Staff Machine Learning Engineer

Scientific Games; Montreal (administrative region); On-site; CAD 120,000 - 180,000; Full time

Job summary

Scientific Games is seeking a Staff Machine Learning Engineer to define and build the ML platform architecture. You will establish architectural foundations, reusable tooling, and a platform roadmap to accelerate Data Scientists’ velocity with reliable self-service workflows.

The role focuses on designing end-to-end platform primitives for batch/inference, deployment, and observability, while mentoring engineers and partnering with DS leadership to scale the platform globally.

Qualifications

• 5+ years of hands-on experience in ML engineering or large-scale production ML systems.
• Experience designing platform architecture and reusable ML tooling standards.
• Experience building self-service internal platforms and deployment frameworks.
• Strong experience enabling Data Science teams through reusable infrastructure.
• Leading architecture decisions and mentoring engineers.

Responsibilities

• Define target architecture and phased roadmap for the first ML platform.
• Build self-service deployment frameworks enabling DS to productionize models independently.
• Architect reusable capabilities: model registry, deployment orchestration, feature retrieval, inference routing, observability, rollback.
• Establish platform engineering standards across SDKs, templates, CI/CD, IaC, and developer workflows.
• Mentor Senior MLEs and raise software engineering quality and platform thinking.

Job description

Scientific Games:Scientific Games is the global leader in lottery games, sports betting and technology, and the partner of choice for government lotteries. From cutting-edge backend systems to exciting entertainment experiences and trailblazing retail and digital solutions, we elevate play every day. We push game designs to the next level and are pioneers in data analytics and iLottery. Built on a foundation of trusted partnerships, Scientific Games combines relentless innovation, legendary performance, and unwavering security to responsibly propel the global lottery industry ever forward.Position SummaryAbout the RoleWe are looking for a Staff Machine Learning Engineer to define and build the machine learning platform architecture for the organization. This team will create the enabling layer that allows Data Scientists to self-serve deployment, experimentation, batch scoring, online inference, monitoring, and safe rollout workflows .This is a platform creation role, not a platform operations gatekeeper role . The success metric is not how many deployments the team executes directly, but how effectively the platform allows domain Data Scientists to deploy independently through highly reliable self-service workflows. The initial Staff MLE hires will establish the architectural foundations, engineering standards, reusable tooling strategy, and platform roadmap that the Senior MLE team will scale.This role is based out of Toronto.QualificationsKey ResponsibilitiesDefine the target architecture and phased roadmap for the organization’s first ML platformBuild self-service deployment frameworks enabling Data Scientists to productionize models independentlyArchitect reusable capabilities for model registry, deployment orchestration, feature retrieval, inference routing, observability, and rollbackDefine golden paths for batch inference, real-time serving, shadow deployment, canary rollout, A/B testing, and full production releaseEstablish platform engineering standards across SDKs, templates, CI/CD, testing, infrastructure-as-code, and developer workflowsDesign platform primitives that support recommendation systems, forecasting, optimization, and experimentation use casesMentor Senior MLEs and raise software engineering quality, architecture rigor, and platform thinking across the teamPartner with Data Science leadership to ensure the platform accelerates DS velocity rather than introducing process frictionRequired QualificationsEducationMaster’s degree in Computer Science, Engineering, Distributed Systems, Machine Learning, or another related STEM fieldBachelor’s degree with exceptional relevant platform engineering depth is acceptableExperience5+ years of hands-on experience in ML engineering, platform engineering, or large-scale production ML systemsProven experience designing platform architecture and reusable ML tooling standardsExperience building self-service internal platforms, developer tooling, or ML deployment frameworksStrong experience enabling applied Data Science teams through reusable infrastructure rather than centralized service modelsExperience leading architecture decisions and mentoring engineersTechnical SkillsDeep expertise in ML systems architecture across batch and low-latency real-time servingStrong hands-on experience with Docker, Kubernetes, infrastructure automation, and cloud-native ML workloadsStrong expertise in model lifecycle tooling including MLFlow, registries, validation gates, and promotion workflowsAdvanced experience designing CI/CD, canary, rollback, and deployment safety systems for MLExperience with feature stores, online/offline feature parity, and low-latency feature retrievalStrong Python engineering standards and ability to write production-grade frameworks and SDKsLeadershipDemonstrated ability to define technical direction for platform teamsStrong mentorship track record for Senior and mid-level MLEsStrong cross-functional influence with DS, data platform, and product engineering teamsBias toward building self-service systems that maximize organizational leveragePreferred QualificationsExperience building greenfield ML platforms from zero to scaled enterprise adoptionExperience supporting self-service recommendation, ranking, forecasting, and optimization systemsFamiliarity with Databricks, Azure ML, SageMaker, Vertex AI, or equivalent ML platformsExperience building internal developer portals, CLIs, or workflow SDKsStrong platform product thinking focused on usability, adoption, and DS productivitSG is an Equal Opportunity Employer and does not discriminate against applicants due to race, color, sex, age, national origin, religion, sexual orientation, gender identity, status as a veteran, and basis of disability or any other federal, state or local protected class.
