Built for specialist sectors, multi-jurisdiction structures, and high-compliance environments, we support businesses whose needs go beyond standard banking. We’re selective about who we work with because exceptional service requires focus and commitment. With six international offices, five regulatory licences, and an 83% CAGR over the past three years, we’re scaling rapidly and earning industry recognition along the way — including the Financial Times FT1000: Europe’s Fastest Growing Companies 2026, CNBC UK’s Top Fintech Companies 2025, Wealth & Finance FinTech Awards 2025, and the Business Growth Award from Business Awards UK. Behind it all is a team of ambitious VFXers united by collective ownership, a focus on growth, and a shared passion for solving complex problems. About the Role We’re seeking a detail-driven and highly capable Back-End Software Engineer to join our engineering team and contribute to the core systems powering VFX’s global financial infrastructure. You will work across complex, high-value domains including multi-currency account architecture, payment routing, treasury operations, risk management, compliance workflows, and API-driven client integrations. This role is suited to someone who brings discipline, precision, and a strong engineering mindset. You will thrive if you enjoy building resilient, scalable and secure systems that serve sophisticated clients operating across multiple jurisdictions and regulatory environments. This is an opportunity to deepen your expertise within a regulated FinTech while making a tangible impact across a platform used by global businesses. This role can be hybrid at our office in Portimao or fully remote across Portugal.
