Strong experience across the full software development lifecycle, including architecture, development, testing, CI/CD, containerization, and cloud deployment.

Responsibilities

Design and implement robust Java based microservices that process and serve complex geospatial data while maintaining high performance and reliability for enterprise applications.
Develop and optimize Spring Boot services that integrate geospatial libraries and data sources to deliver efficient spatial queries and analytical features for business users.
Configure and manage AWS EC2 environments to host and scale Java microservices that support geospatial workloads with strong focus on availability and cost efficiency.
Collaborate with product owners and geospatial analysts to translate domain requirements into technical designs and implementation plans that align with organizational objectives.
Review and refactor existing Java and Spring Boot codebases to enhance modularity, maintainability, and adherence to best practices across microservices architecture.
Implement secure interfaces and APIs that enable reliable data exchange between geospatial services, external systems, and client applications following industry security standards.
Monitor application performance and resource utilization on AWS EC2 instances and propose improvements that enhance throughput, stability, and user experience.
Coordinate with quality engineering teams to define test strategies for microservices including unit, integration, and performance testing for geospatial processing flows.
Prepare detailed technical documentation that covers architecture decisions, deployment configurations, and operational procedures for Java and Spring Boot services.
Mentor team members on advanced Java concepts, microservices patterns, and effective use of Spring Boot features to maintain consistent engineering quality.
Engage with stakeholders to plan delivery milestones, estimate effort, and ensure that geospatial solutions are delivered on schedule and within defined quality expectations.
Ensure compliance with organizational governance standards, data protection guidelines, and regulatory requirements in all geospatial solution components.
Drive continuous improvement initiatives by identifying opportunities to adopt emerging tools, frameworks, and patterns that enhance geospatial capability within the organization.

Qualifications

Demonstrate strong proficiency in core and advanced Java concepts including multithreading, collections, and performance optimization applied to geospatial processing scenarios.
Exhibit hands‑on expertise with Spring Boot for building microservices including dependency injection, RESTful services, configuration management, and observability.
Show practical experience designing and deploying microservices architectures that handle high volume and low latency geospatial data transactions.
Apply working knowledge of AWS EC2 for provisioning, configuring, and managing compute resources that host Java based microservices in production environments.
Utilize experience with geospatial concepts such as coordinate reference systems, vector and raster data, and spatial indexing to design effective solutions.
Display familiarity with relational and NoSQL data stores commonly used for geospatial applications and design schemas that support efficient spatial queries.
Use strong understanding of CI and CD practices to automate build, test, and deployment pipelines for Java and Spring Boot microservices.
Demonstrate ability to analyze complex problems in geospatial workflows and propose practical and scalable technical solutions.
Communicate effectively with cross functional teams and stakeholders to ensure clear understanding of geospatial solution capabilities and constraints.
Maintain focus on quality and maintainability by adhering to coding standards, conducting reviews, and encouraging continuous learning within the team.
Leverage prior experience of eight to twelve years in Java development to guide architectural decisions and ensure resilient microservices solutions.
Prefer exposure to additional cloud native services such as container orchestration and monitoring tools that complement AWS EC2 deployments.
Value experience working in office based agile environments where close collaboration and quick feedback cycles are essential for project success.

Certifications Required: Preferred certifications include AWS Certified Developer Associate or AWS Certified Solutions Architect Associate and Java focused credentials such as Oracle Certified Professional Java Programmer.
