Imagine a world where we’re not just reacting to the latest security headline, but quietly shaping the future threat landscape so our customers sleep better at night (and so do we). As a Principal Product Security Researcher at Chainguard, you’ll lead our product security research function end-to-end: mapping emerging threats, turning insight into strategy, and helping Chainguard stay several moves ahead of attackers across our entire product portfolio. The role, in a nutshell Chainguard prioritizes our customers’ security above all else, which means preparing not just for the attacks of today, but for those of tomorrow as well. In this Principal-level role, you’ll: Own the product security research agenda for Chainguard scanning the broader ecosystem, identifying emerging attack patterns, and translating them into clear risks and opportunities for Chainguard and our customers. Shape security direction across products and platforms, partnering closely with Product, Engineering, and Security leadership to embed your findings into roadmaps, architecture decisions, and long-term plans. Operate as someone who sees the whole ecosystem, spots issues early, and helps others navigate with confidence (and just enough healthy paranoia). If you enjoy turning ambiguous, fast-moving threat intel into concrete, multi-quarter plans that change how a company operates, this is your playground. What you’ll do: Research emerging threats & trends in software supply chain and product security, and analyze their impact on Chainguard’s products and customers. Design creative mitigations across people, process, and technology not just proof-of-concept demos, but pragmatic defenses that actually get adopted. Lead large-scale, multi-quarter initiatives that materially reduce risk or improve our security maturity across multiple product lines and platforms. Partner with executive and senior engineering leadership to drive org-level security strategy, influence key roadmap decisions, and secure buy-in for big, complex changes. Identify systematic weaknesses (in systems, structures, and sometimes habits) and develop plans that fix root causes in ways that persist long after you’ve moved on to the next hard problem. Mentor and uplevel others across Product Security and Engineering by helping teams think more strategically about threats, risk, and long-term security posture. Represent Chainguard externally through talks, conferences, and thought leadership, sharing what we’re learning and helping move the industry forward.

Have expert knowledge across multiple domains such as secure architecture, application/product security, software supply chain, and org-level risk management and you know how to balance security, velocity, and reliability. Are comfortable owning ambiguous, cross-functional problems and turning them into structured, prioritized initiatives that ship and stick. Have a proven ability to present complex ideas to executive stakeho
