    $70,000 - $130,000 (CAD) per year *
    Description
    We are seeking a highly skilled Senior Software Engineer to join our backend engineering team. This role focuses on designing and delivering high-throughput, low-latency, and resilient services that power mission-critical data processing pipelines.

    You will work closely with architecture, DevOps, and product teams to build scalable systems that support millions of transactions daily.

    ________________________________________
    Key Responsibilities


    • Design, implement, and optimize backend services handling high-volume data flows with strict performance and reliability requirements.
    • Develop Java-based components using modern frameworks (Spring/Spring Boot or equivalent).
    • Build and maintain asynchronous and event-driven workflows using messaging systems such as MQ/Kafka/RabbitMQ.
    • Implement performance tuning, profiling, and observability to support sub-second latency and 99.99% availability goals.
    • Drive solutioning and system designs for new features, integrations, and platform enhancements across distributed systems.
    • Ensure service robustness through automated testing (unit, integration, load tests) and CI/CD workflows.
    • Apply secure-by-design principles, including threat modeling, safe data handling, API hardening, and least-privilege access.
    • Implement and support authentication and authorization patterns (e.g., OAuth2, mTLS, JWT, service-to-service auth).
    • Participate in architecture reviews, offering technical leadership and mentorship to junior engineers.
    • Diagnose and resolve complex production issues across infrastructure, code, and messaging layers.
    • Enhance platform reliability via improved logging, monitoring, alerting, and operational tooling.
    ________________________________________
    Required Qualifications


    • 5+ years of hands-on backend development experience in large-scale, high-throughput environments.
    • Strong proficiency in Java (Java 8+, multithreading, concurrency libraries, performance optimization).
    • Solid understanding of Linux fundamentals (filesystem, networking basics, shell operations, performance tools).
    • Extensive experience with Message Queue systems (IBM MQ, Kafka, RabbitMQ, ActiveMQ, etc.).
    • Deep knowledge of asynchronous programming, non-blocking IO patterns, and event-driven system design.

    Good understanding of modern network protocols, including:
    o gRPC (service-to-service communication, protobuf, streaming patterns)
    o HTTP/2 (multiplexing, header compression, flow control, performance benefits)

    Experience implementing and maintaining CI/CD pipelines and DevOps tooling, including:
    o Jenkins
    o Chef Infra / Chef Habitat
    o Terraform
    o PCF CLI


    • Demonstrated ability to design scalable system architectures and evaluate design trade-offs.
    • Basic understanding of Authentication/Authorization concepts and secure communication patterns.
    • Familiarity with containerization and orchestration (Docker, Kubernetes) is an asset.
    • Excellent debugging, problem-solving, and performance-profiling skills.
    ________________________________________
    Preferred Qualifications


    • Experience in financial services, real-time scoring, risk systems, or other low-latency domains.
    • Exposure to observability stacks (Splunk, Prometheus, Grafana, ELK).
    • Knowledge of DevOps practices, automation, and additional IaC tools.
    • Hands-on understanding of reliability engineering (circuit breakers, retries, backpressure, failover strategies).
    • Ability to lead complex technical initiatives and drive cross-team alignment.
