Senior Java Software Engineer - Modernization Program

About the role

A large-scale modernization program is looking for a hands-on Senior Java Software Engineer to evolve a high-volume legacy platform. You will build Java and Spring Boot middleware, modernize data access with PostgreSQL and contribute to cloud-native services on Azure, while exploring AI capabilities such as Retrieval-Augmented Generation (RAG) and LLM integrations. Prior C/C++ experience is valuable but not required.

Key responsibilities

• Design and build scalable Java and Spring Boot services that modernize interactions between existing applications and PostgreSQL.
• Implement production-ready data access and integration components using Spring JDBC, Hibernate, REST APIs and modern backend patterns.
• Apply AI and RAG to engineering and platform use cases, including retrieval pipelines, embeddings, vector search, LLM integrations and AI-assisted access to technical knowledge.
• Explore generative AI and agentic solutions, balancing accuracy, security, observability, performance and business value.
• Debug and analyze complex system interactions, message flows and integration points across modern and legacy components.
• Improve performance and resilience through PostgreSQL optimization, caching with Redis or Caffeine, observability, automated testing and incremental migration.
• Collaborate with engineers and client stakeholders on design decisions, trade-offs, risks and recommendations.

Required profile

• Strong hands-on experience building production applications with Java and Spring Boot.
• Experience with Spring JDBC and/or Hibernate, including transactions and connection-pool management.
• Strong knowledge of PostgreSQL or comparable relational databases, including query optimization and indexing.
• Hands-on experience with Azure and cloud-native engineering; practical understanding of Generative AI, LLMs or RAG.
• Ability to explain technical decisions clearly to engineers and client stakeholders.

Required skills

• Building and integrating REST APIs and distributed backend services.
• CI/CD, automated testing, observability, debugging and Infrastructure as Code.
• Experience with Redis, Caffeine, Kafka or similar high-volume distributed systems is a plus.
• Working knowledge of C or C++ is a plus.

What we offer

• Inclusive workplace with ongoing learning and development opportunities.
• Competitive compensation and benefits, including comprehensive health coverage for you and your family.
• Paid leave and holidays, wellness program and employee assistance.
