Senior Integrations Developer (Netsuite & Celigo) – (Contract), UK

About This Opportunity

We are representing a confidential healthcare technology organization in their search for a Senior Integrations Developer to join their UK-based team on a contract basis. This is a hands-on, integration-heavy developer role where you will own the build, maintenance, and evolution of business-critical integrations across NetSuite, Celigo, WMS platforms, and internal systems.

This role offers real business impact: when integrations are healthy, fulfilment runs smoothly; when they are not, you will be the person who diagnoses failures and designs lasting fixes. Our client is open to hiring at a higher level for the right candidate, given how business-critical this work is.

Responsibilities

• Own and improve integration flows connecting proprietary platforms, Celigo, NetSuite, and WMS systems
• Build, test, and deploy integration changes with a focus on reliability, maintainability, and safe rollout
• Develop and support NetSuite integration components, including RESTlets and SuiteScript that improves integration robustness
• Troubleshoot integration failures end-to-end, addressing data issues, API behaviours, platform configuration, and edge cases
• Implement fixes that address root causes and prevent recurrence of issues
• Improve engineering quality across integrations through consistent patterns, clear documentation, and careful handling of retries, idempotency, and partial failures
• Collaborate across time zones with teams primarily based in Australia, aligning on priorities and communicating progress clearly in writing
• Support core fulfilment data flows including order-to-fulfilment status synchronisation, inventory updates and reconciliation between NetSuite and WMS, and shipment confirmations across systems

What We're Looking For

Essential Experience:

• Deep, hands-on iPaaS integration experience (Celigo strongly preferred)
• Strong understanding of APIs and endpoints, including real-world experience with authentication, payloads, error modes, and rate limits
• Strong working knowledge of NetSuite integrations, including RESTlets
• Proven ability to debug integration issues end-to-end and implement fixes that prevent recurrence
• Experience building and supporting multiple production-grade integrations with examples of complex flows you have owned (multi-system sync, robust error handling, retries, reconciliation, and clear recovery paths)
• Build-to-last mindset with focus on maintainable code and configuration, clear handoffs, and future-proof design
• Comfort working in fast-moving environments where priorities can evolve and ownership is expected

Highly Desirable:

• SuiteScript experience, especially where it supports integration reliability
• Experience integrating with WMS platforms and fulfilment or inventory workflows
• Interest in building technology in regulated or healthcare-adjacent contexts

Working Arrangements:

• This role is based in the UK and works closely with teams largely based in Australia, so some collaboration may happen outside standard UK hours to maintain overlap
• Remote or hybrid options available
• Incident handling during agreed support windows (expectations will be aligned during the hiring process)
