Senior Full-Stack Developer

About the Role  

StormGeo is seeking a Senior Full-Stack Developer (Java/Angular) to join our s-Bunker (Bunker Management Platform) team and contribute to the development of high-quality software solutions that support critical operational and financial decision-making.

The s-Bunker platform helps bunker procurement professionals make better fuel-purchasing decisions by combining pricing, constraints, vessel data, and routing logic. The system is data-intensive and flow-based, with complex data processing and business logic at its core.

You will work on software that directly impacts cost optimization, route planning, and the execution of bunker procurement decisions for maritime organizations. This role goes beyond standard CRUD applications and involves taking ownership of domain logic, with a strong emphasis on correctness, robustness, and thoughtful performance considerations.

Main Responsibilities  

• Design, develop, and maintain backend and frontend applications that support complex bunker procurement and routing workflows. 
• Ensure application security by following best practices and implementing secure coding standards. 
• Implement and evolve calculation-heavy business logic, including aggregations, derived values, and scenario-based decision flows. 
• Develop flow-based applications where data moves through multiple processing stages and must remain correct and traceable. 
• Build and maintain Angular applications that present complex, data-dense information in a clear and usable way. 
• Design and maintain APIs and domain models with a strong focus on stability, correctness, and long-term maintainability. 
• Optimize application performance for large datasets and frequent recalculations. 
• Collaborate with product managers, domain experts, and engineers to translate ambiguous requirements into robust technical solutions. 
• Document system architecture and critical business logic where it adds long-term value. 

Core Requirements  

• 5+ years of experience as a Full-Stack Developer, with strong hands-on experience in Java backend and Angular frontend development. 
• Strong proficiency with Java and the Spring (Boot) ecosystem. 
• Solid experience with relational databases and data-driven application design. 
• Strong experience with TypeScript and JavaScript in production systems. 
• Experience designing and implementing REST APIs (gRPC experience is a plus). 
• Strong problem-solving skills and ability to reason about complex data flows. 
• Passion for UI/UX best practices, accessibility, and performance. 
• Good understanding of software development and best practices, including code quality, security, and performance. 
• Ability to collaborate effectively with product managers, domain experts, and engineers, and to continuously build deep understanding of a complex business domain. 
• Curiosity and willingness to learn complex domain concepts in a data-heavy, decision-driven system. 

Preferred Qualifications 

• Experience with containerized applications (Docker, Kubernetes is a plus). 
• Experience with messaging or event-driven systems (Kafka, RabbitMQ, or similar). 
• Experience with system and application architecture (e.g., Clean Architecture or similar patterns). 
• Familiarity with monitoring and observability (logs, metrics, tracing). 
• Experience with CI/CD pipelines, preferably using GitHub Actions and Terraform. 
• Experience with cloud platforms, preferably Azure. 
• Familiarity with mathematical and optimization-driven problem domains. 

Company Offers 

• Smart, creative, and innovative environment, all within a flexible hybrid work model 
• International development opportunities to support your professional growth

• Home office support (IT workstation equipment provided + a personal budget of up to 400€ for home workplace furniture) 
• Quarterly team-building events and even more fun and memorable moments together with StormGeo
