Senior Software Engineer, Infrastructure Operations - Weights & Biases

About the role

The Infra Ops team is a new team in the Execute pillar of Weights & Biases infrastructure. Our mission is to keep our platform engineers building: we absorb, reroute, and automate incoming infrastructure requests — incidents, how-to questions, troubleshooting requests, and one-off asks — so that other pillars can focus on their deliverables.

Responsibilities

• Triage and resolve incoming infrastructure requests across Slack, Jira, and office hours — resolving well-scoped ones yourself and escalating others with a clear, reproducible hand-off.
• Troubleshoot problems across the stack — dig through logs, systems, and configuration to work out what is actually happening, asking for help when a problem runs deep.
• Write scripts and other automation in Python, Bash, and Go that reduce repetitive work.
• Help maintain and improve build and release pipelines, along with the runbooks and self-service docs the team depends on.
• Partner and collaborate closely with our SA, security, and product engineers on one side, and with the other infra pillars on the other.
• Document recurring how-to and configuration questions so they can be answered once and reused.

Requirements

We are seeking an Infrastructure Operations Engineer to be part of the first line of support for the infrastructure org. This is a support-oriented, interrupt-driven role: your days are shaped by incoming requests from our internal customers — Solutions Engineers, security, compliance, and product developers on other teams — rather than by a single long-running project.

Qualifications

• Experience: 2+ years in an infrastructure, SRE, operations, DevOps, or technical-support role — or equivalent experience from a computer-science (or related) degree, a bootcamp, or substantial personal/open-source projects.
• Scripting: Comfortable scripting in at least one of Python, Bash, or Go, and eager to use code to eliminate repetitive work.
• Systems foundation: Experience with Linux, containers, and at least one major public cloud (GCP, AWS, or Azure); infrastructure-as-code (Terraform) is a must.
• Able to drive well-scoped problems to resolution, and to recognize when to pull in a more senior teammate.
• Strong written and verbal communication and a service mindset — you communicate effectively with our internal customers.
• A genuine desire to help people and unblock them — you take satisfaction in solving someone else's problem, not just your own.
• Patience and composure under pressure, with the ability to stay positive and constructive.
• Comfortable with a support-driven, high-context-switching, and sometimes repetitive workload — you can hold several small threads at once without losing the plot, and you drive the automation of recurring patterns.
• Aim to make yourself unnecessary — automate everything to free time for larger infrastructure projects at the edges of other infrastructure pillars.

Skills

• Experience with CI/CD systems (GitHub Actions, Argo, or similar) and observability tooling (Datadog).
• Hands-on experience designing, building, and maintaining complex, production-grade AI agents — including continuous multi-source data ingestion and indexing, and RAG / context augmentation.
• Hands-on experience with production databases (PostgreSQL, ClickHouse, or similar).
• Prior internship or role on a platform, developer-experience, or support-engineering team.

Benefits

• Medical, dental, and vision insurance - 100% paid for by CoreWeave
• Company-paid Life Insurance
• Voluntary supplemental life insurance
• Short and long-term disability insurance
• Flexible Spending Account
• Health Savings Account
• Tuition Reimbursement
• Ability to Participate in Employee Stock Purchase Program (ESPP)
• Mental Wellness Benefits through Spring Health
• Family-Forming support provided by Carrot
• Paid Parental Leave
• Flexible, full-service childcare support with Kinside
• 401(k) with a generous employer match
• Flexible PTO
• Catered lunch each day in our office and data center locations
• A casual work environment
• A work culture focused on innovative disruption
