Senior DevOpsPlatform Engineer

Part-Time Contract Remote Approximately 20 Hours per Week

About the Role

A mission-critical SaaS platform used by approximately 800 flooring businesses to manage leads estimates product selection inventory scheduling installations invoicing and payments is being modernized from a /ASP SQL Server stored-procedure-heavy environment to React TypeScript native PostgreSQL REST APIs and AWS. Much of the initial conversion has been completed using AI-assisted development. The immediate priority is to clean up test validate and safely release the converted system while existing customers remain active.

We are looking for a hands-on Senior DevOps/Platform Engineer who can strengthen the delivery platform observability security and production safeguards required for frequent low-risk releases.
Responsibilities

• Assess the current AWS infrastructure CI/CD pipelines environments deployment process and production risks.
• Improve automated build test security-scanning deployment and rollback workflows.
• Support small frequent releases through feature flags staged rollouts health checks and automated validation.
• Establish safe coexistence between legacy and modern services during the migration.
• Build and maintain infrastructure as code for repeatable auditable environment provisioning.
• Strengthen monitoring centralized logging distributed tracing alerting dashboards and incident-response procedures.
• Define service-level indicators for availability latency error rates database health queues and critical business workflows.
• Help diagnose performance and stability issues involving AWS services APIs PostgreSQL Babelfish and components.
• Support the transition from Babelfish and SQL Server-oriented behavior to native PostgreSQL.
• Review capacity connection-pool timeout retry queue and load-shedding configurations.
• Improve resilience for asynchronous and event-driven workloads using services such as Lambda SQS EventBridge API Gateway Redis and dead-letter queues.
• Implement secure secrets management access controls audit logging vulnerability management backup and recovery procedures.
• Verify that rollback remains safe after application or database writes including backward-compatible schema changes.
• Review AI-generated infrastructure and deployment changes for correctness security maintainability and operational risk.
• Document deployment standards incident procedures environment configuration and operational ownership.
• Partner closely with engineering and product teams with meaningful overlap during US working hours.

Required Qualifications

• At least 7 years of professional DevOps SRE platform engineering or cloud infrastructure experience.
• Strong hands-on experience operating production workloads in AWS.
• Proven ownership of CI/CD architecture automated deployments monitoring incident response and rollback.
• Experience supporting production systems built with React PostgreSQL .
• Strong understanding of:
  • Infrastructure as code
  • Networking DNS load balancing and API gateways
  • Containers and serverless workloads
  • Logs metrics traces alerts and production dashboards
  • Secrets management and least-privilege access
  • Backups disaster recovery and production readiness
  • Database migrations and backward-compatible schema changes
  • Connection pooling capacity planning retries idempotency and failure recovery
• Experience introducing staged deployments feature flags canary releases or blue-green deployments.
• Ability to troubleshoot across application infrastructure network and database layers.

Preferred Qualifications

• Experience with AWS Lambda SQS EventBridge API Gateway Redis CloudWatch and container-based AWS services.
• Experience migrating SQL Server workloads to PostgreSQL particularly through Babelfish.
• Experience with Terraform CloudFormation or similar infrastructure-as-code tooling.
• Experience operating workflow-heavy SaaS involving inventory scheduling invoicing payments or other production-critical transactions.
• Familiarity with OpenTelemetry distributed tracing and structured logging.
• Experience reviewing infrastructure or deployment code generated through Claude Code Codex Cursor or similar AI tools.
• Experience improving engineering platforms for teams releasing daily or near-daily.

What Success Looks Like

During the initial engagement this person will:

• Produce a clear assessment of the current infrastructure deployment risks and release blockers.
• Establish reliable CI/CD and environment-management standards.
• Improve monitoring across the core quote-to-invoice workflow.
• Make deployments smaller repeatable observable and safely reversible.
• Strengthen production readiness for the AI-converted React and PostgreSQL platform.
• Reduce instability associated with Babelfish database connections asynchronous workloads and legacy-modern coexistence.
• Create practical operational documentation the engineering team can maintain after the engagement.

Engagement Details

• Remote part-time contract
• Approximately 20 hours per week
• Regular overlap with the US-based team required
• Initial focus on release readiness and platform stabilization followed by modernization scalability and support for AI-enabled product capabilities
