Job Description

About the Role

We are partnering with a premier, specialized software engineering and technical consultancy that builds mission-critical, data-intensive systems for tier-one banking and financial institutions.

On their behalf, we are looking for a DevOps / Platform Engineer with a strong C#/.NET development background to bridge the gap between application development and platform reliability. In this role, you will play a critical part in modernizing, supporting, and automating complex enterprise infrastructure across data-intensive financial platforms.

Key Responsibilities

  • Support, automate, and streamline infrastructure across on-premise, virtualized, and legacy environments.
  • Read, debug, and troubleshoot application-layer C#/.NET code alongside development teams to maintain system reliability.
  • Configure, maintain, and enhance CI/CD pipelines (TeamCity, Octopus Deploy, Jenkins, Azure DevOps).
  • Assist with the management and gradual migration of legacy enterprise deployment systems toward modernized pipeline standards.
  • Automate IIS server instances, deployment scripts, and deployment infrastructure in highly secure environments.
  • Ensure maximum uptime, security compliance, and performance for mission-critical financial and data platforms.

Required Skills & Experience

  • Total Experience: 5-10 years across Software Engineering, Platform Engineering, or DevOps-striking the right balance between solid seniority and hands-on execution.
  • C# / .NET Software Background: Strong foundations as a developer with previous hands-on C#/.NET coding experience. You must be comfortable reading, debugging, and tracing application code to resolve deep platform issues.
  • On-Premise Infrastructure Focus: Direct experience managing and automating traditional on-premise infrastructure, Windows Server/IIS environments, and virtualized/bare-metal systems.
  • CI/CD & Pipeline Tooling: Hands-on experience with build and deployment tools such as TeamCity, Octopus Deploy, Azure DevOps, or Jenkins, alongside the adaptability to work with legacy enterprise deployment engines.
