Engagement Type: Independent Contractor · Fully Remote · Long-term
About the Role
We are seeking a Senior Full-Stack Developer to join our remote engineering team as an early technical hire. 
You will build features end-to-end — from database to user interface — help shape the architecture of our 
platform, and guide a small team of developers as we grow. This is a long-term, fully remote, independent 
contractor engagement with real ownership of your work and the stability of an ongoing role.
The position is home-based and open to applicants worldwide.
What We Offer
    • Competitive pay and a stable, long-term engagement.
    • Fully remote work.
    • Direct collaboration with the founder and genuine ownership of your work.
    • The chance to grow with an early-stage product and shape its architecture.

Duties & Responsibilities
    • Design, build, and maintain features across the full stack, from database to UI.
    • Develop secure, scalable backend APIs and services in C# / .NET, following Clean Architecture principles 
      (CQRS, dependency injection, domain-driven design).
    • Build responsive, high-quality web applications using React and TypeScript.
    • Apply engineering best practices: clean code, testing, and sustainable system design.
    • Work closely with the founder and team to plan, prioritize, and deliver features.
    • Lead and mentor a small team of developers — providing technical guidance, reviewing code, and helping 
       the team deliver high-quality software.
 Required Qualifications (Must Have)
    • 5+ years of professional full-stack development, building and deploying production applications.
    • Strong expertise in C# and the .NET ecosystem, including Clean Architecture patterns (CQRS, dependency 
       injection, DDD).
    • Strong experience with React and TypeScript, and a willingness to work across other technologies as 
       needed.
    • Skilled with AI coding tools (e.g., GitHub Copilot, Cursor, Claude) to work efficiently — while reviewing, 
       testing, and taking full responsibility for all code.
    • Strong written and spoken English for clear, proactive remote communication.
    • Able to work independently, manage priorities, and deliver reliably in a remote setup.
Preferred (Nice to Have)
     • Experience leading or mentoring a small development team.
     • Experience integrating AI features into products (LLM APIs such as OpenAI or Anthropic, smart search, 
        chat assistants, automation).
     • React Native / mobile development.
     • Cloud and Infrastructure as Code (AWS, Terraform, serverless).
     • SQL databases, payments integration (e.g., Stripe), and CI/CD.
     • Previous SaaS or startup experience with America base companies.

Qualified applicants are encouraged to send their CV with a short cover note, a link to their GitHub or portfolio,
and a link to one C# / React project they have worked on (with one or two sentences describing their role).
