Sr. Backend Developer

Senior Backend Developer (Consultant) We are seeking a Senior Backend Developer (Consultant) to accelerate the modernization of our core platform, moving from a monolithic legacy system to a highly distributed, cloud-native architecture. In this role, you will lead the integration of features across 5–6 cross-functional teams, acting as a driving technical force without needing formal authority. A core immediate focus will be contributing to our Single Sign-On (SSO) authentication platform. The ideal candidate embraces ambiguity, designs robust yet pragmatic solutions without over-engineering, and can execute efficiently leveraging AI-assisted coding tools like GitHub Copilot. Key Responsibilities · Cross-Team Collaboration: Coordinate and align with 5–6 different teams to deliver unified capabilities; unblock dependencies and influence technical outcomes across departments. · System Modernization: Design and build distributed, cloud-native backend services, focusing heavily on migrating legacy REST workflows directly into GraphQL. · Feature Ownership: Take full ownership of complex initiatives—from sparse initial requirements to production delivery—navigating ambiguity gracefully. · Product Thinking: Connect technical and architectural decisions directly to business outcomes, ensuring high performance and scalability. Required Technical Skills · Languages: Expert-level Java (17+) and Python (specifically optimized for AWS Lambda). · Frameworks & APIs: Strong experience with Java Spring Boot, robust GraphQL implementation, and legacy REST API deprecation/migration. · AWS Cloud Native Stack: Deep expertise in AWS Lambda, DynamoDB, S3, ECS/EC2, API Gateway, Secrets Manager, and Step Functions. · Event-Driven Architecture: Proven experience with Apache Kafka event streaming, alongside traditional knowledge of AWS SQS and SNS setup. · Security & Auth: Strong foundation in basic security practices, cloud-native authentication, and Single Sign-On (SSO) platforms. · CI/CD & Tools: Experience optimizing deployment pipelines (CI/CD emphasis over foundational infra), using CloudFormation, and leveraging GitHub Copilot to optimize development velocity. Preferred Qualifications · Familiarity with AWS networking fundamentals (VPCs, Subnets, Security Groups). · Exposure to Aurora DB, Data Lake fundamentals, Snowflake, or AWS Glue (ETL). RIT Solutions
