Jobs at BJAK

Build end-to-end AI-native product features across frontend, backend, and model integrations. Design and deploy agent workflows, integrate LLMs, memory, and external tools, and ensure real-time streaming, low-latency interactions, reliability, observability, and robust fallback/recovery. Collaborate with ML, backend, and product teams and iterate based on real-world usage.

Build and ship end-to-end AI features, shaping model behavior and surrounding systems. Design prompts, tools, memory, and agent workflows; convert model outputs into reliable behavior; debug across model, infra, orchestration, and UX; optimize latency, cost, and reliability; and develop evaluation frameworks to measure real-world performance.

Build and maintain a production-grade iOS app using Swift and SwiftUI, integrate AI features via backend APIs and on-device models, design AI UX patterns, optimize performance and battery use, capture user signals for AI evaluation, collaborate with backend and ML engineers, and ensure App Store quality, stability, and production reliability.

Build and maintain a production Android app in Kotlin that integrates AI features (chat, vision, voice). Design AI UX patterns, optimize performance and memory, implement analytics and logging, collaborate with backend and ML teams, and ensure stability, security, and scalability in production.

Own and ship core ML subsystems end-to-end for a proactive, long-horizon AI assistant. Work includes data preparation, training, evaluation, inference, debugging production failures, optimizing for latency/cost/reliability, and mentoring other ML engineers.

Build and productize AI-native systems for a fintech neobank: AI agents, RAG/LLM-powered workflows, tool integrations, and automations for onboarding, KYC, support, risk, CRM and operations. Focus on production reliability, evaluation, guardrails, latency, cost, security and compliance while collaborating with product and engineering teams.

Build and maintain backend services, APIs and workflows for an AI neobank. Support fintech products (payments, wallet, savings, investing, insurance), integrate partners (banks, payment gateways, insurers), design reliable systems for accounts, transactions, reconciliation and notifications, and improve system reliability, observability, security and performance for regulated financial products. Collaborate with product, mobile and operations teams to ship customer-facing journeys.

Build and maintain backend services and APIs for onboarding, accounts, payments, cards, transfers, rewards, FX, KYC and risk flows. Design reliable, secure, observable systems for real customer transactions, integrate with partners and AI services, ensure data integrity and incident handling, and collaborate with product and frontend teams to launch and improve financial products at scale.

Build and productionize AI-native workflows, assistants, agents and automation for a neobank app. Integrate LLMs with product data, APIs and knowledge bases, design evaluation/monitoring/fallbacks, prototype quickly and collaborate with product and ops to improve customer support, onboarding, payments and internal tools.

Build end-to-end customer-facing and internal features for BJAK's AI Neobank app: web flows, backend APIs, admin tools, dashboards and operational systems. Work with product, design, mobile and operations to launch fast, integrate APIs, handle data flows, improve production reliability, use analytics and feedback to iterate, and build tools to reduce manual work.

Build and ship end-to-end product features across frontend, backend, APIs and databases. Create customer/internal workflows (onboarding, accounts, payments, KYC, FX, rewards). Collaborate with product, design, mobile, backend and AI teams. Build internal tools, monitor production, debug and iterate to improve reliability and UX.

Build and ship native iOS features in Swift for an AI-enabled neobank. Design clean user flows for insurance, payments and financial services, integrate backend APIs, improve performance and reliability, use analytics to iterate, and implement on-device AI where it improves UX.

Build and ship native Android features for an AI-enabled neobank app using Kotlin. Implement clean user flows for financial services, integrate backend APIs, improve performance and reliability, and use analytics and on-device ML (TensorFlow Lite) to enhance user experiences. Collaborate with product and design to simplify complex journeys and reduce crashes and loading issues.

Build and ship mobile features for BJAK's AI Neobank across Android, iOS, or cross-platform. Collaborate with backend, design, product and AI teams to deliver onboarding, payments, accounts, cards, transfers, rewards, FX and AI-assisted experiences. Improve app quality via analytics, crash reports and production feedback; own features from problem definition through release and production support.

Design, build and ship native Android features in Kotlin for an AI-enabled neobank; integrate backend APIs and on-device ML, improve performance, stability and UX, collaborate with product and design, and use analytics to iterate on AI-assisted financial experiences.

Build and ship native iOS features for an AI Neobank app, focusing on onboarding, accounts, payments, cards, transfers and rewards. Ensure performance, reliability, secure data handling and great UX; collaborate with product, design, backend and AI teams; own app quality and iterate using production feedback and analytics.

Build and ship native Android features for an AI Neobank app (onboarding, accounts, cards, payments, transfers, rewards). Turn complex financial flows into fast, reliable mobile experiences, own app quality and performance, integrate APIs and secure authentication, and iterate using production analytics and customer feedback.
