Job Description:

Chief Engineer / Head of Architecture & Engineering — Network Control Japan

• Network Control Japan | Hitachi Energy
• Location: Tokyo, Japan
• Employment type: Full-time, regular
• Function: Engineering / Architecture / Project Delivery
• Program: JIEMS — Japan Integrated Energy Management System / Next-Generation Nationwide Load Dispatching System
• Reports to: Program Director — administrative / HR reporting
• Day-to-day reporting: Project Director — delivery execution and priorities

1. Role Purpose

The Chief Engineer / Head of Architecture & Engineering — Network Control Japan will provide senior technical leadership for Hitachi Energy Network Control’s largest Japan program: the delivery of a next-generation, nationwide energy management and load dispatching capability for Japan’s transmission and distribution sector.

This role is accountable for the technical coherence, architecture integrity, engineering governance, and customer-facing technical leadership of the JIEMS solution. The position will serve as the senior Japan-based engineering authority across Energy Management Systems, Market Management Systems, SCADA/EMS, utility integration, operational technology, cybersecurity, testing, commissioning and long-term operability.

The successful candidate will operate at the intersection of:

• •Japanese utility customer expectations
• •Hitachi Energy global product and engineering teams
• •Hitachi Japan / Social Infrastructure stakeholders
• •Program and project delivery leadership
• •Local Network Control Japan succession and capability-building objectives

This is a hands-on leadership role for a senior engineer who can both shape architecture and drive execution discipline on a mission-critical national infrastructure program.

2. Strategic Context

JIEMS is a nationally significant energy infrastructure program. It brings together Hitachi’s domestic experience in Japan’s mission-critical power systems with Hitachi Energy’s global Network Manager software portfolio, including SCADA, EMS and MMS capabilities.

The program requires a leader who can translate between:

• •Japanese power-system operating requirements
• •Global product architecture and release roadmaps
• •Safety, reliability, cybersecurity and regulatory obligations
• •System integration realities across IT and OT environments
• •Executive delivery pressure on a complex, multi-year program

The role is also part of the Network Control Japan operations succession plan . A core expectation is to help build a durable Japan-based technical leadership bench, reducing dependency on global/hub escalation and strengthening local ownership of architecture, engineering standards, customer interface and operational continuity.

3. Key Accountabilities

A. Architecture Leadership

The role will own and maintain the end-to-end Master Architecture for the JIEMS solution.

Responsibilities include:

• •Define, maintain and govern the complete solution architecture across EMS, MMS, SCADA, system integration, data flows, interfaces, infrastructure, cybersecurity and operational processes.
• •Ensure architecture decisions remain aligned with approved delivery strategies, product roadmaps, customer requirements, engineering standards and long-term maintainability.
• •Lead architecture reviews and design authority forums across Hitachi Energy global teams, Hitachi Japan teams, product development, project delivery and customer stakeholders.
• •Resolve cross-domain technical conflicts between EMS, MMS, SCADA, IT infrastructure, OT integration, market interfaces, data engineering and commissioning workstreams.
• •Ensure architecture documentation is current, traceable, decision-ready and usable by engineering, project, customer and operations teams.
• •Provide clear technical options, recommendations and risk trade-offs to the Project Director and Program Director.

B. Engineering Governance and Delivery Assurance

The role will act as the senior engineering authority for technical delivery quality.

Responsibilities include:

• •Establish engineering governance for design, build, integration, test, release, commissioning and transition-to-operations.
• •Drive consistency across requirements management, design baselines, interface control documents, technical assumptions, change control and acceptance criteria.
• •Identify, qualify, quantify and manage technical risks, dependencies and engineering constraints.
• •Ensure product releases, customizations, integration milestones and testing activities are technically ready and aligned to committed program milestones.
• •Review and challenge technical plans for feasibility, sequencing, resource readiness and implementation risk.
• •Provide technical input into project status reports, executive updates, customer reviews, risk reviews and schedule recovery plans.
• •Ensure lessons learned are captured and converted into repeatable local engineering practices.

C. EMS / MMS / SCADA / Utility Integration Leadership

The role will provide expert oversight across the core Network Control technology stack.

Responsibilities include:

• •Lead technical decision-making across EMS, MMS, SCADA and related grid / market control functions.
• •Provide direction on load dispatching, supply-demand balancing, market integration, network modeling, state estimation, contingency analysis, generation scheduling, LFC, SCUC, SCED and related power-system applications.
• •Ensure the solution supports real-time control, predictive optimization, market operations, operator workflows and secure data exchange.
• •Oversee integration with external utility systems, market systems, customer systems, data platforms, operational interfaces and third-party software.
• •Ensure interoperability approaches are robust, secure, documented and testable.
• •Guide teams through complex interface issues involving data models, telemetry, communication protocols, database integration, visualization, alarms, events, historian data, reporting and operational workflows.

D. Customer-Facing Technical Leadership

The role will be a senior technical counterpart to the customer and end-client organizations.

Responsibilities include:

• •Serve as a trusted senior technical interface for customer architecture, engineering and integration topics.
• •Lead technical workshops, architecture reviews, dependency reviews and issue-resolution sessions with Japanese customer stakeholders.
• •Translate complex engineering issues into clear business, schedule and operational implications.
• •Maintain strong relationships with customer-side technical leads, end users, Hitachi Japan stakeholders and Hitachi Energy global experts.
• •Ensure Japanese-language technical discussions are handled with credibility, precision and cultural fluency.
• •Support the Project Director and Program Director in executive-level customer communications where technical clarity is essential.
• •Protect the quality and integrity of Hitachi Energy’s technical position while remaining pragmatic and collaborative.

E. Testing, Acceptance, Commissioning and Transition

The role will ensure that the delivered system is testable, accepted and operable.

Responsibilities include:

• •Provide senior technical leadership for system integration testing, Factory Acceptance Testing, Site Acceptance Testing, commissioning and operational readiness.
• •Ensure test scope, test data, environments, scripts, defect handling and acceptance criteria are aligned to architecture and customer requirements.
• •Drive resolution of complex technical defects and integration blockers.
• •Ensure architecture and engineering decisions support high availability, resiliency, fallback operations, disaster recovery and maintainability.
• •Support training, knowledge transfer and transition-to-servic
