Job title: Machine Learning Engineer - Ads

Shopify

Great advertising connects merchants with customers who genuinely need what they're selling. As a Machine Learning Engineer focused on Ads, you'll build the targeting and personalization technology that makes these meaningful connections happen at scale. You'll develop sophisticated machine learning models that help merchants reach the right audience at exactly the right moment, creating advertising experiences that drive real business growth while respecting the customer experience.

Key Responsibilities

• Develop and optimize advanced machine learning models for ad targeting and personalization systems
• Analyze comprehensive ad performance data to identify optimization opportunities and maximize ad spend efficiency
• Collaborate closely with advertising teams to integrate ML solutions seamlessly into our ad platform
• Research and implement innovative algorithms and tools to enhance ad relevance and effectiveness
• Document technical insights and share best practices across engineering teams

Qualifications

• Extensive experience building and deploying machine learning models for advertising systems at scale

• Strong proficiency in ML frameworks including TensorFlow or PyTorch, with expert-level Python programming skills

• Proven analytical skills for processing and extracting insights from large-scale datasets

• Demonstrated problem-solving abilities and innovative thinking in ad technology solutions

• Solid familiarity with ad platforms, A/B testing methodologies, and data-driven decision making processes

• Experience with statistical methods and performance optimization for ML systems

• Ready to connect merchants with their perfect customers? Join the team that's making commerce better for everyone.

• This role may require on-call work

• About the discipline

• Engineering. It’s our DNA.

• Engineering isn't a department at Shopify. It's our DNA. The engineers who thrive here care about the code, the system, and the merchants relying on both. They want hard problems and uncomfortable growth. They find solutions without waiting for permission. They ship weekly. They want commerce to work better for everyone. So does our founder, Tobi, who still codes and still shapes where this thing is going.

• They're open source nerds. They pair program because two brains write better code than one. New tools, new models, new approaches. They experiment constantly. Most of what's standard here started as someone hacking on something.

• They use AI like a keyboard, reflexively and everywhere, to clear the mundane and make room for thinking. And they work in the open. The fastest way to learn here is to watch someone better than you do the work. If that sounds like you, come build with us.

• Infrastructure engineering

• Infrastructure Engineers at Shopify build and maintain the systems that handle millions of requests per second and billions of dollars in transactions. At that scale, performance gains matter and weak assumptions surface quickly. Your systems power the experience for millions of entrepreneurs and buyers every minute of every day, including peak events like Black Friday.

• Engineers at Shopify spend the majority of their time actually writing code to build and improve infrastructure. You’ll solve problems that don’t exist anywhere else, with challenges that push what’s possible. If that lights you up, come build with us.

• Growth and rewards

• Mastery-matched compensation.

• At Shopify, getting better at your craft and increasing your impact is how you grow. Twice a year, we assess both in our Mastery cycle, Shopify’s performance review. Achieving higher Mastery is a promotion, and when you earn a promotion your total rewards grow with it. Crafter and manager are equal paths, so you can pursue excellence in the craft you’re best at.

• Total Rewards

• With Flex Comp, your Rewards Wallet gives you agency over your compensation mix. Adjust your mix of cash, restricted share units, and stock options (including programs like Long-Term Equity)* to where it makes sense for you, and mix it up anytime as life and priorities change. Buying a house? Want more skin in the game? Just experimenting? It’s your call.

• Flex Comp program offerings vary based on location, role, and employment type. Full details are set out in our Terms & Conditions and related plan documents.

• Built for real life

• Room for the rest of your life.

• Flexible work, remote by design

• A flexible vacation policy means most Shopifolk can take the vacation days they feel they need to recharge.

• If a change of everyday scenery is more your jam, Destination 90 means you can work from (almost) anywhere in the world for 90 days of the year.

• Your setup

• Your battlestation is your home base. Request the desk, chair, and AV gear you need to get shit done.

Benefits

• You need ‘em, we’ve got ‘em. Our health and welfare benefits may include health, dental, vision, disability, and life insurance depending on your country. If you’re in a country without a package, you'll receive a monthly allowance. We also offer mental health support for you and your dependents, including immediate and confidential services like counseling and coaching sessions.

• Family support

• We offer fertility benefits globally, along with paid parental leave to welcome a new family member.
