• Develop unit tests on NUnit / xUnit, Jest / Jasmine / Mocha / Karma to ensure stability of business logic and predictability of releases.
• Optimize high-load components using profilers and monitoring to eliminate bottlenecks, improve performance and security.
• Analyze requirements and technical risks to choose optimal solutions and form a quality architecture.
• Implement Docker and cloud services (Azure / AWS / GCP) for containerization, setting up environments and improving CI/CD processes.
• Use Agile approaches (Scrum/Kanban) to support transparent, incremental development and rapid feedback cycle.
• Implement code review and technical practices to improve code quality and standardize team approaches.
• Analyze architectural dependencies and service interactions to maintain system integrity and minimize technical risks.
• Communicate with developers, analysts, and project managersto align requirements, technical solutions, and implementations.
• Develop technical expertise on an individual growth plan to strengthen your own role and the team's engineering culture.

• Compensation commensurate with your level and technical expertise.
• Product impact — your decisions will shape system architecture, performance, and quality.
• Strong technical environment — a team of senior engineers, architects andreal processes without chaos.
• Development — individual growth plan, certifications, internal technical sessions and access to educational platforms.
• Flexibility — remote-first format, adequate schedule and healthy work-life balance.
• International interaction - cooperation with teams and stakeholders from different countries.
• Growth prospects - the opportunity to move towards architecture or technical leadership.

This is an opportunity to be not just a developer, but engineer who shapes architecture, technical quality and direction of product development.
