• Define Architectural Strategy: Set the long-term technical roadmap, engineering standards, and core technology adoption (engine, backend, rendering).
• Drive Technical Governance: Act as the final authority on critical design decisions, establish quality gates, and manage performance budgets.
• Lead Hands-On Innovation: Prototype foundational systems, perform high-level code reviews, and solve high-risk architectural challenges.
• Mentor Team: Coach team members to foster a culture of technical rigor and continuous improvement.
• Risk Management: Identify and mitigate technical debt, performance bottlenecks, and architectural risks across the development lifecycle.
• Cross-Disciplinary Partnership: Align technical architecture with regulatory and commercial objectives.
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.
