Requirements

At GoMining, a General Manager is the end-to-end owner of a business direction, responsible for its strategy, P&L, product, team, and overall results. A GM combines business, product, and operational ownership — setting priorities, managing unit economics, driving execution, and making decisions based on data. The goal is to run the direction as a business and take full responsibility for its growth, profitability, and performance.

We are looking for a General Manager to own Custody & Compliance at GoMining — the business line responsible for how customers move funds into and out of our ecosystem safely, quickly, and reliably.

This is not a traditional compliance role. You will own the entire direction as a business and product — from custody infrastructure and KYC/AML to deposits, withdrawals, Travel Rule, fraud controls, provider relationships, and customer experience.

Your goal is to build a system where compliance protects the company without becoming an unnecessary barrier for legitimate customers.

You will own the strategy, economics, product roadmap, delivery, key metrics, and engineering team behind the direction.

ANTIPOLLUTION, a member of Vasileiadis Group of Companies (V Group), is a leading provider of environmental and waste management solutions across the Eastern Mediterranean, Egypt and the Balkans. Its activities span Port Reception Facilities, Emergency Response Services, Decontamination Services, Renewable Energy, Alternative Fuel Production from Waste and Technology.

The HR Business Partner will support the effective delivery of HR operations across the employee lifecycle, partnering with managers and employees to address people-related needs and support business objectives. The role reports to the Head of Recruitment and covers HR operations, selection, recruitment, onboarding, performance management, HR reporting, compliance, learning & development, and employee engagement.

Key Responsibilities

· Oversee day-to-day HR operations and employee lifecycle activities across the headquarters and the company’s operational facilities.

· Act as a key point of contact for managers and employees, providing day-to-day HR guidance and support.

· Maintain organizational structures, job descriptions, personnel records and HR documentation.

· Support organizational effectiveness and ensure HR processes are consistently and efficiently implemented across the organization.

· Prepare HR reports, dashboards and workforce metrics to support management decision-making.

The Design Team Lead runs the day to day work of our Design Team. There are two sides to it. One is craft, which means keeping the standard of the design work high across every client we serve. The other is people, which means keeping the team organised, supported, and able to do good work without getting stuck.

Most of what the team produces is email and SMS campaign design for ecommerce brands, along with ad images, GIFs, short video edits, and the occasional landing page. You will still design yourself, but the larger part of the job is making sure what goes out is right. You are the person who spots what is not working in a design before the client does, and who explains the fix in a way a designer can act on straight away.

You will work closely with Account Managers, who assign the day to day tasks, and with the designers who carry them out. A good deal of the role sits between those two groups: helping an Account Manager work out what a campaign actually needs, turning that into clear direction for a designer, and saying so when a request does not make sense.

The Design Team Lead reports to the Service Director, and works closely with the other departments at Hustler Marketing to make sure design work is delivered well and on time.
