Principal Engineer (Product Architecture, JetBrains Cloud Platform) at Jetbrains

At JetBrains, we’re building an AI-native platform for software development that connects developer workflows, team-level collaboration, and organizational control into a single coherent system. This platform will serve as the execution and governance layer for AI-driven development, deeply integrated with developer tools but designed to work across teams, products, and environments. This is a long-term strategic investment for JetBrains and a key pillar of our vision for the future of software development. The role We are looking for a Software Architect (Product Architecture) to drive architecture within a specific product area. This role focuses on owning end-to-end architecture for a product domain: making sure product requirements translate into a coherent technical design, that the domain evolves sustainably, and that the product aligns with platform capabilities and constraints. You’ll be the architectural “center of gravity” for a domain, partnering closely with engineers and product stakeholders while collaborating with platform architects on shared foundations and integration contracts. As this is a new platform, many standards and processes are still works in progress – you will help define them from the perspective of real product needs and delivery constraints. As part of the team, you will: • Own the architecture of a specific product domain within JetBrains Cloud Platform and evolve it over time. • Translate product and domain requirements into clear architectural designs and implementation approaches. • Define service boundaries, domain models, data flows, and integration contracts, in line with platform standards. • Drive key architectural decisions and trade-offs in your area (e.g., API design, persistence, reliability, performance, and migration paths). • Ensure your domain architecture supports scalability, reliability, and observability from the outset. • Review and validate architectural designs within your domain and team, raising quality and consistency. • Collaborate with platform architects and other domain owners to align on cross-cutting decisions and shared interfaces. • Work closely with senior and staff engineers to clarify requirements, reduce ambiguity, and support execution. We are looking for someone who: • Has strong experience in software engineering and system design, with a track record of working on complex systems. • Has experience owning architecture within a product or domain, including balancing delivery needs with long-term sustainability. • Is comfortable aligning product needs with platform capabilities and constraints (and negotiating trade-offs when needed). • Can facilitate architectural decision-making inside a team and across partner teams. • Is comfortable working in an environment where many processes and standards are still being formed. • Is motivated by long-term goals, designing for evolution rather than one-off implementations. We’d be particularly thrilled if you: • Have experience designing product architectures that operate in cloud environments and integrate with multiple systems. • Are strong at reasoning about architectural trade-offs in context (time-to-market vs correctness, flexibility vs complexity, etc.). • Enjoy helping teams converge on good solutions through collaboration, not enforcement. #LI-DNI We process the data provided in your job application in accordance with the Recruitment Privacy Policy.
