Senior Software Engineer - Agentic AI, Internal Developer Platforms

CoreWeave is The Essential Cloud for AI™, delivering a platform that enables innovators to build and scale AI with confidence. As a Senior Software Engineer, you will lead the design and delivery of foundational platform services for Agentic Developer Workflows and AI Tools Management, while mentoring junior engineers and establishing operational standards.

Responsibilities

• Architect, build, and operate the MCP hosting platform and the MCP Registry with strong lifecycle, versioning and governance semantics. Provide templates, SDKs, and reference implementations for internal teams
• Lead end-to-end design for agentic experiences (inner loop assistants, post-PR integration agents, release/incident copilots), ensuring reproducibility, explainability, and safe autonomy configuration
• Drive spec-driven development patterns across the platform: make specs first-class, build structured retrieval and test generation pipelines, and ensure agent outputs are validated automatically against specs and policy gates
• Define and enforce operational guardrails: human-in-the-loop by default, policy enforcement gates (static analysis, vulnerability checks), observability, audit trails, and drift detection. Ensure agents cannot perform forbidden or unsafe autonomous behaviors without explicit configuration
• Build the AI Tools Management Control Plane capabilities (usage/spend tracking, policy engines, agentic optimization), and integrate telemetry/dashboards for visibility and automated decisioning. Optionally lead pilots that surface ROI and spend savings
• Collaborate cross-functionally with DevEx, SRE, Security, Product, and teams exposing MCP servers; influence roadmap and take ownership of complex initiatives. Mentor engineers, lead design reviews, and drive high quality delivery

Skills

• 6+ years experience building and operating distributed systems, platform services, or developer infrastructure
• Track record designing and shipping production APIs, services, and platform components at scale
• Strong systems programming skills (Go preferred) and deep experience with Kubernetes, container runtime concerns, IaC, and CI/CD best practices
• Experience building developer-facing tools or infrastructure (preview environments, CW-CLI style tooling, CI/CD integrations)
• Demonstrated ability to drive cross-team initiatives and provide technical leadership
• Significant experience designing MCP-style tool integrations, registries, or SDKs for machine consumption and tool discovery
• Experience building agentic or autonomous systems with safety controls, explainability, and human-in-the-loop design
• Experience with knowledge/context systems (semantic indexes, RAG pipelines, Sourcegraph, vector stores), and building test/validation pipelines for generated code
• Experience creating operational tooling for usage/spend analytics and building dashboards (Grafana, Prometheus) and agentic automation for policy enforcement
