Principal Software Architect

Role overview Shape the architecture of a software platform for distributed quality testing, while remaining a hands-on individual contributor who builds production systems. The role focuses on evolving a monolithic application toward modular services and adding practical, secure AI capabilities to high-throughput customer-facing workflows. It calls for broad technical influence across engineering, product, and executive stakeholders.

Responsibilities - Design, build, and deploy scalable services across the core platform. - Define architectural standards and reusable patterns that clarify domain boundaries and support decoupling the existing application into modular services. - Partner with engineering leadership on frontend framework consolidation and improvements to performance and observability. - Integrate AI and language model capabilities into customer-facing surfaces, with clear security controls, operational safeguards, and failure handling. - Account for system security, cost efficiency, and ISO 27001 expectations in architecture decisions. - Advise business and technical leaders on major tradeoffs, turning product needs into practical technical plans.

Requirements - At least 15 years of hands-on software development experience building cloud-native, business-critical platforms. - Deep knowledge of distributed systems, event-driven design, data modeling, and relational and NoSQL databases. - Experience designing and migrating applications from monolithic architectures toward modular services. - Strong AWS architecture experience, including availability, security, and cost optimization. - Production experience with AI, machine learning, or language model solutions, plus familiarity with full-stack environments and CI/CD. - Excellent English communication skills and the ability to guide distributed teams, document decisions asynchronously, and deliver as an individual contributor in ambiguous settings.

Benefits and work setup Fully remote role open to candidates residing in the United States, United Kingdom, or EMEA. Benefits include flexible paid time off, stock options, and an annual learning stipend of $300.
