Original job description

Senior Machine Learning Developer

Location: Montreal, Quebec, Toronto, or Ontario

About Numa

Numa is building the platform to power AI-native dealerships, rearchitecting automotive service and sales with advanced AI agents that automate customer interactions, streamline operations, and reimagine how dealerships work. Numa integrates AI into every aspect of dealership functions - from rescuing customer calls and voicemails that generate more revenue, to reducing customer resolution times that drive overall customer satisfaction (CSI), to improving dealership team productivity and accountability. Numa has raised $50 million from leading investors (Google, Threshold, Costanoa, Mitsui, and Touring Capital).

The Role

We’re hiring a Senior Machine Learning Developer to build and ship ML/AI systems that interact with real customers thousands of times a day. Our voice agents book service appointments, rescue missed calls, and route callers through natural conversations. You’ll work across products and platforms. You’ll ship AI features including prompts, agents, tools, and production ML models, while building the evaluations and tooling that help teams ship with confidence. You’ll also contribute to our ML platform, including model serving, LLM infrastructure, and production observability. At Numa, we believe great ML is about more than building bigger models. It’s about knowing whether a change is good enough to ship. Our evaluation-first approach makes that measurable in CI and production.

What You’ll Do

Build conversational AI systems for phone and SMS that understand customer needs, take action, and know when to act autonomously
Develop tooling such as memory, knowledge graphs, and validated customization that help agents reason and adapt to dealership needs
Train, evaluate, and deploy ML models using Ray Serve and Dagster for prediction, classification, ranking, and capacity forecasting, and keep them healthy in production
Create offline and online evaluations, simulations, and CI gates that catch regressions and continuously measure quality in production
Implement shared evaluation, observability, and LLM tooling that helps product squads ship faster and more reliably
Raise the engineering bar through design and code reviews, technical writing, and mentorship
Work autonomously when goals are clear and help create clarity when they are not

What You Bring

6+ years of software or machine learning engineering experience, with a track record of shipping ML or LLM powered systems to production
Strong Python and solid software engineering fundamentals; you write code others can build on, test, and trust
Hands-on experience building AI systems; training and deploying ML models (prediction, classification, ranking) and/or working with LLMs (prompting, tool use, agents, retrieval) with a real intuition for where they break
A rigorous, evaluation-first instinct, you reach for measurement to tell a real improvement from a lucky one, and a real regression from noise
Comfort operating with meaningful ambiguity in a product environment, and the judgment to know where to invest depth versus speed
Ownership and communication; you can carry a piece of work from problem framing through shipped, monitored, and improved

Nice To Have

Experience building or operating ML platform and tooling: evaluation frameworks, model serving, feature/prompt registries, or ML observability
Familiarity with our stack or its neighbors: LiveKit, Ray Serve, Dagster, Vertex AI, GCP, Kubernetes, Pulumi, or provider APIs (Anthropic, OpenAI, Deepgram, ElevenLabs)
Comfortable taking a model or agent from prototype to production and owning it there
Proficient with real-time or streaming systems: voice, telephony (SIP/WebRTC), or low-latency inference
Familiarity working in a startup or high-growth environment with evolving conditions

What Success Looks Like

Your squad ships AI features faster and with more confidence because the evals and tooling around them are solid
No AI change you own reaches customers without an evaluation standing behind it and regressions are caught before they ship
You've turned at least one hard-won squad lesson into platform leverage the rest of the team now relies on
Production issues in your area are understood, measured, and closed with statistical confidence that the fix actually worked
Other engineers are better at building AI systems because of your reviews, your writing, and how you work

Why Join Numa

We believe in everyone's growth
Be part of an industry leader named the #1 fastest-growing AI Automotive company by Inc. 5000
Represent category-defining AI technology that is transforming the automotive industry
Join a high-growth organization with significant opportunities for career advancement

Compensation & Benefits

Base Salary Range: $200,000 - $250,000 CAD
Equity Packages
Flexible PTO
Fully Covered Group Insurance

At Numa, you’ll have the chance to represent game-changing technology in an industry that’s ready for innovation. If you love being in the field, thrive on solving problems in real time, and want to make an impact at a high-growth company, we’d love to hear from you.
