Salary:

225000.00 - 325000.00 USD / Year

Antimetal

Expiration Date

Until further notice

Requirements

At least 3 years of experience in ML platform engineering, data engineering, or a related role, preferably at a high-growth company
Prior experience designing evaluation systems where ground truth is noisy, high-volume, and hard to label (e.g. computer vision, deep research pipelines)
Strong system design skills: you think about how data flows through distributed systems and how decisions compound at scale
Proven ability to write clean, scalable code and strong data modeling skills
Demonstrated ability to bring ambiguous goals from prototype to production, using data and experimentation to drive product and architectural decisions
Proficient in Python and Typescript, with experience using common ML libraries and data engineering tools

Job Responsibility

Own the evaluation stack: Build online and offline eval pipelines that measure agent quality across ephemeral, voluminous MELT data, code, and unstructured docs. Set the metrics that define the experience
Define quality at scale: Production incidents span hundreds of services–ephemeral, high-volume, and where ground truth is approximative. Design evals that capture trajectory quality, not just final outputs, and validate that your metrics predict real outcomes
Build platform abstractions for agents: Design core agent architectures and extend internal frameworks (e.g. sub-agents, MCPs, middleware) – that lets product, platform, and research iterate with confidence and ship faster
Productionize: Own latency, observability, and uptime

What we offer

Pay & ownership — Competitive salary with generous equity grants
Full coverage + retirement — Fully covered health, dental, and vision, plus retirement benefits
Unlimited PTO — Take the time you need to recharge
Dinner on late nights — Working late? Dinner is on us
Fitness stipend — Monthly support for your health and wellness
Tools of the trade — Any equipment you need to do your best work
