About the Role

We are looking for a Sr. Software Developer, GenAI with a strong software engineering background and deep expertise in Generative AI to join our team. In this role, you will build retrieval-augmented generation (RAG) systems with techniques such as vector search, hybrid retrieval, knowledge graphs, re-ranking, document chunking, embedding, and long-term memory, using AI developer frameworks and technologies such as Azure AI Search, Neo4j, and Azure Cosmos DB.

What you’ll do:

• Design and build multi-agent systems that plan, delegate, and reason to achieve complex objectives, using frameworks such as LangChain, LangGraph, and Azure AI Foundry.
• Build retrieval-augmented generation (RAG) systems with techniques such as vector search, hybrid retrieval, knowledge graphs, re-ranking, document chunking, embedding, and long-term memory, using AI developer frameworks and technologies such as Azure AI Search, Neo4j, and MongoDB.
• Implement observability, evaluation, monitoring, and guardrails to maximize performance, quality, security, and robustness in Gen AI applications. These systems will reduce hallucinations and drift, mitigate the risk of attacks, ensure data-handling compliance, and maximize the relevance, reliability, and accuracy of system output.
• Inform architectural choices and technology selection.
• Stay current with new Gen AI technologies and frameworks, prompt techniques, tooling, and LLMs. Prototype new patterns and inform team direction.
• Collaborate to integrate and deploy these systems into larger software stacks via APIs and multi-tenant enterprise SaaS hosted in cloud infrastructure.

What you’ll bring:

• Bachelor’s degree in computer science, engineering, or a related field. (Master’s or PhD in Machine Learning, AI, or Data Science is a plus, but not required.)
• 5+ years of production software development experience, with at least 2 years focused on machine learning or AI engineering. Experience working in a fast-paced, dynamic startup or agile development environment is highly desirable. Ability to make trade-offs and deliver results quickly with limited resources.
• Practical experience with Gen AI technologies and expertise in Gen AI concepts. Solid understanding of different types of LLMs and Gen AI architectures, such as Mixture-of-Experts (MoE), embedding models, reasoning models, foundation models, and fine-tuned LLMs, among others. Proven track record of building and shipping Gen AI features—context engineering, evaluation, RAG, and multi-agent systems. Experience with observability, evaluation, and guardrails.
• Advanced programming skills in Python and experience with AI-powered IDEs or tools such as Cursor or Windsurf. Strong programming fundamentals and software engineering best practices, with proficiency in leveraging AI code-generation tools effectively and safely.
• Experience with Azure services and Git, or similar developer tools.
• A strong intuition for how people engage with agentic AI systems, combined with the creativity, passion, and innovative thinking needed to imagine and build new software experiences that truly meet user needs.
• Strong communication skills and the ability to work effectively in a team.
• Demonstrated ability to take initiative and lead projects.

What We’re Offering

• Salary Range: $135,000 - $185,000 CAD
• Flexible paid time off, including sick and holiday
• Flexible spending accounts
• Medical, dental, & vision insurance
• Registered Retirement Savings Plan (RRSP)
• Life insurance and disability benefits
• Tuition assistance
