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 Server–based integration consuming and producing messages with Platform Science using AMQP/Rabbit

MQ 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., Mule Soft, 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 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 / Rabbit

MQ (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 Dev Ops, Git Hub 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
