Role Description
We are seeking a Senior Middleware Engineer with deep expertise in enterprise messaging, event-driven architecture, and distributed systems integration. In this senior-level role you will be the technical authority for all middleware platforms across the organisation, owning the design, deployment, performance, and reliability of messaging infrastructure that underpins our mission-critical applications.
You will lead integration strategy across RabbitMQ, Redis, and Azure Service Bus, working alongside development, DevOps, and cloud architecture teams to deliver scalable, resilient, and observable messaging solutions. You will also serve as the primary escalation point for integration incidents and provide technical leadership and mentoring to the wider engineering team.
Qualifications
-
7+ years of software engineering or platform engineering experience, with 4+ years focused on middleware and integration platforms.
-
Demonstrable senior-level expertise across RabbitMQ, Redis, and Azure Service Bus in production enterprise environments.
-
Strong understanding of distributed systems fundamentals: eventual consistency, idempotency, at-least-once vs exactly-once delivery, and the two-generals problem.
-
Experience designing and implementing event-driven microservices architectures and service integration patterns (EIP).
-
Proficiency in at least one primary programming language commonly used for integration workloads: C# (.NET), Java/Kotlin, Python, or Go.
-
Hands-on experience with Kubernetes or container orchestration for middleware workloads (Helm charts, operators).
-
Infrastructure-as-Code experience with Terraform, Bicep, or Ansible for middleware provisioning.
-
Strong observability skills: distributed tracing with OpenTelemetry, metrics with Prometheus/Grafana, and structured logging.
-
Experience with secure middleware configuration: TLS/mTLS, certificate rotation, secrets management (Azure Key Vault, HashiCorp Vault).
-
Proven ability to lead technical initiatives, produce architectural documentation, and mentor engineers.
Requirements
-
Architect, deploy, and operate enterprise messaging and middleware platforms including RabbitMQ, Redis, and Azure Service Bus across development, staging, and production environments.
-
Design and govern event-driven and message-driven integration patterns: pub/sub, competing consumers, dead-letter handling, saga/choreography, and request-reply.
-
Lead performance engineering for middleware: tune RabbitMQ broker configuration, channel and prefetch settings, Redis eviction policies, cluster topology, and Azure Service Bus namespace tiers and partitioning.
-
Define and enforce standards for message schema design, versioning, serialisation (JSON, Avro, Protobuf), and backward/forward compatibility.
-
Implement and maintain High Availability and Disaster Recovery for middleware: RabbitMQ mirrored/quorum queues, Redis Cluster and Sentinel, Azure Service Bus geo-redundancy and paired namespaces.
-
Establish end-to-end observability: distributed tracing (OpenTelemetry), metrics (Prometheus/Grafana), and alerting for queue depth, consumer lag, connection pool saturation, and error rates.
-
Collaborate with application development teams to review integration designs, message flow architectures, and service mesh configurations before production release.
-
Own middleware security posture: TLS configuration, certificate management, RBAC/ACL policies on brokers, Managed Identity authentication for Azure Service Bus, and secrets management.
-
Drive Infrastructure-as-Code adoption for middleware provisioning using Terraform, Bicep, or Ansible.
-
Support CI/CD pipeline integration for automated deployment, configuration, and smoke-testing of middleware components.
-
Lead incident response and post-incident reviews for Severity 1 middleware outages; produce actionable remediation plans.
-
Mentor mid-level and junior engineers; produce architecture decision records (ADRs), runbooks, and operational documentation.
Benefits
-
Competitive salary and performance-based bonuses.
-
Comprehensive health insurance plans.
-
Flexible working hours and remote work options.
-
Professional development opportunities and training programs.
-
Generous vacation and leave policies.
