Job description

About the Company

Our client is a behavioral science company built around a rigorous, research-backed method for helping people make better decisions about how they live and work. Their framework sits at the intersection of values, aptitudes, and economically viable interests — and it shows up across digital assessments, live experiences, certifications, and a growing suite of products serving both individuals and organizations. With over 250,000 users globally and eight products in market, they operate with the intellectual seriousness of a think tank and the pace of a high-growth startup. The company is profitable, expanding, and deeply committed to the people it serves.

About the Role

This is the role responsible for how the company's thinking sounds. As Lead Content Writer, you will become the primary voice of the brand across every content surface — from marketing copy and product language to newsletters, workbooks, and editorial content. You will work closely with the founder and leadership team, absorbing the company's methodology from the inside and translating it into writing that is warm, precise, and intellectually honest. The company is launching new assessments and companion products throughout 2026, and this writer will be central to how those products show up in the world. This role reports directly into senior leadership and is fully onsite in Manhattan five days a week.

Key Responsibilities

• Own the brand voice across all content formats, ensuring consistency, clarity, and alignment with the company's methodology and tone
• Write high volumes of content daily across email, newsletters, landing pages, product and assessment copy, workbooks, scripts, social content, and presentations
• Collaborate directly with the founder and product and marketing teams to translate complex behavioral science concepts into accessible, compelling language
• Edit and elevate AI-generated content, maintaining the standard of voice, rigor, and human tone the brand demands
• Support product launches by developing all associated content from go-to-market copy to in-tool language and onboarding materials
• Contribute to the development of new assessment content, archetypes, and framework-based writing as the product suite expands
• Attend product meetings, classes, and internal sessions to stay embedded in the company's thinking and ensure writing reflects current methodology
• Build the foundation for a scalable writing function as the team grows

Qualifications

• Exceptional writing ability across multiple formats, with a portfolio that demonstrates range, rigor, and voice
• Genuine fluency with complex ideas — particularly around human behavior, careers, psychology, or purpose-driven frameworks — and the ability to translate them without losing intellectual honesty
• A prolific, fast writer who can sustain high-volume output without sacrificing quality
• Background in editorial, media, or content-intensive environments with demonstrated in-house experience — publications such as HBR, The Atlantic, Wired, Fast Company, the Washington Post, or equivalent are strong signals
• Digitally native and experienced with AI writing tools, with a clear point of view on how to use them while preserving the voice that makes writing worth reading
• Fully available to work onsite five days a week in Manhattan — this is a non-negotiable requirement
• GTM or marketing sensibility is a meaningful plus — writers who understand how content connects to conversion add significant value in this environment
• Familiarity with wellness, personal development, psychology, or purpose-driven media is an asset
