Jobs at Djinni

We are a team in the iGaming industry. Our goal for this year is to launch and scale our own SEO department, focusing on creating and developing a network of content projects and satellites across international markets.

This position is for someone who has outgrown the role of a regular Senior Specialist and is looking for complete freedom of action. We do not offer a seat in a rigid corporate system filled with endless approvals and micromanagement. We are looking for an individual who will build processes from scratch, assemble a team, and head a fully-fledged SEO department.

Important: We are ready to consider strong candidates from classic e-commerce, B2B, large-scale content projects, or media. If you know how to handle high data volumes, process automation, and link building, but haven't worked in iGaming yet, we will help you get up to speed with the vertical's specifics quickly.

## What We Offer (Your Freedom Zone):

* Carte blanche on decisions: You choose the tech stack, software, contractors, and internal SEO strategy to achieve KPIs.

* Building a department: An opportunity to hire link builders, developers, and content managers to meet your goals.

* Zero bureaucracy: Direct dialogue with the project investor/owner. Fast budget allocation for necessary software and website promotion.

* Top-tier conditions: A stable fixed salary (discussed individually based on the interview results) + KPI bonuses. Paid in USDT.

What You Will Do:

* Develop and implement a comprehensive strategy for rolling out and promoting a network of websites from scratch.

* Build an efficient content creation pipeline (implementing automation tools, AI prompting, and setting up localization workflows).

* Fully manage the department's link building strategy: from link profile quality control to finding new high-authority backlink sources.

* Hire, onboard, and coordinate your team.

What We Look For in a Candidate:

* 2–4 years of SEO experience in a Senior or Team Lead position.

* Deep understanding of technical SEO: scaling project networks, backlink profile management, and routine process automation.

* Proficiency with standard analytical software (Ahrefs, Screaming Frog, trackers, anti-detect browsers).

* Experience managing promotion and link building budgets, as well as evaluating their ROI.

* Prior experience in iGaming is a plus, but a systematic product mindset and the ability to build processes are our top priorities.
