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

The company is an HRTech company that develops and provides multiple services for various stakeholders in the recruitment field, such as hiring companies, recruitment agencies, and job seekers. Through the provision of recruitment management systems, reference check tools, and recruitment agency systems, the company aims to realize the optimal matching between companies and talent.

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

【Overview】

The company is an HR Tech firm that develops and provides multiple services targeting various stakeholders in the recruitment sector to achieve optimal matching between companies and talent.

Currently, its main product is an Applicant Tracking System (ATS) designed to accelerate digital talent recruitment. Around this core, the company operates a multi-product strategy that includes an AI-driven recruitment support service, an agency management system, and a job media platform specialized for startups.

The flagship ATS has been adopted by over 2,000 companies, ranging from IT ventures to enterprises listed on the Prime Market of the Tokyo Stock Exchange.

While the company has historically grown as an ATS provider, it is now aggressively pursuing a multi-product strategy. By combining organic growth in existing businesses with new business launches and strategic M&A, the organization aims to solve recruitment challenges from multiple angles and establish itself as a comprehensive recruitment platform.

【Recruitment Background】

The company has been expanding its multi-product ecosystem within the recruitment sector. Leveraging the technical foundation, recruitment domain expertise, and customer networks built through its previous growth, the organization is now driving the launch of an entirely new business aimed at solving fresh challenges in the recruitment market.

In this new venture, you will lead 0-to-1 product development while maintaining technical alignment with the existing HERP product suite and ensuring scalability for the future multi-product strategy.

To achieve this, the company is seeking a lead engineer who can spearhead the technical side of the new business launch—from initial architectural design and the establishment of the development structure to the creation of a technical foundation that supports business growth.

By joining at the early phase, you will have significant discretion over technology selection, architecture, and the formation of the development culture, allowing you to greatly expand your career alongside the growth of the product.

As an enterprise-grade product, the technical difficulty is extremely high—involving advanced security requirements, large-scale data processing, integration with existing systems, and flexible customization—which in turn provides significant fulfillment and opportunities for growth.

Working directly under the CEO, this is a rare position where you can draft technical strategies from a management perspective and commit directly to the success or failure of the business.

【Challenges Currently Being Addressed】

In launching this new business, the company is tackling the following technical challenges:

・Balancing Business Hypothesis Verification with Technical Sustainability: Achieving design that withstands future scaling while moving quickly toward PMF.

・Designing Integration with Existing Products: Providing unique value for the new business while leveraging existing assets such as HERP Hire.

・Starting Development with a Small Team: Selecting technologies and building a development structure to produce maximum output with limited resources.

・Addressing Both B2B and B2C Needs: Designing a flexible architecture that provides value to multiple stakeholders in the recruitment market.

・Utilizing AI and Generative AI: Realizing new user experiences in the recruitment domain by leveraging the latest technologies.

・Because this is the launch phase of the business, technical decision-making directly impacts its success or failure. The company is seeking an individual who combines high technical proficiency with a deep understanding of business.

【Responsibilities】

As a member of the New Business Division and a technical leader in the 0-to-1 phase of product development, you will be responsible for the following duties:

■Lead Product Development

・Participating in appointments and technical discussions with enterprise clients.

・Designing technical integration and data consolidation with existing products (such as HERP Hire).

*Scope of changes in duties: Tasks as defined by the company.

【Position Highlights】

■0→1 Discretion and Responsibility

・You will have significant discretion over technology selection and architectural design for the product.

・As an initial member of the business, you can be deeply involved in determining the product's direction.

■Leveraging Assets of Existing Businesses
