Job description

Get AI-powered advice on this job and more exclusive features.

RouteThis is on a mission to revolutionize technical support. We build AI-powered solutions that help Internet Service Providers and Smart Home companies solve connectivity and WiFi problems—before the subscriber ever needs to call. Our customers already benefit from our SaaS solutions today and we aim to magnify that value by building agentic qualities into our solutions. As we pivot our platform to be AI-first, we’re looking for a Senior AI Developer who thrives at the intersection of applied machine intelligence and practical engineering.

What You'll Do

• Build agentic AI systems that solve real-world connectivity and support problems through planning, tool use, and multi-step reasoning.
• Lead the effort in evaluating LLM usage for safety, correctness, hallucination, contextual relevance, and performance—ensuring the right model is used for the job.
• Design robust prompts and workflows to support voice and text-based interactions across a wide variety of customer environments.
• Guide and mentor other engineers, elevating the team’s ability to build agentic systems through design reviews, pairing, and shared tooling.
• Partner with product and CX teams to deeply understand customer problems and drive intelligent solutions.
• Prototype quickly to learn what works—and scale what does.

What You Bring

• Hands‑on experience building and shipping AI-powered products.
• Familiarity in LLM evaluation techniques: tool correctness, grounding, hallucination detection, prompt tuning, safety, etc.
• Understanding of RAG, multi-modal inputs, prompt engineering, and customer-specific customization.
• Practical knowledge of LLM observability, model selection, and cost-performance tradeoffs.
• Experience working in startup or high-speed product environments, where ownership and iteration are key.
• Proven experience designing and building robust, scalable software systems.
• Experience using AI developer tools (e.g., Cursor, Copilot, Surfboard) as part of your day-to-day workflow—and a willingness to share those practices to uplift the entire team.
• A natural coach and mentor—someone who makes the team better by sharing insights, patterns, and feedback.
• Voice interface or voice UX experience is a strong plus.
• Familiarity with modern dev stacks (e.g., AWS, Python, Node.js, React) and CI/CD pipelines.

Not The Right Fit If...

• You’re focused on building AI models or frameworks from scratch.
• Your background is purely ML ops, backend pipelines, or foundational model training.
• You thrive in large, structured enterprise environments with narrow scopes.

Our Stack

We use AWS (EKS, Lambda, Dynamo, RDS), OpenAI, Snowflake, Node.js, Python, React, Android, and iOS. You don’t need to know it all—but you should be comfortable picking up new tools fast.

About RouteThis

RouteThis is a SaaS company headquartered in Kitchener-Waterloo, transforming how ISPs and smart home brands handle support. Our AI-powered platform turns reactive support into proactive resolutions—making WiFi issues faster to solve and easier to prevent.

We’re a team that values ownership, velocity, and customer obsession. We offer flexible work arrangements across Canada, competitive compensation, stock options, and a supportive environment for high-impact builders.
