Senior Account Executive

Antithesis helps engineering teams find and fix bugs that traditional testing misses.

Our platform runs entire systems in a deterministic simulation, breaks them in every imaginable way, and provides engineers with root cause analysis and perfect reproduction. The result is faster debugging, more reliable software, and more confidence in what ships.

As AI accelerates software development, the need for reliable verification is only increasing. Antithesis exists to solve that problem. We are well-funded, deeply technical, and building a category-defining platform for modern software reliability.

Antithesis is looking for Senior Account Executives with experience selling developer tools to customers in the finance industry.

As a Senior Account Executive, you will report either to a Regional Sales Leader or directly to the VP of Sales, depending on location. You will work closely with customers, prospects, and internal teams to drive adoption of Antithesis’s technology.

• Engage senior engineers, engineering leaders, and executives in technical and business-focused sales conversations.

• Help define and refine Antithesis’s customer qualification criteria and sales process as the company scales.

• Represent the voice of the customer in product discussions with engineering and product teams.

• Drive successful customer adoption by clearly articulating value, ROI, and integration considerations.

• Mentor new Account Executives and contribute to a strong, collaborative sales culture.

• Partner with marketing to refine messaging and sales materials based on market feedback.

• Focus on selling into the FinTech and Financial Services sector, with a long-term focus on selling across Wall Street accounts.

• Have 5+ years of experience in full-cycle enterprise B2B SaaS sales, with direct experience selling developer tools or similarly technical products.

• Bring experience selling technically complex SaaS products to financial clients.

• Demonstrate a consistent track record of exceeding quota.

• Be highly motivated, proactive, and comfortable owning pipeline creation and deal execution.

• Possess strong technical acumen and communicate effectively with both technical and executive stakeholders.
