Software developer 2 - React - Voice AI core platform

Role Overview

NWORX builds enterprise-grade voice AI products powered by our proprietary orchestration layer. We operate at the intersection of complex frontend engineering and deep AI infrastructure, handling real-time voice animation, image streaming, and large-scale LLM/TTS/ASR integration. We are seeking a Mid-Level Frontend Engineer who thrives in high-ownership environments and excels at solving difficult technical problems at scale. This is a hybrid role where you will leverage your deep React expertise while spending 30-40% of your time working directly with prompts and prompt infrastructure.

Responsibilities

• Take full ownership of engineering epics lasting 1-2 weeks, driving them from technical design through to production deployment.
• Build and scale complex, high-performance UIs using React, including advanced features like image streaming and real-time voice animations.
• Dedicate 30-40% of your bandwidth to developing and refining prompt infrastructure, including running adversarial networks to test accuracy, variance, hallucination rates, and latency.
• Work directly with our proprietary orchestrator, integrating and optimizing TTS, ASR, and LLM components.
• Implement robust architecture, write strong test cases, and maintain a high bar for engineering quality.
• Actively mentor junior engineers through constructive code reviews and technical guidance.
• Apply a product-minded approach, leveraging engineering spikes and R&D to drive new product improvements.

Requirements

• 3+ years of frontend engineering experience with strong expertise in React.
• A proven ability to dig deep into complex problems, particularly those related to scale.
• High standards for code quality, testing, and clean architecture.
• Experience working at a scaling startup or readiness to transition into a high-growth startup environment.
• Intellectual curiosity about AI infrastructure and a willingness to work hands-on with LLMs, prompt optimization, and adversarial testing.
