About Port At Port.io, we are building an open and flexible Agentic SDLC Platform for modern engineering organizations. Following our recent $100M Series C funding round, we are in a phase of rapid hypergrowth with strong enterprise momentum. We act as the central nervous system for engineering, enabling platform teams to unify their stack and expose it as a governed layer through golden paths for developers and AI agents. By combining rich engineering context, workflows, and actions, we help organizations transition from manual processes to autonomous, AI-assisted engineering workflows - while maintaining control and accountability. As a product-led company, we believe in building world-class platforms that fundamentally shape how modern engineering organizations operate. About the Role This is a rare, high-leverage role at the intersection of deep technical craft and strategic platform thinking. As Port's Principal Software Architect, you will own the technical vision for our foundational infrastructure and shape how engineering works across every team in R&D. You won't be embedded in a single product team — you'll operate across the entire R&D organization, tackling the hardest architectural challenges: data modeling at scale, integration system design, enterprise readiness, performance, and cost efficiency. You'll report directly to the VP of R&D and serve as a technical force-multiplier for our directors and team leads. If you want to architect systems that serve thousands of engineering organizations — and leave fingerprints on every layer of a fast-scaling SaaS platform - this role is for you. What You'll Do System Design & Scaling Architect robust, high-performance, and scalable systems across our entire platform. Lead the design of resilient, performant, and maintainable core infrastructure as we evolve our SaaS ecosystem. Design a more robust, performant, and generic integration layer — making our 3rd-party integrations more scalable, easier t
