Senior Software Engineer, AI Voice Agent
As a Senior Software Engineer on the AI Voice Agent team, you will work on real-time systems involving live audio streaming and latency optimization integrated with speech providers. You will build and improve conversation intelligence systems that manage LLM layers, including prompt construction, context management, function calling, and dialogue management to create natural, actionable phone conversations. You will develop the action framework allowing configurable API calls with branching logic and runtime execution, supporting tasks like data lookup and ticket creation during calls. You'll manage knowledge ingestion, storage, and retrieval to enhance agent memory and learning over time. You will collaborate with designers to enable customers to create, configure, test, and deploy voice agents through intuitive product experiences. Additionally, you will help develop evaluation frameworks, analytics, call quality metrics, and monitoring instrumentation, and participate in on-call rotation duties.

Senior Consultant (McKinsey / BCG / Bain) - Freelance AI Project
Build realistic consulting project environments by creating detailed project scenarios including industry context, financials, constraints, and incomplete information. Design structured consulting tasks for AI Agents by breaking projects into tasks that reflect real consulting work such as market sizing, due diligence, cost reduction, growth strategy, or operational diagnosis. Define evaluation criteria and quality standards by developing a grading approach, evaluation criteria, and golden solutions for each task that will be used to train and calibrate an LLM-based grading system to evaluate AI outputs at scale. This role is a remote, individual-contributor, project-based position focused on analytical design and evaluation.
