Role summary

MaintainX is seeking a Senior Product Data Scientist to join their Product Analytics team. This role will define rigorous experimentation and ML-driven insights, directly influencing product evolution. Responsibilities include designing and leading product experimentation programs (A/B tests, causal inference), building and deploying ML models (GBMs, random forests, logistic regression), partnering with Product, Design, and Engineering, and translating complex findings into clear business narratives for senior stakeholders. The ideal candidate has 5-7 years of relevant experience in B2B/B2C SaaS, proficiency in Python with scikit-learn and MLflow, and strong cross-functional and executive communication skills.

About MaintainX

MaintainX is the world's leading mobile-first work execution platform for industrial and frontline teams. We help over 13,000 customers — including Duracell, McDonald's, Shell, DHL, and Volvo — reduce unplanned downtime and run more efficient operations.

In July 2025 we closed a $150M Series D led by Bessemer Venture Partners, bringing our total funding to $254M at a $2.5B valuation. We were named to the 2025 Forbes Cloud 100 and ranked #1 in EAM and CMMS on G2's Summer 2025 report.

The market we serve is changing fast: 68% of industrial companies have the same or more downtime than they did in 2024, and there are 3.8M unfilled manufacturing jobs projected through 2033. Our work matters because real plants, real machines, and real frontline workers depend on it.

The Role

We're hiring a Senior Product Data Scientist to join our Product Analytics team. You'll be the first dedicated Data Scientist on a team that has operated as a product analytics function — meaning you'll define what rigorous experimentation and ML-driven insight looks like at MaintainX, and directly influence how our product evolves.

Design and lead product experimentation programs (A/B tests, causal inference) that drive measurable improvements in product adoption and retention

Build and deploy ML models — GBMs, random forests, logistic regression — that turn product signals into actionable decisions for PMs and engineering leads

Partner cross-functionally with Product, Design, and Engineering to frame business problems as data problems and translate findings into decisions

Translate model outputs and experimental results into clear business narratives for senior stakeholders and executives

Establish best practices for experimentation and ML workflows

You Have

Must-haves:

Senior Product Data Scientist or Senior Data Scientist title with 5–7 years of relevant experience

Hands-on experience with product experimentation — A/B testing, causal inference, statistical significance

Python proficiency including scikit-learn and MLflow

Experience building ML models (GBMs, random forest, linear/logistic regression)

Background in B2B SaaS or B2C SaaS

Strong cross-functional communication — you've worked directly with PMs, engineers, and designers, not just a sales or finance audience

Executive presence: you can turn a complex model output into a business recommendation a VP can act on

Nice-to-haves:

Experience with Databricks

Familiarity with Amplitude or similar event analytics platforms

We Offer

Competitive base + equity in a high-growth, post-Series D company

Day-1 benefits coverage — health, dental, vision

Unlimited PTO

$500 home office stipend · $1K annual L&D budget

Hybrid hubs in Montreal, Toronto, Raleigh, Miami, and Bay Area

How We Work

We reward output. We promote quickly when people deliver, and we have honest conversations early when fit isn't right. If you're energized by ambiguity, care about the people our platform serves, and want to do the most impactful data science work of your career — we'd love to talk.
