Sydney, New South Wales, Australia JS Careers Full time $180,000 - $200,000 per year

JS Careers has been engaged to find a highly skilled .NET Architect to lead the design and delivery of large-scale, cloud-native solutions for an established digital engineering consultancy.

This role will see you working across complex enterprise environments, shaping modern architectures on AWS, and driving end-to-end technical excellence from design through to deployment.

What you'll be doing:

  • Architect, build, and maintain high-performance applications using C# and .NET Core.
  • Design and manage cloud infrastructure using AWS CDK for .NET and Terraform templates.
  • Build solutions leveraging AWS Lambda, MSK Connect, Apache Flink, Amazon Neptune, and Athena.
  • Take ownership of the entire development lifecycle — from architecture and coding to deployment and optimisation.
  • Enhance system performance, reliability, and architecture maturity with a customer-first mindset.

What we're looking for:

  • 15+ years' experience across software engineering and architecture.
  • Deep expertise in C#, .NET Core, and CDK.Net.
  • Strong background building web applications and RESTful APIs.
  • Proven experience with CloudFormation and/or Terraform.
  • Exposure to CI/CD pipelines (GitHub Actions, TeamCity).
  • Solid database knowledge — Aurora RDS, Postgres, SQL Server, or DocumentDB.

Bonus points for:

  • Experience with AWS data and streaming services (Lambda, Flink, Glue, Kinesis, Athena).
  • Understanding of core networking principles and observability tools (Grafana, Prometheus).
  • Familiarity with Liquibase/Flyway for schema migration.
  • Scripting proficiency (PowerShell, Bash, or Ansible).
  • Experience across both Windows and Linux environments.

You'll succeed if you:

  • Are a self-starter who can translate high-level requirements into technical outcomes.
  • Have a passion for clean architecture, SOLID principles, and modern engineering practices.
  • Thrive in a collaborative, autonomous environment.
  • Bring a quality-first mindset and pride in delivering solutions that last.
