Fractional Cto Jobs in Renton, WA (NOW HIRING)

Build the technical core of a new business at Amazon scale. Amazon is externalizing the supply chain that moves billions of units a year, and turning it into a set of services any business in the world can plug into. We call it Amazon Supply Chain Services (ASCS).

It is Amazon's own supply chain, now available to help businesses of all types and sizes transport, warehouse, distribute, fulfill, and deliver goods across first, middle, and last-mile touchpoints with the flexibility to adopt one, some, or all services. Fulfillment, warehousing, distribution, transportation and shipping, offered the way AWS offers compute. It is one of the largest greenfield opportunities at the company, and the Solutions Architecture team sits at the center of it.

When a business decides whether and how to run their supply chain on Amazon, you are the person who designs the answer, builds the proof, and earns the trust that closes it.
This is not a role where you hand off a diagram and walk away. You own the end-to-end technical design of how a customer's commerce stack, their storefront, OMS, WMS, middleware, and APIs, connects to Amazon's supply chain network, and you can build the integration, not just draw it. You are the trusted technical advisor in the room with their CTO and VP of Engineering, the passionate tinkerer who stands up a working proof of concept to de-risk the hard part, and the builder whose reusable patterns make the next engagement faster for the whole team.
We are early

The portfolio is expanding and the hardest, highest-value engagements stitch multiple supply chain services together. (Your customer might import via global logistics into upstream warehousing, then inject into Amazon's fulfillment network for retail and off-Amazon channels at once). You will help define what "good" looks like for this practice as it scales, not inherit a finished playbook.

If you want to be the technical field CTO of a business this size, this is the seat.
You will be expected to quickly understand technical architectures; research, build, and deliver proof-of-concept solutions; speak to builder patterns and practices with fluency; and convert work-in-progress into launched, production-ready business outcomes. As part of the SA community you will capture and share best practices, generate internal and external technical content, and grow the practice around you. This role involves up to 25% travel, including customer site visits, industry conferences, and team meetings at various locations.
Key job responsibilities
Serve as the trusted technical advisor to businesses, owning the end-to-end design of solutions that connect their commerce stack to Amazon Supply Chain Services, and advising senior customer leaders (CTO, VP of Engineering, enterprise architects) on how to achieve performance at scale.
Architect and build integrations across the ASCS portfolio - work hands-on with REST and GraphQL APIs, SP-API, EDI, OAuth, webhooks, and data mapping; produce sample code; and stand up working proof-of-concepts to validate the approach before scaling.
Own the reasoning behind design trade-offs and evaluate architectures to identify and remediate issues.
Run technical discovery and produce architect-level deliverables: technical and complexity assessments, integration design documents, solution architecture diagrams, POC code, and runbooks.
Own the full engagement lifecycle - requirements scoping, pre-sales technical feasibility and objection handling, phased onboarding, and post-launch monitoring and steady state - to a hard production-ready bar.
Collaborate with customers, partners, product, and engineering to shape the future of ASCS offerings, and translate what you learn in the field into clear requirements that influence the product roadmap for the customer relationships you own.
Capture and share best practices, and build reusable, peer-reviewed technical content (reference architectures, accelerators, sample code, guides) that make the whole team faster.
