** We're working with a leading global technology solutions powerhouse on this exciting opportunity. We are looking for an elite Python Developer to drive high-impact application development within a sophisticated AWS environment.

**What You'll Need

**

• 5+ years of professional, hands-on Python development experience (pure software engineering, not just scripting).
• Expert-level knowledge of the AWS ecosystem, specifically around networking, security best practices, and IAM.
• Extensive experience building and hosting applications within AWS, including recent hands-on Serverless/Lambda development.
• Proficiency in Boto3 and Flask API development for building enterprise-grade interfaces. Browse our curated collection of remote jobs across all categories and industries, featuring positions from top companies worldwide.

• 100% remote working flexibility for a better work-life balance.
• The chance to work on high-profile, mission-critical AWS application projects.
• Direct engagement with a global industry leader in technology services.
