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 autonomous agents into our solutions. As we continue to advance our AI solutions, we’re looking for a Senior AI Developer who thrives at the intersection of generative AI 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.
  • Evaluate 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 designing, building and shipping production-grade AI applications that leverage frontier models.
  • Familiarity in LLM evaluation techniques: tool correctness, grounding, hallucination detection, prompt tuning, safety, etc.
  • Experience working with RAG and retrieval architectures, multi-modal inputs, external tool usage, prompt engineering, and customer-specific customization.
  • Understanding of model fine-tuning and trade-offs
  • Practical knowledge of AI observability, tracing, model evaluation and 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 coding tools (e.g., Cursor, Claude Code etc ) to define AI-first developer workflows that raise the bar for the whole team.
  • A natural coach and mentor—someone who makes the team better by sharing insights, patterns, and feedback.
  • Natural speech (voice) interaction experience is a strong plus.

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 well defined scopes.
