The Opportunity:

We're looking for a driven Enterprise Expansion Account Executive to own and grow revenue within Arize's existing customer base. You'll work with AI engineers, Data Scientists, and platform teams who are already using our Enterprise platform - helping them unlock more value, expand into new teams, and deepen their investment as their AI initiatives scale. This is a high-impact, high-ownership role at the intersection of a fast-moving product and a customer base growing rapidly alongside the AI industry.

What You’ll Do:

• Own the full expansion and renewal sales cycle across your book of business, executing a complex, value-based process that spans multiple stakeholders, teams, and use cases within each account.
• Proactively identify and develop new growth opportunities by analyzing customer usage, mapping whitespace, and targeting high-value needs across business lines and technical teams.
• Build and maintain executive relationships, creating awareness and buy-in at the VP and C-suite level to support pipeline growth and long-term account expansion.
• Define and execute account strategies in close partnership with Solutions Managers and internal account teams to drive sales velocity and deliver customer outcomes.
• Clearly articulate Arize's unique value - technically and commercially - tailoring your message to both technical practitioners and business decision-makers.
• Forecast accurately and consistently, leveraging key metrics and pipeline data to provide visibility and inform go-to-market decisions.
• Maintain rigorous hygiene in Salesforce, tracking all activity, opportunities, and account intelligence to support a highly performing revenue team.
• Travel as needed to build relationships and engage customers on-site.

What We’re Looking For:

• 5+ years of B2B SaaS sales experience
• Proven track record of driving expansion and upsell revenue within Enterprise accounts, bonus for selling AI/ML or data infrastructure software to VP and C-suite stakeholders.
• Demonstrated success building and deepening executive relationships across Global 2000 organizations, engaging both technical leaders (AI/ML, data engineering, platform) and business decision-makers.
• Expertise in developing multi-year account plans that expand Arize's footprint by aligning product value to evolving customer needs and AI initiatives.
• Established ability to manage a robust and diverse pipeline of expansion opportunities, balancing near-term wins with long-term strategic growth within a collaborative go-to-market team.
• Team player: Collaboration with peers and other organizations within Arize is critical to success, we deeply value the success of the collective team over individual gains
• Strong communication skills: Clearly and objectively communicate observations from the field
• Previous history of also working and closing new business deals and selling through product led experience

The estimated annual salary and variable compensation for this role is between $250,000 - $300,000, plus a competitive equity package. Actual compensation is determined based upon a variety of job related factors that may include: transferable work experience, skill sets, and qualifications. Total compensation also includes a comprehensive benefit package, including: medical, dental, vision, 401(k) plan, unlimited paid time off, generous parental leave plan, and others for mental and wellness support.
