OneSeven Tech (OST)

AI Engineer

• Configure and tune the AI voice agent on the Retell platform — conversation flows for call greeting, intent detection, caller routing, wire verification, closing date inquiries, and escalation handling
• Write and iterate on LLM prompts that control the agent's personality, decision-making, and compliance behavior
• Design multi-step conversation workflows with branching logic (e.g. caller asks about wire instructions → verify identity → look up file → confirm or escalate)
• Configure the agent's knowledge base — staff directories, office information, FAQs, and process explanations
• Work on the telephony integration layer — understanding how calls route from the PBX through to the agent and how the agent transfers calls back to specific extensions
• Own the analytics and quality layer — call scoring, sentiment analysis, intent categorization, and accuracy monitoring using Retell's analytics and custom tooling
• Collaborate closely with the backend engineer who builds the APIs the agent calls, and with the technical lead

Backend Engineer

• Build and maintain REST API endpoints called by the voice AI agent — customer file lookups, caller identity validation, and escalation triggers
• Integrate with the Qualia GraphQL API to pull real estate transaction data and build a caching layer for fast property lookups
• Connect with Microsoft Teams via the Graph API to notify staff when a caller requires a callback
• Design and maintain the PostgreSQL database — staff directory, routing configuration, call analytics, and cached data
• Set up job scheduling for Qualia data syncing and automated callback workflows
• Build the admin dashboard in Retool so the client's team can manage configuration and review call logs without engineering support
• Collaborate closely with the AI/Voice engineer and technical lead — communication with the client flows through the PM and tech lead
