Virtual Asset Payment / API Engineer vs Web3 Security Engineer: Salary & Career Benchmarks in Brazil

In Brazil, Web3 Security Engineer roles typically command a higher median salary than Virtual Asset Payment / API Engineer positions. According to our 2026 live benchmark data, a mid-level Web3 Security Engineer earns a median salary of R$26K, whereas a Virtual Asset Payment / API Engineer brings in roughly R$22K (a gap of R$4K at the median).

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

Virtual Asset Payment / API Engineer demand is high, particularly in Brazil's fast-growing fintech and capital-markets sector, led by employers such as Nubank and Stone, building the payments and trading infrastructure behind Pix and Brazil's instant-payments ecosystem. Web3 Security Engineer demand is high, concentrated in Banking, fintech, and GCC security teams, led by employers such as Itaú Unibanco and Google Brazil, hiring web3 security engineers to meet Banco Central do Brasil (BACEN) and LGPD (Lei Geral de Proteção de Dados) compliance obligations.

Workspace flexibility significantly impacts total compensation value in Brazil.

Virtual Asset Payment / API Engineer roles score 60% on our remote-friendliness index (High). This is because platform and systems work is largely asynchronous and tool-driven, and Brazilian fintechs have kept these roles hybrid or remote to compete with global fintech pay scales. Where in-office attendance is required, it is typically driven by trading-floor proximity and release-window coordination still pull specialists into the office, and BACEN-regulated firms in São Paulo tend to formalise this into a fixed hybrid schedule.

Web3 Security Engineer roles score 60% (High). Investigation and hardening work is largely tool-driven and asynchronous, and Brazilian security teams have kept São Paulo-based roles hybrid or fully remote to compete for scarce talent against US and European employers paying in stronger currencies is the primary driver of flexibility. When office days are required, it is usually for incident response drills and regulator-facing audits still pull teams into the office, and BACEN-regulated banks in São Paulo tend to formalise this into a fixed two- or three-day hybrid schedule rather than leaving it to team discretion.
