About the Role:

We're looking for a Full-Stack Developer with a strong backend focus and real, hands-on fintech experience - specifically in building crypto exchanges or digital banking products. If you've spent the last few years deep in trading engines, payment flows, or core banking systems, we want to talk.

This is not a role for someone who has worked around fintech. We need someone who has been inside it - building the systems that move money, settle trades, and keep financial data consistent at scale.

What You'll Be Doing:

• Designing and building backend services that power financial operations - payments, ledgers, transaction processing, and compliance workflows
• Integrating with external payment providers, banking APIs, and crypto infrastructure
• Owning complex backend logic while contributing to a React-based frontend when needed
• Ensuring financial data integrity, security, and regulatory compliance across the stack
• Collaborating closely with product and business stakeholders who speak the language of finance

What We're Looking For:

• 2-3+ years of hands-on experience building fintech products - ideally a crypto exchange or digital bank (this is a hard requirement, not a nice-to-have)
• Strong Python backend expertise (Django)
• Practical experience with financial systems: payments, ledgers, double-entry accounting logic, reconciliation
• Experience integrating with external payment providers — APIs, webhooks, payment flows, error handling
• Understanding of compliance-sensitive workflows: KYC, AML, transaction monitoring
• Comfortable with React on the frontend - you don't need to be a UI specialist, but you can own a feature end-to-end
• Experience with relational databases and financial data modeling (PostgreSQL preferred)

What we offer:

📈 Professional Growth opportunities:

• Ambitious goals and interesting projects;
• Regular & transparent performance review and feedback process;
• Possibility for both vertical or horizontal growth (in case you want to try a different path).

😌 Comfortable Working conditions

• Flexible working hours;
• Provision of required equipment;
• Remote working model.

🎁 Benefits program

• 18 paid days off + 2 public holidays;
• Free tax reporting support by our Financial department;
• Help with individual entrepreneurs’ questions and accounting support;
• Financial support and additional days off for various occasions (e.g. marriage, childbirth, etc.);

WHAT WILL HELP YOU SUCCEED IN THE ROLE
 

• Strong hands-on experience with Facebook Ads, especially traffic and post engagement campaigns
• MUST-HAVE: practical experience building funnels in ManyChat (Chatfuel or similar tools will also be considered)
• Experience working with anti-detect browsers such as Dolphin Anty, AdsPower, or similar tools
• Understanding of proxy infrastructure and multi-account traffic environments
• Strong understanding of CPL, CPA, CR, lead quality, and traffic monetization metrics
• Real experience working with grey/black-hat funnels and restricted verticals

• Ability to work without classic Facebook Pixel-based approaches
• Arbitrage mindset with strong analytical thinking and testing culture
• Stress resistance and ability to work under frequent bans and infrastructure instability
• Team-oriented mindset and operational discipline

HOW YOU WILL MAKE AN IMPACT

• Launch, manage, and optimize traffic campaigns in Facebook Ads and Telegram Ads
• Build, configure, and maintain automated ManyChat / Chatfuel funnels for audience acquisition and conversion
• Create and optimize messenger-based conversion flows through Telegram, Discord, WhatsApp, and Instagram Direct
• Design complete social funnels from scratch and continuously improve funnel CR and user flow stability
• Work with “white” traffic entry points (sports, memes, entertainment, news, viral pages, etc.) for further audience redirection
• Configure auto-replies, comment automation, DM sequences, lead capture flows, and audience warm-up scenarios
• Conduct continuous A/B testing of creatives, messaging, hooks, and funnel mechanics to optimize CPL and CPA
• Monitor campaign performance, spend efficiency, lead quality, and conversion metrics
• Manage advertising budgets, scaling logic, daily limits, and profitability of traffic bundles
• Work closely with account farmers and infrastructure teams to maintain campaign stability
• Operate within Meta restrictions using up-to-date bypass and anti-detection approaches for gambling-related traffic
• Monitor bans, ad account risks, and funnel health while maintaining operational continuity
