- Plan, write, and operate newsletters for relevant audience segments.
- Build a distinctive, reliable social presence and adapt strong ideas intelligently across formats.
- Own the blog calendar and personally write, commission, or edit technical explainers, points of view, customer stories, product announcements, and use-case content.
- Interview researchers, engineers, customers, and partners to create accurate, compelling material.
- Research search demand and competitive results, identify areas where HASH can earn authority, and create high-quality SEO briefs and content clusters.
- Improve website and landing-page copy, calls to action, and conversion paths.
- Build and maintain marketing automation, segmentation, lead scoring, instrumentation, and reporting.
- Create useful sales-enablement material and keep it current.
- Brief and prioritize the Senior Brand Designer’s work across posts, email, campaigns, decks, reports, and case studies.
- Measure activation, qualified audience growth, organic discovery, inbound demand, and sales influence, and adjust the program as evidence warrants.
Requirements
- Exceptional writing and editing skills, with a portfolio demonstrating clarity on complex ideas.
- Hands-on ownership of several areas including lifecycle email, newsletters, technical content, social distribution, SEO, product marketing, or marketing operations.
- Ability to build automated journeys, segments, and measurement independently.
- Strong editorial judgment and understanding of attention-earning content.
- Commercial awareness without an overly promotional approach.
- Ability to learn unfamiliar technical subjects, identify core ideas, and maintain accuracy while improving explanations.
- Thoughtful use of AI and automation for leverage, while retaining responsibility for all published claims.
- High agency and ability to sustain a demanding cadence without sacrificing quality.
- Experience with enterprise AI, data infrastructure, developer tools, simulation, analytics, or other technical B2B products is useful.
