Enterprise Engagement Manager in Cambridge

The Role

We're hiring an Engagement Manager to own how Proton shows up inside a distribution business: scoping the work, designing the solution, and running the engagement from kickoff through go-live and beyond.

Different from a normal implementation role, a lot of what you'll deliver doesn't exist yet.

You'll work with customers on new use cases, new integrations, sometimes entirely new products.

You'll figure out what we should build with them, not just how to configure what's already there.

In practice you're a forward-deployed product manager: you find what's needed in the field, shape the solution, and drive it back into the product.

You'll work directly with customers, often their executives, to understand how their business runs and what would actually move the needle.

You need to be credible on both sides of the table: the business case and the technical reality of an ERP integration.

This is a fit for someone who thinks like a product person — clear about the real problem, opinionated about the right solution, and focused on whether the customer gets real value.

You might come from professional services, solutions, delivery, consulting, product, or a startup.

What matters is that you've owned ambiguous problems end to end and been on the hook for the result.

You don't need to write code.

We use AI heavily as a working tool, and we'd love to hear how you've used Claude or another model to do your own work better.

What You'll Do

• Scope implementations and own the solution design: what to build, what to configure, what to push back on.
• Partner with customers on new use cases, new integrations, sometimes entirely new products, defining what we should build.
• Run engagements from kickoff through go-live, then into adoption and expansion.
• Work with our forward-deployed engineers to deliver integrations, data pipelines, and platform connections.
• Own the customer relationship up to the executive level: set expectations, flag risk early, keep their leadership confident as work plays out.
• Drive adoption after go-live and find ways to expand the account.
• Bring what you learn in the field back to Product to shape the roadmap.

What We're Looking For

• 5–8+ years owning ambiguous, customer-facing problems end to end in professional services, solutions, consulting, product, or a startup.
• A product mindset. You find the real problem, separate must-haves from nice-to-haves, and you're energized by building something new.
• Comfortable making the case to a VP or C-level buyer.
• Technical aptitude and the appetite to go deeper. You can talk through APIs and data flows, but you don't need to write code.
• A history of owning delivery, not just the recommendation.
• Comfort with ambiguity. When scope changes mid-engagement, you re-plan and keep going.
• Real experience using AI tools (Claude or similar) in your work, with specifics on how.
• Low ego, high ownership. This function is still being built, and you'll help build it.
