Assistant Content Manager Jobs in California (NOW HIRING)

About Harbinger
Harbinger is an American commercial electric vehicle (EV) company on a mission to transform an industry starving for innovation. Harbinger's best-in-class team of EV, battery, and drivetrain experts have pooled their deep experience to bring a first-of-its-kind EV platform to support the growing demand for medium-duty EVs and Hybrids. Harbinger: Familiar Form, Revolutionary Foundation.
The role
Harbinger is telling the story of American-made commercial EVs to fleet operators, dealers, and government buyers - and we need someone to make Harbinger easier to understand, trust, and discover, whether a buyer starts with Google, an AI assistant, an industry publication, or a peer recommendation. As Content & Organic Growth Manager, you'll own the editorial strategy and also do the work.
Reporting to the Senior Marketing Manager, you'll define the content strategy and roadmap, interview subject-matter experts, write and edit high-quality copy, own traditional SEO, pioneer our approach to answer-engine and generative-engine optimization (AEO/GEO), and measure the contribution to qualified demand and pipeline. You'll use AI to move fast without ever compromising our quality bar. This is a hands-on builder role for someone who is equal parts writer, strategist, and SEO/GEO operator.
What you'll own

• Content strategy & roadmap: Build an editorial roadmap based on customer questions, product priorities, search demand, category narratives, sales insight, and business goals.
• Writing & editing: Create clear, differentiated content across web pages, articles, case studies, guides, email, executive thought leadership, sales materials, social copy, ads, and video scripts.
• Subject-matter development: Interview customers, executives, engineers, product, and sales; turn technical knowledge into credible, useful stories.
• SEO strategy & execution: Own keyword and topic research, search intent, content briefs, on-page optimization, internal linking, content refreshes, and metadata for medium-duty EV, fleet electrification, TCO, and incentive terms.
• Technical SEO partnership: Work with Web, Engineering, and agencies on crawlability, indexation, page performance, schema and structured data, redirects, canonicalization, and sitemaps.
• AEO / GEO: Develop a practical approach to visibility in AI-powered search and answer engines (ChatGPT, Perplexity, Google AI Overviews) - citation-worthy content, entity clarity, structured facts, expert sourcing, third-party authority, and ongoing query monitoring.
• Content operations & governance: Own the calendar, briefs, workflow, approvals, CMS publishing, quality standards, content inventory, and selective use of contractors or agencies.
• Creative & community: Partner with our in-house photographer, videographer, and motion-graphics team to turn stories into visual content, and own day-to-day social and community management.
• AI-assisted workflows: Use AI for research, drafting, and repurposing at scale while maintaining original thinking, factual accuracy, brand voice, and human editorial judgment.
• Distribution & repurposing: Partner with Growth, Product Marketing, Comms, Lifecycle, Sales, and Partnerships to extend each asset across channels and audiences.
• Story & messaging: Ladder all content to Harbinger's positioning - 'Familiar Form. Revolutionary Foundation.' - and reinforce our perceptions in the market.
• Measurement: Report on qualified organic traffic, non-brand visibility, AI citations/share of voice, conversions, and content-assisted pipeline; use findings to improve the roadmap.

What success looks like in the first 12 months

• A documented content and organic-growth strategy tied to priority audiences, product themes, and measurable business outcomes.
• A consistent publishing cadence with stronger quality, clearer differentiation, and faster reuse across channels.
• Improved non-brand visibility and qualified organic traffic for priority topics, plus an initial AI-search (GEO) baseline and improvement plan.
• A repeatable subject-matter-expert workflow that produces credible customer, technical, and category content.
• Clear reporting connecting content and organic discovery to conversions, influenced pipeline, and sales usage.

Required qualifications

• 4-7 years in content marketing, editorial, copywriting, SEO, or organic growth in B2B technology or another complex-product category
• An excellent writing and editing portfolio showing clarity, range, and the ability to explain technical subjects
• Hands-on experience with keyword/topic research, content briefs, on-page SEO, internal linking, and performance reporting
• Working understanding of technical SEO and the ability to partner effectively with web developers or specialists
• Practical familiarity with AEO/GEO and AI-search measurement - curiosity and discipline matter more than a mature playbook
• Fluency with tools such as Google Search Console, GA4, Ahrefs, Semrush, Screaming Frog, a CMS, and emerging AI-visibility platforms
• Fluency using modern AI tools for research, drafting, and repurposing
• Based in or able to relocate to the Garden Grove, CA area for on-site work

Preferred qualifications

• Experience in automotive, EV, fleet, transportation, industrial technology, or manufacturing

• Experience managing freelance writers, agencies, designers, or video partners
