Founding Marketer

Weave (YC W25) is building the definitive platform for understanding and improving how engineering teams work. We believe the way engineering output is measured today is fundamentally broken and that modern AI can give teams a far more accurate and actionable view of productivity, impact, and collaboration.

Trusted by 200+ customers including Robinhood, Rho and Browserbase, we've delivered consistent double-digit month-over-month revenue growth since May and are looking to accelerate.

We've raised a $13.5 million Series A and are backed by Standard Capital, YCombinator, Moonfire, Burst Capital, IrregEx and the Agent Fund.

As Weave's Founding Creative Marketer, your job is to make Weave feel inevitable. You will turn Weave into the brand the best engineering teams in the world default to.

What We’re Building

Weave is rethinking engineering output from first principles.

We use AI to:

• Understand how engineers actually work (not just what they ship)

• Surface meaningful insights about productivity, quality, collaboration and impact

• Help teams improve outcomes without vanity metrics or surveillance

Our goal is not to optimize for “more output,” but for better engineering.

The Team You’ll Work With

You’ll work directly with:

• Andrew (CTO) – previously a founding engineer at Causal, MIT alum. Andrew has been in your shoes and is deeply committed to providing the mentorship, ownership and growth he had as an early engineer.

• Adam (CEO) – leads sales and customer discovery. Adam is a former sales executive at multiple high-growth startups and deeply embedded with customers and scaled multiple sales teams from $0-30M in ARR.

This is a small, intense, highly collaborative team. You will have real ownership from day one.

The Role

This isn't a traditional marketing role and we're not looking for a traditional marketer. The closest thing we can describe it as is a mashup of product marketing manager, content engineer, creative director, and video producer.

You'll be responsible for shaping the product story, writing the words, running launches, designing the graphics, and shipping campaigns. We launch tier-1A products on a cadence most companies can't match, and we want every launch to feel inevitable by the time it ships: primed by content, sequenced across channels, and impossible to ignore.

This is a rare opportunity to take real ownership over launches that move the business. Not to assist on someone else's strategy, not to optimize a slice of a funnel, but to own the thing end to end and be measured on whether it drove pipeline, signups, and brand. If you've been waiting for the role where you actually get the keys, this is it.

Responsibilities

• Own launches end to end. Plan, sequence and ship tier-1 product launches. From positioning and naming to the launch video, the LinkedIn thread, the landing page, the customer quotes, and the follow-on content that keeps it alive for two weeks instead of two days.

• Build the creative. You're the one making the assets, not just briefing them. Launch videos, ads, landing pages, blog graphics, demo edits, social cuts. You can take an idea from concept to shipped asset without waiting on a freelancer.

• Build the content engine. Write and edit posts, threads, blogs, case studies, and launch collateral that get shared bay people we want as customers. You'll be both the writer and the editor, pushing the bar on every piece that goes out.

• Run the growth playbook. Design, run, and measure experiments across organic social, paid, SEO, lifecycle, partnerships, and community. Kill what doesn't work, double down on what does.

• Partner with product. Sit in the room when we're scoping the next release. Push back on launches that won't land. Sharpen the ones that will.

• Build the brand. Weave should feel like the obvious choice for the best engineering teams in the world. You're the person making sure every touchpoint reinforces that.

• Be flexible. Some days you'll be writing copy, others you'll be in Premiere or Figma, briefing a podcast guest, or wiring up an attribution pipeline. We're inventing the function as we go.

Qualifications

Must-Have

• Proven track record on launches. You've helped launch content that drove pipeline and you can show us the receipts.

• You've gone viral on on X and LinkedIn, repeatedly. Not "a post did well once." You've repeatedly produced content that broke out and you can explain why it worked.

• You write exceptionally well. Not just "good for a marketer." You can write a LinkedIn post that gets shared, a blog post that gets cited and a launch announcement that makes engineers stop scrolling.

• You have product taste. You can tell the difference between a launch that's worth the effort and one that isn't, and you can articulate why.

• You move fast and own outcomes. You don't wait for a brief. You write the brief, ship the thing, and report on what happened.

• You care about developer tools. You don't have to be an engineer, but you have to genuinely care about the audience: what they read, what they share, what they roll their eyes at.

• This role is 5 days in office in SF

Nice-to-Have

• Experience at an early-stage startup (Seed to Series B), even if it wasn't a marketing role

• Background marketing developer tools, AI/ML platforms, or infrastructure software

• Editorial or journalism background. You've worked somewhere where the bar on writing was high.

• You've shipped a product yourself, run a side project, or worked closely enough with engineers to think like one

• You've run your own newsletter, YouTube channel, or creator account that grew on the strength of the work
