The role

Reporting to the Senior Engineering Manager for ML Workflows, this Senior Software Engineer will own the architecture and evolution of core systems in the Weights & Biases platform.

ML Workflows owns what customers use to move models and data through W&B. Artifacts is the versioned data layer that every object logged to W&B runs through. Registry sits on top of it as the organization-wide source of truth for what is production-ready, and it is used by teams at Pinterest, Dropbox, and Canva. Automations is the event and action layer the rest of the platform builds on. Launch is execution infrastructure that runs customer ML and agent workloads.

The role

Reporting to the Senior Engineering Manager for ML Workflows, this Senior Software Engineer will own the architecture and evolution of core systems in the Weights & Biases platform.

We expect all of these

Bachelor’s degree or foreign equivalent in Computer Science, Computer Engineering, Data Science, Information Systems, or a closely related technical or quantitative field involving substantial coursework in Engineering.
6+ years of software engineering experience, including time leading significant technical initiatives or architectural changes
Strong proficiency in Go, or in another compiled language (C, C++, C#, Rust, Java) with the ability to ramp on Go quickly
Working proficiency in Python
Comfort diving into complex systems you did not write, to diagnose and fix difficult bugs across service boundaries
A track record of mentoring engineers and raising the technical bar around you
Strong communication, including the ability to explain complex technical decisions to different audiences

And real depth in at least one or two of these, which is also how we work out which team you join:

Distributed systems and infrastructure. Designing and operating services in production, containers and Kubernetes, cloud infrastructure, orchestration.
Frontend and full-stack. TypeScript and React, complex state management, frontend performance work, taking a feature all the way through to the UI.
Data at scale. Schema design, query performance, large-scale storage, and analytical stores such as ClickHouse.
APIs and developer surfaces. API design, GraphQL query optimization and data fetching strategies, SDKs and client libraries.
Event-driven systems. Message queues such as Kafka or PubSub, delivery semantics, idempotency, and retries.

We do not expect one person to have all of this. Depth in a couple of these areas and the range to work outside them is what we are after. Experience in ML infrastructure, MLOps, or developer tools is a plus.

The base pay and target total cash for this position range from $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)
