• Own the architecture of one or more critical backend platform domains, with responsibility for design integrity, evolution, and technical debt management over time. • Act as the architectural steward, ensuring systems remain coherent, extensible, secure, and maintainable as product and customer demands evolve. • Define architectural boundaries, extension points, and contracts that enable independent evolution of platform components. • Lead the planning and execution of architecture- and code changes that improve scalability, extensibility, reliability, and developer productivity. • Ensure maintenance of the no-code principal in all platform extensions that are under your stewardship. • Translate architectural vision into mid- and long-term technical roadmaps, balancing near-term delivery with long-term platform sustainability. • Drive cross-team alignment on architectural direction, standards, and trade-offs, influencing without direct authority. • Champion a forward-leaning adoption of AI-assisted software engineering, shaping how AI tools are used across design, implementation, testing, refactoring, and maintenance. • Design platform components and extension frameworks that are AI-friendly by design, enabling automated reasoning, safer modifications, and faster iteration. • Collaborate with senior engineers and with engineering leadership to define best practices and guardrails for responsible, secure, and effective use of AI tools within the SDLC. • Continuously evaluate emerging AI capabilities and integrate those that provide material improvements in engineering leverage and system quality. • Set and uphold high standards for code quality, testing, observability, security, and operational excellence. • Drive improvements to internal developer experience, including tooling, CI/CD pipelines, documentation, and architectural guidance. • Ensure that architectural decisions are well-documented, discoverable, and actionable for engineering teams. • Mentor senior and mid-level engineers, raising the overall bar for architectural thinking and system design. • Serve as a technical multiplier—unblocking teams, accelerating decision-making, and reducing long-term complexity. • Communicate complex technical and architectural concepts clearly to both technical and non-technical stakeholders. • Stay ahead of industry trends in platform engineering, AI-enabled development, and cloud-native architectures, and drive pragmatic adoption where it delivers clear business value.
