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

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.

Qualifications

Preferred Exposure to CI/CD systems (GitHub Actions, Argo, or similar) and observability tooling (Datadog).

Applied AI: 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.
