Job description

• Implement the requirements of the EHS management system documents across the facility, ensuring process safety practices are embedded in daily operations.
• Establish and continuously improve technical standards and internal specifications for process safety assessment, aligning with international best practice (CCPS, IEC 61511, ISO 45001) and local regulatory expectations.
• Maintain full proficiency in HAZOP and other analytical tools and standards (LOPA, What-If, Bow-Tie, SIL/LOPA studies); develop and enhance the company's process safety database, assessment models, and evaluation criteria over time.

Hazard Identification & Risk Assessment

• Take charge of HAZOP assessments for plant infrastructure and utilities, and propose appropriate, practical control measures.
• Conduct safety assessments for plant production projects, skilfully applying HAZOP, preliminary risk assessment, and other recognised tools; perform evaluations in line with established criteria.
• Identify process and operational hazards and translate findings into clear operational and engineering control requirements that operations teams can act on.
• Provide technical guidance to the review team during assessments, ensuring analyses are conducted rigorously and consistently in accordance with established standards and methodologies.

Operational Discipline

• Review process safety operating procedures and oversee implementation to ensure that safety measures specified in process safety assessment reports are fully carried through to the plant floor.
• Participate actively in EHS Management of Change (MOC), identifying and evaluating EHS risks arising from proposed changes, determining appropriate risk-mitigation measures, and following up on their implementation to closure.
• Participate in Pre-Startup Safety Review (PSSR) inspections, supervising and confirming that safety measures identified during process safety assessments are in place before startup.

Chemical & Hazard Information Management

• Take ownership of chemical management processes, including the collection, organisation, maintenance, and issuance of Safety Data Sheets (SDS/MSDS), safety labels, and related hazard communication documentation.
• Lead the investigation and root-cause analysis of process safety incidents and latent hazards (near misses, process deviations), and track corrective and preventive actions through to verified completion.
• Undertake other duties as assigned by management in support of the site's process safety and EHS objectives.

Requirements:

• Degree in Chemical Engineering, Process Safety, or a related engineering discipline.
• Demonstrated hands-on experience leading or facilitating HAZOP studies and other structured hazard analysis techniques within a chemical or pharmaceutical manufacturing environment.
• Working knowledge of Singapore's WSH regulatory framework, including MHI notification and Safety Case requirements where applicable.
• Familiarity with MOC and PSSR processes within a GMP-regulated manufacturing setting.
• Strong analytical rigor combined with the practical judgment to translate hazard findings into workable, risk-proportionate controls.
• Clear communication skills — able to guide cross-functional review teams and influence operations, engineering, and quality stakeholders alike.
• A collaborative, standards-driven mindset with genuine ownership over the safety of the people and processes you support.
• Fluent in English (written and spoken); proficiency in Chinese is a plus
