Principal Full Stack Developer & Solutions Architect – AI, Data & Cloud - San Jose, United States
Originally posted 29 September 2026 by the employer.
About the role
This Principal Full Stack Developer and Solutions Architect will design and build AI, data analytics, and cloud solutions for the Product Development engineering organization.
What you'll do
- Own end-to-end solution architecture for Product Development use cases spanning AI/ML, data analytics, and cloud.
- Design agent systems for engineering workflows, including tool use, orchestration, and human-in-the-loop controls.
- Architect the data and retrieval layer for AI and analytics solutions, covering ingestion, modeling, semantic layers, and access patterns.
- Architect solutions for AWS and containerized runtimes, balancing performance, reliability, and cost.
- Build applications end-to-end: backend services, orchestration logic, APIs, data access, and user-facing surfaces.
- Partner directly with Product Development engineers to identify, scope, and co-develop solutions.
What you'll need
- Bachelor’s degree in Computer Science, Engineering, Physics or a related field.
- 8+ years of professional software engineering experience, including production ownership of systems designed.
- Demonstrated solution architecture experience spanning application, data, cloud, or AI, with the ability to own a design end-to-end.
- Strong Python and SQL; proficiency in a modern front-end stack (React/TypeScript) or rapid UI frameworks (Streamlit, Gradio).
- Demonstrated experience building LLM-based applications with orchestration frameworks (LangGraph, Langflow, or equivalent), including tool/function calling and MCP-based integrations, and practical experience with RAG architectures.
- Hands-on experience with data engineering and analytics tooling — pipeline orchestration (Airflow, dbt, or equivalent), warehouse or lakehouse platforms, and BI or visualization tools.
- Solid AWS experience, including containerized workloads (Kubernetes/EKS), infrastructure-as-code, and cost-aware architecture.
- Working knowledge of evaluation methodology for non-deterministic systems, with a track record of measuring quality rather than asserting it.
- Ability to work on-site in San Jose, CA, with regular embedded time alongside engineering teams.
Nice to have
- Prior delivery of an AI or analytics solution in production at meaningful scale, with adoption evidence.
- Experience in semiconductor, storage, or hardware product development environments, including engineering and test data.
- Familiarity with engineering toolchains — GitHub, Jira, Confluence, CI/CD systems, and test data platforms.
- Design-system literacy and prior ownership of a developer-facing product surface.
- Experience operating within an enterprise AI platform (LLM gateway, RAG-as-a-service, managed inference) and enterprise data governance frameworks.
