Requirements

  • Have 15+ years of hands-on software development experience building cloud-native, business-critical platforms.
  • Demonstrate advanced mastery of distributed system patterns, data modeling, event-driven design, and relational and NoSQL databases.
  • Have a proven track record designing and migrating application infrastructures from monolithic architectures to modular services.
  • Bring deep experience establishing enterprise-ready patterns in AWS, including high availability, cost optimization, and secure infrastructure.
  • Have strong familiarity with modern full-stack environments, including front-end web frameworks, scripting languages, and CI/CD pipelines.
  • Have practical, production-grade experience deploying AI/ML or LLM-based solutions with observable, safe automation patterns.
  • Be fluent in English, with strong written and verbal communication skills for presenting architecture concepts to business leaders.
  • Be able to work as an individual contributor in fast-paced, ambiguous environments and take proactive ownership.
  • Be able to guide distributed engineering teams and technical peers without direct authority.
  • Be able to communicate and document technical decisions asynchronously across global time zones.

Responsibilities

  • Architect, develop, and deploy scalable, production-grade services across the core Testlio software platform.
  • Author architectural standards and reference patterns that define domain boundaries and decouple the codebase into modular services.
  • Partner with the Director of Engineering on frontend framework consolidation, operational performance, and observability.
  • Design systems with security, cost-efficiency, and ISO 27001 expectations in mind.
  • Integrate secure AI/LLM patterns into customer-facing surfaces and establish operational guardrails and failure modes for the Quality API.
  • Advise executive, product, and engineering teams on technical tradeoffs and translate business needs into technical strategies.
