Job Level
About the role
- Design and build transformative ML systems – Lead the development of advanced generative AI solutions, agentic workflows, RAG architectures, and intelligent platforms using PyTorch, modern ML frameworks, and large language models; write production-quality code that scales and performs
- Drive AI innovation through hands-on technical work – Experiment with frontier models, implement novel ML architectures, evaluate emerging AI technologies, build proofs-of-concept, and translate cutting-edge research into production capabilities that deliver real business value
- Lead projects and drive technical excellence – Take ownership of significant ML initiatives from design through deployment; make architectural decisions, establish coding standards, implement robust CI/CD for ML systems, and ensure solutions are both innovative and reliable
- Mentor and elevate junior engineers – Provide technical guidance, conduct code reviews, share ML best practices, and help junior team members grow their skills; foster a culture of learning, experimentation, and technical excellence
- Build production ML infrastructure – Develop scalable APIs (FastAPI, etc.) for model deployment, implement MLOps pipelines, leverage cloud platforms (AWS/Azure) to optimize AI infrastructure, and use orchestration tools (Airflow) for complex ML workflows
- Champion ML governance and operational excellence – Ensure adherence to AI/ML governance guidelines, monitor model performance and SLAs, optimize systems for reliability and cost-effectiveness, and implement best practices for production ML systems
- Collaborate across teams effectively – Partner with product squads, business stakeholders, and cross-functional teams to integrate ML solutions into flagship products and workflows; translate complex ML concepts for diverse audiences; and ensure seamless transitions from prototype to production
- Stay at the bleeding edge – Continuously explore emerging ML technologies, attend conferences, contribute insights from research, and bring innovative approaches back to the team; help shape our technical strategy through your expertise and experimentation
Requirements
- Strong ML engineering expertise – 6+ years of professional experience building production AI/ML systems, with demonstrated ability to deliver advanced generative AI and ML solutions from concept through deployment
- Advanced generative AI and LLM experience – Extensive hands-on experience developing and integrating generative AI solutions, working with large language models, building agentic workflows, implementing RAG architectures, and integrating AI capabilities into existing products and systems
- Deep ML technical skills – Strong proficiency in Python and ML algorithms ranging from classical techniques to deep learning; proven experience training, fine-tuning, and deploying neural network models using PyTorch with focus on performance optimization and scalability
- Bachelor's degree in Machine Learning, Computer Science, Data Science, Applied Mathematics, or related field (Master's or PhD is strongly preferred)
- Production ML engineering excellence – Strong understanding of MLOps, containerization (Docker, Kubernetes/AWS EKS), cloud platforms (AWS/Azure including Bedrock, SageMaker, Azure AI Search), workflow orchestration (Airflow), and API development for ML systems
- Software development fundamentals – Deep understanding of automated testing, source version control, code optimization, software architecture, and building scalable, maintainable systems
- Technical leadership through influence – Track record of leading project initiatives, mentoring team members, shaping technical strategy without direct management, and driving innovation in fast-paced environments
- Outstanding collaboration and communication – Ability to work effectively with technical and non-technical stakeholders, translate complex ML concepts for diverse audiences, and foster alignment across distributed cross-functional teams.
Benefits
- Build breakthrough ML systems with real impact – Design and ship production generative AI platforms, multi-agent systems, and intelligent automation that will process billions in credit decisions; work on problems at the frontier of applied AI while seeing your work directly change how analysts and financial markets operate
- Work at the cutting edge of ML technology – Experiment with the latest LLMs and foundation models, implement novel RAG architectures, build agentic systems, fine-tune neural networks, and leverage enterprise-scale GPU clusters and cloud infrastructure; substantial conference and training budgets to stay at the forefront
- Technical leadership without the bureaucracy – Lead projects, mentor junior engineers, shape technical direction, and influence architectural decisions through your expertise and results—not through management hierarchy; your ideas and code will define how we build AI systems
- Toronto's world-class AI ecosystem – Work in one of the world's premier AI research hubs alongside Vector Institute researchers, attend cutting-edge ML meetups and conferences, and be part of the community defining the future of applied AI and machine learning
- Greenfield innovation with enterprise backing – Build net-new ML systems from scratch with the freedom to experiment boldly, fail fast, and push boundaries—backed by the compute resources, research budgets, and organizational support that most startups can only dream of
- Solve sophisticated ML challenges – Tackle hard problems at the intersection of NLP, document intelligence, reasoning systems, agentic workflows, and production-scale deployment; work on challenges that will expand your expertise and push your technical boundaries
- Clear growth trajectory – High visibility to senior leadership, mentorship from experienced ML architects, and clear paths to Lead ML Engineer or Principal ML Engineer roles; build a reputation as a go-to expert in generative AI and financial technology
