    Metamindz is a UK-based IT software company providing fractional CTO services and building high-tier digital products. 

    We are looking for a Senior Software Engineer to join a very early-stage, self-funded startup that is building a mobile-first product aimed at transforming how pet-care businesses(dog walking, pet sitting, training, etc.) operate day-to-day.

     

    The product will help pet-care companies manage schedules, assign freelancers (dog walkers, sitters, trainers), handle invoices and receipts, and run their operations more efficiently - all from a single mobile app.

     

    This position is for a strong, product-minded engineer that would be excited about building the first production version of the app.

     

    Responsibilities:

     

    • Build and ship the first version of a React Native mobile application from existing designs

    • Work with Supabase or Firebase for authentication and real-time features
    • Design and work with SQL databases, ensuring clean schemas and reliable data flows
    • Handle app submissions and updates for App Store and Google Play
    • Collaborate closely with founders and product stakeholders
    • Use AI tools pragmatically to increase development speed and quality, while reviewing and owning the output
    • Write clean, maintainable, and production-ready code with a strong sense of responsibility

     

    Requirements:

     

    • 4+ years of commercial experience with React Native
    • Proven experience publishing apps to the App Store and Play Store
    • 3+ years of commercial experience with NodeJS and TypeScript
    • Hands-on experience with Supabase and/or Firebase
    • Strong understanding of SQL databases and experience using ORMs
    • Solid engineering fundamentals and ability to work independently
    • Professional proficiency in English (written and spoken)
    • Strong soft skills, clear communication, and ownership mindset
    • Comfortable using AI as a productivity multiplier
       

    Nice to Have:

     

    • Experience working with very early-stage or lean startups
    • Product-oriented mindset and ability to make pragmatic technical decisions
    • Previous experience building MVPs or v1 products from scratch

     

    What We Offer:

     

    • Short-term contract engagement (3–4 months) with clear scope and ownership
    • Fully remote work and flexible schedule
    • Direct impact on a real product from day one
    • Minimal process, no bureaucracy, no micromanagement
    • Opportunity to shape the technical foundation of a growing product
    • Competitive contract compensation, aligned with seniority and impact

     

    How to apply:

    Please send a short blurb about yourself and your favorite ice cream flavor (mine is cherry) :)
