Job description

Snapshot of Your Day

Web Applications Design & Development Engineering (High Tech) work focuses on designing the look/feel/user experience in addition to programming the functionality of interactive web applications. Web Applications are defined as: Cross‑platform applications installed on remote servers and accessed through the internet, developed using standard web technologies (HTML5, JavaScript, CSS) that work across multiple devices, and used as a product by external customers.

Web Applications designers/developers create the overall visual, audio, and interactive design of the web application, manipulate design elements such as audio, video, still images, animation, text, etc., using graphic/multi‑media software (Photoshop, Illustrator, After Effects, etc.), develop architecture and program functionality using languages (ASP, Java, Perl, Python, Node.js, C++, etc.) plus scripting languages.

Specialization: Incumbents who develop websites or web applications in marketing, e‑commerce, self‑service support, account management or virtual content distribution should be matched to applicable specializations.

How You’ll Make An Impact

• This version integrates the full AWS ecosystem and code quality tools to focus on high‑throughput data streaming and serverless architecture.
• Cloud‑Native Development: Design and deploy scalable backend services using AWS ECS (Fargate/EC2) and AWS Lambda for serverless compute.
• Stream Processing: Architect real‑time data pipelines using Kinesis or Apache Kafka to handle high‑velocity data streams.
• Asynchronous Workflows: Manage distributed task queues with Celery, ensuring seamless integration between Python/Node.js services and AWS message brokers.
• Data & Storage: Optimize PostgreSQL performance and manage unstructured data storage using AWS S3.
• Security & Configuration: Implement secure credential management using AWS Secrets Manager and Parameter Store.
• Quality: Monitor application health via Sentry and enforce high coding standards through SonarQube/Sonar Cloud integration in the CI/CD pipeline.

What You Bring

• Architecture Evolution: Lead migration from legacy monoliths to high‑performance microservices and event‑driven architectures.
• Backend Mastery: 8–10 years of experience with Python (Asyncio) and Node.js.
• AWS Compute & Serverless: Hands‑on experience with ECS and Lambda functions.
• Data Streaming: Proven experience with Kafka or Kinesis.
• Asynchronous Tools: Deep knowledge of Celery for background processing and task scheduling.
• Database: Strong PostgreSQL skills (schema design, complex joins, performance tuning).
• Infrastructure & Security: Familiarity with S3, Secrets Manager, and Parameter Store.
• DevOps & Quality: Experience integrating Sonar, Sentry into CI/CD pipelines.
• Soft Skills: Ability to work in Agile (Scrum/Kanban) teams and thrive in a multicultural environment.

Benefits

• Options to work flexibly, especially after successful onboarding – remote, flexible hours or a combination.
• Distributed team collaboration.
• Opportunities to work on and lead innovative projects.
• Supportive work culture.
