About Adaptive

NVIDIA and OpenAI's only AI cybersecurity investment.

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.

Role

We are seeking a Software Engineer with a passion for developing high-quality software in a high-growth startup environment where every engineer has outsized impact on the product and company.

You will ship real features to real customers from day one, building products that define AI cybersecurity. As you grow here, you'll develop deep technical judgment and your own perspective on where the product should go.

Responsibilities

• Build and ship features across the full stack - frontend, backend, and infrastructure.
• Write clean, tested code that other engineers can understand and build on.
• Work side-by-side with product and design - roles blur here, and engineers have influence on what we build and why.
• Develop your own perspective on the product by engaging directly with customer feedback.
• Continuously improve your craft - we invest heavily in tooling, including AI coding assistants.

Qualifications

• 1-4+ years of experience building customer-facing software.
• Bachelor's degree or equivalent experience in Computer Science, Software Engineering, or a related field.
• Strong development experience with modern, strongly-typed programming languages such as Java, C#, TypeScript, or Go.
• Proficient with SQL databases and relational schema design.
• Familiarity with frameworks such as Spring Boot and React/Redux is a plus.
• Experience deploying software in distributed environments (AWS, GCP, Azure).
• A full-stack, can-learn mindset - willing to work outside your comfort zone across frontend, backend, and infrastructure.
• Strong problem-solving skills and the humility to seek, receive, and incorporate feedback.

What We Offer

• An opportunity to work on a challenging product that will impact millions of people
• A culture that promotes continuous learning and growth, with access to resources and mentorship to advance your skills and career.
• A supportive, inclusive environment where every team member's contribution is valued.

Compensation & Benefits:

• Competitive cash compensation and meaningful stock.
• Several medical plans to choose from, most covered at 100% by Adaptive.
• 401k through Vestwell.
• Unlimited PTO, including winter break from Dec 24 - Jan 1.
• A fantastic office atmosphere including coffee, espresso, lounge, snacks, whiteboards, and tons of conference space.
• Rotating choice of 4 free lunch options from local restaurants every day.
• Expense dinner if you're in the office past 7pm. Expense Uber if you happen to stay past 9pm.
