Senior AWS Cloud Engineer – Serverless, Technical Ownership

Role Overview

• Design and implement serverless solutions in AWS, mainly using Lambda, API Gateway, and event-driven services.
• Take ownership of technical decisions, including architecture, scalability, performance, and cost trade-offs.
• Work on existing systems, extending and improving services based on real business needs.
• Translate functional requirements into well-structured technical solutions, not just code execution.
• Build and maintain backend logic using Python, including integrations, data processing, and service orchestration.
• Implement and maintain event-driven architectures (e.g., Kafka, SNS, EventBridge).
• Ensure proper error handling, observability, and system reliability in distributed environments.
• Collaborate with backend, DevOps, and business teams to deliver robust solutions.
• Contribute to technical discussions and architectural decisions, even within pre-existing systems.
• Follow and evolve existing patterns and best practices, not reinvent unnecessarily.

Requirements

• 5+ years of experience in backend or cloud engineering roles.
• Strong hands-on experience developing backend or serverless solutions using Python (e.g., APIs, integrations, data handling, AWS SDK/Boto3).
• Proven experience working with AWS serverless services in production, particularly:
• Lambda
• API Gateway
• DynamoDB
• S3
• Experience working with event-driven systems, understanding asynchronous flows and distributed processing.
• Experience contributing to or influencing architecture decisions, especially in serverless or cloud-native systems.
• Solid understanding of microservices architecture, including when to use it vs serverless or monolithic approaches.
• Experience handling real production challenges such as:
• Timeouts and long-running processes
• Data processing at scale
• Service-to-service communication
• Ability to design solutions, not only implement tasks.
• Understanding of architecture trade-offs (cost, scalability, performance).
• Experience working with and improving existing systems, not only building from scratch.
• Practical knowledge of IAM and security best practices (e.g., least privilege applied in real scenarios).
• Experience working with CI/CD pipelines, including understanding deployment flows and making adjustments when needed.
