As we move upmarket, more of our enterprise customers are integrating with Easyship through our API, custom apps, and tailored builds. We're looking for a Technical Implementation Lead to own those implementations end to end, from pre-sale discovery and a signed Statement of Work (SoW) through to go-live, volume migration, and handover. This is a technical role first. You'll be the go-to expert on the Easyship API for customers, Sales, and internal teams, you'll steer them to one clear solution, and you'll partner with our Solutions Developers to deliver it. You'll sit in our Implementation Services team, within Client Services.

• Leading technical discovery with Enterprise/Strategic Sales, mapping customer systems (eCommerce platforms, ERP, OMS, WMS), data flows, and constraints to validate product fit.
• Owning the solution design for each implementation (architecture, endpoints, webhooks, authentication, data mapping) and bringing customers to agreement on one clear recommendation.
• Scoping and signing off the SoW for every deal that needs API, custom app, or customisation work. Each SoW covers deliverables, go-live date, forecast shipment volume, and support terms.
• Resolving technical questions from customers and internal teams before the sale and during implementation, including reproducing issues in Postman or Insomnia and finding the root cause in requests, responses, and logs.
• Leading technical kick-offs and calls with customers' technical teams and senior stakeholders.
• Partnering with Solutions Developers to align on scope and design, unblock questions during the build, and confirm delivery matches the SoW.
• Managing several implementations at once, from signature to go-live and volume migration, and tracking milestones, risks, dependencies, and change requests.
• Owning implementation escalations, including recovery plans where shipment volume falls short of forecast.
• Leading structured handovers to the CSM and Customer Support.
• Maintaining clear governance on custom builds: what's supported, at what cost, and a register of builds in production.
• Turning recurring questions into documentation, and feeding product gaps to Product and Engineering with a clear business case.
