Senior Backend (Java) Engineer

Who we are:

Adaptiq is a technology hub specializing in building, scaling, and supporting R&D teams for high-end, fast-growing product companies in a wide range of industries.

About the Product:

We are building an AI-first platform that fuses multiple maritime data sources into a unified operational picture. The system builds a digital twin of global maritime activity, applies behavioral analytics and predictive AI models to surface smuggling, illegal fishing, container risk, and other compliance or security threats, and presents mission-grade intelligence to both commercial and government stakeholders. 

Operating at global scale, the platform processes millions of events and terabytes of geospatial data daily, relies on cloud infrastructure and microservices, and integrates with upstream research prototypes from data science teams. 

About the Role:

As a Senior Backend (Java) Engineer, you will own the end-to-end development of core data processing services within our maritime intelligence platform. 
You will collaborate closely with data scientists, analysts and software engineers to design and implement scalable microservices and streaming solutions. Leveraging AWS, Spring Boot and Kafka, you’ll tackle technical challenges around high-throughput ingestion, low-latency processing and data integrity.

Key Responsibilities:

• Develop robust, high-performance backend services using Java and Spring Boot.
• Implement real-time data streaming solutions with Apache Kafka.
• Design, build and maintain scalable data pipelines for collection, processing and transformation from diverse sources.
• Leverage AWS services for data storage, processing and analytics following security and performance best practices.
• Monitor, troubleshoot and optimize service performance to identify and eliminate bottlenecks.
• Ensure data integrity, reliability and availability through effective ETL processes and quality checks.
