We are unable to sponsor or take over sponsorship of an employment visa at this time. Mark43's mission is to empower communities and their governments with new technologies that improve the safety and quality of life for all. We build powerful, scalable, and elegant software that sets a new standard for the tools upon which first responders rely. Our users are diverse, and we are committed to embracing diversity of thought and experience within our team. We are looking for a AWS Cloud Security Operations Engineer to join our team in Manchester. You will own vulnerability and threat management for an environment where the stakes are real — the software you help protect supports law enforcement and emergency services across the US and UK. This is a hands-on, execution-focused role: you will run a serious security program, respond to real incidents, and be the on-the-ground security presence in our Manchester office, working closely with a wider Cybersecurity team based in the US. What You'll Do If you were part of our team, here are some things you would have done last week: Driven our vulnerability management program end to end: running scans across cloud infrastructure, networks, and applications, prioritizing findings by risk, and tracking remediation through to closure. Researched emerging threats relevant to our environment, turning threat intelligence into clear, actionable guidance on what to patch, watch, or harden next. Led the response to a security alert: triaging it, containing the issue, coordinating with the wider Cybersecurity team, and writing up the post-incident review so we are stronger next time. Reviewed cloud security configurations across our AWS environment, identifying misconfigurations and hardening controls in line with security best practices. Supported colleagues in the Manchester office with day-to-day IT needs — account access, hardware, new starter setup — as the on-site technical presence. Taken your turn on the on-call rota, ready to respond when a critical security incident does not keep office hours. What You'll Need We are looking for a cybersecurity professional with a minimum of 5 years of experience, with a strong focus on vulnerability management, threat research, and cloud security. You have the judgement that comes from time in the field: you know which vulnerabilities to escalate, how to run an incident calmly under pressure, and when to ask for help. Experience with cloud environments — particularly AWS — and familiarity with vulnerability scanners, endpoint protection, and SIEM tooling are important. An awareness of UK data protection requirements and frameworks such as Cyber Essentials or ISO 27001 is a plus. Solid general IT support skills across Windows environments and networking matter too, since you will be the on-site technical resource in Manchester. You should be comfortable on an on-call rota and collaborating across time zones. Security Clearance Given the sensitive nature of the work we do and the law enforcement agencies we serve, the successful candidate will be required to obtain and maintain NPPV3 and SC (Security Check) clearance. We will support you through the process, but please note that an offer is conditional upon successfully obtaining the required clearances. This typically requires a minimum of 5 years' recent UK residency — please raise eligibility questions with us during the process. Who Thrives Here Hands-on and execution-focused. You are more comfortable running a vulnerability program than writing a policy about one. You get things done. Calm and decisive under pressure. When an incident hits, you hold steady, work the problem methodically, and make sensible calls with imperfect information. Self-directed and dependable. As the senior security presence in the Manchester office, you take ownership without waiting to be told and follow through so colleagues can trust that things are handled. A clear communicator. You can explain a security risk to a senior leader and help a colleague with an access issue in the same afternoon, adjusting how you communicate to whoever is in front of you. Location & Logistics This role is based in our Manchester office, on-site 3 days per week. Compensation We are offering £60,000–£80,000 per year depending on experience, plus Mark43's benefits package including private medical insurance, pension contributions, and equity participation.
