The Mid-Level Safety Systems Engineer is responsible for supporting and partially leading the engineering, implementation, validation, and maintenance of Safety Instrumented Systems (SIS), Emergency Shutdown Systems (ESD), and Fire & Gas Systems (F&G). This role involves lifecycle safety engineering, functional safety compliance, system configuration, and testing in accordance with IEC 61511 / IEC 61508 standards.
Design and review Safety Requirement Specifications (SRS), interlock logic, and Cause & Effect (C&E) diagrams.
Configure and verify SIS logic on safety PLC platforms (e.g., Triconex, HIMA, ProSafe-RS, Siemens).
Lead or assist in Safety Lifecycle implementation in compliance with international standards.
Participate in and support SIL determination, verification, and validation based on HAZOP, LOPA, and risk matrices.
Work closely with functional safety consultants and internal teams for compliance with IEC 61511, ISA S84, and IEC 61508.
Ensure traceability and documentation throughout the safety lifecycle phases.
Plan and execute Factory Acceptance Tests (FAT) and Site Acceptance Tests (SAT) for SIS and F&G systems.
Lead loop checking, safety trip testing, and functional verification of SIFs during commissioning and startup.
Interface with control/DCS teams for system integration and signal integrity.
Support the implementation of proof testing, diagnostics, and preventive maintenance strategies for SIS.
Troubleshoot safety system issues in coordination with operations and maintenance teams.
Analyze failure reports and recommend corrective actions.
Prepare, maintain, and review documentation including test procedures, validation reports, and MOC (Management of Change) records.
Support safety audits and compliance inspections.
Ensure all safety-critical documentation is up to date and aligned with plant standards.
Strong understanding of safety system architectures (e.g., 1oo1, 1oo2, 2oo3).
Hands-on experience with safety PLCs (Triconex, HIMA, Siemens, etc.).
Knowledge of functional safety principles and risk assessment techniques (HAZOP, LOPA).
Proficiency in reading and preparing P&IDs, loop diagrams, wiring drawings, and logic diagrams.
Excellent communication, documentation, and cross-functional collaboration skills.
B.E. / B.Tech in Instrumentation, Electrical, Electronics, or related engineering discipline.
3–7 years of relevant experience in Safety Instrumented Systems, preferably in project and operational environments.
Knowledge of international standards: IEC 61511, IEC 61508, and ISA S84.
Functional Safety Certification (TÜV Rheinland, Exida) preferred or in progress.
Experience with control and safety system integration is an advantage.
