[Hiring] Principal Software Architect @Testlio

Role Description

We are hiring a Principal Architect to serve as a hands-on individual contributor who will shape our application and platform architecture, driving production-ready systems that directly enable our next generation of intelligent, distributed software testing solutions.

• High Ownership and Autonomy: Be a foundational technical leader steering a profound platform transformation, making critical structural decisions that balance immediate system delivery with long-term enterprise scalability.
• Pragmatic AI & System Innovation: Step past the hype to integrate actionable AI capabilities directly into high-throughput surfaces, modernizing our core monolith into a robust distributed network alongside our product and executive leaders.

What would your day look like?

• Architect, develop, and deploy scalable, production-grade services directly across the core Testlio software platform.
• Author clear architectural standards and reference patterns that define domain boundaries, decoupling our current codebase into modular services.
• Partner with the Director of Engineering to execute frontend framework consolidation, improving operational performance and observability.
• Safeguard system efficiency and regulatory posture by designing with security, cost-efficiency, and ISO 27001 expectations at the center.
• Integrate secure AI/LLM patterns into customer-facing surfaces, establishing strict operational guardrails and failure modes for our Quality API.
• Advise executive, product, and engineering teams on major technical tradeoffs, translating business needs into clean technical strategies.

Qualifications

• 15+ years of hands-on software development experience building cloud-native, business-critical platforms.
• Advanced mastery of distributed system patterns, data modeling, event-driven design, and database technologies (Relational and NoSQL).
• Proven track record designing and migrating application infrastructures, specifically moving from monolithic architectures to modular services.
• Deep experience establishing enterprise-ready patterns in AWS, emphasizing high availability, cost optimization, and secure infrastructure.
• Strong familiarity with modern full-stack code environments, including front-end web frameworks, scripting languages, and CI/CD pipelines.
• Practical, production-grade experience deploying AI/ML or LLM-based solutions with an emphasis on observable, safe automation patterns.

Requirements

• Fluency in English with exceptional written and verbal communication skills, especially when presenting advanced architecture concepts to business leaders.
• Ability to operate effectively as an individual contributor in fast-paced, ambiguous environments, showing proactive problem ownership.
• Strong collaboration and alignment focus, capable of guiding distributed engineering teams and technical peers without direct authority.
• Outstanding analytical thinking, balancing a broad long-term technology vision with practical, short-term implementation constraints.
• Natural inclination for remote-first work, successfully communicating and documenting technical decisions asynchronously across global time zones.

Benefits

• Flexible paid time off—including national holidays, personal days, and sick days.
• Stock options to grow with Testlio.
• $300 annual learning stipend to support personal and professional development.

Company Description

• Testlio is a female-founded company, and half of our team identifies as women.
• We’re proud of our inclusive, purpose-driven culture where people genuinely enjoy collaborating.
