Antithesis is a well-funded software verification platform that helps engineering teams find and fix bugs through deterministic simulation. The company is pioneering a new approach to testing and debugging for the AI era, addressing verification as a critical bottleneck in accelerated software development.
As Senior Account Executive for the Pacific Northwest region, you will own the full enterprise sales cycle for a category-creating product. This is an early-stage GTM role where you'll develop new business, navigate complex technical evaluations, and help customers understand novel solutions to problems they may not yet recognize. You'll work with a defined territory covering technical ICPs (software engineers, engineering managers, architects, VPs of Engineering, CTOs) and business stakeholders.
Key responsibilities include:
- Owning the complete sales process from prospecting through close, including qualification, technical evaluation, negotiation, and deal progression
- Building and maintaining a healthy pipeline across your territory, engaging both technical and executive buyers
- Partnering with Solutions Engineers and Business Development Reps to uncover needs, guide evaluations, and develop compelling demos and POCs
- Maintaining accurate forecasts and pipeline visibility with disciplined deal tracking
- Providing customer and market feedback to Product, Engineering, Marketing, and GTM leadership to shape product direction and sales motion
- Refining sales processes, qualification criteria, discovery frameworks, and best practices as the organization scales
- Contributing to a collaborative, high-accountability sales culture and mentoring new GTM team members
You'll have significant autonomy to shape how Antithesis sells, qualifies, forecasts, and grows its customer base. This role requires comfort with ambiguity and a willingness to operate without a fully defined playbook in an early-stage, rapidly evolving company.
REQUIREMENTS:
- 5+ years of B2B enterprise software sales experience, preferably selling developer tools, reliability, infrastructure, observability, cloud, testing, or other technically complex products with technical ICPs
- Proven experience selling to software engineering organizations and engaging technical buyers throughout the sales process
- Strong discovery and consultative selling skills; ability to uncover customer problems rather than simply present capabilities
- Track record of owning and closing complex enterprise opportunities with multiple stakeholders and meaningful technical evaluation requirements
- Experience creating pipeline through BDR partnership, outbound prospecting, field marketing, and/or strategic planning
- Ability to move comfortably between technical and business conversations, adapting messaging for engineers, engineering leaders, and executives
- Comfort operating in early-stage or rapidly evolving companies where processes, messaging, territories, and responsibilities are still being developed
- High degree of ownership, sound judgment, and willingness to take initiative without waiting for a fully defined playbook
- Strong written and verbal communication skills in English
- Willingness to travel for customer meetings, industry conferences, regional events, meetups, and team activities
NICE TO HAVE:
- Prior experience in Sales Engineering, Solutions Consulting, or similarly technical customer-facing roles
- Technical curiosity to understand how customers build, deploy, test, and operate software; ability to engage credibly with technical audiences
- Experience selling emerging or category-creating products where customer education and market development are part of the sales process
- Experience at early-stage startups where you helped establish or refine the sales motion
- Additional language skills beyond English
