Seeking a mid-level Frontend Engineer (React) to build complex UIs and work on AI prompt infrastructure for enterprise voice AI products.

About the Company

NWORX builds enterprise-grade voice AI products powered by a proprietary orchestration layer. Their solutions are deployed across large enterprises, educational institutions, and government-affiliated skilling centers, currently supporting over 50,000 daily active users. The company operates 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.

Role Overview

We are seeking a mid-level Frontend Engineer who thrives in high-ownership environments and excels at solving difficult technical problems at scale. In this role, you will not simply execute tasks; you will take ownership of end-to-end epics, architect solutions, and mentor junior engineers. Because our product is deeply integrated with AI, this is a hybrid role. While you will leverage your deep React expertise to build complex user interfaces, you are also expected to spend 30-40% of your time working directly with prompts and prompt infrastructure. This includes optimizing for accuracy, managing variance, reducing hallucination rates, and eliminating latency at scale through adversarial testing in production.

Key Responsibilities

• Ownership & Execution: Take full ownership of engineering epics lasting 1-2 weeks, driving them from technical design through to production deployment.
• Frontend Engineering: Build and scale complex, high-performance UIs using React, including advanced features like image streaming and real-time voice animations.
• Prompt Infrastructure & Testing: Dedicate 30-40% of your bandwidth to developing and refining prompt infrastructure. Build and run adversarial networks to test accuracy, variance, hallucination rates, and latency under brutal, high-stakes production scenarios.
• Orchestration Layer: Work directly with our proprietary orchestrator, integrating and optimizing TTS, ASR, and LLM components.
• Architecture & Quality: Go the extra mile to surface and implement the right architecture. Write strong test cases, ship clean code, and maintain a high bar for engineering quality.
• Mentorship: Actively mentor junior engineers, providing constructive code reviews and technical guidance.
• Product Engineering: Apply a product-minded approach, leveraging engineering spikes and R&D to drive new product improvements and features.

Tech Stack

• Core UI: React, React Fiber (for high-performance rendering)
• Integrations: Blender MCP, real-time image/voice streaming
• AI Stack: Custom orchestration layer, TTS (Text-to-Speech), ASR (Automatic Speech Recognition), LLMs (Large Language Models), prompt engineering tooling
• Testing & Infrastructure: Adversarial networks, production-scale testing for hallucination rates, latency, and accuracy

Experience Required: 3+ years of frontend engineering with strong expertise in React. Experience in a scaling startup or willingness to transition into a high-growth environment is preferred. Intellectual curiosity about AI infrastructure and a willingness to work hands-on with LLMs, prompt optimization, and adversarial testing are essential.
