What You'll Do:
Applications Engineering, part of CoreWeave's Data Infrastructure organization, builds the software CoreWeave uses to plan and operate its own infrastructure business. Some of that is UNION, our data platform, where anyone in the company can query the lakehouse in plain language and stand up their own dashboards, applications, and agents. The rest is the applications behind decisions like which data centers get which hardware and when, for a company adding gigawatts of capacity a year. Engineering, finance, supply chain, and data center operations all depend on what we ship.
About the role:
You will build full-stack applications, and features in UNION itself, and own all of it in production, from the interface down to the data model. Our stack is TypeScript with React and Next.js, Python services running on Kubernetes, and Postgres alongside the lakehouse. We care more that you have built and run this kind of software than which frameworks you built it in. A good share of the work is AI-facing, meaning natural language interfaces and agents that operate on governed data, plus the evaluation work that tells you whether they are any good. Owning a product area here means you sit with the people who run the process and work out with them what the software should do. You are also the one who answers for it when it breaks. Most of these processes have never been written down anywhere, so a fair amount of the job is working out what to build before you build it.
Who You Are:
5+ years building and operating production software, including both backend services and modern web frontends
Strong Python and TypeScript, with real experience in React, Next.js, or a comparable modern framework
Experience designing and running HTTP APIs that other services depend on, including timeouts, retries, and keeping writes correct when a call fails partway through
Strong SQL and relational data modeling, including schemas you had to change after they were already live
Experience shipping LLM-backed features to production, including how you measured whether their output was correct
Hands‑on experience with containers and deployment tooling such as Docker, Helm, and Kubernetes, and with operating your own services
Experience wiring applications up to data platforms and analytical databases such as Spark, Kafka, StarRocks, or Snowflake
CI/CD, automated testing, observability, and on‑call for the software you own
Experience working directly with non‑engineers on problems nobody had specified yet, and shipping software they adopted
Preferred:
Experience building AI‑native applications such as text‑to‑SQL interfaces, copilots, agents, or automated insight generation
Experience with agent frameworks such as LangGraph, and with the tracing and evaluation tooling around them
Experience designing and running distributed systems in cloud‑native environments such as Kubernetes
Familiarity with open table formats such as Iceberg, Delta, or Hudi, and with query engines such as StarRocks, Snowflake, or BigQuery
Experience building internal platforms or tools that other teams used to answer their own questions
Background in an operationally heavy domain such as capacity planning, supply chain, or finance
Wondering if you're a good fit? We believe in investing in our people, and value candidates who can bring their own diversified experiences to our teams - even if you aren't a 100% skill or experience match. Here are a few qualities we've found compatible with our team. If some of this describes you, we'd love to talk.
You want the people using your software to be people you know by name, and you take it personally when it gets in their way
You want a product area that is yours to own end to end, from the first conversation with a user to the thing running in production
You work well at speed. Priorities here move with the business, and the problems worth solving tend to arrive on short notice
You want to know whether the AI in your product is any good, and you will build the evals to find out
You stand behind what you ship, whether you wrote it or a model helped you write it
Why CoreWeave?
At CoreWeave, we work hard, have fun, and move fast! We're in an exciting stage of hyper‑growth that you will not want to miss out on. We're not afraid of a little chaos, and we're constantly learning. Our team cares deeply about how we build our product and how we work together, which is repre
