Amazon Cloud Native Python Developer

EPAM·Lithuania, Latvia·Удалённо, Офис·5д. назад

We are seeking an experienced Amazon Cloud Native Python Developer to join our team working on an internally developed, event-driven platform built on AWS serverless technologies.

This role is ideal for an engineer experienced in event-driven systems built on AWS integration tools, or an Operations expert skilled in AWS, DynamoDB, and OpenSearch. The team owns the architecture, infrastructure, and end-to-end testing strategy, so engineers are expected to work effectively within an established codebase and set of engineering conventions rather than focusing solely on greenfield development.

Responsibilities

Work independently with minimal supervision
Make sound technical decisions and justify trade-offs
Navigate and contribute to complex distributed systems
Influence architectural direction, not just implement requirements
Design, build, and maintain event-driven services running on AWS serverless infrastructure
Contribute to architectural decisions and document design choices
Develop and maintain infrastructure using Infrastructure as Code
Ensure reliability, scalability, and operational excellence across services
Write and maintain automated end-to-end tests
Collaborate with other engineers to evolve platform capabilities and engineering standards

Requirements

6+ years of relevant professional experience with Python as a primary development language
Solid understanding of AWS architecture, including VPCs, networking fundamentals, and multi-account environments
Knowledge of AWS security, operational best practices, and how AWS services integrate within larger systems
Hands-on experience with AWS Lambda, event-driven application design, and production operation of serverless workloads
Expertise in messaging and integration patterns, with experience designing and operating systems using EventBridge, SQS, and SNS
Understanding of asynchronous communication patterns and distributed system design principles
Proficiency in Infrastructure as Code using AWS CDK, ideally in TypeScript (application code is primarily Python; infrastructure is defined in TypeScript)
Deep operational and architectural expertise in DynamoDB, including single-table design, access-pattern-driven modelling, and GSIs/LSIs
Competency in DynamoDB capacity planning and capacity modes, Streams, and TTL
Skills in DynamoDB Point-in-Time Recovery (PITR), operational monitoring, and troubleshooting beyond basic CRUD operations
Strong understanding of distributed data consistency, including ACID vs. BASE trade-offs, eventual consistency, and implications of consistency models in DynamoDB and event-driven architectures
Background in designing and operating event-driven microservice architectures, covering service boundaries, event contracts, failure handling, and scalability/resiliency
Capability to evaluate multiple design approaches, make informed architectural decisions, and drive technical direction independently while clearly communicating and documenting trade-offs
Experience with automated testing strategies, including end-to-end testing, with familiarity with BDD frameworks such as Behave being highly desirable
Qualifications in data modelling and validation using JSON Schema, Pydantic, or similar frameworks
Excellent command of written and spoken English (B2+ level)
