Java Architect

Quick application:We are seeking an experienced Solutions Architect to lead the design and implementation of robust, scalable microservices using Java/JVM frameworks (Java 17+, Spring Boot/MicroProfile, or equivalent). You will architect a modern cloud-native application suite, guiding the migration from legacy RPG-based systems to a future-proof, AWS-powered microservices ecosystem.Essential functions- Core Platform: Java/JVM-based frameworks (Java 17+, Spring Boot/MicroProfile, or similar) for building microservices. Will be a Java application suite, replacing RPG code- Design end-to-end architectures for Java-based microservices, leveraging frameworks like Spring Boot or MicroProfile.- Lead the migration strategy from RPG (Report Program Generator) codebases to modern Java applications.- Architect and implement cloud-native solutions on AWS, ensuring best practices in security, scalability, and cost-efficiency.- Oversee the setup of AWS compute (EC2, Lambda, EKS/ECS), storage (S3, RDS, DynamoDB), and infrastructure automation (Terraform, CloudFormation).- Define API contracts, service orchestration, and data integration patterns.- Guide development teams on adopting microservices, DevOps pipelines, and infrastructure-as-code.- Collaborate with stakeholders including developers, product owners, and business analysts—to gather requirements and deliver effective solutions.- Optimize system performance, reliability, monitoring, and disaster recovery protocols within AWS.- Stay updated on emerging technologies and recommend improvements to maintain modern, maintainable architectures.- Comfortable learning new technologies on the job- Claude 3.7 or 4 Sonnet LLM- AST (abstract syntax tree)Qualifications- Proficiency in English (B2+) is essential with great communication skills.- Java Expertise : Deep hands-on experience with Java/J2EE, Spring Boot (or equivalent) and designing microservices-based applications. Strong understanding of object-oriented design and enterprise patterns.- Cloud Architecture : Proven track record designing and implementing AWS solutions. Comfortable with AWS compute (EC2, Lambda, EKS/ECS), storage (RDS, S3, DynamoDB), and security best practices. Experience with infrastructure-as-code (Terraform, CloudFormation) is expected.- AWS Bedrock- AI/ML Awareness : Interest or experience in generative AI (LLMs) and RAG for code/documentation tasks. Knowledge of how static analysis and LLMs can automate migrations will help.- Legacy Modernization Experience :- Understanding of SDLC and agile in particular- Hands-on experience with developer daily basis tools such as IDE’s, compilers, debuggers, profilers, version control systems, bug tracking systems, build systems, code coverage and automated testing tools- Ability to proactively identify and solve engineering problems in a simple manner.- Good interpersonal communication skills, both verbal and written.Would be a plus- Prior involvement in a legacy-to-modern migration (e.g. mainframe or IBM i/AS400 modernization) is highly desirable. Familiarity with RPG (Report Program Generator) or other IBM i technologies (DB2, CL) is a plus. You should be able to reverse-engineer and interpret legacy code and data models- Visual representations of code flows to illustrate process sequences, data handling, and functional relationships within the modules. Mermaid.JS- Domain Knowledge : Experience in automotive, transportation or enterprise services (dealership systems, supply chain) is a bonus.- Additional Languages : Familiarity with Python (for scripting LLM tools, data processing).- Soft Skills : Prior experience in POC/proof-of-concept projects or architecture prototyping.- Experience in API development and knowledge of the main principles and best practices
