HybridRedwood City, California, United States
Job Summary
Own the design and delivery of individual systems end-to-end, from scoping with business stakeholders through production deployment. Build production applications used daily by business teams, including custom agents, workflows, and knowledge infrastructure that reason over connected enterprise data. Partner with the tech lead on architecture decisions and contribute strong points of view on tradeoffs and reusable patterns. Potentially contribute to the team's cloud footprint, handling pragmatic infrastructure decisions, deployment, and observability. This high-autonomy senior IC role focuses on building internal tools and AI-powered workflows that make business teams more effective. Success is measured by systems adopted by teams and durable technical patterns that reduce rebuilds. The position requires 5+ years of senior IC experience, strong full-stack fundamentals, and direct production experience with LLM-based applications and agent frameworks.
Required Qualifications
- 5+ years building production software systems as a senior IC, with a track record of owning meaningful surfaces end-to-end
- Strong full-stack engineering fundamentals — comfortable shipping production applications, backend services, and the integration layer between them
- Direct production experience building LLM-based applications, custom agents, or agentic workflows
- Strong API integration experience at the enterprise SaaS layer — auth, rate limits, schema drift, failure modes
- Working fluency with MCP, LLM tool/function calling, current agent frameworks, and retrieval/knowledge infrastructure (knowledge graphs, vector stores, RAG)
- Comfort with ambiguity; ability to make progress when requirements are evolving
- Strong stakeholder fluency; you can hold technical conversations with business partners without a translator
- This role is a hybrid position requiring you to be onsite for at least 60% of the working month, approximately 3 days a week
Desired Qualifications
- Nice to have: Background in enterprise IT, business systems, or platform engineering; experience operating cloud infrastructure (AWS, Terraform) for production systems
