Easyship is a leading multi-carrier shipping software platform serving over 100,000 brands globally, providing access to 550+ courier services across 200+ destinations. The company is expanding its enterprise customer base and needs a Technical Implementation Lead to own end-to-end implementations of complex integrations.
In this role, you will be the technical expert and single point of accountability for enterprise implementations, from pre-sale discovery through go-live and handover. You'll lead technical discovery sessions with enterprise customers, mapping their eCommerce platforms, ERPs, OMS, and WMS systems to validate product fit. You'll design solutions covering API architecture, endpoints, webhooks, authentication, and data mapping, then bring customers to agreement on a clear recommendation.
You'll scope and sign off Statements of Work for every deal requiring API, custom app, or customization work, covering deliverables, go-live dates, forecast volumes, and support terms. You'll resolve technical questions from customers and internal teams, reproducing issues in Postman or Insomnia and diagnosing root causes in requests, responses, and logs. You'll lead technical kick-offs and calls with customers' technical and senior teams, partner with Solutions Developers to align on scope and design, and manage multiple implementations simultaneously from signature to go-live and volume migration.
You'll own implementation escalations, including recovery plans when volume falls short of forecast, and lead structured handovers to Customer Success and Support. You'll maintain governance on custom builds, document recurring questions, and feed product gaps to Product and Engineering with clear business cases. This is a technical role first—you'll be the go-to API expert for customers, Sales, and internal teams.
REQUIREMENTS:
- 5+ years in technical implementation, solutions architecture, or similar technical customer-facing role, including enterprise SaaS implementations
- Expert, hands-on command of REST APIs, webhooks, and integration patterns, including OAuth 2.0, SSO, and API keys
- Fluency with JSON, data mapping, and SQL; confident using Postman or Insomnia
- Structured troubleshooting across HTTP status codes, rate limits, error handling, retries, and logs
- Understanding of how eCommerce platforms, ERPs, and warehouse systems integrate with shipping services
- Confidence with technical and non-technical senior stakeholders; ability to form and communicate recommendations
- Experience writing SoWs, running multiple implementations, and holding scope and pricing boundaries
- Effective use of AI: reviewing agent-generated work and translating it into plain language
- Excellent technical documentation skills and strong written and verbal English
- Bonus: Python or JavaScript; logistics or eCommerce experience; Shopify, Squarespace, Celigo, or Zapier implementations; prior Easyship experience
