Senior AWS Cloud Engineer (Serverless & Technical Ownership)

Job Description

🧭 Overview

We are looking for a Senior AWS Cloud Engineer with strong hands-on experience in Python and serverless architectures, capable of owning technical solutions end-to-end.

This is not a task-execution role.
We are looking for someone who can analyze requirements, make technical decisions, and evolve existing systems in production environments.

You will primarily work on AWS-based serverless systems already in place, focusing on:

• Enhancements and feature evolution
• New integrations
• Performance, scalability, and reliability improvements

Strong coding ability is essential — particularly in Python for backend and serverless development — combined with the ability to understand and improve system design.

Requirements

🚀 Key Responsibilities

• 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.

🧩 Required Experience

• 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

⚙️ Technical Expectations

Candidates must demonstrate:

• 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.

🧠 Nice to Have

• Experience implementing ETL processes in serverless environments
• Familiarity with tools like Terraform, CDK, or CloudFormation
• Exposure to GraphQL or gRPC
• Experience in financial or regulated environments

🧭 Working Style (Critical for this Role)

We are looking for someone who:

• Works with a high level of autonomy
• Takes ownership of problems and solutions, not just assigned tasks
• Is comfortable making technical decisions without constant supervision
• Proactively identifies opportunities to improve systems and architecture

🚨 This is NOT a role for candidates who only execute tickets or depend heavily on direction.

🌍 Communication

• 🌍 Languages
• English: Intermediate.
• Collaboration with international teams may be needed

⚠️ What This Role Is NOT

• Not a junior or mid-level execution role
• Not limited to coding tasks or ticket-based development
• Not a purely DevOps or infrastructure-focused role
