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. Founded in 2017, CoreWeave became a publicly traded company (Nasdaq: CRWV) in March 2025. Learn more at www.coreweave.com.

What You’ll Do:

Weave is CoreWeave’s observability, evaluation, and monitoring platform for AI agents and GenAI applications. Our customers rely on Weave to build the auto-improving loop for their AI agents: including production tracing, offline evaluations, online monitoring and alerting.

About the Role:

We’re looking for Software Engineers to help build and scale Weave. In this foundational role on a small but growing team, you’ll design and ship core functionality, gather feedback directly from users and customers, and continuously improve the product experience. You’ll work closely with cutting-edge AI builders, developing the next generation of tools that help teams understand, evaluate, and iterate on their AI agents.

Implement robust and ergonomic APIs.
Design and build integrations with popular agent harnesses and SDKs such as Claude Code, Codex, pi.dev, OpenAI Agents SDK, etc.
Scale and improve backend performance to support low-latency, high-volume production use cases.
Build polished and intuitive features such online LLM judges, playgrounds, evaluations, labeling, and tracing UX.
Partner directly with users to understand workflows, gather feedback, and rapidly iterate on solutions.

Who You Are

Bachelor’s degree in Computer Science or related field.
8+ years of experience in Software Engineering.
Deep knowledge of Python and/or TypeScript.
Experience (personal or professional) in building AI agents.
Ability to operate effectively amid ambiguity and adapt rapidly to a changing environment.
Previous startup experience is a plus.

Preferred

Experience managing large-scale online production services or OLAP databases.

Wondering if you’re a good fit? We believe in investing in our people and value candidates who bring diverse experiences - even if you aren’t a 100% match. Here are a few qualities that tend to resonate with our team:

You thrive at the intersection of software, hardware, and ML infrastructure - from tuning distributed systems to scaling backend services.
You’re passionate about building tools that developers love to use - intuitive APIs and UX that bring clarity and speed to AI workflows.
You’re curious about the full AI lifecycle - from experiment tracking and model deployment to observability and evaluation - and want to shape an end-to-end platform that redefines how AI is built and scaled.

Why Us?

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 represented through our core values:

Be Curious at Your Core
Act Like an Owner
Empower Employees
Deliver Best-in-Class Client Experiences
Achieve More Together

We support and encourage an entrepreneurial outlook and independent thinking. We foster an environment that encourages collaboration and provides the opportunity to develop innovative solutions to complex problems. As we get set for takeoff, the growth opportunities within the organization are constantly expanding. You will be surrounded by some of the best talent in the industry, who will want to learn from you, too. Come join us!

The base salary range for this role is $165,000 to $220,000. The starting salary will be determined based on job-related knowledge, skills, experience, and market location. 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). What We Offer

The range we’ve posted represents the typical compensation range for this role. To determine actual compensation, we review the market rate for each candidate which can include a variety of factors. These include qualifications, experience, interview performance, and location.

In addition to a competitive salary, we offer a variety of benefits to support your needs. The benefits below reflect our US-based offerings for full-time employees; for roles in other locations, benefits vary and are shared during the hiring process. These include:

Medical, dental, and vision insurance - 100% paid for by CoreWeave
