About Shadow

Shadow is an AI-powered emotional companion that acts like a non-clinical psychologist in your pocket — a presence that listens, reflects, and helps people navigate emotional challenges without pressure or medication.

Born from lived experience in a conflict zone, Shadow was created for the moments where traditional support isn’t accessible or immediate — when people need understanding more than solutions. It’s a new category of mental health support : grounded in therapy principles, enhanced by AI, and built for real-world use.

Our mission is to redefine how mental health care is experienced — combining psychology, storytelling, and cutting-edge AI to offer quiet, reliable, deeply human support through technology.

Role : CTO & Co-Founder

Location : Remote

Commitment : Full-Time

Compensation : Equity-based (no salary until funding)

What You'll Do

Own and lead the entire technical strategy and execution of Shadow from zero to scale
Architect, build, and maintain our AI-powered platform (web and mobile)
Implement emotional intelligence in AI using LLMs, vector search, and memory systems
Work closely with the founder on product design, roadmap, and growth
Prototype quickly, iterate fast — bring a "launch now, fix later" mindset
Ensure user privacy, ethical AI usage, and platform security from day one
Build and eventually lead a small, focused, world-class technical team
Stay ahead of advancements in AI and mental health tech — and implement them thoughtfully

Ideal Background

Proven experience as a CTO or senior technical lead , ideally in a startup

Strong expertise in AI / ML , including :

LLM integrations (OpenAI, Anthropic, Mistral)

LangChain, custom prompt frameworks, or agent design

Vector databases (e.g. Pinecone, Weaviate)

Full-stack capabilities — from backend APIs to simple, beautiful user interfaces

Strong understanding of data privacy, security , and ethical AI practices

Comfortable building MVPs solo, deploying fast, and learning from users

Bonus if you’ve worked on :

Voice-based interactions

Emotionally adaptive UX

Mental health or wellness platforms

Products with freemium monetization models

Driven by impact, not ego. You're here to build something that lasts.

Why Join Shadow

Shadow isn’t a content platform or chatbot — it’s a new way of offering psychological support, at scale.

You'll be a true co-founder , owning the technical side of a bold, socially meaningful product.

You'll shape not just how Shadow is built — but what it becomes in the world.

If you’re passionate about AI, psychology, and meaningful technology — and you’re ready to build from the ground up — we’d love to talk.
