About the role

• Software Developer developing Java services in a distributed architecture for Telesat's satellite solutions. Focus on implementing microservices and resiliency in Azure.

Responsibilities

• Develop, and maintain Java (Java 17+) services within a distributed, event-driven architecture using Spring Boot.
• Implement asynchronous workflows and event processing using Azure Service Bus and Event Hub where appropriate.
• Package, deploy, and operate microservices on Kubernetes using Helm across multiple environments (dev/test/prod).
• Contribute to service decomposition, domain boundaries, and API design with a focus on latency, throughput, reliability, and backward compatibility.
• Implement reliable service-to-service communication using REST, gRPC, and messaging protocols.
• Support protocol-agnostic ingress suitable for long-lived or reconnect-sensitive traffic.
• Help optimize networking concerns (TCP behavior, connection pooling, backoff, circuit breaking) for high-scale traffic.
• Contribute to multi-region resiliency design, including regional failover/failback mechanics, validation steps, and automation guardrails.
• Embed production readiness into services: SLIs/SLOs, golden signals, standardized observability, failure-mode analysis, and post-incident architectural corrections.
• Participate in and improve end-to-end readiness drills: failure scenario walkthroughs, runbook execution, and post-drill improvements.
• Design for resilience via health checks, fault management, monitoring, rate limiting, bulkheads, and recovery-on-failure patterns.

Requirements

• Hands-on microservices development in Java 17+ with production Spring Boot experience.
• Experience building distributed, highly available, fault-tolerant systems supporting high-volume concurrent transactions.
• Knowledge of Kubernetes, Docker, and Helm for container orchestration and deployment.
• Understanding of event-driven architectures integrating with message brokers (Azure Service Bus; Event Hub experience is a plus).
• Security fundamentals in distributed systems: OAuth2/OIDC/JWT, SSL/TLS certificates, secrets/certificate handling (Vault or equivalent).

Benefits

• Equal opportunity employer
• Best candidate experience possible with required accommodations
