About the Role

We’re seeking a highly skilled CTO / Technical Co-Founder with deep expertise in LLM-based AI, multi-agent architectures, and human-AI interaction. You’ll own the technology vision and guide Backsie’s evolution from MVP to scalable platform as we prepare for venture financing in Q1 2026.

This is not a hands-off position — you’ll conduct a full technical audit, design the future architecture, expand the engineering team, and ensure that all AI systems are robust, low-latency, and emotionally intelligent. You’ll collaborate closely with the CEO (based in New York) and a distributed team across time zones.

Key Responsibilities

• Lead overall AI and software architecture, ensuring scalability, resilience, and data integrity

• Oversee development of LLM orchestration and guardrail agents for emotionally nuanced conversations

• Build and manage the engineering team, CI/CD pipelines, and DevOps infrastructure

• Develop RAG systems, custom datasets, and regression testing frameworks

• Collaborate with product and research to align emotional intelligence with logical structure

• Represent the technical vision to investors and partners

","main_requirements":"

• 5 + years in AI, ML, or NLP engineering (including production-level LLM systems)

• Experience with LangChain, OpenAI API, or comparable frameworks

• Solid grasp of agentic design, API-centric architecture, data pipelines, and testing automation

• Proven ability to lead technical teams in startups or fast-paced environments

• Excellent communication skills and collaborative mindset

","nice_to_have":"

• Prior startup or co-founder experience

• Familiarity with mental-health, wellbeing, or CBT/DBT frameworks

• Experience balancing safety/guardrail mechanisms and empathy in LLM products

","perks":"

Compensation & Equity

• Equity: 8 – 15 % (vesting over 48 months / 83b eligible)

• Salary (post-funding): up to $200 K USD (competitive with U.S. standards)

• Early-stage stipend or consulting arrangement may be offered until fundraising closes

Why Join Us

You’ll be shaping the foundation of a product with the potential to redefine how people reflect, reason, and heal with AI. Backsie is early enough that your contributions will shape its DNA — from technical architecture to team culture — yet mature enough to have a clear path to funding and market.

We value emotional intelligence, technical depth, and long-term commitment. If you’re ready to build something that truly matters, let’s talk
