Job summary

United States Digital Space LLC in London is building its security operations capability from the ground up, designing detection and monitoring, deciding in-house versus outsourced work, and setting how alerts are handled and escalated.

You will lead incident response alongside our SRE and reliability teammates, build playbooks, practice drills, and drive continuous improvement in resilience and recovery across platforms.

Qualifications

• Experience building or leading security operations, or detection and response, ideally where you had to set it up rather than inherit it
• Strong grounding in detection and monitoring, including logging, alerting and building useful detections
• Experience leading incident response, including playbooks, exercises and learning from what happened
• A strongly collaborative approach, with real experience working alongside site reliability or platform engineering teams and sharing tooling where it makes sense
• Experience choosing and managing outsourced monitoring or response providers
• A practical, low‑drama approach that keeps things proportionate
• Willing to explore where AI can help in security monitoring and response, and pragmatic about applying it where it genuinely fits the use case

Responsibilities

• Set up detection and monitoring for security across the platform and wider IT, including the tooling, dashboards and log sources needed to investigate quickly
• Decide how much we run ourselves and where we use outsourced monitoring or response, and own that relationship
• Set up how security alerts are handled, owned and escalated, starting with working-hours coverage
• Lead how we respond to security incidents, including playbooks for the most likely scenarios, a single place of record, and regular practice exercises
• Work with the reliability team on resilience and recovery, including backups, restore testing and disaster‑recovery exercises
• Triage vulnerabilities found in our running systems and infrastructure into a shared tracker
• Run exercises that test and improve our defences over time
