About Tessell

Tessell is redefining enterprise data infrastructure with an AI-native, multi-cloud Database-as-a-Service (DBaaS) platform designed for both transactional and analytical workloads. Our platform simplifies and automates the complete database lifecycle, enabling organizations to securely manage, scale, and optimize data across cloud environments. As we continue to innovate at the intersection of cloud, data, and AI, security remains a foundational pillar of everything we build.

Role Overview

We are looking for a highly skilled AI Security Researcher to join our Security team and help shape the future of secure cloud and AI-native data platforms. In this role, you will conduct advanced security research to identify emerging threats, uncover novel attack vectors, and drive the development of security capabilities that protect modern cloud-native and AI-powered environments.

SUMMARY

We're looking for a talented AI Security Researcher to join our team and play a critical role at Tessell, risk-driven approach to cloud security. This role requires deep technical research into complex cloud- and AI-native environments to identify the most significant, unaddressed risks.

WHAT YOU'LL DO

• Conduct deep technical research to discover and report novel risks and attack vectors specific to modern cloud and AI-native architectures and systems. 
• Discover and articulate the highest unaddressed risk areas, working with Product and Engineering teams to translate research into product capabilities.
• Define necessary foundational product capabilities by delivering both compelling proofs of risk (demonstrating impact) and technical POCs (showing how to solve it).
• Work closely with Product and Engineering teams to ensure comprehensive risk coverage and support the investigation of new and complex product scope.

WHAT YOU'LL BRING

• 8+ years of hands-on experience in security or security research, specifically relevant to modern cloud environments (AWS, GCP, Azure, Kubernetes, etc.).
• Strong hands-on skills with scripting languages (e.g., Python, Go) for automation and research, as well as query languages (e.g., KQL, SQL) for efficient data analysis of security telemetry. 
• Proven ability to work independently, prioritize effectively, and drive complex, multi-quarter research projects from initial concept through to clear, delivered impact.
• Excellent written and verbal communication skills, with a track record of successfully collaborating with cross-functional teams (e.g Product, Engineering, Marketing) to achieve shared goals.

ADVANTAGE

• Specialized knowledge or research experience in cloud security, focusing on risks to AI as deployed in the enterprise. 
• Experience in public-facing work, such as presenting at recognized industry conferences, authoring technical blog posts, or publishing research.
• Experience conducting data-driven research and working with large-scale security telemetry to derive statistically significant or high-impact findings.

Why Join Tessell?

• Work on cutting-edge cloud, database, and AI technologies.

• Influence the security strategy of a rapidly growing enterprise data platform.

• Collaborate with world-class engineers, architects, and security professionals.

• Solve complex security challenges at the intersection of AI, cloud infrastructure, and data management.

• Make a direct impact on the security and trust of next-generation data platforms.
