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.

• Design and drive system architecture to ensure scalability, maintainability, and performance.

• Identify weak points in the system and design robust solutions.
• Oversee and mentor development teams, ensuring consistent technical excellence.
• Stay ahead of emerging technologies and propose innovative improvements.

• 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, Node.js, 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.
