Who We're Looking For

We're looking for a Senior Software Architect / Platform Owner — a true all-around badass engineer who can understand complex systems end-to-end, take complete ownership of the platform, and execute on high-level initiatives.This person will serve as the right hand to leadership — someone who can see the big picture, make technical decisions with confidence, and roll up their sleeves to build, scale, and refine systems when needed.This is a senior-level hands-on role for someone who thrives on ownership, autonomy, and making things happen.
Primary Responsibilities

8+ years of professional software development experience.Proven background as a Senior Engineer, Tech Lead, or Architect on complex systems.Deep understanding of fullstack architecture (frontend, backend, cloud, and DevOps fundamentals).Proficiency in modern JavaScript/TypeScript, React, , and AWS or Azure.Strong problem-solving, communication, and decision-making skills.Ability to lead by example — hands-on, proactive, and execution-focused.Excellent English communication skills (written and verbal).
Nice to Have:
  • Experience in system modernization, cloud architecture, or platform migrations.
  • Familiarity with Python, Terraform, or GCP.
  • Previous experience in leadership or advisory roles within fast-scaling companies.Where We're Looking For It:
    Brazil
    Open to 100% Fully Remote
    Other Information

The work hours will be approximately 9:00 am to 5:00 pm EST, depending on workload, with the occasional late night when a tight deadline calls for it. We work for security-conscious clients, thus background checks will be required.

Position available immediately.
