Requirements

Must have

• Experience: At least 4+ years in relevant fields.
• Technical skills:
  • Demonstrated experience working on teams and projects through the full lifecycle of full-stack development.
  • Expertise in clean architecture, git, trunk-based development, and continuous integration and deployment (CI/CD).

  • You have a growth mindset and seek mentorship to be your best selves.
