Description

Backend Service Layer Engineer

We are looking for a highly experienced and motivated Backend Service Layer Engineer to design, build, and maintain robust, scalable, and secure microservices architectures and APIs. This role will leverage AWS cloud services, implement efficient caching strategies, and deliver solutions that meet high availability and performance standards. As a Software engineer, you will be responsible for building cloud-native microservices, ensuring smooth integration across systems, and collaborating with cross-functional teams to drive the architecture and technical decisions for enterprise-grade applications.

________________________________________

Key Responsibilities

• Design and develop microservices using Node.js and Python, leveraging AWS cloud services for scalability and high availability.

• Build, deploy, and maintain cloud-native microservices architectures utilizing AWS technologies like Lambda, API Gateway, AppSync, SQS, SNS, DynamoDB, PostgreSQL, Amazon Simple Email Service (SES), and ElastiCache.

• Implement Redis or Amazon ElastiCache for caching to enhance performance and reduce latency across microservices.

• Design and implement RESTful and GraphQL APIs for efficient inter-service communication.

• Develop serverless and containerized microservices using AWS services and tools like AWS ECS, Docker, and Kubernetes.

• Write clean, maintainable Python code for backend systems and microservices logic, using frameworks such as Flask, FastAPI, or Django.

• Implement security best practices for microservices, including IAM roles, API authentication, and encryption.

• Collaborate with DevOps teams to define and implement CI/CD pipelines for seamless deployment of microservices using GitLab CI/CD and monitor service health with CloudWatch or Splunk.

• Design and optimize microservice communication patterns, including event-driven models, message queues (SQS, SNS), and data stores (DynamoDB, PostgreSQL).

• Troubleshoot and optimize microservice performance, ensuring high availability and fault tolerance.

• Mentor junior engineers and contribute to code reviews and technical decision-making.

• Collaborate with cross-functional teams (front-end, DevOps, QA) to ensure smooth service integrations.

• Maintain technical documentation and ensure adherence to Agile methodologies.

Additional Skills & Qualifications

NAEP Overview:

NAEP stands for National Assessment of Educational Progress. The National Assessment of Educational Progress (NAEP) is the largest national assessment provider for American students. NAEP academic assessments are the “Nation’s Report Card” and are leveraged by local, state and federal agencies to measure and act upon a clear picture of student academic progress year over year.

ETS (Educational Testing Service) has developed applications, services, interactive ‘item’ (test question) development and reporting on behalf of the NCES since 1983 and is looking to upgrade the current NAEP website, NAEP Data Explorers and reporting to provide improved features, as well as, a tablet optimized user experience.

ETS has been engaged for another multi-year project to build a brand new platform and migrate the entire NAEP work in to the cloud. This innovative development will be known as “next generation” for NAEP. It will basically be building a new cloud domain for test delivery. This won’t necessarily be like for like migration and may include new features, functionality and enhancements to what is existing. There may be additional NAEP resources needed so ETS will be looking to hire several candidates for this huge initiative. The NAEP contract requires resources to deal with external vendors in an “agency” type of environment, complete on-going NAEP content development, and keep up with/not be bothered by the constant change requests for the project.
