Senior AI Developer
RouteThis
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.
