Engineering Manager / Team Leader

Job Description:

The Engineering Manager / Team Leader is a hands-on engineering role for Solar C&I Projects in Vietnam, reporting directly to the Head of Engineering - C&I Asia. The position combines direct design and analytical work with day-to-day coordination of the Vietnam Engineering Team. The candidate is expected to independently produce AutoCAD designs, PVsyst simulations and export analyses, and take on engineering work whenever additional team capacity is required. Support for EPC-submitted technical document reviews and approvals is a secondary responsibility. Confirmation of the Team Leader designation will depend on probation performance in technical execution, delivery and team leadership.

1. Hands-on Engineering Design & Analysis

• Personally prepare and revise Solar PV layouts, single-line diagrams (SLDs) and supporting engineering drawings using AutoCAD for feasibility and project design.
• Develop and validate PVsyst energy-yield simulations, PV system sizing, production estimates and underlying technical assumptions.
• Perform load-profile and solar export analyses, including self-consumption, export-limit / zero-export and curtailment assessments where applicable.
• Prepare key design calculations and technical inputs covering DC/AC configuration, inverter selection, cable sizing, voltage drop and grid interconnection.
• Independently take on design packages, site surveys and technical studies to supplement team capacity during peak workloads or resource constraints.

2. Team Coordination, Leadership & Delivery

• Coordinate the Vietnam Engineering team's daily work, assign priorities and balance resources across multiple projects.
• Remain an active design contributor while taking accountability for team deliverables, engineering quality and agreed submission dates.
• Provide practical technical guidance, check critical team outputs and coach engineers to strengthen their design capability and ownership.
• Monitor workloads, progress and open issues; report resource needs and key decisions to the Head of Engineering and support team development activities.

3. EPC Technical Submissions & Coordination

• Support review and the internal approval process for EPC-submitted drawings, calculations, equipment datasheets, method statements and other technical documents in accordance with delegated authority.
• Coordinate technical clarifications with EPC contractors, Owner's Engineers (OE), Independent Engineers (IE) and internal project stakeholders as required.
• Check compliance with CE standards and project requirements, track technical comments and follow up on revisions and outstanding submissions.
• Identify design inconsistencies, material deviations and gaps in EPC technical scopes, escalating significant issues with practical recommendations.

4. Tendering, RFP & BD Technical Support

• Prepare and review tender technical scopes, RFP documents, design criteria and engineering specifications.
• Support Business Development (BD) with feasibility assessments, conceptual designs, energy estimates and technical assumptions.
• Evaluate EPC proposals, clarify technical deviations and provide recommendations balancing compliance, quality, cost and delivery.

5. Quality Control, Risk & Issue Resolution

• Perform quality checks on own designs and support review of team designs to ensure technical accuracy, constructability and compliance before submission.
• Personally support technical troubleshooting and resolution of engineering issues during design, construction, commissioning and early operation.
• Identify significant technical, schedule or contractual risks and recommend appropriate mitigation and corrective actions.

6. Technical Governance & HSSE Compliance

• Ensure designs and technical submissions comply with CE engineering standards, applicable Vietnamese requirements and HSSE principles.
• Manage technical deviations and design changes with proper justification, records and approvals under company procedures.
• Review and endorse routine technical submissions within delegated authority; escalate deviations or material exceptions for formal approval.

7. Stakeholder Management, Reporting & Escalation

• Represent Vietnam Engineering in technical discussions with BD, Project Management, Procurement, HSSE, EPCs and clients.
• Make timely decisions within assigned authority, escalating critical risks and issues with clear options and recommendations.
• Report proactively to the Head of Engineering - C&I Asia on engineering progress, priorities, resources and key decisions.

8. Equipment Evaluation, Handover & Documentation

• Evaluate and benchmark key Solar PV equipment, including modules, inverters and balance-of-system components.
• Provide technical comparisons and recommendations to support equipment selection and procurement decisions.
• Oversee engineering handover documentation, including design records, as-built drawings and technical inputs for Construction and O&M.

9. M&A & Regional Technical Support

• Support technical due diligence for M&A and project acquisitions, identifying technical gaps, risks and mitigation measures.
• Provide engineering support to other countries or regional initiatives when assigned, while maintaining Vietnam delivery priorities.

Qualifications

• Based in Vietnam or willing to relocate, with eligibility to work in Vietnam and willingness to travel as required.
• Bachelor's degree in Electrical Engineering, Power Engineering or a related field.
• Minimum 5 years of relevant Solar PV engineering experience, preferably including hands-on design and delivery of C&I projects.
• Minimum 2 years of experience in engineering team management or technical team leadership.
• Proven ability to independently prepare AutoCAD drawings, PVsyst simulations, PV sizing and energy/export analyses for actual projects.
• Experience coordinating or guiding engineers, prioritizing workload and taking responsibility for technical deliverables.
• Hands-on EPC project experience across design, tendering, construction and commissioning, including review of technical submissions.
• Familiarity with Vietnamese engineering regulations, EVN/grid interconnection requirements and LV/MV electrical systems.
• Good working command of Vietnamese and English, both written and spoken, for local and regional coordination.
• Experience with BESS projects (sizing, integration or technical review) is an advantage, not a requirement.

Skills

• Strong hands-on solar design capability, with advanced practical proficiency in AutoCAD and PVsyst.
• Able to perform and explain energy-yield, load-profile, self-consumption and export-limit / zero-export analyses.
• Good technical judgment, problem-solving ability and willingness to personally execute design work alongside the team.
• Able to lead and coordinate people and priorities across multiple projects while maintaining quality and delivery commitments.
• Effective communication with EPCs, BD and internal stakeholders, including clear reporting and escalation of technical risks.
• Proficient in Microsoft Office; familiarity with SketchUp is an advantage. Leadership and coaching skills are highly preferred.
