You will be responsible for designing, coding, testing, and maintaining web software using modern technologies and best practices. \nRoles and Responsibilities:Design and develop high-quality Java applications using modern engineering practices with Java and Spring Boot.\nDesign and implement scalable microservices and secure REST APIs for customers to send data and retrieve tracking details and reports.\nDevelop event-driven services and integrations using Apache Kafka for efficient follow-up on shipments, invoices, customs documents, and other data.\nDevelop and maintain connections with external providers such as logistics companies, customs authorities, middleware solutions, and partner organisations.\nDesign and optimise PostgreSQL database schemas and queries, including performance tuning.\nDeploy and maintain applications on AWS, including containerised deployments using Docker and infrastructure managed via Terraform.\nWrite clean, efficient, well-documented code adhering to best practices and design patterns.\nParticipate in architecture discussions and technical design reviews, exercising independent judgment on design and abstraction.\nCollaborate with Product Leads, Architects, and DevOps engineers to refine technical solutions and estimate development work.\nMentor and guide junior developers on technical and professional best practices.\nParticipate in code reviews, provide constructive feedback, and troubleshoot and debug complex technical issues.\nCollaborate effectively with other developers, testers, product owners, and stakeholders.\nUse AI-assisted development tools (e.g., OpenAI Codex, Claude Code) to improve productivity while maintaining engineering quality and depth.\nKey Requirements:6+ years of professional experience as a Software Developer with Java and Spring Boot.\nExperience with Spring Data JPA / Hibernate.\nExperience with Apache Kafka and event-driven/asynchronous microservices.\nExperience with PostgreSQL (including AWS RDS PostgreSQL), SQL performance tuning, database design, and normalisation.\nWorking knowledge of AWS for application deployment, including ECS/ECR, S3, API Gateway, and CloudFront.\nExperience with Maven for build/dependency management.\nWorking knowledge of Git and JIRA in an Agile/Scrum environment. \nExperience developing and integrating with third-party APIs (both consuming and creating APIs).\nFamiliarity with common integration patterns (e.g., REST, message queues).\nStrong understanding of object-oriented programming principles and design patterns (e.g., SOLID principles, hexagonal architecture).\nExcellent software design skills with strong abstraction and modelling capability, and the ability to make independent architectural decisions.\nExperience already using modern AI development tools (e.g. OpenAI Codex, Claude Code) as part of daily workflow, with genuine depth on configuration, evaluation, and effective use (e.g., memory/context management, token usage, multi-agent setups) — not just prompt-level usage.\nPrior experience with enterprise-scale systems and AWS infrastructure is a major plus.\nHaving an AWS certification is a plus.","description_format":"text","description_chars":3250,"description_truncated":false,"requirements":{"experience_years_min":6,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["IT
