Ramat Gan, Tel Aviv, Israel Multi for All Full time ₪120,000 - ₪180,000 per year

** This position is backend-heavy and requires
Expert-level Python capabilities **

About Multi

Multi is a social impact ed-tech startup on a mission to give every child a voice. We develop cutting-edge digital AI tools to identify language development disorders early. We are expanding across Israel and looking for a passionate technical leader to take full ownership of our platform.

The Role

We are looking for a senior, high-ownership developer to take
full technical ownership
of our platform. You will be the
sole technical expert
on the team, reporting directly to the C-Level and working with high autonomy.

This is a strategic, hands-on role. We need an expert who is excited to both
maintain and build code daily
and
design the long-term technical roadmap
(architecting for scale and new features).

Crucially, this position is backend-heavy.

You are the ideal candidate if you are a proactive, senior developer ready to adopt, own, and scale a platform that makes a real-world difference.

Key Responsibilities

  • Own the Stack:
    Take full ownership of the entire development lifecycle - architecture, hands-on coding, deployment, and maintenance.
  • Build the Roadmap:
    Architect our technical strategy for scalability and our next phase of LLM/AI innovation.
  • Execute & Maintain:
    Drive all backend (Python) and frontend (React Native) development.
  • Manage Infrastructure:
    Oversee and improve our AWS cloud platform and automation.
  • Collaborate & Lead:
    Act as the key technical partner to the C-Level, researchers, and designers.

Qualifications

  • Proven experience (6+ years)
    in software development, with a strong portfolio of projects you have
    owned
    or led.
  • Expert-level Python
    and modern backend development experience.
  • Proficiency in React Native
    and the mobile ecosystem (TypeScript/JavaScript).
  • Production experience with
    LLMs
    and their practical integration.
  • Hands-on experience with
    AWS
    and cloud infrastructure.
  • Startup Mindset:
    Proactive, self-motivated, and comfortable with ambiguity. You are a natural problem-solver.
  • Experience using AI developer tools (e.g., Github Copilot, Claude) to enhance productivity.

Preferred

  • Strong knowledge of AI and voice technology applications.
  • Hands-on experience with DevOps practices (CI/CD).
  • Background in Unity3D (Android/iOS).
  • A passion for social impact and ed-tech.
