Senior Machine Learning Engineer (Inference Platform)

Remote - USA

About Wizard AI

At Wizard AI, we’re building a high-performing AI Shopping Agent that helps people discover the best products across the web with speed, accuracy, and trust. Our ML systems sit at the core of that experience, and we’re looking for a Senior MLOps Engineer to help us run them reliably and efficiently in production.

The Role

As a Senior MLOps Engineer at Wizard, you’ll own the end-to-end lifecycle of our ML systems — from packaging and deployment to monitoring, performance, and scaling — across a custom-built inference platform powering a live conversational product.

This isn’t a typical “pipeline” role. Our platform runs multiple specialized inference engines (LLMs, embeddings, and extraction models), each with different performance and scaling characteristics. A big part of the role is thinking through tradeoffs — latency vs. cost, throughput vs. reliability — and helping us evolve the system as we grow.

You’ll work closely with ML, Data, and DevOps, and have real input into how the platform is designed — not just how it’s maintained.

What You’ll Do

  • Build and improve production ML pipelines, making it easy to move models from experimentation to reliable production use
  • Help own and evolve our multi-engine inference platform (LLMs, embeddings, and extraction), improving how different workloads are served and scaled
  • Put strong foundations in place for model versioning, rollouts, and rollbacks so systems stay reproducible and safe to iterate on
  • Define and monitor key system metrics like latency, availability, and GPU utilization, and set clear expectations around performance
  • Improve overall system performance — whether that’s reducing latency, increasing throughput, or making better use of GPU resources
  • Design systems that are resilient and cost-aware, with thoughtful approaches to autoscaling, failure isolation, and graceful degradation
  • Bring solid engineering practices (testing, CI/CD, observability) into ML workflows to help the team move faster without sacrificing reliability
  • Partner closely with ML, Data, Product, and DevOps to turn ideas into production-ready systems and help guide technical decisions

What We’re Looking For

  • 5–8+ years of experience in software, ML, platform, or infrastructure engineering, with hands-on ownership of production ML systems
  • Experience deploying and running LLMs or other deep learning models in real-world environments
  • Strong Python skills and a solid foundation in software engineering
  • Familiarity with cloud platforms (AWS, GCP, Azure) and common ML tooling (model registries, experiment tracking, etc.)
  • A good understanding of inference performance — batching, memory usage, quantization, and how systems behave across CPU and GPU
  • Experience working with (or curiosity about) systems that serve different types of models with different constraints
  • Ability to think through tradeoffs between speed, cost, and reliability in a practical way
  • Comfort working in a fast-moving environment where things evolve quickly

What Success Looks Like

Reliable, Scalable Systems
Our ML systems run smoothly with clear visibility into performance, and can scale as demand grows without constant firefighting.

End-to-End Ownership
You’re able to take a model from idea to production and keep it running well, while making it easier for others to do the same.

Real Impact
You help shape how our ML platform evolves — improving performance, reducing costs, and making the overall system stronger over time.

Compensation & Benefits

The expected base salary range for this role is $200,000 – $250,000 USD, and will vary based on skills, experience, role level, and geographic location. Final compensation will be determined by considering these factors alongside overall role scope and responsibilities.

In addition to base salary, Wizard offers:

  • Equity in the form of stock options
  • Medical, dental, and vision coverage
  • 401(k) plan
  • Flexible PTO and company holidays
  • Fully remote work within the United States
  • Periodic company offsites and team gatherings

Wizard is committed to fair, transparent, and competitive compensation practices.

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
