Senior Backend Developer (Java) — Crypto-Kubernetes Java

CrunchCode — міжнародна сервісна ІТ-компанія з досвідом близько 7 років у розробці вебсервісів і вебзастосунків. Ми працюємо у форматах staff augmentation (outstaff) та outsourcing і підключаємо спеціалістів до проєктів клієнтів у довгостроковій моделі співпраці.

Ми працюємо переважно з проєктами в доменах логістики (включно з last mile),e-commerce, fintech та банкінгу, а також enterprise-рішеннями.
Для нас важливо, щоб проєкт був “чистим” і зрозумілим з точки зору етики та цінності для користувачів.

Ми принципово не беремо проєкти, пов’язані з:
● gambling / гемблінгом,
● adult-контентом та порнографією,
● шахрайством або будь-якою розробкою, що спрямована на обман чи маніпуляції.

What We Offer:
● Fully remote work
● Long-term, stable project
● High level of autonomy and trust
● Minimal bureaucracy
● Direct impact on business-critical logistics systems
● Long-term engagement, not a short-term contract.

Project Overview: Senior-level backend role, ideally approaching Architect level, focused on designing and developing core backend services for ORA. The work enables secure cloud integration with SEF through KMIP and Barbican, requiring deep expertise in cryptography, Kubernetes, and open-source / open-standard solutions.

Tech Stack: Java · Kubernetes · OpenStack · KMIP · Barbican · TLS · CRDs · Distributed Systems

Requirements (Must-have):
