfortable picking up the phone, cold calling, researching companies, and finding the right person to talk to?

LiquidStack is hiring an Inside Sales Representative / Sales Development Representative (SDR) to help our commercial sales team identify new customers and build our sales pipeline.

B2B sales experience is not required.

We are looking for someone who is motivated, persistent, curious, confident on the phone, and willing to do the research necessary to find potential customers and decision-makers.

If you have experience in inside sales, outbound sales, lead generation, recruiting, account development, customer-facing sales, or business development, we want to hear from you.

What You’ll Do

  • Make outbound cold calls to prospective customers.
  • Research companies and identify potential new customers.
  • Find decision-makers, influencers, and key contacts within target companies.
  • Use LinkedIn, company websites, online research, and prospecting tools to identify the right people.
  • Conduct outbound outreach through phone, email, and LinkedIn.
  • Generate and qualify new sales leads.
  • Schedule discovery meetings for the commercial sales team.
  • Build targeted prospect and account lists.
  • Consistently follow up with prospective customers.
  • Build and maintain a pipeline of sales opportunities.
  • Track calls, emails, contacts, leads, and follow-up activity in the CRM.
  • Partner with Sales and Marketing on lead-generation initiatives.

What We’re Looking For

  • 1–3 years of sales, recruiting, lead generation, customer engagement, account development, or related experience preferred.
  • B2B experience is a plus, but not required.
  • Comfortable with cold calling and outbound prospecting.
  • Strong online and company research skills.
  • Comfortable using LinkedIn to research companies and people.
  • Confident communicating with people you have never met.
  • Persistent and comfortable with rejection and follow-up.
  • Self-motivated, competitive, curious, and goal-oriented.
  • Strong written and verbal communication skills.
  • Organized with strong follow-through.
  • Willing and able to learn technical products and terminology.
  • Salesforce, HubSpot, LinkedIn Sales Navigator, CRM, or prospecting-tool experience is a plus.
  • Bachelor’s degree preferred or equivalent relevant experience.

You’ll Thrive Here If...

You enjoy the hunt.

You like researching a company and figuring out who’s who, who makes the decisions, and how to reach them. You aren't discouraged when someone doesn't answer your first call. You are willing to call again, try another contact, send an email, research LinkedIn, and find another way into the conversation.

You are curious, coachable, and interested in building a career in sales.

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 07/31/2029

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
