Senior Account Executive

Full Job Description

About Adaptive Security Adaptive is a cybersecurity startup on a mission to stop AI-powered cyberattacks. In December 2025, the company announced an $81M Series B led by NVIDIA and Bain Capital Ventures, with participation from Capital One Ventures, Citi Ventures, and continued support from Andreessen Horowitz (a16z), the OpenAI Startup Fund, and Abstract Ventures. The round marked NVIDIA’s first AI cybersecurity investment.

Adaptive was founded by Brian Long and Andrew Jones, repeat entrepreneurs who have built and scaled category-defining companies. Brian and Andrew previously co-founded Attentive, which grew to more than $500M in annual revenue and a $10B+ valuation, and TapCommerce, which was acquired by Twitter. Together, they bring deep experience building high-growth, product-led businesses at massive scale as Adaptive builds the security layer for the AI era.

Trusted by leading banks, technology companies, and healthcare organizations, Adaptive protects teams from emerging threats like deepfakes, smishing, and AI-powered voice scams. With rapid enterprise adoption and a $200B+ market ahead, the company is just getting started.

The Role We’re looking for a driven, high-performing Account Executive to join our GTM team, based out of our Sydney office. In this role, you’ll focus on landing large enterprise accounts across finance, healthcare, and technology.

You’ll be partnered with a dedicated BDR to support top-of-funnel pipeline generation and outbound efforts, enabling you to stay focused on progressing high-value opportunities, running tight sales cycles, and closing new logos.

This is a role designed for sellers who thrive on collaboration and momentum. You’ll spend time working side-by-side with leadership, marketing, product, and customer success—while also participating in company events, team offsites, and industry conferences that help shape both our culture and our go-to-market strategy. Day to day, you’ll be deeply involved in refining our sales motion, sharing feedback from the field, and helping build a repeatable enterprise engine from the ground up.

• Work closely with Product and Engineering to tailor demos and influence roadmap

• Provide real-time feedback on messaging, pricing, and competitive positioning

• Help build the playbooks, processes, and systems that will scale Adaptive’s GTM engine

Who You Are

• 3–7+ years of B2B SaaS sales experience, preferably in cybersecurity or a technical category

• Proven success closing 6- and 7-figure deals with large enterprise customers

• Comfortable running a consultative sales process with multiple stakeholders

• Resourceful, gritty, and highly self-motivated—you thrive in startup environments

• Exceptional communicator, both in person and in writing

• Must be located in Sydney, requiring ability to commute once we open our office

What We Offer

• High-impact role selling a product that resonates with real urgency

• Competitive comp with uncapped commission
