Jobs at Djinni

Role Overview

This is a hands-on, execution-driven role working directly with the Head of Project. You'll take new projects, tools, and features from zero-to-one — researching them, testing them, and handing them off to whoever will own them long-term. It's not a coordination or people-management role: we need someone energized by figuring out something new, who builds systems and documentation as they go rather than managing a team.

Key Responsibilities

Project Execution

• Drive high-priority projects from brief to delivery
• Manage timelines, dependencies, and priorities across teams
• Track everything in motion and push work to completion
• Flag delays early and resolve blockers without escalation
• Take new projects/features at the zero-to-one stage, research and test them, and pass them to the team that will run them long-term (e.g. testing a new tool integration and building the adoption plan for marketing, or exploring a new monetization platform and rolling out a usage plan)

Systems & Documentation

• Build documentation and lightweight SOPs for the specific tools and initiatives you research, and hand them to marketing
• Create scalable operational frameworks
• Identify bottlenecks and fix them with systems, not manual workarounds
• Launch new projects in Notion from scratch and keep them structured, accurate, and visible

Execution Support

• Translate priorities into clear plans with owners and deadlines
• Coordinate across departments as needed to ensure alignment and follow-through — without managing them
• Support growth, monetization, and automation initiatives
• Deliver concise research and actionable summaries

Documentation

• Maintain clear, usable process documentation
• Build a knowledge base that scales with the team

Requirements

Must Have

• 4+ years of experience in R&D, Operations, or similar roles
• Strong Notion expertise (non-negotiable) — a real builder: project tracking or a personal dashboard with live metrics, not just a Knowledge Base/Wiki
• Comfortable using AI tools and automation — mandatory
• Experience building and documenting processes for new tools or initiatives
• Excellent communication skills in English (C1 and above)
• Ability to manage multiple priorities in a fast-paced environment
• Strong organizational and problem-solving skills

Nice to Have

• PMP or equivalent certification
• Automation tools (Make, Zapier, etc.)
• Experience in media, affiliate, or performance marketing
• Familiarity with ClickUp, Airtable, or Google Sheets

We're looking for someone who:

• Is proactive and takes ownership
• Thinks commercially and solves problems independently
• Is energized by figuring out something new rather than running something established
• Thrives in a fast-paced environment
• Pays close attention to detail
• Is eager to grow alongside the company
• Doesn't need or want a people-management track — this role stays hands-on

What We Offer

Professional Growth

• International and multicultural environment
• Career development opportunities
• Learning resources and corporate library
• Work alongside a high-performing team
• Access to modern tools and technologies

Benefits

• Competitive salary
• 21 paid vacation days
• 14 paid sick leave days
• Work-life balance
• Team events and activities

Working Environment

• Hybrid — cozy office in Warsaw available whenever you need it
• Complimentary snacks, drinks, and office perks
• Friendly and supportive team
• Comfortable workspace

We look forward to meeting you!
