Senior Fullstack Developer for A&O

About this opportunity

We are now looking for Senior Fullstack Developers to join our Automation & Orchestration teams.

Team Hydra develops and operates Ericsson's internal R&D Configuration Management Database and related web services and APIs, forming a critical part of the provisioning foundation for Ericsson's R&D private cloud infrastructure. The platform is migrating from PHP to Kotlin/Spring Boot — new development is exclusively in Kotlin.

Team eStart develops Ericsson's internal self-service portal for R&D IT infrastructure — an internal marketplace where service providers publish infrastructure services (virtual machines, network configurations, storage, DNS, etc.) and service consumers order and manage instances of those services. Every R&D team that needs infrastructure goes through eStart.

What you will do

• Design frontend features using Angular (16+), Material, TypeScript, and RxJS.
• Implement backend services using Java/Spring Boot, Kotlin, Hibernate, and MySQL, including system architecture, integrations, and database design.
• Lead platform modernization efforts, migrating a PHP monolith to Kotlin microservices (strangler fig pattern) with zero-downtime operations.
• Break down requirements into user stories, refine acceptance criteria, and clarify scope with stakeholders.
• Drive adoption of AI-assisted development tools to improve workflows and code quality.
• Mentor developers through code reviews and technical leadership.
• Contribute to the technical roadmap and architectural decisions.
• Promote Agile and DevSecOps ways of working, including PI planning, retrospectives, and continuous improvement.
• Collaborate with other A&O teams, Product Owners, and Service Delivery Managers to ensure high-quality delivery.

The skills you bring

• 5+ years of professional fullstack development experience.
• Degree in Computer Science, Software Engineering, or related field — or equivalent practical experience.
• Strong frontend skills with Angular (16+)
• Backend experience with Java, Spring Boot, and Kotlin, including RESTful API design, system integration, and data modeling.
• Proficiency in Linux (RHEL, Ubuntu) and tooling such as GitLab, JIRA, and Confluence.
• Willingness to champion AI-assisted development practices (e.g., GitHub Copilot, Cursor).
• Proven ability to make architectural decisions and drive technical direction.
• Experience with Agile/DevSecOps (Scrum/Kanban), cross-functional teams, and continuous improvement.
• Strong collaboration skills; capable of working with minimal daily direction in a complex stakeholder landscape.
• Fluency in English, both oral and written.
