Job Details

We are seeking a Senior Full-Stack Developer for our client. It's a direct hire position, but there is a paid trial period of 3–6 months before signing the contract directly with the client.

You should have a strong background in .NET and modern Front-end frameworks (Vue.js or React.js). The ideal candidate will bring both breadth and depth of experience, with the flexibility to balance 50/50 Front-end and Back-end responsibilities, while maintaining a slight Back-end focus.

Location / Time Zone: LATAM, Canada, or US time zones.

We are looking for a candidate who:

  • Proactive developer with a focus on long-term, stable collaboration.
  • Strong team player, able to adapt to dynamic processes and evolving environments.
  • Problem-solving mindset with attention to detail and commitment to high-quality delivery.
  • Excellent communication skills, with the ability to clearly articulate technical concepts.
  • Human-centered approach to technology, passionate about the positive impact on people's health.

Requirements:

  • 6+ years of commercial experience in software development.
  • At least 3 years of commercial experience in front-end development.
  • 4.5+ years of experience with .NET and ASP.NET Core, ideally combined with additional back-end technologies.
  • 3+ years of experience with Vue.js or React.js.
  • Proficiency in JavaScript and TypeScript is required.
  • Architecture: Familiarity with Cloud Architecture and scalable system design.
  • Expertise with Cypress, Playwright, Mocha, NUnit, and Puppeteer.js is a huge benefit.
  • Strong technical skills: as a Senior Developer, you are expected to be able to create projects from scratch and have a deep understanding of application architecture.
  • Clear and effective communication in English – advanced ability to discuss business tasks, justify decisions, and communicate issues. Strong self-presentation skills are also essential for upcoming client calls.
  • Strong self-organizational skills – ability to work full-time remotely without supervision.
  • Reliability – we want to trust you and expect that you won't let us or the client down.
  • Adaptability and flexibility – the ability to onboard the project quickly after accepting it and start delivering results promptly.
