• Design scalable cloud infrastructure using AWS
• Work with SQL databases and production data systems
• Build real-time voice applications using LiveKit or similar voice-agent platforms
• Develop and optimize prompt engineering strategies for conversational AI agents
• Create evaluation frameworks to measure AI agent quality, accuracy, reliability, and performance
• Improve latency, scalability, monitoring, and reliability across AI and voice infrastructure
• Integrate speech technologies including Speech-to-Text (STT), Text-to-Speech (TTS), and real-time audio pipelines
• Collaborate closely with product, engineering, and business teams to launch AI features into production
• Debug and resolve complex issues across AI models, backend infrastructure, and voice systems

Required Qualifications

• 3+ years of Backend Engineering or Infrastructure Engineering experience
• 2+ years of experience with Voice AI, Conversational AI, AI agents, or agentic workflows
• Strong production experience with Node.js
• Strong experience with AWS cloud infrastructure
• Strong knowledge of SQL and relational databases

• Experience working with high-volume conversational or voice applications
• Fintech, financial services, lending, payments, or debt collection technology experience
• Previous experience at an early-stage or high-growth technology startup

What We’re Looking For

The ideal candidate is an engineer who can work across both AI and backend infrastructure. You should be comfortable taking an AI agent from prototype to a scalable production system and solving the engineering challenges that come with large volumes of real-time conversations.

You will thrive in this role if you enjoy ownership, rapid iteration, technically challenging problems, and building AI products that are used in the real world.

Compensation & Benefits

• Base Salary: $200,000–$300,000 per year
