• Provide deep technical expertise in backend development, code reviews, and architectural discussions, ensuring best practices are followed. • Design, develop, test, and deploy backend software solutions using Node.js and Java, adhering to high-quality standards. • Architect and optimize relational database schemas, write efficient queries, and ensure data integrity and performance. • Develop and maintain components for real-time communication, including SIP signaling and RTP streaming. • Explore and implement solutions for audio/video media processing and integration within the contact center environment. • Contribute to the development of contact center-specific features and integrations, understanding the nuances of the domain. • Identify and address performance bottlenecks, ensuring the platform can scale to meet growing demands. • Diagnose and resolve complex production issues, providing timely and effective solutions. • Work closely with product managers, architects, QA engineers, and other stakeholders to deliver high-quality software.

• Develop and maintain your squad’s microservices, delivering complete features — from design to implementation, including deployment and production monitoring. • Work with serverless and event-driven architecture: AWS Lambda, SQS, SNS, DynamoDB Streams, with attention to idempotence, retries and DLQs. • Model data in DynamoDB and build REST APIs (and expose/consume GraphQL via Apollo Federation) with high quality. • Actively participate in code reviews, design documents and RFCs, providing and receiving technical feedback. • Support and help resolve incidents within your squad’s domain. • Collaborate with product, data and security teams in an agile environment. • Take ownership of medium-sized tasks with autonomy and communicate clearly in writing.

• As a mid-level backend developer, you will be responsible for developing new features and evolving the current product in projects related to our e-commerce. • Your role includes working with the team and the Tech Lead to design robust architectures and implement development best practices. • You will also participate in defining technical standards, supporting less experienced developers and ensuring the quality of code in production. • You may contribute to our open-source repositories, attend technology events and write technical articles about your challenges. • Work on the development and maintenance of backend systems (e.g., Python with Django, Node.js with NestJS, and Golang). • Collaborate with the team to define and implement scalable, secure software architectures. • Participate in strategic decisions for evolving systems toward microservices. • Review code and support other developers. • Automate and optimize CI/CD processes and deployments in cloud environments. • Implement automated tests and monitoring processes. • Collaborate with other teams (frontend, DevOps, QA) to ensure system integration and quality.

• Develop and maintain scalable, resilient RESTful APIs in Ruby on Rails • Participate in the full development lifecycle: architecture, implementation, automated testing, deployment and production monitoring • Work on the evolution of the core (monolith) as well as on microservices initiatives and integrations with partners (e.g., ERPs, payment gateways, external platforms) • Ensure technical quality through code reviews, engineering best practices (Clean Code, SOLID) and team standards • Monitor and optimize performance: APM, resource tuning, query analysis and optimization • Work in multidisciplinary squads using an agile model (Scrum/Kanban), with close collaboration between engineering and product • Move between contexts (when necessary) with teams and workflows in TypeScript and mobile, maintaining a systemic view
