Java/Kotlin Developer

Job description.

Senior Java/Kotlin Developer - Hybrid role - 2 days in the office - £65-71k + market leading package.

About the Company:

Our client is building a greenfield Vendor Management System (VMS) designed to transform how contingent workforces are managed. This is a rare opportunity to join a product-led, mission-driven tech team at an early stage, with full autonomy to influence the platform's technical direction. You'll work in a modern, containerized microservices architecture built using Kotlin, Spring Boot, MongoDB, and GCP.

The Role:

We're looking for a Senior Java/Kotlin Developer with a strong backend focus and a passion for clean architecture, scalability, and developer experience. You'll be a core contributor to the backend of a greenfield system that's already gained buy-in at the highest level. You'll work with cross-functional teams to prototype, build, and launch scalable services in a distributed environment.

Key Responsibilities:


* Design and build backend services using Kotlin, Spring Boot, and MongoDB on GCP
* Collaborate with Product, Design, and Engineering teams to bring features from concept to production
* Provide technical mentorship through knowledge-sharing sessions and 1:1 support
* Contribute to the engineering culture by improving processes and raising the quality bar

Essential Criteria:


* 5+ years of experience with Java, Kotlin, or C++ in a production environment
* Hands-on experience building microservices within a service-oriented architecture
* Practical knowledge of CI/CD pipelines and containerized infrastructure (Docker/Kubernetes)
* Familiarity with cloud platforms-ideally GCP, but AWS or Azure is fine too
* Excellent communication skills and experience mentoring engineers
* Comfortable collaborating with distributed teams across time zones

Why Join:


* Build a greenfield platform from the ground up with modern tools and freedom to innovate
* Work in a supportive environment where mentorship, quality code, and engineering excellence are valued
* Remote-first setup with flexible working hours
* Competitive salary and a chance to influence a major digital transformation
