## Description

Location: Singapore, Singapore Thales is a global technology leader trusted by governments, institutions, and enterprises to tackle their most demanding challenges. From quantum applications and artificial intelligence to cybersecurity and 6G innovation, our solutions empower critical decisions rooted in human intelligence. Operating at the forefront of aerospace and space, cybersecurity and digital identity, we’re driven by a mission to build a future we can all trust. In Singapore, Thales has been a trusted partner since 1973, originally focused on aerospace activities in the Asia-Pacific region. With 2,000 employees across three local sites, we deliver cutting-edge solutions across aerospace (including air traffic management), defence and security, and digital identity and cybersecurity sectors. Together, we’re shaping the future by enabling customers to make pivotal decisions that safeguard communities and power progress. Responsibilities : Technical leadership · Lead, plan and coordinate the systems engineering activities for the NexGen Digital Twin scope delivered from Singapore, including the Systems Engineering Management Plan (SEMP) contribution, work breakdown, estimates and technical milestones. · Lead and mentor a team of systems engineers: assign work, review their artefacts, set quality standards for requirements and architecture. · Act as the technical authority for system-level decisions within the delegated scope, escalating to the Project Design Authority where decisions affect the overall solution baseline, safety case or contract. · Prepare for, present at and close actions from formal technical reviews, such as SRR, PDR, CDR, TRR and acceptance readiness reviews, with entry and exit criteria that are evidence-based. Requirements and architecture · Own the elicitation, analysis, specification and management of system and subsystem requirements across the lifecycle, following ISO/IEC/IEEE 29148 and the INCOSE Guide to Writing Requirements (GtWR) : every requirement necessary, unambiguous, singular, feasible and verifiable , and every requirement set complete, consistent and able to be validated. · Interpret customer tender and contract requirements, digital twin operational concepts and use cases into a coherent system requirements baseline, and manage compliance positions and clarifications with the customer. · Maintain bidirectional traceability : stakeholder need → system requirement → architectural element → implementation → verification evidence. This is the artefact an auditor and the customer will ask for, and it must exist as a living structure, not a retrofit. · Operate the systems engineering process within an ISO/IEC/IEEE 15288 lifecycle frame (as codified in the INCOSE Systems Engineering Handbook, 5th edition ): stakeholder needs and requirements definition, system requirements definition, architecture definition, integration, verification, transition, validation and operation. · Run a digital / model-based engineering toolchain rather than documents-in-a-folder: requirements and models held in managed repositories with change control, baselines and query-able trace links (e.g. Capella/Arcadia or SysML-based MBSE, with DOORS, Polarion, Jama Connect or the toolchain the programme standardises on). · Translate non-functional requirements (latency, availability, recoverability, capacity, degraded-mode operation, cybersecurity posture) into concrete, testable engineering targets, and confirm through analysis and test that they are met. Interfaces and integration · Own the definition and control of external and internal interfaces through Interface Control Documents (ICDs) and interface requirements, including ATM and non-ATM data exchanges such as ASTERIX surveillance data, ATS inter-facility data communication ( AIDC/OLDI ), aeronautical and meteorological information, and digital data exchanges (e.g., JSON, ReST, Streaming Data). · Lead the system integration strategy and sequence, coordinate
