- agent architectures, and
- 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.

• Build and manage the engineering team, CI/CD pipelines, and Dev
  Ops 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
  - level LLM systems)
• Experience with Lang
  Chain, Open
  AI 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
- paced environments

- Excellent communication skills and collaborative mindset

Nice to have

• Prior startup or
  - founder experience
• Familiarity with
  - health, wellbeing, or CBT/DBT frameworks
• Experience balancing safety/guardrail mechanisms and empathy in LLM products

Benefits & 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

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
