Senior Marketing Manager

San Francisco, CA -- Hybrid (3 days a week in downtown SF office)

About Billables

Billables AI is building the AI-powered operating layer for professional service firms, and we're starting where the pain is deepest: the legal industry. Our platform automates the manual overhead that slows lawyers down, bringing together intelligent timekeeping, work activity capture, and operational visibility so firms can understand how work happens and build a more efficient, profitable practice. The best work happens when people aren't buried in administrative burden, and that's exactly the problem we're solving.

Named Legal Tech Company of the Year by Law.com in 2026, Billables AI is one of the fastest-growing companies at the intersection of AI and legal technology. Our team brings together expert AI researchers and veteran startup builders who know how to move fast, build with conviction, and deliver software that sits at the core of how our customers work and generate revenue. Based in San Francisco, we empower everyone on the team to drive meaningful work end-to-end.

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.

What You'll Work On

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
