• Application development for distributed systems • Profiling and optimizing performance • Scaling for large amounts of load, data, and users • Testing of backend application • On-call technical support on a rotating schedule

• Design, build, and maintain backend services using C# and .NET Core, focusing on shared and reusable platform components. • Model, query, and optimize relational databases using SQL Server, PostgreSQL, or similar technologies. • Develop and maintain Angular-based frontend components, including form-heavy and data-driven administrative screens. • Apply RxJS and reactive programming patterns to handle async flows and state management. • Work with messaging systems (RabbitMQ) to support asynchronous, event-driven communication. • Use logging, search, and observability tools (Elastic stack or similar) to improve system visibility and reliability. • Leverage AI-powered development tools (such as GitHub Copilot, Cursor, or similar) to improve productivity and code quality. • Participate in architectural discussions around microservices, scalability, and system design. • Support and guide teams during legacy-to-modern architecture migrations, providing hands-on technical input.

• Develop and optimize core backend functionality of the AppFollow product • Build and maintain systems for user interaction with product data • Design, develop, and support a source-agnostic data storage layer that enables efficient, fast, and reliable data delivery to end users • Develop and support systems for generating insights from various types of customer and product data (including ratings, reviews, and other data sources), with a focus on flexible and custom reporting • Support internal and public APIs for core data entities, following API-first principles • Design, build, maintain and document an efficient, testable, reliable, secure and scalable codebase. • Contribute with other developers to design and improve the entire system architecture. • Interaction with legacy services • Collaborating with the Platform team to deploy the application to various environments and ensure smooth operation, adopt accepted standards, practices and processes to the maintainable systems.

• You’ll develop new features within a modular architecture while migrating existing legacy code into it. • You’ll architect solutions that ensure scalability, security, and maintainability. • You will collaborate with product management, design, and engineering toward viable product development changes from discovery to delivery. • You will mentor other developers regularly with pair programming, code reviews, and alike.
