Senior Security Engineer- USA

About The Role Hopper's Security team is small by design and consequential by impact—this role sits at the centre. As a Senior Security Engineer, you will own the tooling, automation, and processes that keep our applications secure across their entire lifecycle, building systems that make security invisible to developers and unavoidable by default. It is a builder’s role: write code, ship tools, and use AI as a core component of your workflow. Day‑to‑Day Responsibilities Own and evolve the vulnerability management program with a focus on application security—container images, dependencies, code scanning, and runtime detection. Build and maintain security tooling that integrates directly into CI/CD pipelines and developer workflows, so security happens automatically rather than as a gate. Use AI extensively to write code faster, automate analyses that would otherwise require manual review, and build intelligent tooling that scales beyond what a small team could achieve manually. Assess and improve how we leverage available telemetry across our systems. Work directly with engineering teams to influence secure development practices—shipping tools and defaults that make the secure path the easy path. Investigate and respond to security findings when needed, but spend more time building systems that prevent and detect issues than chasing them manually. Adapt quickly as priorities shift; the team is agile and tomorrow’s challenge may look different from today’s. Desired Qualifications At least 5 years of experience in software and/or platform engineering, with the ability to design, build, and maintain production‑quality tools. Deep experience in application security and vulnerability management—understanding CVEs, dependency risks, container security, and SDLC integration, and holding informed opinions on what to fix versus noise. Hands‑on experience with cloud infrastructure, ideally GCP/GKE or equivalent, and the ability to adapt to our stack. A demonstrated habit of using AI tools—coding assistants, LLMs—as a core part of how you build and analyse, not an occasional shortcut. A bias toward automation—when you see a repetitive manual task, your instinct is to write a tool, not a runbook. Comfort with ambiguity and ownership—often the only person on a problem, making judgment calls on priority, approach, and scope without waiting for direction. Experience influencing engineering culture around security, making developers care without slowing them down. Strong written and verbal communication skills, including explaining our security posture clearly to customers when needed.
