Senior Java Backend Engineer - IAM & Keycloak

Why SOFICO?

At SOFICO, we’re shaping the future of mobility - and we’re doing it together. Our software, Miles, is a leading platform that enables companies worldwide to manage their leasing, fleet, and mobility operations in one integrated system. Every day, we help our customers work smarter, more efficiently, and stay ahead in a rapidly evolving industry.

Behind that impact is a close-knit, international team that values collaboration, ownership, and continuous growth. We move forward with ambition but stay grounded in a culture where people support each other and take pride in what they build.

As our platform continues to grow, secure identity and access across our products and services is becoming increasingly important. From our office in Ghent, we’re looking for a Senior Java Backend Engineer - IAM & Keycloak who combines strong backend engineering skills with hands-on experience in Identity & Access Management and application security.

You’ll help evolve the IAM foundation of the Miles platform while continuing to build and improve secure, scalable Java backend components used across our international product ecosystem.

What you’ll do...

• Design, build and maintain Java backend services and platform components supporting authentication, authorization and identity management across the Miles ecosystem.
• Integrate and customise Keycloak and implement secure identity flows using OAuth 2.0, OpenID Connect and SAML.
• Design secure integrations between microservices, applications and customer environments, with a strong focus on authentication, authorization and access control.
• Act as a senior technical contributor in IAM and security discussions, translating business and security requirements into robust backend solutions.
• Work closely with engineers, Product Owners and customers to improve our IAM architecture, engineering standards and security practices.

What you bring...

• Strong senior-level Java backend engineering experience, including enterprise applications, microservices and modern Java frameworks.
• Hands-on experience with Keycloak or a comparable IAM platform, combined with solid knowledge of OAuth 2.0, OpenID Connect and SAML.
• Strong understanding of application security, authentication, authorization, access control and secure service-to-service communication.
• Experience designing and integrating backend services in distributed or microservices-based architectures, including REST APIs and relational databases.
• Experience with, or a genuine interest in, AI-assisted software engineering. At SOFICO, we actively encourage engineers to use AI tools such as Claude Code and GitHub Copilot throughout the product and software development lifecycle - from specification and planning to implementation, testing and continuous improvement - and we’re looking for someone eager to grow that practice with us.

Earn bonus points for...

• Experience with SSO, identity federation, MFA, provisioning or user lifecycle management.
• Experience securing APIs and microservices using technologies such as JWT, OAuth scopes, roles, permissions or policy-based access control.
• Experience taking technical ownership of IAM or security architecture in a complex enterprise environment.

What’s in it for you...

• Competitive salary package;
• Meal allowance provided per working day;
• Fully covered private health insurance, so you can focus on what matters most;
• Hybrid working and flexible hours, giving you the freedom to shape your workday;
• A modern co-working space offering a comfortable working environment;
• From day one, you’ll be supported through a structured onboarding program, with guidance from a dedicated coach to help you get up to speed and grow in your role;
• And because strong teams go beyond day-to-day work, we regularly create opportunities to connect - from casual drinks to team activities and company-wide events.
