About Veritus

Veritus Agent is building an AI-native virtual agent platform for consumer lending and collections. Backed by Y Combinator and founded by leaders from Best Egg, Affirm, PayPal, and Lending Club, we’re modernizing legacy call centers with fully compliant AI agents across voice, SMS, and email. Our platform drives higher conversions, lowers servicing costs, and improves borrower outcomes.

The Opportunity

We’re hiring an experienced Voice Agent Designer / Prompt Engineer to design, tune, and deploy production-grade voice agents across financial services use cases as we rapidly scale our customer base. This role will also be responsible for designing agents across use cases, customer profiles, and regulatory needs, while shaping our long-term strategy to stay at the forefront of AI-powered voice automation.

You’ll collaborate with the sales, compliance, and engineering teams to:

• Translate client requirements and compliance rules into robust conversational logic and prompt flows.
• Design and optimize prompt architectures and conversational flows for AI voice agents.
• Tune voice synthesis, pronunciation, and emotional tone to deliver natural, empathetic, and persuasive borrower conversations.
• Run A/B tests and human-in-the-loop QA to improve agent performance over time.
• Build scalable frameworks and tooling to ensure consistent agent quality across clients and consumer lending use cases.
• Own the roadmap for voice AI capabilities, helping define what great sounds like, and how we get there.

You’ll thrive in this role if you:

• Are an avid prompt hacker who loves crafting and refining multi-turn, emotionally intelligent dialogue and obsessing over how to make it just a little better every time.
• Have hands-on experience building complex voice agents using leading LLM and voice technologies (e.g., OpenAI Realtime, GPT-4o, ElevenLabs, Deepgram, Speechmatics).
• Keep current with the state of the art for turn-taking, latency, and interruption handling in real-time voice systems.
• Have experience optimizing voice prosody, pronunciation, and pacing for clarity and tone.
• Care deeply about building agents that are empathetic and compliant in high-stakes financial settings.
• Thrive in a fast-paced environment and enjoy collaborating as part of a high-performing, execution-focused team.

Nice to Have

• Experience in regulated or high-trust environments (finance, healthcare, or government).
• Advanced/academic knowledge of  speech-to-text / TTS pipelines, evaluation metrics, and voice quality tuning.
• Experience working with multiple different conversation design tools (Voiceflow, Rasa, Dialogflow) or real-time agent frameworks.
