What Will Make You a Great Fit: • Industry Veteran: 10+ years in software engineering, with 5+ years in a Principal or Architect role • Deep Expertise: Expert-level C# or other OOP languages such as Java/Python. RESTful APIs, Microservices, Domain-driven design, CI/CD, Event-driven architecture, Service-oriented architecture, High-availability, containerization, SQL and NOSQL • Cloud & Infrastructure Experience: AWS (ECS, EKS, RDS, Lambda, S3, SQS, CloudFormation), Terraform . • Security & Compliance Experience: OWASP best practice, OIDC, SAML2, SOC2, ISO27001, HIPAA • Proven Track Record: Success in shipping multiple complex products with stable, maintainable architectures. • Strategic Communicator: Ability to translate complex technical concepts for both engineers and executive leadership. • Pragmatic Problem Solver: Balanced approach to solving immediate production needs while maintaining long-term architectural health. • Innovation Focused: A passion for replacing legacy workflows with scalable, R&D-driven solutions.
