Senior Implementation Engineer

About the role

This is the role for the person who makes our most complex customers successful. As a Senior Implementation Engineer, you own the hands-on, end-to-end delivery of Katana for our highest-value and most technically demanding accounts - the multi-channel, multi-location merchants whose inventory and manufacturing operations are too intricate for a standard setup. From technical discovery and system architecture through integrations, data migration, configuration, and go-live - you are the person in the system making it work. You are not advising from the sidelines. You build the integrations, map the workflows, migrate the data, and get customers live with confidence. Inventory and manufacturing operations are in your DNA - you understand how real merchants move product, plan stock, and fulfil across channels - and you're equally at home in the systems that surround Katana: Shopify, WooCommerce, accounting, shipping, and EDI, connected through native connectors, APIs, and middleware. And you're comfortable reaching for AI - you use tools like Claude to build working solutions, scripts, and accelerators that get customers live faster. This is how the whole team works. These are the implementations that cannot afford to slip. You own them. This is a high-touch, customer-facing role. You'll be live with customers for much of the day - running implementation and pre-sales calls, checking in proactively, and handling direct support on the accounts you own. The technical implementation is the heart of the work; you just deliver it in constant dialogue with the customer, not heads-down on your own. To be clear about the rest of the scope: this isn't a project management role - you're not coordinating a build from a spreadsheet, you're in the system doing the work. It isn't a training or enablement role either; customer education and ongoing adoption are owned by Customer Success, and you own the technical implementation that makes those conversations possible. And it's not a role for someone who has only advised on implementations. We want the person who built them and got customers live.

Additional Information

About Katana Katana is a remote-first, AI-first SaaS company building powerful inventory and manufacturing software for 1,500+ businesses that make and sell physical products around the world. We've just stepped into an exciting new phase of expansion - moving from smaller merchants into a larger market of modern, multi-channel, multi-location businesses. With that growth comes bigger opportunities, more complex problems, and the chance to shape how we scale. Our 100+ person team across 10+ countries is building what's next - together. And that's where you come in. This is the rare role where you own the hardest problems outright and your work shows up at scale. Katana is taking on bigger, more complex customers than ever, and you'll be the person who gets their implementations live - then turns what works into the solutions, tooling, and playbooks the wider Solution Engineering team builds on. Work that sits right against revenue, and is unmistakably yours. Impact at scale. High-value, complex accounts carry outsized revenue and reference value. You're the person who protects that revenue, and the solutions you build don't stop at one customer; they scale the whole team. This isn't quiet background work - it's revenue-enabling, and it's seen. Real ownership. You own the hardest implementations end-to-end, and turn what works into the reusable solutions, tooling, and playbooks the rest of the team adopts. Scope, ownership, and a direct line of sight to revenue and product. The interesting problems. Multi-system, multi-channel, multi-location merchants with genuine operational complexity - Shopify, WooCommerce, accounting, shipping, EDI, dirty data and multi-level BOMs - worked across a modern API and integration stack plus AI delivery tooling. Not cookie-cutter setups. This isn't a role for someone who wants a bigger version of the job they already have. It's for the builder who wants their work to matter at scale - and to be seen for it - rather than write a spec for someone else to build. If you want to build something, not maintain something, this is the rare seat where you actually can.
