Job Description
Senior Technical Lead - Java, Spring, Hibernate, MongoDB
Montreal, Quebec

Job Summary

We are seeking a Mid-Level Java Developer to join our core engineering team. This role is designed for a developer who excels in high-throughput, distributed environments and is passionate about building scalable, real-time data pipelines.

You will be a key contributor to our backend services, primarily utilizing Spring Boot, Apache Kafka, and MongoDB. As we move toward a fully real-time architecture, you will help us bridge our relational and non-relational worlds using modern Change Data Capture (CDC) patterns. We value a candidate who is strong in SQL and excited to work with or learn specialized tools like Debezium.

Key Responsibilities

  • Microservices Development: Design and develop robust, high-performance microservices using Java (11/17+) and the Spring Boot framework.
  • Real-time Data Streaming: Implement and manage Kafka producers, consumers, and stream processing logic to handle high-volume event data.
  • NoSQL Data Architecting: Build and optimize document-based schemas in MongoDB, focusing on aggregation, indexing, and performance tuning.
  • CDC & Data Integration: Work with (or learn to implement) Debezium connectors to capture row-level changes from relational databases and stream them into Kafka.
  • Cloud-Native Deployment: Support the containerization of services using Docker and assist in managing deployments within a Kubernetes environment.

Hybrid Data Management: Leverage your SQL expertise to interface with legacy relational databases (SQL Server/Oracle/PostgreSQL) and ensure data consistency across systems

Skill Requirements

  • Java Mastery: 5–6 years of professional backend development experience with Java and Spring Boot.
  • Messaging & Streaming: Hands-on experience with Apache Kafka (topic design, consumer groups, and partitions).
  • NoSQL Proficiency: Solid experience with MongoDB (schema design and aggregation framework).
  • SQL Experience: Strong proficiency in SQL and experience working with relational databases (SQL Server, Oracle, or similar).

Other Requirements

  • CDC Tools: Experience with Debezium or similar Change Data Capture frameworks is a huge plus. Candidates without experience must be willing to self-learn this technology.
  • Kubernetes: Experience deploying and scaling applications in Kubernetes clusters (understanding Pods, Services, and ConfigMaps).
  • Containerization: Proficiency with Docker and container orchestration.
