Conversational AI Engineer – Game Prototype

This is a fully remote position, open to applicants in United States.

📋 Description

• Design and develop the comprehensive voice conversation pipeline connecting players and NPCs.

• Assess and incorporate technologies such as speech-to-text, large language models, text-to-speech, and speech-to-speech.

• Investigate methods for conversational memory, context, personality, and NPC behavior.

• Create prototypes for real-time conversational interactions while optimizing for latency, quality, reliability, and cost.

• Decide which elements should operate on-device versus in the cloud.

• Construct and integrate the resulting systems within Unity/C#.

• Set up an architecture capable of evolving from a prototype into a fully functional production system.

• Collaborate closely with game design and engineering teams to define technical requirements and develop natural, responsive interactions for players.

• Select the technology stack and substantiate choices with data on performance, cost, and failure rates.

• Design and create a functioning prototype of the conversational AI system within Unity.

⛳️ Requirements

• Over 5 years of professional experience in software engineering.

• At least one completed project developed in Unity using C# (such as a released game, application, or production tool); applicants must provide a link.

• A personally developed working end-to-end voice conversation loop: speech input, language model, speech output; applicants must provide a link or demo.

• Capability to select and justify technology choices based on measured response times, costs per conversation minute, and failure rates.

• Preferred: experience in game AI, NPC systems, or interactive entertainment.

• Preferred: knowledge of conversational memory and agent architectures.

• Preferred: experience with on-device speech or language models.

• Preferred: understanding of multilingual or language-focused AI systems.

• Applications must include a resume and cover letter, a link to a personally developed voice or conversational system, and brief responses regarding latency, on-device/cloud architecture, and NPC memory.

• Shortlisted candidates will be required to demonstrate their demo in a 30-minute call.

🏝️ Benefits

• Potential opportunity to continue collaborating with the team beyond the initial prototype phase.
