About Murphy AIMurphy AIis revolutionizing debt collection throughconversational artificial intelligence. We're building an advanced debt recovery platform where AI agents conduct natural, empathetic conversations across multiple channels—with a special focus onvoice interactions at scale .Our AI agents don't just send emails or SMS. Theypick up the phone, understand human speech, respond intelligently, and negotiate —all while maintaining the nuance and empathy that complex financial conversations require. We're talking about real-time speech processing, emotional intelligence, and conversational flows that adapt on the fly.The challenge?Making our agents sound so natural that debtors forget they're talking to AI, while handling the complexity of financial negotiations, regulatory compliance, and emotional conversations— and making the system increasingly more intelligent with every interaction .The RoleAs ourSenior AI Engineer, you'll be at the forefront of our voice and conversational AI capabilities. You won't be building generic chatbots—you'll bearchitecting the intelligence behind thousands of daily phone calls and multi-channel conversationsthat recover millions in debt while treating people with dignity.You'll work on challenging problems where generative AI meets real-world voice interactions: designing conversational flows that handle complex negotiations, optimizing speech systems for natural dialogue, and adapting our platform to work seamlessly for different clients with varying requirements and constraints.What Makes This Role UniqueReal-world voice AI impact : Your contributions directly power live phone conversations with real peopleEnd-to-end ownership : From conversation design to deployment and optimizationComplex conversational challenges : Navigate payment negotiations, objection handling, and emotional conversationsCutting-edge tech stack : Latest LLMs, advanced TTS/STT systems, real-time processingImmediate feedback loops : See your AI agents in action and iterate rapidly️ What You'll Build️ Advanced Conversational SystemsDesign and optimizereal-time voice interaction pipelinesfor natural, low-latency conversationsBuildcontext-aware conversational flowsthat adapt tone, pace,



and strategy based on conversation stateImplement quality assurance systems that monitor and improve conversation performanceConversational IntelligenceDevelop AI agents that understand context, emotions, and intent in real-time conversationsBuildintelligent conversation routingthat knows when to escalate, when to negotiate, and when to empathizeDesign prompt strategies and agent behaviors that maximize both recovery rates and user experienceExperiment with different approaches to improve conversation outcomes continuouslyProduction AI InfrastructureOptimizelatency-critical pipelinesfor natural conversation flowBuildscalable orchestration systemshandling hundreds of concurrent interactionsDesignA/B testing frameworksfor voice and text interactionsEnsure reliability, monitoring, and observability of AI systems in productionAI Tooling & InnovationCreate internal tools for conversation analysis, quality evaluation, and performance monitoringBuild simulation and testing frameworks for conversational edge casesResearch and experiment with new AI technologies to keep Murphy ahead of the curveExplore innovative approaches to voice synthesis, speech recognition, and conversational designThe Technical PlaygroundAI & Voice Stack:LLMs : OpenAI, Anthropic and othersTTS : ElevenLabs (experience with these or similar tools is a plus)STT : Whisper, AssemblyAI (experience with these or similar tools is a plus)Real-time Communication : WebSockets, Livekit (experience with these or similar tools is a plus)AI Observability : LangFuseInfrastructure:Backend : Node.Js microservices, TypeScript, PythonMessaging : Kafka for inter-service communicationMonitoring & Observability : LangFuse, DatadogData : PostgreSQL, vector databasesWhat We're Looking ForCore Requirements4+ years of software development experiencewith a solid engineering foundationProven experience deploying Gen AI solutions in production(LLMs, RAG pipelines,
