Implementation Manager

Join our team as an Implementation Manager, where you'll be the customer-facing owner of the implementation plan, work, and outcome. You'll partner with Sales to shape workable solutions, lead the delivery plan from signed agreement through go-live, run stakeholder governance and risk, translate business workflows into a technical plan, drive integration and data work, make go-live real, own implementation outcomes, and build a repeatable motion. This role offers a growth path into an Engagement Manager role driving complex customer engagements.

• Ownership of standard customer engagements from pre-sales solutioning through successful go-live.
• Leading the delivery plan, taking each project from signed agreement through go-live, and keeping every workstream moving.
• Translating business workflows into a technical plan, working with customers and Proton teammates to configure the right workflow, data model, and integration approach.

• Pre-sales judgment. You can turn ambiguous customer needs into an implementable plan, distinguish a requirement from a nice-to-have, surface constraints without creating friction, and protect the path to value
• Data-driven and adaptive thinking. You use project and customer data to decide what needs attention, while staying flexible as details change
• Customer-facing range. You're as comfortable in a warehouse aisle with an operations team as you are running a meeting with senior stakeholders. You'd rather understand the work firsthand than manage by secondhand notes
• High agency and a continuous improvement mindset. You look for the root cause, close the loop, and improve the system rather than just getting through the current project
• Clear communication and calm ownership. You can explain technical tradeoffs in plain language, earn trust quickly, and keep customers and internal teams aligned when things are messy
• Implementation and project-management experience. 2+ years in implementation, technical project delivery, professional services, or a comparable role, with demonstrated ownership of customer outcomes. Early-stage B2B SaaS experience is a plus
• Technical fluency. You can work productively with APIs, integrations, data models, source systems, and configuration. You ask precise questions, identify risk, and can hold your own with customer technical teams and senior engineers
• Excellent execution under real-world constraints. You know how to build and run a project plan, coordinate dependencies, make decisions visible, and move multiple workstreams forward without losing the detail
• Practical use of AI in your own work. You regularly use AI tools to accelerate planning, analysis, documentation, and coordination, and know how to provide context, evaluate outputs, and correct mistakes
• Complex B2B, enterprise, or ERP-adjacent software, with high-frequency users and operational workflows people can't opt out of
• Wholesale distribution, manufacturing, logistics, or another operationally complex industry
• CRM, PIM, eCommerce, order management, or systems-of-record integrations
• Experience delivering AI-enabled workflows in a customer environment, including the trust, correction, and handoff patterns that make them useful
