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:
o lambda
o api gateway
o dynamodb
o 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:
o timeouts and long-running processes
o data processing at scale
o 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
o 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
