[Platform Engineering Hiring] Voice AI "Aibry" Lead Platform Engineer WantedTranslated from Japanese

▼Job Description This position is responsible for designing and building the system infrastructure that supports AI, LLM, real-time communication, and other technologies, driving the growth and scalability of multiple products from a technical perspective. You will lead the overall business growth through architectural design and infrastructure development. # Background Due to business expansion, the expectations and complexity required of our products are rapidly increasing. We are facing various challenges, including the new construction of company-wide infrastructure functions, responding to diverse customer needs, and undertaking new technological challenges with future growth in mind. A robust and flexible system infrastructure is essential to establish business growth and competitive advantage. Therefore, we are seeking a Platform Engineer who can take charge of the overall system architecture and demonstrate technical leadership. # Why Platform Engineering? While IVRy will continue to evolve its product that solves customer tasks through voice interaction, we are also planning to launch multiple new products that utilize unstructured "business communication data." To accelerate product development quickly and safely in the future, many technical challenges related to platform engineering will arise, spanning areas such as development environment scalability, product security, LLM Ops, and data engineering. Examples of current challenges include: - How should common modules (authentication, payment, etc.) be designed across multiple products? - How can we ensure that developers and staff handle sensitive data (personal data) securely? - What kind of development environment allows for a rapid product development cycle when generative AI is assumed as a prerequisite? We are looking for a leader who can not only address these challenges but also proactively identify major technical challenges that may arise in the future of the business, even those we haven't foreseen yet, and pave the way forward through platform development. # Main Responsibilities You will be broadly responsible for discovering technical challenges, overall system infrastructure design and construction, and technical leadership. ## Responsibilities - Planning, design, development, and operation of common service infrastructure - Technical decision-making and leadership ## Examples of Challenges to Solve ## New Construction of Infrastructure Systems - Authentication Infrastructure: Realization of Single Sign-On (SSO) and integrated identity management - Batch Infrastructure: Construction of a common infrastructure for executing routine and asynchronous processing - Logging Infrastructure: Construction of a common infrastructure for log collection, analysis, and monitoring across products ## Support for Multi-Product Deployment - Establishment of common infrastructure for rapid and efficient development and operation of multiple products - Design of a reliable architecture that can scale with the growth of each product ## Resolution of Technical Debt and Promotion of Modernization - Solving challenges related to the scalability and maintainability of existing systems - Introduction and promotion of modern technical practices ▼Required Skills/Experience - 3+ years of practical experience in designing, building, and operating common service infrastructure - Practical experience in development and operation using cloud platforms (especially AWS) ▼Preferred Skills/Experience - Experience in introducing microservice architecture and service segmentation - Experience in designing and building CI/CD pipelines - Experience demonstrating technical leadership, such as CTO or head of a technology department - Experience in designing and implementing authentication and authorization systems - Experience in designing and building batch processing systems - Experience in building and operating logging and monitoring systems - Experience in developing and operating systems related to telephone communication, such as SIP ▼Ideal Candidate Profile - Proactive in identifying issues and driving solutions - Able to look beyond their immediate role and exert influence across organizational boundaries - Eager to learn and adopt new technologies - Able to systematically explain the results of technical verification, etc. - Possesses leadership qualities to propose and drive the ideal direction for services and technologies ▼Attractions of the Job In many companies, infrastructure teams are separated from development teams, creating a distance from products, which makes it difficult for technical improvements to directly contribute to business growth. Alternatively, even when system infrastructure is built, it may only be used as an extension of existing systems, failing to solve fundamental problems. However, IVRy is a SaaS company where AI technology is at the core of its business. Since products cannot exist without AI technology, platform engineering that connects AI technology, products, customers, and developers directly impacts the customer's value experience. Therefore, the system infrastructure functions as the core of the product and supports business growth. Supporting "products where technical infrastructure is the protagonist" is the major attraction of working as a Platform Engineer at IVRy. ▼Development Environment We expect you to lead technology selection for new development, but here are the technologies currently in wide use: - Languages: Ruby, Python, TypeScript - Infrastructure: AWS (main), Google Cloud, Azure (partial use) - CI/CD: GitHub Actions - Monitoring: Datadog, Sentry - Tools: GitHub, Slack, Notion - AI: Cursor, Devin - DWH: Databricks ▼Employment Type Full-time employee (No fixed term) ▼Probationary Period 3 months (No change in salary or benefits during this period) ▼Salary Annual salary: ¥12,000,000 - ¥20,000,000 ▼Minimum Annual Salary (in 10,000 JPY) 1200 ▼Maximum Annual Salary (in 10,000 JPY) 2000 ▼Work Location Head Office Sumitomo Fudosan Tokyo Mita Garden Tower 10F, 3-5-19 Mita, Minato-ku, Tokyo 108-0073 Osaka Office Resort Trust Midosuji Building 18F, 4-14-3 Nishi-Tenma, Kita-ku, Osaka 530-0047 ▼Working Hours Flextime system Standard working hours: 8 hours per day (Core time: 10:00 AM - 3:00 PM) ▼Break Time 60 minutes ▼Overtime Work Available ▼Holidays, Paid Leave, Special Leave - Complete two-day weekend (Saturday and Sunday) - National holidays - Paid leave - Annual paid leave (granted based on start date of employment, up to 17 days) - Childcare leave - Bereavement leave ▼Benefits - Remote/Hybrid work - Unlimited free drinks in the office - Book purchase support - Welcome lunch within 3 months of joining - Monthly office open day (social gathering) - Unlimited access to bouldering - Unlimited music listening ▼Insurance Enrollment - Health Insurance - Employees' Pension Insurance - Workers' Accident Compensation Insurance - Employment Insurance ▼Measures to Prevent Passive Smoking at the Workplace No smoking on premises ▼Interview/Selection Process 1.
