GoMining has been building Bitcoin mining infrastructure since 2021. Today, our data centers provide around 1.5% of global BTC mining output.

Our core product is digital miners — assets backed by real mining equipment in our facilities. This makes mining accessible, transparent, and profitable for users worldwide, regardless of technical knowledge or investment size.

As the crypto industry becomes mainstream, we developed a new B2B integration tool:

a loyalty engine that works like “perpetual cashback” for retail customers.

How the product works

• A customer purchases a premium product: jewelry, gadget, car, travel package, etc.
• Together with the purchase, the customer receives a digital miner (embedded in the receipt or provided as a gift).
• The miner starts generating daily BTC rewards directly to the customer’s wallet.

This gives partners:

• A strong competitive advantage,
• A higher-value product offering,
• Long-term customer retention based on continuous BTC accruals.

We are looking for a highly skilled B2B Sales Manager who can build a systematic pipeline of brand partnerships across global markets.

The role combines strategic business development, creative deal-making, and cross-industry expansion.
