Lead Architect - Intelligent Voice Assistant Systems

Job Description

Job Description

Location: Flexible | Remote-Friendly
Type: Full-Time | Founding Team Opportunity

Are you passionate about building the next generation of intelligent, voice-first systems? We’re searching for a visionary technologist to shape the architecture of an advanced Virtual Personal Assistant (VPA) platform—one that lives at the intersection of human conversation, on-device performance, and AI excellence.

What You’ll Build

You’ll lead the end-to-end design of a VPA system that draws inspiration from SIRI—but reimagined with the best of today’s tools and frameworks. This includes hybrid local/cloud processing, advanced speech-to-text modeling, and seamless Apple ecosystem integration.

Tech Stack Highlights

• Platforms & Hardware: iPhone, iPad, Mac Mini M4 Pro
• Key Tools & Frameworks:

• Apple Dev Tools (Swift, Core ML)
• LangGraph Agent Orchestration
• Large Language Models (LLMs)
• Retrieval-Augmented Generation (RAG)
• ASR Technologies: OpenAI Whisper, Meta’s Wave2vec-BERT
• Hugging Face Exporters & Swift Transformers
• Accent-aware Tuning and Speech Customization
• PyTorch, Jax, Ray
• Distributed Data Processing: Beam, Spark, Dask, Ray

Responsibilities

• Define and evolve the cloud/local hybrid architecture for real-time assistant performance
• Build scalable, privacy-focused ASR and LLM pipelines for natural language understanding
• Optimize transformer models for Core ML deployment using Apple-native workflows
• Champion inclusive and multilingual voice experiences, including accent tuning strategies
• Collaborate with a tight-knit team of designers, engineers, and product visionaries

You Might Be a Fit If...

• You’ve architected complex AI systems and shipped production-grade voice interfaces
• You bring 3+ years of experience in AI/ML, with a strong focus in Automatic Speech Recognition (ASR)
• You possess working knowledge of open-source ML tools like PyTorch, Jax, and Ray
• You understand distributed data processing frameworks such as Beam, Spark, Dask, and Ray
• You’re fluent in multiple high-level programming languages—ideally including C++, Java, and Python
• You’re a bold experimenter—equally comfortable prototyping as you are writing architecture specs
• You care deeply about user experience, accessibility, and voice equity across languages and accents

Why Join Us
This isn’t just another app—it’s an opportunity to push the boundaries of what personalized, speech-driven AI can be. As a core member of our team, you'll help lay the foundation for technology that listens, learns, and adapts to people in the most human ways possible. And here's a bonus: you'll have the chance to travel to the Eastern Caribbean—on us—to test drive our product in paradise. Innovation meets island vibes
