About the Role
Tomorrow.io’s Saas department is focused on building software and products at scale, from infrastructure that handles massive amounts of data to outstanding customer centric user experiences in B2B, B2C and B2D products that change billions of lives worldwide.
We're seeking a Staff engineer - AI Builder to lead the design and implementation of AI-native technical frameworks that redefine how large-scale systems are built, extended, and evolved.
This role is deeply technical and architecture-driven, focused on designing modular, extensible, and AI-first system foundations that enable scalable development with AI as a core engineering collaborator.
You will work across the full stack, building infrastructure where AI actively generates, extends, and maintains software components as part of the native development flow.
This is not about incremental AI integration — this is about architecting the frameworks that let AI scale software engineering 10x faster and smarter.
Responsibilities
- Architect and lead the development of AI-native system frameworks that emphasize modularity, extensibility, and adaptive scalability.
- Build platform primitives that enable dynamic AI-driven module and extension generation.
- Design and implement developer workflows optimized for AI-assisted software development, embedding AI collaboration as a first-class design principle.
- Define and codify AI-native engineering practices, patterns, and guidelines to elevate Tomorrow.io’s software development lifecycle.
- Establish and champion best practices for AI-assisted engineering across system design, code quality, testing, observability, and operational scalability.
- Drive hands-on prototyping and iterative delivery across frontend, backend, and orchestration layers.
- Provide technical leadership and mentorship, fostering an AI-first engineering culture across teams.
- Partner closely with Product, AI, and Engineering teams to align system evolution with AI-native goals.
Requirements
- Strong builder’s mindset — balancing deep system thinking with practical, hands-on delivery.
- 10+ years of full stack system architecture and complex platform engineering experience.
- Deep expertise designing distributed, composable, and extensible systems across frontend and backend environments.
- Strong hands-on skills with frontend frameworks (e.g., React, Next.js) and backend systems (e.g., Node.js, Python, Go, microservices, event-driven architectures).
- Proven experience integrating and operationalizing AI-assisted development tools (e.g., GitHub Copilot, Cursor) into engineering workflows.
- Experience building plugin frameworks, extension systems, or developer platforms that emphasize modularity and scalability.
- Track record of defining and promoting engineering best practices — especially in the context of AI-driven development.
- Demonstrated technical leadership — mentoring engineers, shaping architecture standards, and driving adoption of new paradigms.
