Position Overview:

  • Demonstrable experience architecting and building highly scalable SaaS platforms, with a background in supporting systems that process a high frequency of transactions.
  • Proven experience deploying and running .NET applications in an AWS environment (e.g., ECS, Lambda, Elastic Beanstalk).
  • Deep expertise with databases (SQL and/or NoSQL), with hands-on experience using ORMs like Entity Framework Core.
  • Solid grasp of modern API design principles (REST, GraphQL). Demonstrable experience designing new APIs, managing their lifecycle with effective versioning, ensuring backwards compatibility, and implementing security best practices (e.g., OAuth, JWT).
  • An analytical mind with a strong aptitude for problem-solving, particularly in relation to system security.

Bonus Points For:

  • Hands-on experience with the System.Security.Cryptography namespace and implementing custom cryptographic solutions in .NET.
  • Experience working in environments compliant with PCI-DSS or ISO 27001 standards.
  • Strong AWS DevOps skills (IaC with Terraform/CloudFormation, IAM, VPC).
  • Experience with .NET applications running on a horizontally scaled Amazon ECS environment.
  • Hands-on experience with Generative AI or integrating LLMs into .NET applications.

What We Offer:

  • A collaborative and innovative work environment.
