The role You will be the architect and guardian of the infrastructure where our customer data lives and our web applications operate. As our Platform Lead, you will spearhead our foundational engineering efforts while embedding security deeply into our engineering culture. You will focus on building scalable infrastructure, identifying vulnerabilities, securing our cloud perimeter and ensuring that our code and environments meet the highest security standards before they reach production. Beyond identifying risks, you'll build the automated guardrails and internal developer platforms that allow our engineering teams to move fast without breaking things. By architecting and securing our AWS environments, fortifying our edge network and driving DevSecOps practices, your work will directly enable developer velocity, protect our customers' financial data and ensure the resilient operation of a modern lending platform. This is a hands-on, 'player-coach' role. While you will guide the strategic direction of our platform and security posture, you will remain deeply technical - engineering secure-by-default infrastructure, integrating security tooling directly into our CI/CD pipelines, remediating complex vulnerabilities and leading from the trenches by example. What You’ll Do Lead platform engineering and cloud security: Proactively design scalable AWS architectures and author secure-by-default Infrastructure as Code (Terraform).Identifying, introducing, and improving security controls across Bridgit’s, engineering, and cloud infrastructure disciplines.Leading threat modelling code review exercises for new and complex architectures and features.Defend the perimeter: Configure and actively manage our edge network defenses, including Web Application Firewalls (WAF), DDoS mitigation and API security.Automate security: Optimise and maintain robust CI/CD pipelines, directly embedding and managing automated application security testing.Drive remediation: Own infrastructure reliability and continuous vulnerability management across our cloud-native stack (containers and serverless).Guide architecture: Act as the core subject matter expert during system design reviews, ensuring high availability and alignment with fintech data protection standards.Champion a "shift-left" culture: Remain deeply hands-on while mentoring developers and DevOps engineers on secure coding, robust system design and cloud security fundamentals. Essential Experience What we are looking for 6+ years of experience in Platform Engineering, Cloud Infrastructure, or DevSecOps, preferably within a regulated fintech or high-growth tech environment.Player-Coach mentality: Demonstrated leadership capabilities combined with a strong desire to remain in a highly hands-on, technical capacity.Deep technical proficiency with industry-standard infrastructure and security tooling, specifically AWS, Terraform, CI/CD platforms (e.g., GitHub Actions) and SAST/DAST/SCA integrations.Cloud-native expertise: A strong understanding of modern architectures, encompassing the performance, reliability and security of containers (Docker/Kubernetes) and serverless environments.Edge security track record: Proven experience managing edge platforms (Cloudflare highly preferred), including WAF rule tuning and bot management.Compliance familiarity: Working knowledge of auditability standards relevant to financial services (e.g., SOC 2, ISO 27001, PCI-DSS).Collaborative communicator: The ability to clearly deconstruct complex architectural risks to cross-functional teams, favoring building "paved roads" and secure defaults over acting as a gatekeeper.
