[Sony Group Origin] IoT/DX Platform Development Supporting Social Infrastructure | Full-Cycle Engineer with High Discretion from API Design to Refactoring ▼Job Description With the vision of "Innovation is always by your side," we are developing an "MVNE (MVNO Support) business" and an "IoT/DX Platform business" that accelerate DX in all industries through communication. 【Specific Customer Issues Solved Through Our Products】 The systems we provide are the lifeline for our clients, the MVNO operators. Furthermore, the communication facilitated by our IoT/DX platform is integrated into the vital arteries of society, such as logistics, payment, and infrastructure monitoring, where downtime is unacceptable. Even a momentary system interruption or delay can lead to significant economic losses. Therefore, by maximizing the stability and fault tolerance of our infrastructure, we support an environment where clients can expand their businesses with peace of mind. 【Job Responsibilities】 You will be responsible for the overall development and operation (requirements definition, design, implementation, testing, release) of our proprietary product, the "IoT/DX Platform 'MEEQ'," which accelerates corporate IoT/DX. 【Specific Tasks】 ◆ Development of APIs for Visualization and Control of Large Volumes of Devices: Design and develop robust and high-speed Web APIs (Public APIs) and a Web console that allow clients to centrally manage the "activation, suspension, and cancellation" of tens of thousands to millions of SIMs (e.g., smart meters, in-vehicle devices) programmatically from their own systems. ◆ Development of Traffic Data Aggregation and Analysis Platform: Develop backend functions to aggregate and visualize the vast amount of communication data sent in real-time from a large number of devices without delay, enabling customers to make cost optimization decisions. ◆ Modern Architecture Overhaul: To maintain the speed of feature expansion, refactor the existing system into a modular monolith structure, etc., and promote the organization of domain responsibilities and redesign. 【Significance of Joining at This Phase】 Due to rapid business growth, the communication traffic and data volume we handle continue to increase. The biggest advantage of joining now is the opportunity to "leverage the existing product foundation while leading new feature development and proactively addressing design improvements and technical debt from the outset." This is not simply ticket-based development (passive development) left to a Product Manager; you will be in a position to create "the very value of the product" through the full cycle from requirements definition to technology selection and implementation, with significant discretion and opportunities. 【Expected Role and Technical Challenges】 We expect you to not only function as an implementer driving feature development but also, in the long term, to act as a lead engineer involved in the design and improvement of your area of responsibility. ◆ The Appeal of Domain Abstraction: You will hone high-level design skills by abstracting the extremely complex procedures of communication line contracts and SIM management into simple APIs and intuitive web interfaces. ◆ Full-Stack Growth Environment: By being involved across the stack from front-end to back-end and API design, this is an environment that will satisfy the technical curiosity of engineers who "want to further improve their skills as implementers," "want to acquire next-level technical capabilities," or "want to go beyond just building to consider better ways of building." 【Technical Challenges Our Development Organization is Currently Tackling!】 ◆ Performance Improvement Across APIs/DBs: Design improvements that enhance reusability by organizing and standardizing implementations and design policies that vary across services, and separating the responsibilities of common modules. ◆ Overhauling Development Processes Using AI: Building a system that maximizes development productivity by actively incorporating generative AI tools into daily tasks, code reviews, and test automation. ▼Required Skills/Experience 【1】Possess experience in either of the following, and meet all of the requirements in 【2】: 【1】 ・Practical development experience in web applications (backend) using one of Java, Kotlin, or Python (approximately 3+ years). ・Practical development experience in front-end using modern frameworks such as Vue.js or React. 【2】 ・Experience in developing and operating web services using AWS or similar cloud platforms. ・Ability to communicate smoothly with various internal stakeholders, such as sales and planning, to advance work. ▼Preferred Skills/Experience ・Practical development experience in both backend (Java/Kotlin/Python) and frontend (Vue.js/React). ・Experience in replacing legacy environments like jQuery with modern frontend frameworks. ・Experience in developing and improving proprietary products in SaaS or platform businesses. ・Experience in improving development efficiency using generative AI (LLM, etc.) in practical applications or incorporating it into products. ・Experience in building and operating CI/CD environments using AWS CodePipeline or similar tools. ▼Ideal Candidate Profile ・Individuals who are committed to creating value for "solving customer issues" with the business side, not just writing code. ・Individuals who can proactively learn new technologies such as frontend modernization and AI utilization and apply them to products. ・Individuals who can communicate smoothly with various internal stakeholders, including sales and planning, beyond the engineering team, and proceed with development through flexible adjustments and collaboration. ▼Job Highlights ◆ The Fascination of Simplifying "Complex Communications" and Accelerating Corporate DX: You can experience the ingenuity of product design that abstracts the extremely complex mechanisms of communication lines and their management into easy-to-understand UIs and smart APIs. ◆ High Discretion to Be Involved Holistically from Requirements Definition and Technology Selection, Working Alongside the Business Side: Instead of simply processing tickets (passive development), you can lead and drive new feature development and specification adjustments through direct collaboration with other departments such as sales and planning. ◆ Latest Technology Trends such as Migrating from jQuery (Vue.js Refresh) and AI Utilization Leveraging IoT Data: You can challenge yourself with proactive development, such as frontend modernization replacements and prototyping new features using vast accumulated IoT data combined with generative AI. ▼Development Environment Development Languages: Java (Spring), Kotlin, Python, JavaScript (JQuery, Vue.js) Databases: RDB, MySQL Infrastructure: AWS, On-premises Source Code Management: GitHub CI/CD: AWS CodePipeline IaC: CloudFormation, AWS CDK Monitoring: CloudWatch, New Relic, Pagerduty ▼Employment Type Full-time employee (No fixed term) ▼Probationary Period 3-month probationary period.
