Hackajob is collaborating with a leading client in the AI space and is looking for experienced Integration Developers to contribute to exciting project-based opportunities — remote, flexible, and built to fit around your existing commitments.

Build and optimise workflows using APIs, webhooks, and real-time data pipelines
Connect and synchronise databases across platforms — e.g. Airtable, Google Sheets, Notion
Ensure reliable, real-time data transfer between systems and services
Troubleshoot and improve data flow consistency, latency, and failure handling
Support integration of automated communication systems — e.g. calling or messaging workflows
What we're looking for
Proven experience working with APIs, webhooks, and system integrations
Hands-on experience connecting SaaS tools, CRMs, and databases
Strong understanding of REST APIs, webhooks, and data exchange formats — JSON etc.
Ability to design robust, fault-tolerant data pipelines
Experience troubleshooting API errors, rate limits, and data inconsistencies
Strong ability to read and interpret API documentation
Portfolio or examples demonstrating complex integrations or data synchronisation systems
English proficiency at B2 level or higher
Why this might be a great fit
Part-time, remote, freelance — fits around existing professional or academic commitments
Work on advanced AI projects and gain valuable experience that enhances your portfolio
Influence how future AI models understand and execute complex system integrations
