What You Will Own

You will work directly with our CTO, physician founder, and engineering team to strengthen Koa’s intelligence, reliability, and safety.

Your initial responsibilities will include:

• Audit the current voice, memory, context, reasoning, and safety architecture.
• Improve longitudinal memory, temporal pattern detection, and user-state management.
• Strengthen real-time voice orchestration, interruptions, latency, and context handoffs.
• Build an evaluation system that tests each safety function separately:
  • Detect the relevant signal.
  • Ask the appropriate confirmation question.
  • Select the correct escalation.
  • Complete the handoff.
  • Monitor the later outcome.
• Create regression tests for memory retrieval, pattern recognition, intervention selection, escalation, and follow-up.
• Instrument model performance, latency, retrieval quality, failure rates, token and voice costs, and safety behavior.
• Identify when a failure is caused by prompting, architecture, data, workflow, or product design.
• Improve the existing system without proposing an unnecessary ground-up rewrite.
