Full Stack Engineer (US)

The Role

We are looking for full stack engineers to build fast across BJAK's AI Neobank app. This role is for product-minded engineers who can move across frontend, backend, internal tools and customer journeys to turn ideas into working products quickly.

• Build and ship full product features across frontend, backend, APIs and databases.
• Create customer and internal workflows for onboarding, accounts, payments, rewards, travel, FX, support automation, KYC and risk.
• Turn ambiguous product problems into working systems with clean UX and reliable backend logic.
• Work closely with product, design, mobile, backend and AI engineers to launch fast and improve after release.
• Build internal tools and automation that reduce manual work and help teams operate at scale.
• Own your work beyond release: monitor, debug, learn and improve.
