Kitchener, Ontario, Canada Syndesus, Inc. Full time

Senior AI Developer

Company Overview

Our client is revolutionizing technical support through AI-powered solutions that help service providers and technology companies solve connectivity and network problems proactively—before customers need to contact support. They're transforming their platform to be AI-first and seeking a Senior AI Developer who excels at combining applied machine intelligence with practical engineering.

This is a hybrid role, 2-3 days onsite in Kitchener-Waterloo

What You'll Do

  • Develop agentic AI systems that address real-world connectivity and technical support challenges through strategic planning, tool utilization, and multi-step reasoning capabilities
  • Spearhead comprehensive LLM evaluation initiatives focusing on safety, accuracy, hallucination prevention, contextual relevance, and performance optimization—ensuring optimal model selection for specific use cases
  • Create robust prompt architectures and workflows supporting both voice and text-based interactions across diverse customer environments
  • Mentor and guide engineering team members, enhancing the organization's capability to build agentic systems through design reviews, collaborative programming, and shared tooling development
  • Collaborate closely with product and customer experience teams to understand user challenges and develop intelligent solutions
  • Rapidly prototype concepts to validate approaches—then scale successful implementations

What You Bring

  • Demonstrated experience building and deploying AI-powered products in production environments
  • Expertise in LLM evaluation methodologies: tool accuracy, grounding verification, hallucination detection, prompt optimization, safety protocols, etc.
  • Deep understanding of RAG architectures, multi-modal inputs, prompt engineering, and customer-specific customization strategies
  • Applied knowledge of LLM observability, model selection criteria, and cost-performance optimization
  • Background in startup or fast-paced product environments where ownership and rapid iteration are essential
  • Track record of designing and implementing robust, scalable software systems
  • Active experience with AI development tools (e.g., Cursor, Copilot, Surfboard) and commitment to sharing best practices across the team
  • Strong coaching and mentoring abilities—someone who elevates team performance through knowledge sharing and constructive feedback
  • Voice interface or conversational UX experience is highly valued
  • Proficiency with modern development stacks (e.g., cloud platforms, Python, , React) and CI/CD methodologies

Not The Right Fit If...

  • Your primary interest is building AI models or frameworks from the ground up
  • Your expertise is exclusively in ML ops, backend pipelines, or foundational model training
  • You prefer large, structured enterprise environments with narrowly defined responsibilities

Technical Stack

They leverage AWS cloud infrastructure (containers, serverless, databases), leading AI APIs, data platforms, and modern web/mobile technologies. Complete familiarity isn't required—but you should be comfortable rapidly adopting new tools and technologies.

About The Client

Our client is a VC-backed SaaS company transforming how service providers handle technical support.

They're a team that prioritizes ownership, velocity, and customer focus. They offer flexible work arrangements, competitive compensation, equity participation, and a collaborative environment for high-impact contributors.
