Jobs at Djinni

We’re looking for an experienced SEO Link Building Specialist who knows how to build links in highly competitive niches and can consistently deliver high-quality, relevant backlinks that contribute to measurable SEO growth.

This is not a role for someone who only has access to a list of guest-post websites. We’re looking for a specialist who understands advanced link acquisition, can identify opportunities competitors are using, and can secure placements that are difficult to obtain.

What We're Looking For

You should have significant hands-on experience with:

• Link insertions / niche edits on existing, relevant, established pages
• High-quality guest posts and editorial placements
• Competitor backlink gap analysis
• Digital PR and journalist/media outreach
• Resource page and broken-link outreach
• Unlinked brand mention reclamation
• Partnerships and relationship-based link acquisition
• Relevant industry and authority directories
• Linkable asset outreach and promotion
• Evaluating websites based on traffic, topical relevance, authority, link profile, and overall quality rather than relying only on DA/DR
• Experience working in competitive industries such as legal, finance, insurance, SaaS, healthcare, home services, or other high-CPC markets is strongly preferred.

What Matters to Us

Quality over quantity. We are not interested in PBNs, link farms, low-quality guest-post networks, or sites created primarily to sell backlinks.

You should understand how to find and secure links from real websites with genuine organic traffic and topical relevance.

Most importantly, you should be able to demonstrate that your link-building work has contributed to ranking and organic traffic improvements in competitive SERPs.

To Apply

Please include:

1. Examples of competitive websites/niches you've worked on.

2. Examples of actual backlinks or link insertions you've secured (if possible)

    

We're looking for someone interested in an ongoing relationship, not a one-time link package. If you have a strong network, know how to conduct effective outreach, and have a track record of producing results in difficult niches, we'd like to hear from you.
