Fragment is hiring Software Engineers in San Francisco to build the core platform behind its AI agents for enterprise procurement. The company came out of stealth in October 2026 with $56 million in funding, and its agents resolve purchase order and invoice exceptions inside the systems large manufacturers and distributors already run.
This is a foundational engineering role, not a feature team role, shaping the platform every agent and workflow will rely on.
What you will do
- Design and own systems that do not exist yet, the foundational architecture for AI agents working over complex enterprise data.
- Build a distributed agent pipeline that processes tens of millions of data points with deterministic, auditable and multi-tenant-safe behaviour.
- Define and develop an automation editor that takes a visual-text hybrid approach to workflow design and adapts itself to each customer’s processes.
- Engineer graph traversal and indexing systems that enable fast, lossless reasoning over Fragment’s unified data interface and arbitrary customer data systems.
- Define the core framework for self-assembling agents that compose and execute workflows autonomously, safely, predictably and with full traceability.
You may be a fit if you
- Have 3 to 7 or more years of experience and describe yourself as a high-slope generalist who gets restless when not building things that matter.
- Learn unusually fast and thrive in ambiguity rather than waiting for a fully specified brief.
- Think in systems, not tickets, and want to own architecture, product and customer impact together.
- Ship high-quality work quickly and have seen high-quality production code across the stack.
- Get excited by messy enterprise data and hard problems instead of clean, well-bounded tasks.
