About the Role
Lemon.io is seeking a Senior Full-Stack Developer for a client. This is a direct hire position with 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.
The rate depends on your seniority level, skills, location, and experience.
Education: Bachelor’s degree in Computer Science, Software Engineering, or a related field.
We are looking for a candidate who is not just technically strong but also thrives in a mission-driven, collaborative environment:
- 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.
Benefits (Potential after direct hire)
- Stock options.
- Comprehensive health, dental, and vision plans for you and your family.
- Flexible work environment.
- Team off-sites and wellness initiatives.
- Competitive vacation policy.
