Principal Platform Product Manager - Billing & Authentication

At Constant Contact, we are seriously awesome people who take ownership and make an impact by operating with the mindset, integrity and courage of a small business owner. There’s something so profoundly rewarding about knowing that your work is empowering people everywhere to pursue their dreams. Here, we all play an integral part in helping business owners, entrepreneurs, non-profits and individuals to succeed by giving them all the help and tools they need to grow online. We’re energized by new challenges and new possibilities-and we’re just getting started!

We have an opening for a Principal Platform Product Manager to lead the definition of Constant Contact’s core services, with particular focus on authentication and billing. These are the services every product we ship is built on: how a customer signs in, what their plan lets them do, and how what they use turns into revenue. You will set the direction for them, decide what we build and in what order, and define how they should behave so the teams that depend on them can move quickly and trust the result.

The first job is billing. We are moving from an in-house billing system to Stripe Billing, and hundreds of thousands of small businesses count on us getting it right. Alongside it, we are modernizing identity: sign-in, single sign-on, and the account and access model behind them. As those stabilize, the scope of this role grows with the business. Entitlements, account structure, partner and reseller models, and whatever core service we need next are all fair game for someone who has earned the trust to take them on.

You will partner with our Billing Infrastructure and Growth & Enablement engineering teams and with Security, and work closely with Finance, FP&A, RevOps, Support, Sales and our Growth PMs.

Success in this role looks like a clean move to Stripe, an identity platform that is simple for customers and safe for the business, and core services the rest of the company can build on without waiting on you.

The ideal candidate has real depth in how money moves through a subscription business, is technical enough to shape engineering decisions, and has the range to take on platform problems well beyond billing.

What You’ll Do

• Lead the Definition of Core Services: Set the vision and multi-year roadmap for the shared services every product depends on, starting with billing and identity. Define how each service should behave, what we build, in what order and why. Engineering owns delivery; you own what “done” means and whether we have met it.

• Own Billing & Payments Strategy: Set direction for subscriptions, plans and pricing, invoicing, payment methods, payment recovery, refunds and account changes. Decide the sequence and make the trade-offs explicit.

• Define the phasing, success metrics, acceptance criteria and sign-off bar for our migration from an in-house billing system to Stripe Billing. Set the testing, rollback and control expectations from day one. Every customer should come through without noticing.
