  • Act as a mentor to other front-end engineers and contribute to core architectural decisions.
  • Proactively propose new ideas, challenge assumptions, and influence the product roadmap with a strong product mindset.
  • Comfortably navigate backend systems (Node/TypeScript, Python AI pipelines) and infrastructure (Google Cloud, Airflow) to ensure smooth operations and unblock development.

Qualifications

  • 5+ years of experience building and launching B2C mobile products, ideally within an early-stage startup environment.

Required Skills

  • Deep proficiency in React Native and TypeScript, with comfort in incorporating native code when necessary.
  • Proven track record of taking initiative, making sound judgments, and adapting quickly in a dynamic environment.
  • Experience leading or mentoring junior developers through code reviews and design sessions.
  • Familiarity with our stack: React Native, TypeScript, Python (AI), Node, Postgres, GCP, Terraform.

Preferred Skills

  • Direct collaboration and mentorship from the founder and senior technical advisors.
  • Significant autonomy and the chance to shape the product from an early stage.

  • Opportunity for immersion sprints in Silicon Valley.
  • A flexible hybrid work structure and a culture that prioritises impact over bureaucracy.
