【Robotics Engineer】（Physical AI） JLPT N2 Flextime & Hybrid Work

★Robotics Engineer（Physical AI） | AI Development Platform Provider

• Business Level Japanese Required

◆ Flextime & Hybrid Work

◆ Start-up Company

◆ Annual salary: 6 million yen - 15 million yen

-------------【About the company】-------------

Adopting a "Data-Centric AI Development" approach, the company specializes in the collection and creation of "high-quality data," which directly dictates the accuracy and safety of AI models. While it is often said that data preparation accounts for 80% of the AI development process, the company addresses this challenge through its proprietary platform.

1. In-house Product: AI Data SaaS

The company operates a platform where crowdworkers from around the world participate in annotation (creation of training data) by utilizing a mechanism similar to "poi-katsu" (reward-earning) apps. By leveraging proprietary quality-control algorithms, the company achieves low-cost and rapid data collection.

2. Data Collection and Annotation Services

The company handles a wide range of projects, from "0 to 1" new development to large-scale operational tasks based on well-defined requirements. It addresses diverse orders in cutting-edge technical fields—such as Large Language Models (LLM), Retrieval-Augmented Generation (RAG), voice recognition, and multi-modal AI—through its flexible and advanced development capabilities.

3. Provision of High-Quality Data Sets

The company provides "rights-cleared" data sets that are essential for AI training, ensuring both quality and legal compliance for its clients.

■Strengths and Track Record

The company’s client base primarily consists of enterprise-level organizations. It supports numerous top players across various industries, notably including the provision of Japanese data for Meta’s Large Language Models (LLM). Rather than being just an AI tool provider, the company has garnered significant market attention as a key player that controls "data"—the very essence of AI.

-------------【 Job Description】-------------

■About the Company

The company is an agile startup founded specifically to eliminate the "data preparation bottleneck"—the primary hurdle most enterprises face during AI development.

The organization provides a cloud-based data collection and annotation platform designed to streamline and accelerate the preparation of the high-quality data essential for training and operating AI models. The flagship offerings include an AI data platform that centralizes data creation across internal teams and crowdsourced workforces, ready-to-use training datasets spanning diverse domains, and tailored contract solutions to accelerate AI model development. These services have already seen widespread adoption among major Japanese corporations and industry leaders.

Furthermore, by leveraging a proprietary smartphone app to mobilize global cloud workers, alongside a highly distributed multi-language, multi-regional data collection network, the company has established a robust infrastructure fully capable of supporting global-scale AI implementations.

■Recruitment Background

The company is aggressively accelerating its strategic investments in the Physical AI and robotics domains. Within this ecosystem, developing robust hardware capabilities to capture, control, and operationalize real-world data is becoming just as critical as evolving the core AI models themselves.

In this position, you will head the development of the physical machinery that powers next-generation Physical AI systems. Working in close loop with the AI and software engineering teams, your primary focus areas will include:

・Mechanical Design

・Prototyping & Iteration

・Sensor & Device Integration

・Enclosure/Chassis Design

・Hardware Validation

・Simulation

This is not a passive, outsourced contract-design role. You will be entering an environment where you are expected to fundamentally redefine "What does hardware need to look like in the era of advanced AI?"—giving you absolute autonomy to conceptualize, iterate, and build from 0 to 1.

■Responsibilities

・Mechanism and enclosure design using CAD

・Prototype development, assembly, and evaluation

・Hardware configuration planning, including sensors and cameras

・Design and improvement of robotics-related equipment

・Device development for AI data acquisition

・Coordination of specifications with software and AI teams

・Component selection, ordering, and vendor negotiations

・Design improvements with an eye toward mass production

・Hardware improvements from proof of concept (PoC) to actual operation

・Data expansion

■Position Highlights

・Enter at the ground floor of the "Physical AI" domain—widely recognized as the next frontier following generative AI—and play a foundational role in building this business segment from scratch.

・Collaborate closely with elite AI/ML engineers to build deeply integrated systems where software algorithms and physical machinery operate in perfect synergy.

・Move far beyond siloed CAD design. You will be fully involved in the entire lifecycle of the hardware, including rapid prototyping, physical assembly, iterative improvements, and real-world operations.

・Avoid the trap of perpetual Proof-of-Concepts (PoCs). Your engineering output will directly drive actual, field-deployed AI data ingestion workflows and advanced robotics applications.

・Because this is an early-stage initiative, you will wield immense decision-making authority over initial product specifications, component sourcing, vendor selection, and overarching hardware architecture.

-------------【 Requirements】-------------

■Required

・Experience in 3D CAD design using Fusion 360, SolidWorks, CATIA, Inventor, etc.

・Practical experience in mechanical design, enclosure design, and fixture design

・Experience managing the entire process from prototyping through assembly, evaluation, and improvement

・Design experience that takes into account 3D printing, machining, sheet metal fabrication, etc.

・Experience working with hardware configurations that include sensors, cameras, and electronic components

・Experience driving improvements by working directly with physical prototypes, rather than relying solely on desk-based design

・Experience collaborating with software and electrical engineers on development projects

■Preferred

・Experience developing robotics-related products

・Experience in robotics development using ROS/ROS2

・Experience developing sensing devices using cameras, LiDAR, IMUs, etc.

・Experience developing data acquisition devices for computer vision and AI

・Experience with prototyping using Arduino, Raspberry Pi, Jetson, etc.

・Experience with control and verification using Python/C++

・Experience in mass-production design, outsourcing manufacturing, and ODM/OEM management

・Experience in 0-to-1 development at startups or in new business ventures

・Strong interest and expertise in the fields of Physical AI, Robotics, and Edge AI
