Lead the visual design language for A1’s AI product across web and mobile. Create design systems, UI components, and visual patterns that clarify dynamic AI content, system states, confidence signals, and complex workflows. Collaborate with product, UX, and engineering teams to deliver accessible, polished designs and implementation-ready specifications. Define standards for loading, error, empty, task, and AI-generated output states while maintaining clarity and consistency in a rapidly evolving environment.

Own the end-to-end UX for an AI assistant across mobile and web. Design task flows, AI state visibility, progress tracking, confirmations, error recovery, and trust-building interactions. Collaborate with product, engineering, and ML teams; conduct usability research; create wireframes, user flows, prototypes, high-fidelity designs, and design-system patterns. Balance simple consumer experiences with complex asynchronous, non-deterministic AI workflows.

The role involves leading design for an AI chat app, shaping user flows, creating prototypes, and refining user experiences based on research and insights.

Build and maintain internal applications, backend services, APIs, databases, integrations, and automation systems for business functions. Translate operational workflows into software solutions, develop AI-powered workflows using LLMs and agents, deploy and monitor production tools, and improve reliability and efficiency while collaborating with non-technical stakeholders.

Design intuitive, polished mobile interfaces for iOS and Android financial applications. Responsibilities include creating wireframes, user flows, prototypes, production-ready UI, design systems, and reusable components; collaborating with engineers and product managers; ensuring accessibility, responsiveness, and platform compliance; and iterating based on analytics, usability findings, and feedback.

Design end-to-end digital product experiences across BJAK’s financial products, translating requirements into user flows, wireframes, prototypes, and polished interfaces. Build scalable design systems, collaborate with product and engineering teams, ensure accurate implementation, and improve usability through data and user feedback across mobile and web platforms.

Build and maintain internal applications, backend services, APIs, databases, and AI-powered automation workflows for business functions. Translate manual processes and operational needs into software solutions, integrate internal and third-party systems, deploy and monitor production tools, and improve reliability, accuracy, usage, and time savings. Collaborate directly with non-technical stakeholders to define requirements and validate solutions.

Build and operate the inference and orchestration backend powering AI interactions across mobile and desktop applications. Responsibilities include designing production AI services, optimizing latency and throughput, managing caching, batching and streaming, and maintaining monitoring, logging, alerting, and incident response systems. The role requires reliable APIs, distributed-systems debugging, and scalable integration with LLMs, embeddings, and multimodal models.

Build integrations that enable AI agents to interact with first-party and third-party applications. Develop structured agent actions, information retrieval interfaces, cross-application workflows, reusable SDKs, and reliable asynchronous APIs. Manage authentication, authorization, permissions, and integration limitations while collaborating with Android engineers on system-level application access.

Develop and modify Android system services, privileged APIs, and OS-level AI integrations. Build interfaces for AI agents to interact with Android functionality while managing permissions, IPC, application lifecycles, background execution, performance, and resource consumption. Collaborate with agent engineers and debug Android Framework or AOSP components. Preferred experience includes custom ROMs, AOSP contributions, C++, System UI, background services, and power management.

Design AI-native interaction patterns and proactive experiences for everyday phone use. The role explores voice, touch, conversational, contextual, and multimodal interfaces; creates workflows across applications; makes agent actions transparent and controllable; and prototypes and validates new interaction models. The designer will collaborate closely with product and engineering teams and apply strong usability, product thinking, visual communication, and mobile interaction design skills.

Define the hardware platform strategy and roadmap for an AI-native smartphone. Evaluate mobile SoCs, NPUs, components, power, thermal performance, connectivity, and memory capabilities. Translate product and AI requirements into hardware specifications, assess vendor and ODM proposals, establish validation criteria, and determine whether commercial platforms or custom hardware are needed for current and future on-device AI workloads.

Build agent workflows, orchestration, tool integrations, context retrieval, memory, multi-step execution, and long-running stateful processes. Improve reliability through evaluations and regression testing, integrate local and cloud model providers, and support model routing and inference optimization. The role requires backend or AI application engineering expertise, strong API and distributed systems knowledge, and proficiency in Python, Go, or TypeScript.

Lead Android platform architecture and AOSP-based ROM development for an AI-native phone. Define OS-level AI integration, system services, privileged APIs, permissions, security architecture, and platform extensions. Partner with hardware vendors and ODMs on device integration, evaluate technical trade-offs, and establish Android platform engineering standards. The role requires deep Android internals expertise, ROM development experience, and strong technical leadership.

Integrate AOSP or custom Android ROMs with smartphone hardware, including BSPs, vendor HALs, firmware, drivers, sensors, cameras, audio, modems, Wi-Fi, and Bluetooth. Support device bring-up and boot processes, troubleshoot hardware and firmware compatibility, collaborate with ODMs, OEMs, and chipset vendors, and optimize power consumption and hardware performance.

Evaluate, deploy, and optimize machine learning models for on-device execution on Android phones. Benchmark models on mobile hardware, optimize latency, memory, and power consumption, and apply quantization, compression, and distillation. Integrate models with Android applications, system services, and AI agent runtimes. Build hybrid local/cloud model routing and determine which workflows should run locally versus through cloud inference.

Develop and modify Android Framework components, system services, privileged APIs, and secure AI-agent integrations. The role focuses on application lifecycle, permissions, background execution, first-party app integration, OS stability, performance, and collaboration with agent engineers. Candidates need strong Android development experience, Java or Kotlin proficiency, AOSP knowledge, and familiarity with Binder IPC, permissions, and complex Android debugging. Custom ROM, C++, Linux, Android security, power management, and system-level shipping experience are preferred.
