About the role

Key responsibilities & impact

Own the design and delivery of individual systems end-to-end — from scoping with business stakeholders through production deployment
Build the production applications business teams use day-to-day
Design and build AI features — custom agents, workflows, and the knowledge and retrieval substrate that lets them reason over connected enterprise data
Partner with the tech lead on architecture decisions; contribute strong points of view on tradeoffs, patterns, and reuse
Potentially contribute to the team's cloud footprint over time — pragmatic infrastructure decisions, deployment, observability, and reliability for what the team ships, as the scope of the team develops
Partner with senior business stakeholders and embedded engineers across the organization

Requirements

What you’ll need

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.
Nice to have:
Background in enterprise IT, business systems, or platform engineering
Experience operating cloud infrastructure (AWS, Terraform) for production systems
