Leads efforts to re-architect and refactor legacy applications into modular, cloud-native microservices following AWS and industry best practices.
Collaborates with Product, QA, and other engineers to turn user stories into scalable, secure, and observable production features.
Owns end-to-end performance, scalability, and reliability of services — from design through deployment and monitoring.

REQUIREMENTS
5+ years professional experience developing in C#/.NET and SQL, with emphasis on backend systems and data processing.
Strong AWS expertise, particularly in serverless and managed-service architectures (Lambda, DynamoDB, S3, EventBridge).
Demonstrated experience designing and operating RESTful APIs and backend services at scale.
Solid understanding of data modeling across SQL and NoSQL systems (SQL Server, DynamoDB, S3).
Knowledge of secure development, incident response, and compliance (SOC2, GDPR, privacy standards) preferred.
Proven ability to ship, maintain, and support production services as part of a small, high-performing team.
Strong focus on end-user impact, reliability, and continuous improvement.
WHY ELEVEN
Real-world scale: Your code powers connectivity for tens of millions of devices worldwide.
Modern tech stack: Fully AWS-native with AI tooling at its core.
