Job overview

This role contributes directly to DEISO’s position as an execution company focused on technically defensible work, independent expert review, and execution-oriented readiness support. It is not generic consulting, general advisory work, or certification activity. It centres on structured technical audit, pre-submission assessment, methodological consistency review, and strengthening execution quality before external use, disclosure, or verification-related processes.

The selected professional will assess whether technical sustainability outputs are sufficiently organized, internally coherent, reviewable, and ready for responsible downstream use — identifying execution risks, technical weaknesses, data limitations, methodological inconsistencies, and readiness gaps that affect quality.

Through that work, the role supports how DEISO executes complex sustainability projects, improves technical strength, and reinforces the professional discipline required for high-quality execution and review under enterprise conditions.

Key responsibilities

• Perform structured technical audit and expert review of sustainability outputs to strengthen execution quality, consistency, and readiness.
• Identify methodological issues, data gaps, internal inconsistencies, and technical weaknesses affecting pre-submission readiness or downstream confidence.
• Assess whether completed work is organized and documented in a way that supports reviewability, traceability, and professional execution standards.
• Contribute to pre-submission readiness reviews that improve the quality of technical outputs before external assessment or client-facing use.
• Prepare clear findings, structured audit observations, and expert recommendations that improve execution strength and reduce avoidable technical risk.
• Support the development of review logic and technical audit approaches aligned with DEISO’s execution-led model.
• Work closely with technical experts to strengthen the pathway from completed analysis to review-ready, decision-ready outputs.

Candidate requirements

• A strong professional background in technical audit, independent review, compliance readiness support, sustainability quality assurance, or a closely related field.
• Demonstrated ability to assess technical outputs critically and improve their suitability for structured execution and professional review.
• Strong judgment in identifying methodological inconsistencies, data integrity concerns, technical weaknesses, and execution-related risks.
• Ability to work within an expert-led environment where high-quality execution, structured review, and technical discipline are central.
• Business-level Japanese language capability is required across written, oral, and spoken communication.
• High standard of professional writing, analytical clarity, and evidence-based communication.
• Ability to operate with precision, maturity, and discretion in a company serving global clients through technical execution and expert-led review.

Preferred skills

• Experience in technical review, readiness support, pre-submission assessment, quality control, or structured expert evaluation of sustainability outputs.
• Ability to convert technical observations into clear, professionally usable findings that improve execution confidence.
• Strong understanding of how technical documentation, review logic, and methodological discipline shape enterprise-level execution.
• Comfort working across expert, technical, and client-facing contexts while preserving neutrality, rigour, and clarity.
• Experience in environments where audit insight improves technical strength, risk visibility, and execution readiness.

Why this role matters at DEISO

The position supports DEISO’s identity as an execution company that values audit discipline, technical accountability, methodological clarity, and review-ready output. It protects quality while strengthening the trustworthiness and professional readiness of sustainability work.
