About Lendable
Lendable is on a mission to build the world's best technology to help people get credit and save money. We are a growing fintech company, profitable since 2017 and backed by top investors including Balderton Capital and Goldman Sachs.
About the Role
We are looking for a practical, execution-focused Security Engineer to manage the configuration, integration, and engineering lifecycle of our internal security tools. This role is highly versatile and focuses on solving security problems with code and automation. The engineer will act as the engineering engine room for the InfoSec team, collaborating closely with various security and IT leads to translate security requirements into working configurations, automated pipelines, and custom data integrations.
What You’ll Be Doing
- Configuration as Code: Drive security configurations across our stack utilising a Terraform and GitOps workflow.
- Tooling Optimisation: 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.
- Platform Integrations: 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.
- Automation Engineering: Architect and deploy agentic workflows and lean automation scripts to eliminate manual toil, driving productivity and scalability for the InfoSec team.
- Frictionless Control Implementation: Design and deploy practical guardrails, CASB and DLP policies across network boundaries and collaboration tools – for example, Google Workspace, safeguarding data and enabling safe tooling usage without creating engineering bottlenecks.
What We’re Looking For
- Practical Engineering Capabilities: Solid experience using Python (or similar) to automate tasks, Terraform to manage infrastructure, connect APIs and manage infra state, with judgement to use UI configurations when code isn’t viable.
- Cloud & Infrastructure Literacy: Proven experience configuring or hardening security controls within cloud (AWS/GCP) environments such as IAM and network/identity boundaries, and handling data formats like JSON to parse logs.
- AI‑First Execution: Enthusiastic about actively leveraging advanced AI coding tools (such as Claude Code, Codex) to increase engineering output, script generation and delivery speed.
- Pragmatic Security Mindset: A builder who views security as a business enabler, focusing on practical defensive posture rather than compliance checklists and identifying systemic risk based on context.
- Bias for Action: An execution‑focused operator who writes scripts, opens PRs or modifies controls to get tasks done when a security control drifts or a detection mechanism is needed.
- Communication & Collaboration: Ability to debate technical IAM architecture details with a Platform Engineer and explain to non‑technical stakeholders why a control change matters.
