Backend Developer - Python

Do you have experience in VoIP?, * 5+ years of solid backend development experience

• Strong Python skills - you understand the language deeply enough to direct it, review it, and own it
• Fluent with AI-assisted development tools like Cursor, GitHub Copilot, or similar - you use them to move fast and stay sharp, not as a crutch
• Real ownership in production systems (you’ve been paged, you’ve fixed it, you’ve learned from it)
• Hands-on experience with AWS and cloud-native patterns
• A product mindset - you care about outcomes, not just implementations

Bonus points

• Experience with distributed systems, event-driven architectures, or high-volume APIs
• Familiarity with telecom or VoIP concepts (cool to have, not a dealbreaker)
