• Розуміє та будував microservices: межі сервісів, інтеграції, ретраї, консистентність, спостережуваність.
• Не прив’язаний до одного стеку: має досвід у кількох мовах із нашого стеку — Rust, TypeScript (NestJS), Python — і вміє впевнено перемикатися між ними.
• Має досвід з Kubernetes та DevOps: деплой, дебаг, Helm, CI/CD. У нас це частина щоденної роботи кожного розробника, не окрема роль.
• Мислить системно й архітектурно: розуміє обчислення та систему на теоретичному рівні, бачить наслідки рішень і вміє пояснювати “чому так”.
• Активно працює з Claude Code. Це обов’язкова частина нашого стеку.
 

Буде плюсом: розуміння crypto/блокчейн-домену (транзакції/мережі/базова безпека), досвід з Dart.
 

Ми пропонуємо:

• Повністю віддалений формат роботи.
• Конкурентну винагороду.
• Можливість напряму впливати на продукт та архітектуру в інноваційній AI-сфері.

• працювати з технічною документацією по API, контрактах та форматах обміну;
• брати участь в integration testing, validation і troubleshooting;
• взаємодіяти з архітектором і командами розробки для узгодженої реалізації технічних рішень.

Що для нас важливо:

• сильний досвід у software engineering у ролі Senior Backend Developer, Systems Integration Engineer чи схожій;
• досвід роботи з API design, network protocols, message contracts та data exchange formats;
• розуміння distributed systems і міжсервісної взаємодії;

• розуміння reliability, error handling, timeouts, retries, observability;
• досвід роботи з Windows та Linux;
• розуміння підходів до побудови стабільної взаємодії між компонентами системи;
• вміння працювати з технічною документацією та формалізацією контрактів;
• вміння переводити високорівневі архітектурні рішення у деталізовану технічну специфікацію.

Буде перевагою:

• досвід із self-hosted / on-prem infrastructure;
• досвід із containerized environments;
• досвід роботи з high-performance або real-time системами;
• досвід побудови fault-tolerant distributed systems;
