The product
We believe the next generation of data infrastructure will be built for agents first.
Modern data warehouses like Snowflake, Databricks, and Google BigQuery are now the default layer for centralizing data and are quickly becoming the foundation for how AI agents operate on company data.
Weld is a data infrastructure platform built to be integrated programmatically by developers and agents. Our pipelines move data at scale across hundreds of integrations, and our platform is increasingly the backbone for agentic data workflows, both for our customers and internally.

The role
This is an AI platform engineering role focused on building agentic systems on top of modern data infrastructure and working directly with customers to deploy them in production.
You will spend part of your time working directly with customers, onboarding them, guiding them through complex data setups, and helping them implement and operate Weld within their agentic workflows. The rest of your time will be spent turning what you learn into systems, building agentic workflows, shipping AI-powered tooling, and shaping how Weld is built for agents.
You will use Weld to build and operate internal agentic systems, directly shaping the product’s evolution. Alongside this, you will work with APIs such as the Anthropic API and tools like Claude Code to design agentic data infrastructure and define how Weld exposes itself to agents through APIs and tool interfaces.
This role is a great fit for someone early in their career who wants to take ownership and build real systems and agentic workflows in production.

Some nice things about working at Weld
Our values
Extreme customer focus
Putting our customers first has been and will continue to be our top priority. Our ability to make our customers happy will define our long-term success.
Execution over ideas
Action beats inaction. We move fast, make decisions fast, and learn by doing. Momentum matters, and focusing on what moves us forward keeps our impact high.
Quality in every line
Craft matters. We take pride in thoughtful, reliable work that reflects our standards. High quality in everything we ship is how we create lasting value for customers.
Our Mission
Most companies sit on valuable data they cannot actually use. The tooling is too complex, the expertise too scarce, and the setup too slow. Weld exists to change that by making data infrastructure accessible not just to humans, but to systems and AI agents that can operate on it directly. We make it possible for companies to build on their data programmatically, whether that is an analyst exploring data, a developer integrating via an API, or an AI agent running automated workflows against their warehouse.
