Job Title

Role SummaryWe are seeking an experienced Cloud Solution Architect (CSA) with deep expertise in integration-heavy, high-volume systems. The CSA will be responsible for designing, stabilizing, and modernizing cloud-based architectures that meet business, technical, security, and performance requirements.This role requires a hands-on architect who can take technical ownership of an existing Platform Science ↔ SQL Server ↔ Custom Application integration built on Windows services, AMQP queues, and SQL stored procedures, stabilize current operations, and design a future-ready, scalable architecture.You will collaborate closely with client stakeholders (Operations, Application Delivery, Integration Engineering) and internal delivery teams (Engineering, Business Analysts, PMO) to drive performance, reliability, and long-term architectural improvements.Key ResponsibilitiesCloud Architecture & Design- Design end-to-end cloud architectures across IaaS, PaaS, and SaaS platforms. - Build scalable, secure, and highly available solutions on Azure, AWS, or GCP. - Define cloud architecture blueprints, reference architectures, and design standards. - Evaluate cloud-native services and recommend fit-for-purpose solutions aligned with business needs.Ownership & Stabilization- Take ownership of the existing Windows service + SQL Server–based integration consuming and producing messages with Platform Science using AMQP/RabbitMQ or equivalent messaging systems. - Perform structured code and architecture reviews covering: - Windows services / worker services - Queue consumers and producers - SQL schemas and stored procedures - Configuration and deployment setup - Publish findings with prioritized remediation plans. - Diagnose and eliminate performance bottlenecks, including: - Queue backlogs and thread starvation - Database locking and missing indexes - Long-running or inefficient stored procedures - Define and track SLOs for latency, throughput, and reliability. - Implement observability using metrics, logs, traces, dashboards, and alerts.Modernization & Future Architecture- Propose and design a scalable, event-driven architecture, including: - Multi-consumer worker models - Partitioning strategies - Back-pressure handling - Retry mechanisms, circuit breakers, and resiliency patterns - Evaluate and implement middleware platforms as needed (e.g., MuleSoft, Boomi, or open-source stacks) for standardized integration, orchestration, and governance. - Define API contracts, schema evolution strategies, and versioning practices. - Implement CI/CD pipelines and automated integration, contract, and load testing for services and database components. - Ensure enterprise-grade security and compliance, including: - Authentication and authorization - Secrets management and least-privilege access - Data masking for PII/PHI - Audit logging and operational runbooks to support 24×7 reliabilityMinimum Qualifications- 12+ years of experience in software engineering, with 5+ years designing and architecting large-scale, integration-heavy systems. - Strong hands-on experience with: - .NET (C#) – Windows Services or Worker Services - AMQP / RabbitMQ (or Azure Service Bus, Kafka) - Microsoft SQL Server – schema design, T-SQL, indexing, execution plans, and performance tuning - Proven ability to reduce message latency, prevent queue backlogs, and horizontally scale consumers and producers. - Deep understanding of integration and event-driven patterns, including: - Pub/Sub - CQRS / Event Sourcing - Outbox / Inbox - Saga patterns - Idempotency - Practical experience implementing: - Observability (Application Insights, Prometheus, Grafana, ELK) - CI/CD (Azure DevOps, GitHub Actions) - Automated testing (contract, integration, and load testing) - Excellent communication and stakeholder management skills, with the ability to translate operational challenges into actionable technical solutions.Nice to Have- Experience with telematics, logistics, or high-throughput real-time systems - Exposure to Platform Science or similar fleet/driver workflow platforms - Multi-cloud architecture experience
