Mission Objectives
As part of the Application Platform team, the Senior Platform Engineer will:
Operate, maintain and improve application platforms where in-house applications are deployed (on-prem + Kubernetes managed platform).
Support development teams in deploying their applications, from solution design to production go-live.
Troubleshoot and resolve incidents related to platform components and application deployments.
Standardize and industrialize platform practices (deployment patterns, reliability, observability, documentation, support procedures).
Technically coach junior engineers and help the team grow its platform expertise.
Project Context / Environment
The client runs two main application platforms to host internally developed applications:
An on-prem platform based on Windows Application Servers
A cloud-native platform based on Kubernetes (AKS) to host containerized applications
The Role Sits At The Intersection Of
Kubernetes / cloud platform engineering
production support (run) + continuous improvement
developer enablement and architecture support
Key Responsibilities
Design, implement and manage changes to the application platforms (Windows Server + Kubernetes AKS).
Maintain platform software components and document support procedures.
Support developers and application architects during:
solution design
implementation
deployment to production
Analyze and troubleshoot technical issues, incidents and platform/application errors.
Propose and drive improvements to platform reliability, security and automation.
Coach other team members (especially junior engineers) on platform components and operational best practices.
Potential participation in an on-call / 24/7 duty rotation (1 week every 4 weeks, on request).
