About the Role

HASH is hiring a Marketing & Communications Lead to own content, lifecycle email, newsletters, social channels, SEO, website marketing copy, and marketing operations. This senior, hands-on individual contributor role involves building the marketing function while operating it, communicating HASH's substance to the right people and encouraging engagement.

Responsibilities

  • Develop a clear positioning and message system for technical, operational, and executive audiences.
  • Own the post-signup experience: onboarding, activation, education, re-engagement, and commercial conversation routes.
  • 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.
  • Experience building an early-stage marketing function and communicating to multiple members of an enterprise buying committee is useful.
  • Excellent written and spoken English is essential.
