About ShyftLabs
At ShyftLabs, we live and breathe data. Since 2020, we've been helping Fortune 500 companies unlock growth with cutting-edge digital solutions that transform industries and create measurable business impact. We're scaling globally with entities in Canada, the U.S., and India and we're looking for passionate problem-solvers who are ready to turn big ideas into real outcomes.
The Opportunity
ShyftLabs is looking for a Senior AI Engineer to sit at the intersection of AI/ML engineering and backend platform development. This isn't a research role, it's a hands-on engineering position where you'll design, build, and ship AI-powered features directly into production systems. You'll work closely with Product, Architecture, and cross-functional engineering teams to integrate intelligent capabilities into our next generation of data-driven platforms, while also contributing to the scalable backend infrastructure that powers them.
The ideal candidate combines deep AI/ML engineering experience with strong backend development skills, someone equally comfortable fine-tuning an LLM integration as they are designing a robust API or event-driven service.
What You'll Do
-
Architect and implement AI-powered features end-to-end, from model integration and prompt engineering to deployment, monitoring, and iteration
-
Integrate LLM APIs, ML models, and intelligent automation pipelines into scalable, production-grade backend systems
-
Fine-tune and optimize models for performance, reliability, and cost efficiency in live environments
-
Design and build robust APIs, event-driven services, and third-party integrations that support AI-enabled workflows
-
Collaborate with Product to translate business requirements into technical AI solutions, defining scope, complexity, and dependencies
-
Build and maintain data pipelines and MLOps workflows to support model deployment and lifecycle management
-
Contribute to system architecture decisions, integration patterns, and reusable AI frameworks across the platform
-
Partner with data scientists and engineers to ensure smooth, scalable model deployments
-
Produce clear technical documentation, architecture diagrams, data flows, API specs, and AI integration patterns
-
Lead code reviews, enforce best practices in code quality and testing, and mentor engineers across teams
-
Troubleshoot complex production issues across distributed and AI-integrated systems
-
Stay ahead of industry trends in AI/ML tooling, frameworks, and practices
What You Bring
-
5+ years of experience building scalable, production-grade software systems
-
2+ years of hands-on AI/ML engineering experience, including deploying models into production environments
-
Bachelor's degree in Computer Science, Data Science, AI, or a related field
-
Strong expertise in Python, with hands-on experience using frameworks such as TensorFlow, PyTorch, or Scikit-learn
-
Solid backend engineering background, API development, microservices, distributed systems, and event-driven architectures
-
Experience integrating LLM APIs and building AI-driven features into web or platform applications
-
Strong proficiency in JavaScript/TypeScript and Node.js, with exposure to GraphQL
-
Deep experience building and consuming RESTful APIs and distributed services
-
Proficiency with SQL and hands-on experience with cloud platforms, GCP or AWS (e.g., S3, Lambda, RDS, EC2)
-
Familiarity with MLOps best practices and tools for model monitoring, versioning, and deployment
-
Strong understanding of software design patterns, system architecture, and data flow design
-
Excellent communication skills with the ability to articulate complex technical concepts clearly
-
Experience working in Agile/Kanban environments with a strong grasp of the full SDLC
Nice to Have
-
Experience with data platforms, analytics systems, or ETL pipelines
-
Familiarity with real-time data processing and messaging systems such as Kafka or SQS
-
Exposure to tax, fintech, or compliance-related product development
-
Experience designing multi-tenant or enterprise-grade SaaS platforms
-
Background in integration-heavy environments such as ERP, financial systems, or external data providers
Salary Range
- $120,000 - $160,000 (CAD)
