Mattermost is seeking a Senior Account Executive, Enterprise to own and grow a portfolio of strategic enterprise accounts across the Americas — with a sharp focus on net-new pipeline generation, executive-level engagement, and complex deal execution. This is a hunter-first role. You will be responsible for identifying and closing new enterprise logos, expanding Mattermost’s footprint within high-value accounts, and navigating multi-stakeholder buying processes across IT, security, procurement, and executive leadership. You’ll work closely with defense-aligned prospects and Fortune 500 customers who rely on Mattermost for mission-critical collaboration. 

If you thrive in high-stakes enterprise sales environments, are energized by complex deals with real-world impact, and want to sell software that genuinely matters to the organizations that depend on it — this is your opportunity. 

What You’ll Do 

  • Own a portfolio of enterprise accounts across the Americas, driving net-new revenue and strategic expansion within existing customers. 
  • Build and execute territory plans including target account mapping, whitespace analysis, and outbound prospecting strategies. 
  • Lead the full sales cycle from outbound prospecting and discovery through demo, negotiation, and close for enterprise deals. 
  • Engage confidently with VP- and C-level stakeholders across IT, security, procurement, and business units to position Mattermost as a strategic platform. 
  • Deliver compelling product demonstrations and value-based presentations tailored to technical, business, and executive audiences. 
  • Partner cross-functionally with Sales Engineering, Customer Success, Product, and Marketing to drive deal velocity and ensure successful customer outcomes. 
  • Lead contract negotiations, ensuring alignment between customer outcomes and Mattermost’s commercial objectives. 
  • Maintain rigorous pipeline hygiene, accurate forecasting, and account documentation in Salesforce. 
  • Represent Mattermost at industry events, conferences, and customer engagements relevant to defense, security, and critical infrastructure. 

What We’re Looking For 

  • Proven enterprise sales experience in SaaS or enterprise software, with a demonstrated track record of closing complex, multi-stakeholder deals at the senior level.
  • Based on the U.S. East Coast (required)
  • Demonstrated ability to run a full sales cycle from cold outbound to close within large enterprise accounts ($100K+ ACV). 
  • Strong consultative selling skills — you ask great questions, listen deeply, and map solutions to business outcomes. 
  • Confidence and credibility engaging VP- and C-level stakeholders across technical and business functions. 
  • Experience delivering effective product demonstrations and articulating technical value to non-technical buyers. 
  • Proficiency with Salesforce; fluency in MEDDPICC or a comparable enterprise sales qualification methodology. 
  • Excellent written, verbal, and presentation skills; comfortable working asynchronously in a remote-first environment. 

Nice to Have 

  • Experience selling into enterprise SaaS, cloud, or platform environments with complex technical buying cycles.
  • Familiarity with cybersecurity, compliance, DevOps, or secure collaboration platforms — comfort navigating security and IT conversations with enterprise buyers.
  • Experience working alongside technical teams such as Sales Engineers or Solution Architects to advance and close deals.
  • Existing relationships or network within Fortune 500 IT, security, or engineering leadership.
  • Background selling into highly regulated industries such as financial services, healthcare, or critical infrastructure.
  • Prior experience at a high-growth, remote-first, or open-source software company.

How Success Is Measured 

  • Quota attainment: consistent achievement of enterprise ACV and ARR targets. 
  • Pipeline generation: self-sourced pipeline as a percentage of total pipeline created. 
  • Deal quality: average deal size, sales cycle length, and win rate across enterprise accounts. 
  • Executive engagement: multi-threaded relationships and documented executive alignment in target accounts. 
  • Cross-functional feedback: positive collaboration scores from Sales Engineering, Customer Success, and Product partners.

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005

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.
