  • Collaborate with cross-functional teams to translate business needs into technical solutions.
  • Evaluate emerging technologies and recommend adoption strategies aligned with organizational goals.
  • Support implementation of cloud-native architectures, microservices, and API-first design.
  • Drive automation in deployment, testing, and operational practices to improve system reliability and efficiency.
  • Partner with security teams to embed security and privacy considerations into architecture and delivery.

Required Qualifications

  • Bachelor's degree in computer science, engineering, or a related field.
  • Extensive experience in enterprise application development with C#, ASP.NET, ASP.NET Core, and modern.NET platforms.
  • Proven experience designing and implementing large-scale distributed systems in production.
  • Strong understanding of software architecture principles and patterns, with sound judgment on when to apply them.
  • Demonstrated ability to lead technical initiatives across multiple teams without direct authority.
  • Experience delivering cloud-based solutions, preferably in Azure.
  • Strong problem-solving skills, including diagnosing production incidents in complex systems.
  • Excellent written and verbal communication skills, with the ability to influence senior stakeholders.

Preferred Qualifications

  • Experience with cloud platforms, especially Microsoft Azure, at an enterprise level.
  • Knowledge of platform engineering and internal developer platform practices.
  • Familiarity with event-driven architecture and messaging platforms.
  • Experience building mission-critical applications with defined SLAs/SLOs.
  • Background in regulated industries such as healthcare, financial services, or pharmaceuticals.
  • Leading large-scale legacy modernization or cloud migration programs.
  • Relevant certifications such as Microsoft Certified Azure Solutions Architect Expert or Azure DevOps Engineer Expert.
  • Experience with SRE practices, including SLOs, error budgets, and incident management.
  • Contributions to open source projects, technical publications, or industry conferences.
  • Experience integrating AI/GenAI capabilities into enterprise solutions.
