Software Developer - Java Backend

Software Engineer – Java Backend / Microservices (m/f/d) Porto, Portugal | Product Engineering Why SOFICO? At SOFICO, we’re shaping the future of mobility — and we’re doing it together.

We are an international Belgian software product company developing Miles , our enterprise platform for automotive finance, leasing, fleet and mobility.

Miles supports complex business processes throughout the full lifecycle of a finance or leasing contract — from quotation and pricing to contract management, billing, assets, services and integrations.

For our growing Product Engineering team in Porto , we are looking for Java backend engineers who want to help evolve Miles and build software that is used as part of a long-term international product.

Your role As a Software Engineer in our Product organisation , you’ll work on the continued development of Miles and its backend capabilities.

This is a hands-on product development role where you’ll translate business and domain requirements into Java services, APIs and microservice-based solutions .

You won’t simply implement isolated technical tasks. You’ll work closely with other engineers, analysts and internal consumers to understand the business problem behind a feature, contribute to the technical solution and take ownership of what you build.

You’ll be working in a complex enterprise domain where maintainability, scalability, reliability and long-term product evolution matter.

Our engineering landscape includes a large Java ecosystem and an increasing focus on modern backend services, APIs, microservices, event-driven architecture and cloud-native development .

What will you do?

• Design, develop and maintain Java backend services within Miles;
• Translate complex business and domain requirements into scalable software solutions;
• Develop and evolve REST APIs used by other Miles components and integrations;
• Contribute to our microservice architecture and apply Domain-Driven Design principles where appropriate;
• Work with internal API consumers and integrations with external systems;
• Work with synchronous and asynchronous communication patterns depending on the use case;
• Take ownership of functionality from design and implementation through testing, release and production;
• Investigate and resolve issues in existing backend services;
• Write clean, maintainable and well-tested code;
• Participate in code reviews, technical discussions and engineering decisions;
• Collaborate with colleagues across Product, Analysis and Architecture;
• Help improve existing services while also contributing to new product capabilities;
• Share knowledge and contribute to our wider engineering community

• Event-driven architectures;
• Docker;

You don’t need to know every technology we use from day one. More importantly, you enjoy understanding the business domain behind the code , solving problems together with your team and taking responsibility for the quality of what you deliver. We’re open to both medior and senior engineers , depending on your experience and level of ownership.
