Senior Golang Engineer
Отличная вакансия в стабильном стартапе стадии Series D с современным стеком (Go, GCP, Spanner). Предлагается хороший соцпакет, включая опционы и питание, однако гибридный график в Кракове может подойти не всем.
Сложность вакансии
Роль требует глубоких знаний Go и опыта работы с высоконагруженными системами. Дополнительную сложность добавляет необходимость работы с Google Spanner и желательный опыт в Java для понимания существующей кодовой базы.
Анализ зарплаты
Зарплата в объявлении не указана, но для Senior Go разработчика в Кракове рыночный диапазон составляет от 22 000 до 32 000 PLN (брутто) при трудовом договоре. Предложение FLYR, вероятно, находится в верхней части рынка, учитывая стадию финансирования компании и наличие опционов.
Сопроводительное письмо
I am writing to express my strong interest in the Senior Golang Engineer position at FLYR. With over 5 years of experience in backend development and a deep focus on Golang for the past 3 years, I have a proven track record of building scalable microservices and managing complex RDBMS environments. My background in designing order management features and optimizing database queries aligns perfectly with the responsibilities of your Order Management team.
I am particularly impressed by FLYR's mission to modernize the travel industry's legacy systems. Having worked with high-load services and cloud-native technologies like Kubernetes and GCP, I am confident in my ability to contribute to the reliability and performance of your systems. Furthermore, my previous experience with Java allows me to navigate and migrate legacy codebases effectively, ensuring a smooth transition to modern Go-based architectures.
I thrive in Agile environments and value the collaborative, intellectually engaging culture that FLYR fosters. I am excited about the opportunity to bring my technical expertise to your Krakow office and help drive innovation in travel technology. Thank you for considering my application.
