Senior Security Engineer (Europe/Americas) in London

Mimica's mission is to empower enterprises, teams, and individuals to reclaim their most precious resource time and work more efficiently, with greater purpose and impact. Mimica's AI-powered task mining observes employee actions across the desktop and categorises them into detailed process maps.

We’re a fast-growing scale-up building up our security program from the ground up. As the new member of the InfoSec team, you’ll own critical security initiatives end-to-end, working side-by-side with engineers to harden our cloud-native SaaS platform and significantly raise our overall security posture. This is a high-impact, high-autonomy role perfect for a self-starter who enjoys building and deploying scalable security processes in a scale-up environment.

What You’ll Do Day-to-Day

• Lead the build-out and operation of core security capabilities: vulnerability management, patching, SIEM/logging, cloud security monitoring, and alert triage.
• Deploy, configure, and tune security tooling (scanners, WAFs, CSPM, SIEM, endpoint protection).
• Partner with engineering to build security with developer experience in mind.
• Triage and assess vulnerabilities, drive remediation prioritisation, and reduce risk in a pragmatic yet rigorous way.
• Design and implement tactical incident-response playbooks and improve detection coverage.
• Periodically review major architectural changes and guide engineering on secure design trade-offs.
• Continuously improve processes so security scales as the company grows.

Who We’re Looking For

• Senior-level experience (typically 5+ years) in security engineering or SecOps, with a strong preference for hands-on roles in startup or scale-up environments.
• Proven ability to independently deploy and manage cloud security solutions, especially in GCP (big plus), AWS, or Azure.
• Deep expertise in one or ideally several of the following: vulnerability management programs, cloud-native SIEM/logging, CSPM/CNAPP tools, IaC security, secure SDLC integration, and incident response.
• You are mindful of developer experience as part of the process.
• Strong communication skills; you can explain complex risks or trade-offs clearly to both technical and non-technical audiences.

Nice to Have

• OSCP, CISSP, or similar offensive/security certifications;
• Experience preparing for SOC 2, ISO 27001, or FedRAMP.

Location

This is a fully remote position. You can be based anywhere in the UK, Americas, or Western Europe within a UTC-6 to UTC+1 timezone.
