AI Agent Engineer

$200k - $300k

David Joseph & Company

Job Description

Job Description

Manhattan, NY · On-site · Full-time Compensation: $200,000–$300,000 + 0.25%–1% equity

About the Company

Our client is a seed-stage startup using generative AI to automate consumer debt collection, a $35B market in the US alone. Its AI agents handle the full late-stage recovery process — asset research, pre-legal outreach, litigation, credit reporting, and enforcement actions like garnishments and liens — already outperforming human collectors 2x at a fraction of the cost and running 10M+ calls per month.

Founded 2024 · ~5 people (Seed) · Industry: AI Tools

The Role

The client needs an AI Agent Engineer to build and own its voice-AI agent infrastructure end to end on LiveKit — the orchestration layer, the prompting strategy across millions of consumer interactions, and continuous performance improvement through rigorous testing and iteration. It suits a deep voice-AI engineer or a strong, analytical, business-minded infrastructure engineer equally well.

Tech stack: LiveKit, Node.js, AWS, SQL; ASR/STT/TTS, real-time audio pipelines, SIP/telephony.

Requirements
  • 2+ years in voice AI, conversational AI, prompt engineering, speech systems, or related agentic workflows
  • 3+ years in platform, infrastructure, or backend engineering
  • Strong experience with Node.js, AWS, and SQL
  • Shipped production systems in a startup or similarly fast-paced environment
  • Experience with voice-orchestration platforms or agent frameworks such as LiveKit or equivalent
  • Strong prompt-writing instincts and the ability to design resilient conversational flows for real-world edge cases
  • Strong analytical skills and comfort tying technical work directly to business outcomes and ROI
Nice to Haves
  • Voice-AI experience in production, even from a lesser-known company or background
  • Built AI infrastructure or agentic systems at a startup or AI company, with a real sense of what production-grade means at scale
  • LiveKit or other voice-orchestration-framework experience
  • Business-minded: connects technical decisions to liquidation, containment, and conversion metrics, not just engineering metrics
  • Strong prompt-engineering instincts, having designed conversational flows that handle edge cases gracefully under compliance constraints
  • Telephony-infrastructure experience such as SIP trunking
Why Join
  • Own it end to end: build the voice-AI infrastructure in-house from scratch on LiveKit — orchestration, prompting strategy, evaluation
  • Real scale, real outcomes: millions of consumer interactions a month, tied directly to liquidation, containment, and conversion metrics
  • Fast traction: ~$2M annualized run rate in a few months with a team of five, targeting $10M ARR this year
Details
  • Location — Manhattan, NY
  • Work policy — On-site
  • Compensation — $200,000–$300,000 + 0.25%–1% equity
  • Visa sponsorship — Not available
  • Employment type — Full-time
