Software Engineer III

Location: Fully Remote - US Only

Duration: 6-months with possible extension/conversion

Pay Rate: $85/hr on W2

Benefits: Medical, Dental, Vision; Paid vacation/Sick leave

Job Overview:

The Software Engineer will support a strategic data platform and tooling migration initiative, transitioning business-critical operations from a third-party SaaS CRM (Salesforce) onto an internal ORM framework data platform with custom AI-native tooling built on top. The engineer will design and build tools on top of data pipelines, full-stack web applications, and integrations between systems, while leveraging AI-assisted development workflows to accelerate delivery. Work spans backend data modeling, ETL/streaming pipelines, frontend application development, and CRM platform integration and CRM Tooling.

In this role, you’ll work at the intersection of full-stack engineering, data platforms, workflow automation, and developer productivity. You’ll design and build internal applications, real-time data systems, and platform tooling that support high-impact operational workflows across out client’s ecosystem.

This is an opportunity to help redefine how internal software is built — leveraging modern frameworks, event-driven systems, and AI-powered development tooling to accelerate delivery and improve operational scale.

Job Responsibilities:

• Design and implement scalable entity and object schemas within a custom ORM-style data platform, similar to GraphQL-backed or domain-driven architectures
• Build and maintain distributed real-time data pipelines using technologies such as Kafka, Pulsar, Kinesis, or similar event-streaming systems
• Lead migration and integration efforts from Salesforce into Meta’s internal tooling ecosystem, including:
• Custom objects
• Workflow automation
• Triggers and validation rules
• Reporting and operational tooling
• Develop modern full-stack applications using React, Next.js, TypeScript, and API-driven architectures
• Leverage AI-assisted engineering tools such as Cursor, Claude Code, and GitHub Copilot to accelerate implementation, refactoring, debugging, and code quality
