• Build highly secure systems leveraging encryption, IAM, IAM roles, JWT, OAuth2, API gateways, and secrets management.
• Follow best practices such as OWASP, PCI-DSS, HIPAA, where applicable.
• Participate in and pass a full security and background verification process.

Teaching, Leadership & Collaboration:

• Mentor and guide engineering teams through code reviews, workshops, and technical training.
• Teach internal learners and participate in live sessions or demos as needed.
• Work on live client projects, deliver technical presentations, and support PoCs and architecture review.

Required Experience

• 10+ years of professional backend engineering with Python.
• Deep expertise in Python 3.6 → 3.12 (and understanding of legacy Python 2.7).
