We’re building automated guardrails and high-leverage tooling integrations to keep our business moving fast and safely. We are looking for a practical, execution-focused Security Engineer to manage the configuration, integration, and engineering lifecycle of our internal security tools.</p><p style="min-height:1.5em">This is a highly versatile engineering role for someone who loves to solve security problems with code and automation. You will act as the engineering engine room for the InfoSec team - collaborating closely with our SecOps, AppSec, Architecture, Security GRC and IT Systems leads to translate security requirements into working configurations, automated pipelines, and custom data integrations.</p><p style="min-height:1.5em">Whether it's writing Terraform to roll out a new edge security rule, stitching together SaaS APIs via Python to pull data into a centralised reporting app, or jumping into a web UI for some quick "click-ops" configuration, your focus is entirely on efficiency, posture improvement, and eliminating manual toil.</p><p style="min-height:1.5em"><br /><strong>What You’ll Be Doing</strong></p><ul style="min-height:1.5em"><li><p style="min-height:1.5em"><strong>Configuration as Code:</strong> Drive security configurations across our stack utilising a Terraform and GitOps workflow.</p></li><li><p style="min-height:1.5em"><strong>Tooling Optimisation:</strong> Get the most out of our InfoSec tooling through proactive setup, tuning, and configuration, ensuring we maximise our defensive utility and continuously improve our security posture.</p></li><li><p style="min-height:1.5em"><strong>Platform Integrations:</strong> Build and maintain high-leverage integrations between cloud providers, SaaS platforms, and our core security tooling - for example, engineering log pipelines into our SIEM or automating evidence feeds into our compliance platform.</p></li><li><p style="min-height:1.5em"><strong>Automation Engineering:</strong> Architect and deploy agentic workflows and lean automation scripts to eliminate manual toil, driving productivity and scalability for the InfoSec team.</p></li><li><p style="min-height:1.5em"><strong>Frictionless Control Implementation:</strong> Design and deploy practical guardrails, CASB, and data loss prevention (DLP) policies across network boundaries and collaboration tools – for example, Google Workspace. Your focus is on safeguarding data and enabling safe tooling usage without creating engineering bottlenecks.</p></li></ul><p style="min-height:1.5em"><br /><strong>What We’re Looking For</strong></p><ul style="min-height:1.5em"><li><p style="min-height:1.5em"><strong>Practical Engineering Capabilities:</strong> Solid hands-on experience using Python (or similar) to automate tasks, Terraform to manage infrastructure, connect APIs, and manage infrastructure state, balanced with the judgement to use UI configurations when code isn't viable.</p></li><li><p style="min-height:1.5em"><strong>Cloud &amp; Infrastructure Literacy:</strong> Proven experience configuring or hardening security controls within cloud (AWS/GCP) environments (e.g. IAM and network/identity boundaries) and handling data formats like JSON to parse logs.</p></li><li><p style="min-height:1.5em"><strong>AI-First Execution:</strong> Enthusiastic about actively leveraging advanced AI coding tools (such as Claude Code, Codex) to exponentially increase your engineering output, script generation, and delivery speed.</p></li><li><p style="min-height:1.5em"><strong>Pragmatic Security Mindset:</strong> A builder who views security as a business enabler. You focus on building practical defensive posture rather than filling out compliance checklists, with the instinct to identify actual systemic risk based on context.</p></li><li><p style="min-height:1.5em"><strong>Bias for Action:</strong> An execution-focused operator. When a security control drifts or a peer needs a detection mechanism, you write the script, open the PR, or modify the control to get it done.</p></li><li><p style="min-height:1.5em"><strong>Communication &amp; Collaboration:</strong> The ability to debate technical IAM architecture details with a Platform Engineer and seamlessly explain to non-technical risk stakeholders why a specific control change matters.<br /></p></li></ul><p style="min-height:1.5em"><strong>Interview Process</strong></p><ol style="min-height:1.5em"><li><p style="min-height:1.5em">TA Screening Call</p></li><li><p style="min-height:1.5em">Hiring Manager Call</p></li><li><p style="min-height:1.5em">Technical Interview</p></li><li><p style="min-height:1.5em">Culture Interview </p></li></ol><p style="min-height:1.5em"></p><h2>Life at Lendable</h2><ul style="min-height:1.5em"><li><p style="min-height:1.5em"><strong>Winning team: </strong>the opportunity to scale up one of the world’s most successful fintech companies</p></li><li><p style="min-height:1.5em"><strong>Flexible working: </strong>flexible approach tailored to each role.
