Overview

UP.Labs is a dynamic venture studio dedicated to building innovative startup companies from the ground up. Our team thrives on solving complex problems, driving technological advancements, and creating impactful digital products. We're seeking a highly skilled professional to join our growing team and contribute to our mission of launching the next wave of successful startups.

Technical Challenge

We're building an agentic system as the core delivery mechanism for one of our ventures, and we're looking for a production agent-systems engineer who will own and grow the agentic function end-to-end — not a notebook builder or an ML researcher. You'll design the architecture for agents across the business, ground them in a complex proprietary domain through strong context and retrieval engineering, and build systems that take real action for real users, not just chatbots.

Responsibilities
- Own and grow the agentic function end-to-end:



set architecture across internal (data-engineering & data-science agents) and external (customer/partner-facing agents, MCP servers) surfaces, make build-vs-buy calls, and grow a team under you as we scale.
- Design, build, and deploy production LLM agents that take consequential action (write-back, execute changes) with human-in-the-loop controls — including tool interfaces (MCP, function calling), tiered tool access, approval gates, and rollback.
- Build and maintain eval harnesses for agentic systems — offline and online evaluation, regression testing for non-determinism, guardrails, and observability/tracing.
- Own context and retrieval engineering: go beyond naive chunking to build high-quality retrieval, context assembly, and grounding in proprietary domain data to reduce hallucination.
- Implement graph-based knowledge and retrieval systems (GraphRAG, property graphs, ontology/semantic layers) to ground agents in a complex, stru
