Who We Are
Pindrop is a cybersecurity company delivering continuous identity verification across voice, video, and digital interactions. Powered by the Pindrop Intelligence Network, our unified trust platform helps enterprises answer three critical questions:
Is this identity synthetic? Detect AI-generated and manipulated voice and video.
Is this identity risky? Identify fraud, suspicious behavior, and other risk signals.
Is this identity known? Authenticate identities using voice, device, behavioral, and other signals.
Pindrop brings this intelligence together across purpose-built trust engines to help organizations make informed decisions in real time — protecting customers, workforce interactions, and emerging AI-driven interactions.
Pindrop protects billions of high-risk interactions for enterprises, including leading financial institutions, insurers, and healthcare organizations. Its technology is informed by more than 8 billion real-world interactions annually and protected by 300+ patents.
Recognized by TIME as one of the 10 Most Influential Software Companies of 2026 and by Inc. for Best in Business for Innovation, Pindrop is backed by leading investors including Andreessen Horowitz, IVP, and CapitalG.
What you’ll do
As a Senior Security Researcher (Red Team), you will help Pindrop proactively identify and exploit weaknesses across product, cloud, and AI-powered systems so we can strengthen defenses before adversaries do. This role blends hands-on offensive security, GenAI attack simulation, security engineering, and operational partnership with blue-team, product, and AI/ML stakeholders.
Design and execute red team operations against Pindrop’s GenAI systems, LLM pipelines, RAG architectures, autonomous agents, APIs, SaaS products, and cloud environments, simulating real-world attacks across both traditional and AI-specific attack surfaces.
Conduct adversarial testing focused on prompt injection, indirect prompt attacks, jailbreaking, model extraction, training-data poisoning, data leakage, inference abuse, and unauthorized output manipulation.
Use deepfake generation, voice synthesis, and related spoofing techniques to test and attempt to defeat Pindrop’s voice authentication and deepfake detection capabilities, helping identify model robustness and detection gaps.
Develop novel attack chains that combine GenAI vulnerabilities with infrastructure, application, identity, and API weaknesses to create realistic end-to-end threat scenarios.
Plan and execute full-scope penetration tests and support bug bounty efforts across Pindrop’s web applications, APIs, SaaS products, and AWS/GCP environments using commercial and open-source offensive tooling.
Perform architecture reviews, security code reviews, and threat modeling with emphasis on vulnerabilities introduced by AI/ML components, model integrations, and LLM-facing services.
Build automation for offensive security workflows, testing, compliance checks, alerting, and reporting using Python or similar scripting languages, including AI-native attack tooling where useful.
Partner closely with SecOps and security engineering to improve detections, tune response workflows, and translate red team findings into practical remediation and defensive improvements.
Stay current on GenAI security research, adversarial ML techniques, evolving threat intelligence, and relevant regulatory developments, then apply those insights to Pindrop’s security program.
Who you are
You are an adversarial thinker who approaches security from an attacker’s perspective and brings the creativity, rigor, and curiosity to prove it.
You have genuine hands-on experience attacking AI systems, not just reading about them, and you enjoy breaking assumptions that others consider safe.
You continuously look for automation and AI-powered efficiencies in offensive security workflows.
You communicate clearly and can translate technical findings into prioritized, actionable guidance for technical and executive audiences alike.
You work independently and thrive in ambiguous, fast-moving environments with minimal supervision.
You are resilient, optimistic, accountable, and adaptable when priorities shift.
Your skill-set
Must-haves
3+ years of hands-on penetration testing and red team experience across SaaS applications, cloud infrastructure, APIs, and web applications.
Demonstrable experience attacking GenAI or LLM-based systems, including prompt injection, jailbreaking, indirect prompt attacks, model extraction, or adversarial input generation.
Hands-on experience with deepfake tools, voice synthesis, or audio/visual spoofing technologies in an offensive or research context.
Strong proficiency with offensive security tooling such as Burp Suite, OWASP ZAP, Nmap, Metasploit, Cobalt Strike, or equivalent frameworks.
Experience configuring and operating SAST and DAST tools and integrating them into CI/CD pipelines.
Proficiency in at least one scripting or programming language, with Python strongly preferred, for custom attack tooling and workflow automation.
Familiarity with AI-specialized security tools or frameworks such as Garak, PyRIT, Claude Security, or similar adversarial ML tooling.
Strong understanding of cloud security architecture, container security, API security, and common security standards including ISO 27001/27002, NIST, CIS, PCI DSS, OWASP, and SOC 2.
Nice-to-haves
Prior software development or secure architecture experience, including the ability to reason about production code across multiple languages.
Research, publication, or deep practitioner background in adversarial machine learning, LLM security, or voice/audio deepfake detection.
Relevant certifications such as OSCP, GPEN, GWAPT, GXPN, CEH, or equivalent.
Prior experience in voice biometrics, AI security, fraud prevention, or similarly high-risk product environments.
What’s in it for you
As a Pindropper, you’ll join a rapidly growing company making technology more human with the power of voice. You’ll help shape how Pindrop attacks and defends modern AI-enabled systems, working at the intersection of offensive security, GenAI, deepfake defense, and cloud security. Your work will have direct impact on how we protect voice identity and high-trust customer interactions. You’ll work alongside a passionate, high-performing team committed to excellence and enjoying the journey together.
What We Offer
As part of Pindrop, you’ll directly influence our products and contribute to shaping the future of voice security. We invest in great people and support them with great benefits:
Competitive compensation, including equity for all employees
Unlimited Paid Time Off (PTO)
