🎯 Who AECOM Is Looking For

  • Has deep hands-on experience with Azure services (e.g., AKS, Azure DevOps, Azure Networking) and can design scalable, secure cloud architectures.
  • Is proficient in Terraform for Infrastructure as Code and has built robust CI/CD pipelines using tools like Azure Pipelines or GitHub Actions.
  • Has experience implementing monitoring and logging with Prometheus, Grafana, and the Elastic stack (ELK) to ensure production reliability.
  • Collaborates effectively with cross-functional teams, especially AI/ML and product engineering, to align infrastructure with business needs.

📝 Tips for Applying to AECOM

1

Highlight specific Azure projects you've led, including the scale and impact (e.g., handling X requests per second, cost savings, uptime improvements).

2

Mention any experience with AI/ML workloads on Azure, such as deploying models with Azure Machine Learning or using GPU-based VMs.

3

Quantify your achievements in CI/CD, e.g., 'Reduced deployment time by 40% through pipeline optimization' or 'Achieved 99.9% uptime with monitoring improvements.'

4

Showcase your Terraform expertise by linking to a public repository or describing a complex infrastructure module you built.

5

Tailor your resume to emphasize security practices (e.g., IAM, network security groups, secret management) as AECOM values security in infrastructure.

✉️ What to Emphasize in Your Cover Letter

["Express passion for sustainable infrastructure and how your platform engineering skills can contribute to AECOM's mission of building sustainable legacies.", 'Emphasize your experience with Azure and Terraform, and provide a concrete example of how you improved reliability or efficiency in a previous role.', 'Highlight your ability to collaborate with AI/ML teams, showing understanding of their needs (e.g., scalable compute, data pipelines).', "Mention your commitment to security and cost-efficiency, aligning with AECOM's focus on responsible infrastructure."]

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 Describe your experience designing a scalable Azure architecture for a cloud-native application. What services did you use and why?
2 How do you approach Infrastructure as Code with Terraform? Walk us through your process for managing state and promoting changes across environments.
3 Tell us about a time you improved observability in a production system. What metrics did you track and how did you set up alerts with Prometheus and Grafana?
4 How do you ensure security in your CI/CD pipelines? Give an example of a security vulnerability you identified and mitigated.
5 Describe a situation where you had to collaborate with an AI/ML team. How did you support their infrastructure needs while maintaining cost-efficiency?

⚠️ Common Mistakes to Avoid

  • Don't be vague about your Azure experience—use specific service names and architectures, and avoid claiming expertise without evidence.
  • Avoid ignoring the AI/ML aspect; even if your background is more ops-focused, show willingness to learn or past exposure to ML workflows.
  • Don't overlook security and cost optimization; these are key in platform engineering, so failing to mention them can indicate lack of maturity.
