Growth Engineer
About Us
Mechanism builds profitable companies and turns them into enterprises. Since 2019, we’ve launched and scaled 10 companies while driving $200M+ in revenue by treating company-building as an engineering problem, not an art project. We combine rigorous validation, advanced analytics, and repeatable systems to dramatically increase the odds of success. Today, we are pushing that model further: building an operating system for entrepreneurship that allows us to launch profitable, reinvesting companies with speed, precision, and minimal waste. This role sits at the center of that system. The Role The Growth Engineer owns growth for HeySunday. HeySunday is not just another brand in the portfolio. It is one of Mechanism’s two profit companies, and it helps fund the rest of the operating system. The profit from HeySunday gives us room to launch new companies and keep building for the long term. This means you are responsible for growth and the work that goes into it. You will set the strategy, manage the channels, run the experiments, understand the math, and make the calls on where we push, where we cut, and what we try next. This is not a role for someone who wants to hand paid media to an agency and check in once a week. It is not for someone who wants to stay high-level while someone else is inside the accounts. It is for someone who wants to sit at the center of our growth engine, be hands-on daily, and have real impact. Most of your time will be spent on HeySunday, roughly 80%. The rest will be spent on focused growth work across other Mechanism companies. That is part of what makes the role interesting. You will see more business models, more constraints, and more growth problems than you would inside one company, then bring those lessons back to HeySunday. What You Own You are accountable for: HeySunday’s full growth engine including: strategy, prioritization, and outcomes Paid acquisition on Google Ads and Meta Ads at scale Connected TV and Broadcast Ads SKU testing CRO across landing pages and funnels The growth model that defines assumptions, targets, and constraints Profitable revenue measured in ROAS, CAC payback, and contribution margin You are not responsible for: Inventory management Cash management or P&L ownership Customer support General operations People management or direct reports What You’ll Do Own paid acquisition end-to-end at HeySunday, including strategy, channel mix, budget allocation, and the day-to-day work inside Google Ads and Meta Ads Manager Be in platforms daily, not just reading dashboards Design, run, and read a high-cadence SKU testing program. Double down on what works and kill what doesn’t Build and own HeySunday’s growth model and reporting layer Direct Mechanism’s engineering, design, and creative teams to ship landing pages, ad creative, and funnel changes faster than any in-house team could on its own Use AI and automation to compress cycle time by creating auto-pausing rules, LLM-generated creative variants, attribution scripts, and automated reporting Spend roughly 20% of your time embedded in other Mechanism portfolio companies on time-boxed growth engagements Codify what works into reusable playbooks, scripts, and automations that compound across the portfolio Provide clear, written updates on results, learnings, and blockers on Mechanism’s standard cadence Who You Are This role is for someone who has led growth, but never got too far from the work. You are likely a fit if you: Have run meaningful budget through Google, Meta, or other paid acquisition channels Know how to connect campaign performance back to unit economics, contribution margin, and profitability Believe the best growth leaders are still operators, not just managers of operators Think in systems, not just campaigns Care deeply about unit economics and profitability Want exposure to a portfolio of companies without being spread thin Are comfortable making clear calls with imperfect information Experience Required 6+ years in performance marketing Deep, current hands-on experience running Google Ads and Meta Ads at material scale Track record of profitable scale in DTC or e-commerce Hands-on experience with SKU testing, landing page optimization, and CRO Technical fluency - you’re building in Claude Cowork, used GA4, built living dashboards, or shipped scripts to automate parts of your workflow First-principles thinking and bias to action where you ship in hours and days, not weeks Strong written communication and instinct for tight, evidence-based reporting Comfort leveraging AI, automation, and modern growth tooling Time Commitment This role is full-time and will need to overlap with US ET for the majority of the workday. It is an exciting opportunity that demands a level of dedication beyond the standard 9 to 5. We need someone who's willing to go above and beyond to help us achieve our ambitious goals, and who's eager to put in the effort to make a real impact. Location US-Based - Fully remote.
