Jobbeschreibung

Hi! Were EMCD - a rapidly growing ecosystem of crypto products, including a Wallet, P2P platform, mining pool, cloud mining, and more. Our mission is to empower people to use money for creation, not survival.

With over 7 years on the market and active international expansion, were now launching a new strategic direction focused on building the next generation of mining infrastructure.

About The Team

Performa is a financial infrastructure platform built for entrepreneurs and companies that need fast, secure, and simple international transactions. We remove the bureaucracy of traditional banking and the chaos of the crypto world by bringing multi-currency accounts, payments, FX, payroll, and partner services together in one unified interface. No waiting. No hidden conditions. No unnecessary complexity. Your finances - under control. Your business - growing.

What you will work on:

• Building a ledger system to track all client funds (inflows/outflows).
• Integrating on-ramp/off-ramp providers.
• Integrating with a custodial service provider.
• Integrating with HR systems.
• Developing a payroll system for large-scale payouts in both crypto and fiat.

We're looking for a Senior Backend Engineer who will help us design, build, and evolve the core services powering our NEO-BANK.

What you will do:

• Develop the service responsible for internal balances and money movement (holds, debits, refunds, internal transfers, ensuring the correctness of all ledger entries - the numbers must always match).
• Integrate the core with internal processing systems and the adapters interacting with blockchains (designing and implementing communication protocols: APIs, events, queues, statuses).
• Participate in architectural discussions for services and integrations (thinking ahead about how the system will evolve and scale, understanding reasonable trade-offs, and helping find the right balance between ideal architecture and practical delivery).
• Work closely within a team that combines processing and core engineering: joint planning, participating in code reviews, and driving improvements in architecture, code quality, and development processes.

What we are looking for:

• 3+ years of experience in backend development.
• Tech stack: Go, PostgreSQL, Kafka, gRPC, RESTful APIs.
• You write clean, maintainable code and value tests and code reviews.
• Youre comfortable working with existing systems: you know how to carefully refactor and reduce technical debt - not just rebuild everything from scratch.
• Mandatory: experience with systems involving money, balances, transactions, or similarly complex business logic.

What we offer:

• Remote-first culture work from anywhere;
• Competitive compensation in USD/USDT;
• Flexible schedule and a result-driven approach;
• Opportunity to lead and build high-load, global-scale systems;
• A team of professionals in blockchain and fintech;
• Growth opportunities in both technical and leadership tracks.
