Founding Growth Engineer

Location: Washington, D.C. (In-person preferred | U.S.-based remote opportunity available) Salary: Commensurate with experienceEquity: Founding Team Package The MissionWe are looking for a Founding Growth Engineer who treats business development like a science experiment. You wont just be "running ads"; you will be building the engine that powers our B2B acquisition. This role is for a builder who can write a Python script to scrape a lead list in the morning, design a high-converting lead magnet in the afternoon, and pivot social strategy based on statistical significance by EOD.Key ResponsibilitiesB2B Product Marketing & Messaging: Translate complex product features into "must-have" value propositions for B2B stakeholders.Channel Orchestration: Own the full-funnel strategy across LinkedIn, X (Twitter), and emerging B2B channels. You will be responsible for rapid-fire testing to find "winners" before scaling.Outbound Infrastructure: Architect and manage high-volume cold email systems. Youll handle deliverability, technical setup, and hyper-personalized copy at scale.Lead Magnet Engineering: Create high-value assets (calculators, whitepapers, or mini-tools) that solve real problems for our target audience.The Growth Lab: Design, execute, and analyze A/B tests. We make decisions based on p-values and ROI, not gut feelings.Influencer & Partner Growth: Identify and collaborate with industry thought leaders to amplify our reach through authentic B2B partnerships.The Technical ToolkitWe dont expect you to be a software engineer, but we do expect you to be highly skilled with data.AI Fluent: You use LLMs not just for writing, but for data cleaning, brainstorming experiment ideas, and automating repetitive workflows.Data Science & Python: You can write basic scripts to automate data collection or connect APIs. You know your way around a Jupyter Notebook or at least can use Python to manipulate CSVs beyond what Excel can handle.Excel/Sheets Wizardry: If you arent using VLOOKUPs, Index/Match, or Pivot Tables in your sleep, this isn't the role for you.Stack Mastery: Experience with the modern growth stack (e.g., Clay, HubSpot/Salesforce, Instantly/Apollo, GA4).Why Washington, D.C.?This is an in-person role, however, we operate with flexibility around remote working periods. We believe that the speed of a startup is determined by the speed of its feedback loops. Being in the room together allows us to whiteboard an experiment at 10:00 AM and have it live by lunch.Who You AreScrappy & Systems-Obsessed: Youd rather spend 4 hours building an automated script that works forever than 4 hours doing a manual task once.Economically Minded: You live in the world of LTV:CAC and payback periods. You understand that in B2B SaaS, the best marketing is a frictionless path to a "Yes" in a credit committee.Visionary: You see the bridge between critical mineral circularity and national security. You can think outside the "standard" B2B playbook to find untapped growth loops.How to Stand OutShow us a side project or a script you wrote to solve a marketing problem.Tell us about an experiment you ran that failedand what the data taught you.Buckstops Operating System (Our Values)At Buckstop, weve traded corporate bureaucracy for high-leverage ownership. We look for individuals who thrive in an environment where AI automates the mundane and human brilliance drives the strategic.Extreme Ownership (The Buck Stops Here): Accountability is our bedrock. You own your outcomes end-to-end, no finger-pointing, no excuses. You proactively solve issues before they escalate and communicate with radical transparency.Engineering Excellence: We insist on the highest standards. We dont just build features; we build transaction-backed systems our customers rely on for multi-million dollar decisions.Operational Frugality: Our moat is our efficiency. We "Defend Every Dollar," keeping operating costs low to ensure long-term market dominance. Wed rather build an automated script than buy an enterprise tool.The Scientists Mindset: Through "Never-Ending Learning" and "Strong Opinions Weakly Held," we move at the speed of data. We make passionate, data-backed cases for our ideas but are prepared to abandon them the moment a better p-value emerges.Time-As-Leverage: Time is our most precious resource. We accelerate decision-making to win, while respecting the personal time that keeps us energized. We trust you to manage your life; we expect you to crush your work.Customer-First Integrity: If a move doesnt create value for the customer, we don't make it. We follow the "Make Grandma Proud" (MGP) rule: we prioritize long-term ethics and professional conduct over superficially compelling deals.Mission-Critical Impact (Planet & Profits): We don't view environmental responsibility and profit as a trade-off. We solve the information gap in the circular economy because ignoring environmental costs is ignoring business costs.Strategic Preparedness: "Who Prepares Wins." We research thoroughly and anticipate obstacles before they arrive. In our world, the most prepared person in the room usually wins the market. recblid qq1j57yahhkqdj98nhhy87ua4xr8m4
