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
