Founded in 2017, CoreWeave became a publicly traded company (Nasdaq: CRWV) in March 2025. Learn more at www.coreweave.com . What You'll Do: The Field Engineering organization at CoreWeave supports the clients running some of the largest AI workloads in the world. This team builds the tooling that engineers rely on to identify and diagnose customer issues faster. We work where AI and deterministic based systems meet live production infrastructure, so what we build has to be accurate, has to show its reasoning, and has to earn the trust of engineers who are the real experts solving issues. About the Role: As an AI Engineer, you'll design, build, and operate systems that engineers use during real customer incidents. You will define the right balance between deterministic and AI systems, and work with both. For AI systems, you'll own the agent logic, the retrieval behind it, the safeguards that stop it from acting on bad information, and the measurement that tells us whether it's actually helping. This is a full-ownership role: you ship your own services and stay responsible for how they behave in production. You'll work closely with the engineers who use what you build. In this role, you will: - Design and build AI agents that investigate and act on real customer issues. - Build the safeguards that make that safe: grounding model output in authoritative data, requiring human approval before consequential actions, and defining the conditions under which the system should stop. - Build and evaluate retrieval over a large body of historical support data, measured against how experienced engineers handled the same problems. - Determine the optimal balance between AI and deterministic logic. - Instrument these systems for quality, cost, and adoption, then use what you learn to decide what to build next. - Deploy and operate your own services on Kubernetes, including supporting them when something breaks. - Partner with support engineers and domain experts, including sitting in on live investigations to see where automation helps and where it gets in the way. Who You Are: - 3+ years of professional software engineering experience, with strong proficiency in Go or Python. - Experience taking an AI application from prototype to production use and supporting it afterward. - Hands-on experience with agent patterns: tool and function calling, multi-step orchestration, and handling incorrect model output. - Experience building and evaluating retrieval systems, including measuring quality against a baseline using held-out data. - Experience designing controls for automation that acts on production systems, such as approval steps, idempotency, and audit trails. - Experience diagnosing failures in LLM applications and fixing the underlying cause rather than the symptom. - Experience with observability for LLM applications, including tracing, cost, and latency. - Working knowledge of Kubernetes and experience deploying services through CI/CD. - Experience integrating with third party APIs, including authentication and secrets handling. Preferred: - Experience building conversational or chat-based interfaces for internal users. - A background in infrastructure, SRE, or technical support, and comfort reading logs and metrics from a live system. - Experience testing both deterministic and non-deterministic systems. - Experience with fine-tuning or building training datasets from production data. - Open source contributions to AI tooling or agent frameworks. 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 can tell the difference between the thing that's interesting and the thing that's urgent, and you'll say so out loud when they aren't the same. - You've worked with a team that already had tooling they liked, and found the integration instead of arguing for a rewrite. - You'd rather sit in on a real incident than infer how the work goes from a ticket. - Blunt feedback from the engineers using your software is the most useful thing you'll hear all week, and you don't get defensive about it. The base salary range for this role is $143,00 to $210,000. The starting salary will be determined based on job-related knowledge, skills, experience, and market location.

About the Role We're seeking an Engineering Manager to lead a full-stack team building Go backend services and React/TypeScript frontends for workflow-heavy, data-dense products with real users you can talk to: hardware ticketing automation, guided repair procedures for technicians on the data center floor, and the services that move hardware and inventory data across the fleet. Your users are the data center technicians, operations engineers, technical program managers, and inventory specialists who run CoreWeave's global footprint. You own delivery, including scope, release cadence, quality, and responsiveness to users. You’ll lead design reviews, pressure-test architecture, and help your team make sound tradeoffs. In this role, you will: Lead and grow the team through hiring, onboarding, career development, and performance management, and set the tone for how the team operates and enables the rest of CoreWeave. Own delivery end to end: gather and refine requirements, define scope, and set predictable, clearly communicated release cadences. Drive reliability and performance under real operational load through observability, on-call operations, incident response, runbook development, and automated remediation. Lead maintenance and enhancement of existing products, soliciting user feedback and prioritizing fixes to stay responsive to users. Scope and lead new product development that increases the efficiency and scale at which CoreWeave manages its fleet. Set technical direction through design and architecture reviews, holding the bar on API contracts, data modeling, and frontend architecture. Partner with peer Fleet Engineering teams and operations leadership on shared APIs, sources of truth, and cross-team dependencies. Who You Are 8+ years of professional software engineering experience, including 4+ years managing full-stack teams that ship and operate production web applications across a frontend layer (TypeScript/React or comparable) and backend services (Go, or another compiled service language). Demonstrated track record delivering software products to defined stakeholders and users: requirements gathering, scoping, prioritization, release planning, and predictable delivery cadences. Experience owning production web services end to end, including performance under load, availability targets, on-call rotations, and incident response. Technical depth sufficient to lead design and architecture reviews and evaluate system design tradeoffs across API contracts, data modeling, state management, horizontal scaling, security, and audit trails. Experience hiring, mentoring, and managing engineer performance, including growing engineers into senior and lead roles. Strong process-oriented mindset and the ability to document, scale, and optimize complex workflows. Excellent cross-functional communicator, comfortable extending your influence to non-engineering stakeholders, partner teams, and senior leadership. Bachelor's or Master's degree in Computer Science, Engineering, or equivalent practical experience. Preferred Experience delivering internal tools, workflow products, or field-service platforms used daily by operational teams, with strong product sense for translating user workflows into interfaces. Experience with third-party and vendor API integrations, including ticketing systems such as Jira and vendor support portals. Familiarity with data center operations, hardware lifecycle management, or asset tracking and DCIM tools. Experience with mobile-friendly or device-integrated web applications, for example barcode or serial number scanning. Familiarity with observability platforms (Prometheus, Grafana, VictoriaMetrics, alerting systems), Kubernetes, and modern CI/CD practices. The base salary range for this role is $165,000 to $242,000.
