Job description

What we offer:

  1. The rate depends on your seniority level, skills and experience. We've already paid out over $11M to our engineers.
  2. No more hunting for clients or negotiating rates — let us handle the business side of things so you can focus on what you do best.
  3. We'll manually find the best project for you according to your skills and preferences.
  4. Choose a schedule that works best for you. It’s possible to communicate async or minimally overlap within team working hours.
  5. We respect your seniority so you can expect no micromanagement or screen trackers.
  6. Communicate directly with the clients. Most of them have technical backgrounds. Sounds good, yeah?
  7. We will support you from the time you submit the application throughout all cooperation stages.
  8. Most of our projects involve working in a fast-paced startup environment. We hope you like it as much as we do.
  9. Through our community, we will connect you with the best developers from more than 50 countries.

Requirements for the Senior React & Python Position:

  1. 4+ years of software development experience.
  2. 3+ years of commercial experience with React.js and Python.
  3. Experience with AWS, GCP, or Azure is required.
  4. Experience with Next.js, Node.js, Django, TypeScript, or AI is a strong plus.

Requirements for the Senior Node & React Position:

  1. 5+ years of software development experience.
  2. 5+ years of commercial experience with React.js and Node.js.
  3. Expertise in Next, TypeScript, and AWS, or in Next, Tailwind, and SQL, is a must.

Other requirements:

  1. 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.
  2. Clear and effective communication in English — advanced ability to discuss business tasks, justify decisions, and communicate issues. Good self-presentation is also essential for upcoming client calls.
  3. Strong self-organizational skills — ability to work full-time remotely with no supervision.
  4. Reliability — we want to trust you and expect that you won’t let us and the client down.
  5. Adaptability and Flexibility — the ability to onboard the project promptly after accepting it and start delivering results quickly.
