AI Agent Architect/Engineer

About VitalSpark and Bea

We're VitalSpark, and we're creating Beatrice (a nod to Dante’s muse), an AI agent who is a specialist in motivation, and a guide to your fitness journey. Think of Bea as your personal fitness buddy who's always there to give you that extra push. She learns your preferences and habits and uses the best guidance for fitness and behavioral science to create a personalized plan just for you. Our goal? To help you get healthier, happier, and help our customers achieve their long-term health goals..

Why We're Doing This

We're not just building another chatbot; we're on a mission. If Bea succeeds in moving someone from the bottom quintile in heart health to the next quintile, we will cut their mortality in half. Imagine the impact of that on millions of people. It's like finding a way to prevent a major illness. Everyone deserves to live a happier, healthier life, and we believe Bea can help make that happen for people at all fitness levels.

Who We Are 

We're a small team of committed startup veterans who have a couple of unicorns under our belts. We expect to stay a small team, and build a company with substantial revenue and major impact. Our team members have brought scores of new-to-the-world products to market. We're looking for someone who's excited to join us on this journey and help bring Bea to life. We have a unique and powerful pathway to market.  We prioritize moving faster than other startups in the space.

AI Architect/Engineer Role

You are an AI architect and engineer with a strong background in AI/ML/DS. You are familiar with the platforms required to build an AI Agent and have the passion to stay current with the explosively changing state of the art. You will play a pivotal role in shaping our AI strategy, architecture, and implementation.

As an architect you will recommend ways for Bea to:

• Partner with our behavioral science advisors to fine-tune Bea's personality to deliver optimally effective, personalized recommendations.
• Build a multi-variate testing machine to quickly iterate and learn.
• Create personalized weekly workout plans, specifying details like workout type, instructor style, and music. For example, “Monday: 30 min HIIT on the treadmill with an energetic instructor and upbeat dance music. Tuesday: 45 min Yoga recovery with calming music”.
• Spider and classify the world’s fitness videos for function, quality, and “vibe” using APIs, LLMs, and CV tools.
• Fuzzy match workout plans to our library of workout videos in dozens of dimensions.
• Make Bea an authority on strength training given 3 reference works.

You're a software engineer at heart: 

• You will build an AI agent, and you're excited about that. You need to create things, and bringing Bea to life is something you're passionate about. You will code every day.
• You work well with people and coding agents. You can talk at length about your favorite coding agent and the pros and cons of the leading LLMs.
• You have a keen awareness of when to push the boundaries of the current AI technology and when it's better to pause a feature to wait for an expected near term LLM advancement.
• You have a bias toward action and coding. You get shit done.

Essentially, we need someone who's both technically skilled and excited about helping Bea become the best personal trainer on the planet.
