Founding Product Marketing Manager

Plain is redefining customer support for the next generation of B2B companies. We're building the fastest, most powerful platform to help companies move beyond reactive support and build true customer relationships.

Some of the world's most forward-thinking companies, like Cursor, Ashby, and Sanity, trust Plain to unify all customer interactions, enable faster team collaboration, and supercharge their workflows with AI.

We're a small, tight-knit crew with offices in SF and London. This role is hybrid – 3 days a week in our SF office. We tend to start our days earlier (think 7:30/8 AM PT) so we get real-time overlap with our colleagues in Europe.

Why this role is special

You'll be Plain's founding PMM at a moment when the category is wide open. The product is proven, the customers are here – and when people discover Plain, they love it. Now we need more of the right people to discover it.

What you’ll do

Plain has product-market fit, a roster of standout customers, and a category-defining narrative waiting to be told. What we're missing is the person to tell it – consistently, clearly, and in a way that creates urgency before anyone gets on a sales call.

You will:

• Define and own how Plain talks about its product – across existing features and every launch to come

• Build the narrative around every product launch and make sure it translates into pipeline, not just page views

• Arm the sales team with what they need to win – battle cards, competitive positioning, and objection handling scripts

• Own the solutions and features pages so that the right buyer immediately understands why Plain is built for them

• Talk to customers to get a pulse on what parts of the product they love and write case studies, product pages, etc. that champion those customers

• Collaborate deeply with our Support Team to understand why they love the product and what customers love too

• Turn Plain's modularity and composability into visible proof – case studies, templates, use-case storytelling that makes the product feel obvious before a prospect ever gets on a call

This is a great fit if you…

• Bring proven product marketing experience at a B2B SaaS company with a technical or developer-adjacent buyer

• Write with sharpness and specificity – you can take a complex product and make it feel inevitable

• Have built sales enablement materials from scratch and have seen them actually change how a team sells

• Sweat the details on craft – you know when something is on-brand before you can articulate why

• Think across creative mediums. Whether it’s video, written content, interactive demos, you know which format serves the story best

• Thrive in early-stage environments where the brief isn't always fully formed

• Are excited to work cross-functionally with Product, Support, Customer Success, and Sales

This won't be the right role if you…

• Are uncomfortable with ambiguity. We have some really exciting traction but are still at an early stage and are constantly learning and trying new things as our company grows.

• Need established playbooks and clearly defined processes before you can move.

• Aren’t excited to jump into the details of the product. This is a role that requires you to have a high aptitude for every feature and be able to talk about them individually and how they role into a full platform

• Aren't energized by the idea of being the first person in this function at a company that's still being built.
