AI Agent Operations Specialist (FTE 60%)

About Delfa

Billions of people still suffer from everyday diseases. One key reason? Clinical trials are broken. Despite $120 billion spent each year, most trials are delayed due to bottlenecks like patient recruitment. Delfa is fixing this with autonomous AI agents. We’re building AI agents to automate clinical trials. In less than a year from launch we’ve already:

• Deployed onto 300+ trials across multiple conditions
• Reached seven figures in ARR, growing 25% MoM
• Raised an oversubscribed $3.8m seed from tier‑one AI investors

What You’ll Do

You’ll help design, review, test, and continuously improve the AI agents that interact with patients and support clinical trial sites every day. This role sits at the intersection of clinical operations, AI agent design, quality assurance, and customer delivery. You’ll use AI tools extensively, but your judgment, attention to detail, and ability to spot issues will be what makes the work reliable. You will:

• Use Delfa’s AI workflows to extract inclusion/exclusion criteria from clinical study protocols, then manually review and refine the outputs for accuracy
• Turn clinical eligibility criteria into clear, patient‑friendly screening questions suitable for voice and SMS agents
• Create and review voice agent reports that describe the agent’s screening logic, conversation flow, escalation rules, and operational setup
• Support script creation for IRB/ethics submissions, adapting agent scripts to customer templates while preserving clinical and operational accuracy
• Assist with AI agent management, including manual patches and configuration updates where API‑based changes are not yet suitable
• Sample real calls and patient interactions to identify issues, test fixes, and add recurring items to the monitoring list to inform future automated QA
• Support pre‑release testing of AI agents before they go live with patients
• Once comfortable, design new AI agents end‑to‑end, which will then be reviewed and tested by senior team members
• Work closely with product, engineering, and customer‑facing teams to ensure agents are safe, accurate, and operationally useful for clinical research sites

You’ll Be A Great Fit If…

• You have attention to detail. You’re comfortable reviewing dense clinical or operational documents and can spot when something is missing, unclear, or inconsistent.
• You are comfortable using AI tools. You don’t need to be an engineer, but you should be excited to use prompts, structured workflows, and internal tools to produce high‑quality work faster.
• You are clinically or scientifically literate. Experience with clinical trials, healthcare, life sciences, medicine, nursing, pharmacy, psychology, or biomedical sciences would be valuable.
• You care about quality. Our agents interact with real patients and support real clinical trials, so accuracy matters. You take pride in work that is careful, clear, and reliable.
• You can move quickly without being careless. Delfa is growing fast, and we need people who can learn quickly, make good judgments, and improve the process as they go.
• You have an ownership mindset. When you notice something is broken, unclear, or inefficient, you don’t just flag it, you help fix it.
• You communicate clearly. You can explain complex clinical or operational logic in simple, structured language that customers, internal teams, and AI agents can all understand.

Nice to have:

• Experience in clinical trials, patient recruitment, site operations, IRB/ethics submissions, or healthcare operations
• Familiarity with inclusion/exclusion criteria, study protocols, or prescreening workflows
• Experience in QA, call review, operations, or process improvement
• Comfort working with structured documents, spreadsheets, or configuration tools
