We are Baseten, the team that powers mission-critical inference for the world’s most dynamic AI companies such as Cursor, Notion, OpenEvidence, Abridge, Clay, Gamma and Writer. We’re growing quickly and recently raised our $300M Series E, backed by investors including BOND, IVP, Spark Capital, Greylock and Conviction.

Apply Here: https://jobs.ashbyhq.com/baseten?utm_source=gkzEP29VD4 or email Jason.dupree@baseten.co

We are hiring for multiple core roles:

1. Solution Architect: You will partner closely with sales and customers to translate business needs into technical solutions, run technical discovery, and guide repeatable deployments and proofs of value for customers. This role is a great fit for entrepreneurial, customer-facing technical professionals who want a front-row view into how modern companies adopt AI at scale, and who enjoy working across technical discovery, solution design, demos, deployment scoping, and hands-on customer implementations, in close partnerships with Sales and Engineering

2. AI Solutions Engineer/Forward Deployed Engineer: You will partner directly with customers to architect, build, and deploy high-scale production AI applications on Baseten’s platform. You’ll own the journey with customers from initial exploration to production deployment. To be clear, this is a technical engineering role with hands-on coding and software dev that also includes aspects of product management, technical customer success and pre-sales solutions engineering mixed in. We’re language agnostic but strong Python and ML experience is a big plus.

3.

This role blends deep infrastructure debugging, AI/ML performance expertise, incident command, and proactive account ownership. You'll triage and resolve issues across Kubernetes, GPUs, networking, and model serving, lead war rooms during P0 escalations, and translate recurring pain points into product improvements.

The Offer:

Compensation: Very competitive, we’re looking for folks with a breadth of experience

Equity: This is an opportunity to participate in the ownership of a fast-growing AI Infrastructure platform

Location: We are based out of San Francisco with offices in New York. We are also open to remote employees for these roles.
