How to Apply for Senior Platform Engineer

at AECOM

🏢 About AECOM

AECOM is a global infrastructure leader committed to delivering a better world through sustainable design, construction, and environmental solutions. Working here means contributing to projects that have lasting positive impact on communities and the planet, while leveraging cutting-edge technology.

About This Role

As a Senior Platform Engineer, you'll architect and maintain the Azure cloud backbone for AI/ML workloads and SaaS products that drive AECOM's digital transformation. Your work will directly enable faster, more reliable deployments and ensure the scalability and security of critical infrastructure.

💡 A Day in the Life

Your day might start with a stand-up with the AI/ML team to discuss infrastructure needs for a new model deployment. Then you'll refine Terraform modules, review a pull request for a CI/CD pipeline change, and monitor dashboards in Grafana to proactively address any anomalies. After lunch, you could be architecting a cost-optimized Azure solution for a new SaaS feature, followed by a security review of a proposed architecture.

3

Tailor your CV for AECOM's mission: Emphasize how your work on cloud infrastructure has supported sustainability or large-scale infrastructure projects.

4

Include observability wins: Describe a time you used Prometheus/Grafana to detect a performance issue before it affected users, or reduced MTTR.

5

Demonstrate cross-team collaboration: Provide a concrete example of working with data scientists or product engineers to design a scalable platform.

⚠️ Common Mistakes to Avoid

  • Being too generic: Avoid listing Azure services without context—show how you used them in real scenarios.
  • Neglecting security: Don't skip mentioning security practices (e.g., RBAC, Key Vault) in your examples; it's critical for this role.
  • Overlooking team collaboration: Don't focus only on technical details; emphasize how you work with others, especially non-infrastructure teams.
