Integrations Developer (Celigo)

About the role (What you'll be doing)

You'll be a hands-on integration engineer owning the build, maintenance, and evolution of fulfilment-critical integrations across NetSuite, Celigo, WMS platforms, and internal systems. This is an integration-heavy developer role with real business impact: when integrations are healthy, fulfilment runs smoothly; when they are not, you will be the person who can diagnose the failure and design a lasting fix.

We are open to hiring at a higher level for the right person, given how business-critical this work is.

What you'll do

• Own and improve integration flows connecting our proprietary platform, 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, where appropriate, SuiteScript that improves integration robustness.
• Troubleshoot integration failures end-to-end (data issues, API behaviours, platform configuration, edge cases) and implement fixes that address root causes.
• Improve engineering quality across integrations: consistent patterns, clear documentation, and careful handling of retries, idempotency, and partial failures.
• Collaborate across time zones with a Systems team primarily based in Australia, aligning on priorities and communicating progress clearly in writing.
• Supporting core fulfilment data flows such as:
  • Order-to-fulfilment status synchronisation
  • Inventory updates and reconciliation between NetSuite and WMS
  • Shipment confirmations and fulfilment updates across systems

What good looks like in this role

• Integrations are dependable, with fewer preventable failures and smoother fulfilment operations.
• When incidents happen, you isolate the cause quickly and restore service with minimal disruption.
• Integration work is easier to maintain over time because patterns are reusable and documentation is clear.
• Stakeholders trust changes because expectations are clear and releases are controlled.
• You move with urgency when it matters, without trading away quality.

About you (Who you are)

• You have deep, hands-on iPaaS integration experience (Celigo strongly preferred), and the ability to become productive in Celigo quickly.
• You have a strong understanding of APIs and endpoints, including real-world experience with authentication, payloads, error modes, and rate limits.
• You have strong working knowledge of NetSuite integrations, including RESTlets.
• You have a proven ability to debug integration issues end-to-end and implement fixes that prevent recurrence.
• You have built and supported multiple production-grade integrations and can point to examples of complex flows you owned (for example multi-system sync, robust error handling, retries, reconciliation, and clear recovery paths).
• Your mindset is a build-to-last mindset: you care about maintainable code and configuration, clear handoffs, and future-proof design.
• You are comfortable working in a fast-moving environment where priorities can evolve and ownership is expected.
• You ideally have SuiteScript experience, especially where it supports integration reliability.
• You have experience integrating with WMS platforms and fulfilment or inventory workflows.
• You are interested in building technology in regulated or healthcare-adjacent contexts.

Practicalities (UK)

• This role is based in the UK and works closely with a Systems team largely based in Australia, so some collaboration may happen outside standard UK hours to maintain overlap.
• We handle incidents during agreed support windows; we'll align on expectations during the hiring process.
