Senior Security Engineer

This is a fully remote position, open to applicants in United Kingdom.

📋 Description

• Take ownership of and enhance our vulnerability management program with an emphasis on application security — including container images, dependencies, code scanning, and runtime detection.

• Develop and maintain security tools that seamlessly integrate into CI/CD pipelines and developer workflows, ensuring that security is automated rather than acting as a barrier.

• Leverage AI extensively to accelerate coding, automate analyses that typically require manual review, and create intelligent tools that scale beyond the capabilities of a small team.

• Evaluate and enhance how we utilize available telemetry across our systems.

• Collaborate directly with engineering teams to promote secure development practices — not by drafting standards and documentation, but by delivering tools and defaults that facilitate a secure approach as the easiest option.

• Investigate and address security issues as necessary, but prioritize building systems that proactively prevent and detect problems over manually pursuing them.

• Quickly adapt to shifting priorities — our team operates with agility, and tomorrow's challenges may differ from today's.

⛳️ Requirements

• A minimum of 5 years of experience in software and/or platform engineering, with the capability to design, build, and sustain production-quality tools.

• Extensive experience in application security and vulnerability management — you are familiar with CVEs, dependency risks, container security, and SDLC integration, and you can articulate what requires attention and what does not.

• Practical experience with cloud infrastructure, preferably GCP/GKE or an equivalent, along with the flexibility to adapt to our technology stack.

• A proven track record of utilizing AI tools — such as coding assistants and LLMs — as an integral part of your development and analysis processes, rather than as a mere occasional shortcut.

• An inclination towards automation — when faced with a repetitive manual task, your instinct is to develop a tool rather than create a runbook.

• Comfort with ambiguity and a sense of ownership — you will frequently be the sole individual addressing a problem, requiring you to make judgment calls on priorities, approaches, and scope without awaiting direction.

• Experience in influencing engineering culture regarding security, with the ability to engage developers without hindering their progress.

• Excellent written and verbal communication skills, including the capacity to clearly convey our security posture to customers when necessary.

🏝️ Benefits

• Inquire about our very generous parental leave, which exceeds industry standards!

• Access to on-demand co-working spaces via FlexDesk and a work-from-home stipend.

• Carrot Cash travel stipend.

• Unlimited paid time off (PTO).

• An entrepreneurial culture where pushing boundaries and taking risks is part of daily operations.

• Open communication with management and company leadership.

• Small, dynamic teams that lead to substantial impact.
