Cloud Solution Architect

Role Summary

We 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 Responsibilities

Cloud 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 Serverbased 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 247 reliability

Minimum 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
