Sr. Fullstack Engineer — React / Node (вакансія неактивна)

Ground floor opportunity: Build AI + healthcare SaaS with founders who previously helped scale bootstrapped company to IPO. Hard problems + high autonomy = rapid career growth.

What We’re Building

Nesso is AI-powered software for therapists running mental health practices. It combines practice management (scheduling, billing, documentation, client communication) with AI business intelligence that helps them make better decisions about their practice and grow as business owners.

Instead of just automating paperwork, we’re building an assistant that helps therapists understand their business:

“Should I raise my rates?” “Why is revenue down?” “Is this client at risk of dropping out?”

📍 Current stage: Pre-launch, building V1

Why This Is Interesting

Proven founders who know this space:

• Fletcher Dennison (CEO) and Will Morales (CPO) were the first employees of SimplePractice — current market leader with IPO in 2021
• Spent over a decade building software that 200,000+ therapists and millions of clients use
• Self-funded = accountable to customers, not investors

Hard technical problems you’ll solve:

• AI that therapists trust with business + clinical judgment (not just transcription)
• HIPAA compliance as architecture, not afterthought
• Proactive intelligence that feels like a smart assistant
• Real-time audio → structured clinical data pipeline
• Personalization engine at scale (100K+ therapists, 1M+ clients)
• Secure, responsive architecture across platforms

Freedom to do your best work:

• Ground floor role—shape technical architecture, team culture, product direction
• Minimal process, high autonomy
• Direct communication with founders and all team members
• No investor pressure or corporate bureaucracy
