Solutions Architect (Delivery)

About Extend:

What you’ll do:

• Lead post-sales technical implementation conversations with merchants, conducting deep technical discovery to understand their systems, integration architecture, and constraints — and translating findings into a clear path forward.
• Own the technical onboarding experience, serving as the primary technical point of contact from kickoff to go-live, partnering with internal Engineering and Product teams to identify and address any product gaps and ensure integrations are set up for long-term success.
• Establish and maintain technical documentation for merchant onboardings — system architecture diagrams, API inventories, and integration specs — that cross-functional partners rely on throughout the merchant lifecycle.
• Build and maintain a library of reusable integration assets — templates, configuration guides, and onboarding playbooks — that improve consistency and reduce time-to-live across the merchant portfolio on the Solutions team.
• Lead investigation and resolution of complex post-onboarding technical issues, collaborating with Engineering and Support to drive root cause analysis and communicate findings clearly to internal and external stakeholders.
• Own pre-launch QA — including sandbox testing and end-to-end validation of integration flows — ensuring integrations meet a high technical bar before go-live.
• Identify and champion AI and automation opportunities that improve operational efficiency, partnering with internal teams to move initiatives from idea to execution.

What we are looking for: 

• 4-7 years of experience in a customer-facing technical role such as a Solutions Architect, Implementation Specialist, Technical Consultant, or similar client-facing position.
• Demonstrated track record of independently leading clients or stakeholders through complex technical implementations or integrations, from scoping through go-live.
• Exceptional ability to translate complex technical concepts, architecture, and solutions for both technical and non-technical audiences — including executive stakeholders.
• Deep, hands-on experience working with Mid-Market and Enterprise merchants, with the ability to manage competing priorities across multiple accounts simultaneously.
• Strong working knowledge of web technologies and integrations, including hands-on experience designing and troubleshooting RESTful API integrations, and a solid understanding of how Javascript, HTML, and CSS interact within a production environment.
• Hands-on experience with common integration patterns (APIs, file-based, event-driven, webhooks, etc.) and the ability to recommend the right approach for a given use case.
• A proactive, ownership-driven mindset — you identify problems before they escalate, drive solutions end-to-end, and advocate for both the client and the business when tradeoffs arise.

Nice to Haves:

• Proficiency with Postman or similar API testing and debugging tools, ideally in a client-facing or cross-functional troubleshooting context.
• Experience configuring or supporting back-office OMS/ ERP systems (like Netsuite) in a client context.
• Experience with eCommerce platforms (e.g., Shopify, BigCommerce, etc.) and a practical understanding of how they integrate with broader business systems such as ERPs, OMS platforms, and third-party services.

Salary Range:

• Expected Pay: $110,000 - $160,000* Base Salary and Commission annually for On Target Earnings (OTE)

*This role may be filled at multiple levels. Final title and compensation will be determined based on the candidate’s experience, skills, and business needs.

Life at Extend:

• Working with a great team from diverse backgrounds in a collaborative and supportive environment.
• Competitive salary based on experience, with full medical and dental & vision benefits.
• Stock in an early-stage startup growing quickly.
• Generous, flexible paid time off policy.
• 401(k) with Financial Guidance from Morgan Stanley.
