About the Role

This is a career-defining opportunity to build the marketing function at a company that's reimagining how lawyers work through the power of AI.

We've hit real traction – and we're bringing on our first dedicated marketing hire to match. As Senior Marketing Manager, you'll own marketing end-to-end: strategy, execution, and everything in between. You'll set the foundation – positioning, channels, content, campaigns, and the systems – that let a lean team punch above its weight, using AI tools as a genuine force multiplier rather than a novelty.

You'll work closely with our founders and go-to-market team, with the latitude to build the function your way and the runway to grow with it as we scale.

• Own marketing strategy and execution across channels – content, paid, email, social, events, partnerships – prioritizing based on what actually drives pipeline and growth
• Build and run AI-augmented workflows for content production, campaign personalization, competitive research, and reporting, so the function scales without scaling headcount
• Develop messaging and positioning that differentiates us, and translate it into copy, campaigns, and sales enablement materials
• Set up and own marketing analytics – attribution, funnel metrics, and reporting that ties activity to revenue
• Partner with Sales and Customer Success to sharpen messaging, lead conversion, retention and growth.
• Manage external vendors, freelancers, and agencies as needed
• Test new channels and tactics quickly, kill what doesn't work, and double down on what does

What We're Looking For / Who You Are

• 5-8 years of marketing experience, with at least some of that at an early-stage startup or in a generalist role where you owned outcomes, not just a single channel
• Real, demonstrated fluency with AI tools in a marketing context – not just "I use ChatGPT to write emails," but experience building workflows (content pipelines, automation, research, personalization) where AI tooling measurably increased output or impact
• Strong writing and editing skills – you can produce or sharpen copy yourself, not just brief someone else to do it
• Data literacy – you're comfortable in analytics tools and can speak to CAC, funnel conversion, and attribution without a dashboard doing the thinking for you
• Comfortable learning new technologies and navigating ambiguity in a fast-growing startup
• Experience marketing to a technical or B2B audience is an asset

We aren't looking for a traditional marketing hire. We're looking for someone who thrives in a high-growth environment and is:

• A team player in the truest sense – you collaborate generously, share wins, and make everyone around you better
• Founder-minded – hungry, resourceful, and resilient
• A creative problem-solver – quick on your feet, proactive, and solution driven
• AI-forward – you're genuinely excited about AI tools, actively seek them out, and use them to sharpen your own workflow and scale your impact
• Data-driven and coachable – you use numbers to iterate, and you welcome feedback
