About the Role

Part senior growth marketer, part data scientist, part applied-AI builder - you turn the way elite marketers think into the data models, metrics, and schemas that power Shadow's intelligence layer. The majority of your time (roughly 75%) is spent on the product: designing the metric logic, data schemas, and analytical models Shadow's agents reason with, and working directly with marketing teams to translate what they actually do into structure the product can act on.

The remaining time (roughly 25%) is spent on measurement of live media programs - guiding incrementality testing, power analysis, and MMM work, and partnering with Paid Media and Growth Strategy to turn test results into budget decisions.

This is for someone who's spent years in the work and now wants to lean into the technology - leveraging hard-won marketing experience to build, not to manage accounts. The product side of this role is not client-facing; the measurement side is internal-facing too, working through Darkroom's own media teams rather than owning client relationships directly.

What We're Building

We're empowering small teams with technology that makes it easier to market and grow businesses. Our current focus is to help consumer brands shift from "workflow automation" to "agent management" within their marketing operations. Shadow is the AI coordination layer - providing shared AI memory, centralized agent control, and model orchestration for marketing teams.

The Agency Behind the Product

Shadow is built alongside Darkroom - a performance marketing agency that's been operating for 10 years, employs 100+ people, runs 100+ clients at a time, and has worked with over 1,000 consumer brands. That's our edge: Shadow isn't a generic AI wrapper; it's a decade of real campaign tradecraft being codified into a system. Darkroom is both our proving ground and our first user. This role plugs directly into that knowledge and turns it into product.

What You'll Own

Product

• Design the analytical models and metric logic the agent reasons with - contribution margin (CM3), acquisition truth (aMER, NCAC), cohort LTV/payback, ad spend efficiency and marginal-return analysis, incrementality testing (geo lifts, conversion-lift, MMM calibration) - from raw platform data to decision-ready insight.
• Define the schemas that encode marketing tradecraft: how creative, channel, financial, and customer data connect into a queryable picture of a brand.
• Own accuracy and judgment - what's load-bearing vs. noise, where attribution lies, how to compute metrics that survive operator scrutiny.
• Spec the model; partner with data eng to build the pipeline and the AI team to wire it into agent skills.

Measurement of media programs

• Guide incrementality testing strategy across Darkroom's paid media programs - geo holdouts, matched-market tests, and conversion-lift studies - and run the power analysis to size tests correctly before spend is committed.
• Support MMM strategy, vendor evaluation, and model calibration where programs need it.
• Partner with Paid Media and Growth Strategy teams to design tests up front and translate results into clear, executive-ready budget recommendations.

Must Haves

• Ran growth at one or more high-growth DTC / omni-channel consumer brands - you've managed paid media tactically, not just supervised people who did.
• Fluency across the full marketing mix (Meta + Google, plus TikTok, email/SMS, marketplace, organic) - you think in MER/CM/LTV/iROAS, not platform ROAS.
• Real data science chops: SQL + Python/notebooks, statistical reasoning, building and validating metric models against messy real-world data.
• Ability to translate between marketer intuition and rigorous structure - and a strong opinion about which metrics actually matter.
• Hands-on experience designing and interpreting incrementality tests - geo holdouts, matched-market testing, conversion lift - including power analysis/pre-test sizing.
• Experience with MMM, either hands-on or through vendor/partner management.
• Strong written and verbal communication - you can explain measurement tradeoffs and model logic clearly to non-technical executives and marketers.

Nice to Have

• Familiarity with modern warehouse/analytics stacks (BigQuery, dbt) - enough to design schemas and collaborate with eng.
• Agency or multi-brand background (pattern recognition across accounts).
• Built attribution models, forecasting/MMM, or internal analytics dashboards.
• Experience with CDPs, server-side tracking, clean rooms, exposure logs, or other privacy-safe measurement environments.

Culture Fit

• A power AI user. You've embedded AI into every workflow you touch and you think in systems - not one-off prompts, but repeatable structures that compound.
• Entrepreneurial. You don't need much direction to move fast, you pivot when the situation demands it, and what you ship is production-grade, not a prototype you hand off for someone else to finish.

Not the bar: deep data-engineering/infra ownership, or leading day-to-day client relationships. We're hiring for science, judgment, and product craft - not pipeline plumbing or account management.

What It's Like to Work at Darkroom

Darkroom is not a typical agency. We are looking for A players who want to build something great. We move fast, think deeply, and expect every team member to bring insight and rigor to everything they touch. We hold a high bar for performance, creativity, and ownership - but we also support each other relentlessly. No egos, no red tape - just world-class talent building something remarkable.

We believe in autonomy with accountability, truth over comfort, and outcomes over optics.
