python разработчик event-driven platforms

The team develops an internally built, event-driven platform based on AWS serverless technologies.

• 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.

• 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;
• 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;
• Qualifications in data modelling and validation using JSON Schema, Pydantic, or similar frameworks;
• Excellent command of written and spoken English (B2+ level);
• Nice to have: OpenSearch development and operational experience, application profiling and memory optimization, monitoring and operating high-volume, mission-critical systems, API design and implementation, familiarity with GraphQL.

• Location-specific conditions and benefits are available depending on the selected location.
