Senior Engineering Manager, Security

We are a fast-growing FinTech company looking for a talented and enthusiastic engineer to join our team. We are expanding, making this a perfect position if you would like to have a significant impact on our company’s growth and develop your role and career as the business evolves. You will join a team where your ideas will be welcomed and valued. This is a senior individual contributor and leadership role. You will report to the CTO, with a functional dotted line to the Head of Compliance. You will work closely with engineering, compliance, and risk functions, and represent security at board level. You will be the architect of a security culture that is rigorous, pragmatic, and commercially aware. The role will be hands on at the outset. Role responsibilities Security strategy & governance: Own the information security strategy, aligned to FCA requirements, ISO 27001, and the firm’s risk appetite. Chair the Information Security Working Group; prepare materials for the board and Insignis Risk Committee. Lead the ISO 27001 programme, including ongoing audit readiness and continual improvement. Maintain and evolve the ISMS, risk register, and security policy suite. Represent security in regulatory engagements, including FCA supervisory requests and third-party due diligence. Technical security & architecture: Define and enforce the security architecture across our Azure-native, Kubernetes-based platform. Govern security controls across the full stack: Kafka, .NET/C#, Vue.js, Kong API Gateway, Auth0, and Salesforce. Lead threat modelling, penetration testing, and vulnerability management programmes. Own identity and access management strategy, including Entra ID, Auth0, and partner federation. Drive security engineering best practices within product and platform teams. Build and govern security for AI and machine-learning systems — covering model and data governance, defences against prompt injection and model abuse, and safe adoption of generative-AI tooling across the business. Lead the firm's quantum-safe transition to post-quantum cryptography — maintaining a cryptographic inventory, assessing exposure, and planning a crypto-agile migration to NIST-standardised PQC algorithms. Compliance & regulatory: Ensure security controls meet FCA SYSC obligations, SYSC 15A operational risk requirements and ISO27001 standard. Work closely with the Head of Compliance on regulatory horizon scanning, security-related policy obligations, and audit responses. Partner with the DPO on data governance and breach notification obligations. Manage third-party and supply chain security risk, including critical outsourcing oversight. Incident management & operations: Own the security incident response plan; lead major incident management for cyber events. Operate and improve security monitoring, SIEM, and alerting across the Azure estate. Run the security awareness and training programme for all ~180 staff. Manage relationships with external SOC, MSSP, and specialist security partners. Requirements Essential: Demonstrable experience leading information security in a regulated financial services or fintech environment. Strong working knowledge of FCA regulatory requirements (SYSC, operational resilience). Hands-on familiarity with cloud-native security on Azure (Entra ID, Defender, Sentinel, Key Vault, Policy). Proven delivery of ISO 27001 certification or equivalent ISMS framework. Ability to translate technical risk into board-level narrative clearly and credibly. Experience partnering with engineering teams — you are comfortable in a technical conversation and a risk committee meeting. CISM, CISSP, or equivalent professional qualification (or demonstrable equivalent experience). Desirable: Familiarity with API security patterns (Kong, OAuth 2.0, OIDC) and modern identity architectures. Background in or strong exposure to software engineering — understanding of SDLC security, threat modelling, and DevSecOps. Experience managing a security team and developing talent toward senior positions. Familiarity with Kafka-backed event architectures and the security considerations they introduce. Awareness of AI and machine-learning security risks and emerging AI governance frameworks (e.g. NIST AI RMF, ISO/IEC 42001). Understanding of post-quantum cryptography and quantum-safe migration and crypto-agility planning. Benefits 25 days holiday (exc.
