About the role:

The Platform Security Engineer is a valued member of our engineering team. We value evidence-backed opinions and offer the opportunity to play an integral part in shaping engineering rhythm, culture, and processes across planning, architecture and design, coding, deployment, and support.

In an ever-changing environment, Lendi Group is leading the charge in developing industry-first technology designed to offer Australian homeowners transparency, simplicity, and convenience in their home loan experience.
The Platform Security Engineer partners with engineering teams to evaluate planned changes, minimise security risk, and continuously improve our security posture. A key focus of the role is driving vulnerability and security findings down over time, improving security standards, and embedding secure-by-default practices across both traditional and AI-enabled systems.

Please note: this role will be a 12 Month Fixed Term Contract

• Working closely with the Cyber Security team to ensure security principles are consistently applied across the engineering environment.
• Collaborating and coding with engineering teams to uplift secure development practices and reduce recurring security findings.
• Designing, building, and maintaining secure cloud and microservice solutions.
• Improving security posture through effective use of COTS products, platform controls, and network infrastructure.
• Vulnerability and Threat Management — monitoring and assessing assets including cloud infrastructure, containers, packages, APIs, and requests, with a focus on remediation and measurable risk reduction.
• Supporting the secure design and operation of AI-enabled systems, including LLM integrations, automation agents, and MCP-based architectures.
• Implementing and reviewing AI security guardrails such as access controls, data protection, prompt-injection mitigation, and output validation.

• Build or integrate services to improve security and compliance

The ideal candidate is passionate about promoting a security-first culture and has a strong, current understanding of security best practices, with particular focus on cloud security, secure design, incident handling, and operational resilience.
Experience securing microservices in cloud environments and working with configuration-as-code is important for this role. Experience securing AI-driven systems, including LLM-powered services and internal automation, is highly regarded.
Strong communication skills are essential. We value engineers who can clearly communicate risk, trade-offs, and remediation paths, and who approach collaboration with empathy for engineering challenges.

Key Skills

• Strong understanding of networking, infrastructure, and applications from a DevOps perspective with a security focus.
• Hands-on experience implementing and maintaining security controls across cloud environments (particularly AWS) and access management solutions (e.g. Auth0).
• Experience with security logging, monitoring, and vulnerability assessment, with a demonstrated ability to drive findings down and improve baseline security standards.
• Passion for secure coding practices and identifying common implementation and operational security risks.

Desirable Experience

• AWS technologies such as CloudFormation, Terraform, IAM, WAF, Node.js and/or TypeScript.
• Docker, containerised environments, serverless architectures, and Kubernetes.
• Event-driven systems.
• Securing AI platforms, including LLM integrations, MCP implementations, AI guardrails, and automation/build agents.
