senior cloud security engineer

Bilue is a digital consultancy that designs and builds smart, user-friendly technology for some of Australia’s most well-known businesses. From mobile apps to beautifully designed web platforms and digital experiences, we create solutions that drive impact and deliver exceptional customer outcomes.

Our culture is people-first and purpose-driven. We are a down-to-earth, values-led team with offices in Sydney and Melbourne, and a growing presence in Manila. We genuinely enjoy working together, whether we are solving tough tech problems, brainstorming creative solutions, or grabbing a coffee between meetings. Curiosity is encouraged. Collaboration is second nature.

We value excellence, not ego, and back each other to do great work without micromanagement. With low politics and high trust, it is a place where delivery people, designers, and engineers genuinely connect. Everyone has a voice, the space to grow and have a little fun along the way.

As a Senior Cloud Security Engineer at Bilue, you own the security, compliance and operational integrity of the AWS and Azure platforms we run for our clients, including their AI workloads. 

You will run the infrastructure, harden the pipelines, take the alerts our SOC partner escalates through to closure, and keep our ISO 27001 evidence audit ready.This is a hands-on role inside the codebase, working alongside our engineers rather than reviewing their work from a distance.

RESPONSIBILITIES

• Operate and maintain AWS and Azure infrastructure, CI/CD pipelines, infrastructure as code and environment configuration across client platforms

• Triage security alerts escalated by our third party SOC, drive each one through to remediation and closure, and lead the post incident review

• Monitor security posture and manage vulnerability remediation across the infrastructure and application layers, including patching and dependency updates

• Review pull requests alongside the development team and embed security controls into build and deployment processes in line with agreed policies

• Manage identity, access controls, secrets and API credentials across both clouds, including key rotation and least privilege reviews

• Maintain observability, alerting, backup and disaster recovery capability, and run regular recovery and restoration testing

• Maintain infrastructure and security compliance to ISO 27001, covering configuration standards, logging, audit evidence and closure of control gaps

• Use AI responsibly and in line with Bilue's AI policies, treating it as a tool to work smarter while keeping human judgement at the centre of your decisions

• Act as the escalation point for critical security alerts outside business hours, with an allowance provided

WHAT WE'RE LOOKING FOR

Mindset & Experience

• Real craft in your work, you build the security gate rather than only switching on the scanner, and you care that a fix actually holds

• A consultative approach, you can explain a risk and its trade offs to a client or an engineer without hiding behind jargon

• A passion for connection, you share what you find and lift the security knowledge of the whole team rather than keeping it to yourself

• Ownership and accountability, happy to be the security escalation point and to take an alert through to closure without being chased

• A drive to shape solutions, curious enough to trace a dependency alert through to real exploitability in the codebase and then work with developers on the fix

Technical Skills

• Strong hands on experience operating production workloads across both AWS and Azure in a cloud security, DevSecOps or platform engineering role

• Cloud security services in production. GuardDuty, Security Hub, IAM, KMS and CloudTrail on the AWS side, or Defender for Cloud, Entra ID, Key Vault and Azure Policy on the Azure side

• Confident writing and reviewing Terraform or equivalent infrastructure as code

• Able to read application code, raise security issues at the code level, and understand how APIs, services and databases fit together in a running platform

• Able to diagnose faults across the stack and run root cause analysis, tracing a vulnerability from a dependency alert through to real exploitability, then working with developers on the fix

• CI/CD pipeline experience, including building the security gates rather than only configuring a scanner

• Practical security alert triage and incident response alongside an external SOC or MSSP

• Working knowledge of ISO 27001 controls and audit evidence

• AWS Security Specialty, AZ-500 or an equivalent certification
   

Nice to Have

• A background in platform or backend delivery, with experience building and shipping systems rather than only securing them
