Location: Tallinn, Estonia Entity: Monese Estonian entity, supporting both Monese and Pockit Team: Security Reports to: Head of Security Level: Mid-level, 3 to 5 years of relevant experience Employment type: Full time, permanent About Pockit and Monese Pockit and Monese are all-in-one money apps that make it easier for people to access and manage the financial tools they need to take control of their money. We provide vital financial services, from accounts and cards to income advance solutions. In October 2024, Pockit acquired Monese, bringing together two complementary businesses and creating a leading fintech company focused on serving people who are underserved by traditional banks. Together, we serve more than three million customers across the UK and Europe. We're a diverse, international and energetic team, with colleagues based across London, Newcastle, Tallinn and remote teams across Central Europe. We value curiosity, ambition, accountability and resilience, and we want everyone to feel at home, have a voice and know that their contribution matters. We give people the trust and space to take ownership, share ideas, influence decisions, and make a real impact on our customers and our business. The role We are hiring a Security Engineer who will be part of the Security Team. This is not a policy-writing desk job and it is not a pure infrastructure role. You will implement and operate the technical controls that our regulatory obligations demand, prove those controls work with real evidence, and help engineering teams build in a way that keeps us compliant by default. The job splits roughly three ways: finding and fixing vulnerabilities with our engineering teams, hardening our cloud and access controls, and turning DORA, PCI DSS, ISO 27001, FCA and GDPR requirements into controls that actually work rather than documents that merely exist. What you will do - Find the vulnerabilities. Run scanning across cloud, endpoints, containers, code and dependencies, cut through the noise, and prioritise by real exploitability rather than raw CVSS score. - Get them fixed. Work directly with engineering teams to agree fixes and dates, track remediation SLAs, chase what slips, and provide reporting and visibility.. - Harden the platform. Improve our AWS security posture, close misconfigurations, put guardrails into infrastructure as code, and keep secrets and pipelines secure. - Own access. Run identity and access governance end to end: joiners, movers and leavers, SSO and SCIM coverage, privileged access and periodic reviews. - Make compliance real. Implement and evidence the controls behind DORA, PCI DSS, ISO 27001, FCA expectations and UK/EU GDPR, and automate the evidence so audits are a query rather than a fire drill. - Support detection and response. Work with our managed detection and response provider on alert quality and escalation, and play your part in incidents and the reviews that follow. - Tune log sources and detection rules, write new detection use cases, and keep alert quality high enough that what reaches us is worth looking at. - Assess third parties. Run security due diligence on vendors, keep the ICT and supplier access register current, and handle inbound security questionnaires. What you will bring - 3-5 years in security engineering, security operations or technical security, ideally with some exposure to fintech, payments or another regulated environment. - Hands-on vulnerability management: running the tools, triaging the output, and persuading engineers to ship the fix. - Practical cloud security experience, ideally AWS: IAM, networking, logging, encryption, and the misconfigurations that keep coming back. - Identity and access management in practice: SSO, SCIM provisioning, role design and access reviews. - Scripting and automation (Python, Bash or similar) to query APIs, gather evidence and remove manual toil. - Working familiarity with at least one of DORA, PCI DSS, ISO 27001, NIS2 or SOC 2, and the appetite to get fluent in the rest. - The ability to explain the same technical risk to an auditor and to a software engineer without changing the facts. - Hands-on SIEM and SOC experience: working with log sources, writing or tuning detection rules, triaging alerts, and running incidents through to resolution. Why Join Us? - Make a real difference: Work at the intersection of technology and financial inclusion, helping people take greater control of their money. - Have a voice: Your ideas and perspective matter. You'll have the opportunity to influence decisions, take ownership and shape how we work. - Make an impact: Work on initiatives that reach millions of customers across the UK and Europe. - Work with great people: Join a diverse, international and ambitious team where collaboration and curiosity are encouraged. - Grow with us: Be part of a fast-moving fintech where you'll have plenty of opportunities to learn, develop and make your mark.
