Seniority, tech stack, and location all move this gap. Senior practitioners in either discipline can exceed the upper range through specialist skills. See the skills premium section below for the specific certifications and tools that push offers to the top of the range.

While both positions are vital to a modern tech organisation, Virtual Asset Payment / API Engineer and Web3 Security Engineer have fundamentally different daily workflows.

Virtual Asset Payment / API Engineer focuses primarily on building APIs and infrastructure that connect crypto and virtual-asset platforms to fiat payment rails, exchanges, and custody providers. Day-to-day work revolves around building and securing APIs that bridge crypto exchanges or wallets to fiat banking rails, integrating with custody and liquidity providers, and implementing the transaction monitoring required for virtual-asset licensing.

Web3 Security Engineer focuses on securing blockchain infrastructure, wallets, and the systems that connect them to traditional finance, distinct from smart contract auditing but closely adjacent to it. Their time is spent securing node infrastructure and custody systems, reviewing wallet and key-management architecture, responding to on-chain security incidents, and working with smart-contract auditors on integration security.

Transitioning between these two paths is achievable but requires targeted upskilling.

Neither path requires starting from scratch. Professionals in both roles share underlying technology fluency; the gap is usually domain knowledge and specific tooling rather than core engineering fundamentals.

In Poland in 2026, both roles are seeing demand, but with different drivers.

Virtual Asset Payment / API Engineer demand is high, particularly in Warsaw's banking and fintech sector, home to Poland's largest domestic banks and a fast-growing payments industry, led by employers such as ING Bank Śląski and PayU. Web3 Security Engineer demand is high, concentrated in the global business services centres and shared security operations hubs that global banks and insurers run out of Kraków and Wrocław, led by employers such as Orange Polska and T-Mobile Polska.

Workspace flexibility significantly impacts total compensation value in Poland.

Virtual Asset Payment / API Engineer roles score 60% on our remote-friendliness index (High). This is because much of the work depends on proximity to trading desks or on-call banking infrastructure, a norm that Poland's IT sector has broadly kept in place thanks to the widespread B2B (umowa B2B) contracting model, which gives both employers and specialists more flexibility than a standard umowa o pracę. Where in-office attendance is required, it is typically driven by trading-floor proximity and same-room incident response, which larger employers with a Kraków or Wrocław global capability centre are more likely than smaller Polish software houses to formalise into a fixed hybrid schedule.

Monitoring, tooling, and investigation work is largely dashboard-driven and portable, a norm that Poland's IT sector has broadly kept in place thanks to the widespread B2B (umowa B2B) contracting model, which gives both employers and specialists more flexibility than a standard umowa o pracę is the primary driver of flexibility. When office days are required, it is usually for incident response war rooms and cross-team security reviews, which larger employers with a Kraków or Wrocław global capability centre are more likely than smaller Polish software houses to formalise into a fixed hybrid schedule.
