Software Engineer

Senior Software Engineer I Bellevue, WA / Sunnyvale, CA / San Francisco, CA / Livingston, NJ / Manhattan, NY / Philadelphia, PA / Dallas, TX CoreWeave is The Essential Cloud for AI™. Built for pioneers by pioneers, CoreWeave delivers a platform of technology, tools, and teams that enables innovators to build and scale AI with confidence. Trusted by leading AI labs, startups, and global enterprises, CoreWeave combines superior infrastructure performance with deep technical expertise to accelerate breakthroughs and turn compute into capability.

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. 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 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 Experience building AI-native applications such as text-to-SQL interfaces, copilots, agents, or automated insight generation Experience designing and running distributed systems in cloud-native environments such as Kubernetes 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 Here are a few qualities we've found compatible with our team. 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 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 As we get set for take off, the growth opportunities within the organization are constantly expanding. We strive for both market alignment and internal equity when determining compensation. In addition to base salary, our total rewards package includes a discretionary bonus, equity awards, and a comprehensive benefits program (all based on eligibility).
