HCM - SEO/GEO Associate Intern (FTE track) - Vietnam

About TinyFish

TinyFish is the production web layer that lets AI agents search, read, extract, authenticate, and act on the live web. We are a Series A startup building the infrastructure layer for the agentic web. Our marketing team is small and fast-moving, and this role works directly with our SEO/GEO Manager.

The Role

This is a full-time, paid internship position that requires working from the office. You will own our in-house off-page, distribution, and technical SEO operations — the work that grows TinyFish's non-branded organic reach — and support SEO/GEO research alongside the Manager.

This is a hands-on operating role, not a strategy-only one. You'll run recurring channels week over week, keep our technical foundation clean, and feed research that shapes what we build next. It's a full-time internship on a defined track to convert to a full-time role after 6 months based on performance.

GEO note: Throughout this JD, "GEO" refers to Generative Engine Optimization — optimizing so that AI assistants and LLMs (ChatGPT, Perplexity, Claude, AI Overviews, etc.) surface and cite our content. As a company building for AI agents, getting discovered by AI is a first-class goal here, not an afterthought.

We'd rather tell you what "great" looks like than just list tasks.

By the end of month 3, you will have:

• Taken full ownership of our content syndication and distribution channels, running them on a predictable cadence

• Stood up a reliable backlink and AI-visibility tracking routine the Manager can trust without re-checking

• Completed at least one full technical SEO audit cycle and shipped fixes (or queued them with the dev team)

By the end of month 6 (conversion review), success means:

• A measurable lift in non-branded organic reach and referring-domain quality

• Demonstrable AI/LLM visibility for priority topics (citations, mentions, or AI-referral traffic trending up)

• A clean, monitored technical baseline: structured data valid, indexation healthy, no unresolved crawl blockers

• You operating channels independently, with the Manager reviewing direction rather than execution

• Syndicate and repurpose our content across Medium, Substack, dev.to, Hacker News, and relevant subreddits — adapting format and framing per platform rather than copy-pasting

• Manage directory and listing submissions (product directories, AI/agent tool listings, developer catalogs)

• Track and monitor backlinks — new links, lost links, link quality — and flag opportunities and risks

• Repurpose existing assets for both organic search and AI discovery

• Support strategic link-building and proactive brand-mention campaigns

• Run recurring technical audits (crawl errors, broken links, redirects, site architecture)

• Implement and verify structured data / schema (JSON-LD) across page types

• Maintain and QA metadata at scale

• Check client-side rendering and indexation across the site and escalate issues

• Partner with the dev/web team to scope and verify fixes

• Query, keyword, and competitor research to inform what we publish and optimize

• Pattern validation for programmatic SEO at the research stage — testing whether a template/page pattern is worth building before we invest

• AI-visibility tracking: monitor how TinyFish appears in LLM answers and identify optimization opportunities

• Improve already-indexed posts for both traditional search ranking and AI retrieval (refreshing content, internal links, metadata, and semantic structure)

• How off-page and technical SEO actually move non-branded organic growth for a technical B2B product

• GEO/AEO in practice — structuring and marking up content so LLMs and AI assistants surface and cite it

• Hands-on fluency with Google Search Console, GA4, Ahrefs/Semrush, Screaming Frog, and GEO-tracking tools

• How to run technical audits, schema implementation, and dev-team collaboration end to end

• How emerging metrics like AI referrals and chatbot/LLM impressions sit alongside classic SEO KPIs

• The inner workings of a Series A go-to-market motion in the AI-agent / developer-tools space

1. Foundational SEO — solid on-page plus basic technical, and a working understanding of how off-page and links function. 0–2 years, or self-taught with a portfolio we can look at.

2. Strong written and verbal English — you'll write for public platforms and coordinate with the dev team.

3. Detail-oriented and disciplined — genuinely comfortable owning recurring operational work and keeping it consistent.

4. Comfortable with spreadsheets and data, and either know or are eager to learn GSC, GA4, Ahrefs/Semrush, and GEO-tracking tools.

5. Genuine curiosity about AI agents and developer tools — we're a technical product, and the best work here comes from people who find that interesting.

6. Available full-time for the duration of the internship.

A note on fit: This role rewards people who like owning channels and getting things done over people who want a comfortable, low-ownership seat. If recurring operational discipline and "ship it, then improve it" energize you, you'll thrive here.

1. Hands-on directory submission or content syndication experience

2. Working knowledge of HTML, schema/JSON-LD, and rendering concepts

3. Prior exposure to GEO/AEO

4. Familiarity with developer/AI communities (dev.to, Hacker News, dev-focused subreddits)

5. Familiarity with user-centric optimization, PostHog and A/B testing tools for conversion rate optimization

6. Comfort building lightweight automations/workflows (e.g. n8n) to scale repetitive SEO tasks

• Ownership of real channels from week one — not shadowing, not slide decks

• Direct mentorship from the SEO/GEO Manager and exposure to a Series A GTM team

• A clear, performance-based path to a full-time role after 6 months
