BigCommerce’s mission is to help merchants sell more at every stage of growth, from small startups, to mid-market businesses to large enterprises. We focus on being the best ecommerce platform so our customers can focus on what matters most: growing their businesses.

We are equally passionate about growing our employee’s careers and providing them an incredible experience as we rapidly expand across the globe. We are proud to have been recognized numerous times for our product and workplace culture. We empower our people and customers to build, innovate and grow, so together we can redefine the ecommerce industry.

BigCommerce is disrupting the e-commerce industry as the SaaS leader for fast- growing, mid-market businesses. We enable our customers to build intuitive and engaging stores to support every stage of their growth.

We’re hiring a Senior Product Marketing Manager who blends the best of classic PMM skills—positioning, messaging, go-to-market—with a deep understanding of the partner ecosystem. You’ll own how we tell the story of BigCommerce’s product value in partnership with our ISVs, agencies, and SIs—and play a critical role in how we go to market, land deals, and expand our footprint. This is a role for a strategic storyteller, cross-functional influencer, and ecosystem evangelist who knows that customer success doesn’t happen in isolation—it happens when the right technologies and teams come together at the right time.

What You’ll Do:

• Own end-to-end messaging and positioning for key product lines, especially those where partners are core to customer success

• Craft high-impact narratives that articulate how BigCommerce + Partner = Accelerated value (1 + 1 = 3)

• Lead and execute go-to-market strategies for product launches, ecosystem integrations, and joint solutions

• Be the master of your domain—the go-to internal expert others seek for clarity, content, and confidence

• Partner with Sales, Solution Engineering, Alliances, and Product to ensure alignment across messaging, enablement, and pipeline strategies

• Develop solution briefs, sales tools, playbooks, and co-branded materials that explain not just what we do—but how we win together

• Understand the partner sales cycle—and know when to bring in the right ISV, agency, or GSI to tip the deal

• Influence our roadmap and packaging by capturing partner feedback and mapping it to customer needs

• Contribute to thought leadership and analyst content that positions BigCommerce as a best-in-class ecosystem platform

• Help build repeatable, scalable ways to position and launch joint offerings and integration stories across channels

Who You Are:

• 5+ years of product marketing experience in SaaS or commerce, with experience in or adjacent to a MarTech/commerce partner ecosystem

• A strong grasp of how ISVs and services partners accelerate go-to-market and increase win rates in B2B or B2C environments

• A sharp, structured thinker who can turn product features and integrations into differentiated stories

• Equal parts strategist and executor—comfortable crafting positioning and getting your hands dirty writing, building, and enabling

• A hustler and go-getter who can operate autonomously, influence in a matrix org, and drive alignment across teams

• Trusted and credible with Product, Sales, and Partnerships—you know how to earn buy-in and bring people with you

• Passionate about customer outcomes, and how the right ecosystem unlocks scale, speed, and satisfaction

• A clear communicator with strong writing chops, presentation skills, and empathy for your audience

• Curious, coachable, and energized by solving cross-functional puzzle

• Customer Focused - You have a passion for solving real customer needs with technology and talking to them directly as well as through empathetic messaging.

• Personable - You are seen as positive and energetic, and you exude a strong sense of teamwork by working effectively, respectfully, and efficiently with all team members.

• Proactive - You not only manage assigned tasks/projects on time, you independently deliver ideas, perspectives, and deliverables that improve our competitive positioning and perspective on the market.

• Ethical - You believe in our mission, share our values and understand that it’s not just about what you get done, but also how you do it.
