About the Role

As our Security Engineer, you will own security at nsave end-to-end — from cloud infrastructure hardening to driving us through formal compliance certifications. Working closely with the CTO, you will be the person who ensures that the trust our customers place in us is backed by world-class security practice. This is a foundational role: you'll set the bar for how we build, operate, and certify a regulated fintech platform at scale.

Who You Are

• Security engineer, not just an auditor: You can write policy and pass an audit, but you’re equally comfortable getting hands-on in the infrastructure, identifying gaps, and fixing them.
• Fintech or regulated-industry background: You have worked in fintech, banking, or payments — ideally in a regulated environment — and understand the unique risk, data privacy, and compliance obligations that come with it.
• Clear communicator: You can translate technical risk into plain language for non-technical stakeholders, leadership, and external auditors.
• Proactive and ownership-driven: You don’t wait to be told where the risks are — you go looking for them.
  
  

Must Have

• AWS Organizations design: Hands-on experience designing and building an AWS Organization from the ground up — multi-account structure, Organisational Units, Service Control Policies, and least-privilege IAM across every account.
• Cloud network security: Deep experience securing cloud networks — VPC design and segmentation, security groups and NACLs, private connectivity, and WAF / DDoS protection.
• Infrastructure as code: Strong hands-on Terraform experience — you define infrastructure and security controls as code, and build guardrails into CI/CD so the secure path is the default one.
• Endpoint security: Experience securing endpoints across a remote team — EDR, device management (MDM), hardening baselines, patching, and disk encryption.
  

Nice to Have

• Security operations (SOC): Experience setting up or working in a Security Operations Centre — SIEM, log monitoring, alerting, threat detection, and incident response.
• Compliance certifications: Experience taking a company through PCI DSS, SOC 2, or ISO 27001 — designing controls, gathering evidence, and working with auditors.
  

How You'll Make a Difference

• Own our security posture: Define, implement, and continuously improve nsave’s information security programme across infrastructure, application, and operational layers.
• Lead compliance certifications: Drive nsave through relevant security certifications (PCI DSS, SOC 2, ISO 27001), owning the end-to-end process from gap analysis through to audit and accreditation.
• Harden our cloud environment: Design and secure our AWS Organization and account structure — enforcing least-privilege access, securing our cloud network, and managing it all as code in Terraform. (rewritten)
• Secure our endpoints: Own endpoint security across our remote team — device management, EDR, and hardening standards for every laptop that touches production. (new)
• Embed security into engineering: Partner with backend and platform engineers to build security into our SDLC — code reviews, threat modelling, secrets management, dependency scanning, and CI/CD pipeline security.
• Manage risk and incidents: Maintain our risk register, lead incident response when needed, and conduct post-mortems that drive lasting improvements.
• Vendor and third-party security: Assess the security posture of third-party tools and partners, ensuring our supply chain meets the standards expected of a regulated financial platform.
• Build a security-first culture: Run internal training, champion secure-by-default practices, and make security something the whole team owns.
