Job description

Senior Manufacturing Engineer – Digital Twin Programme

Location: Onsite, Derbyshire

Contract: Inside IR35 contract available

Eligibility: Only applicants with active SC clearance or who are eligible to obtain SC clearance can be considered. Unfortunately, visa sponsorship is not available.

Overview

A leading Defence organisation is embarking on a major two-year investment to transform its Digital Twin and smart manufacturing capability. As part of this programme, they are seeking a highly skilled Senior Simulation Engineer with experience in Siemens environment, Tecnomatix Plant Simulation and discrete event modelling. Very exciting project and excellent time to join them - you will be one of the very first people they bring into their team! You will play a pivotal role in shaping how next‑generation factories are designed, configured and optimised-translating real-world constraints into high‑fidelity digital models that influence strategic decision‑making across the business.

What You Will Do

• Develop and enhance Digital Twin simulation models for manufacturing environments.
• Use Tecnomatix Plant Simulation to build discrete event simulations, creating virtual representations of production and logistics systems.
• Analyse system performance models, identify bottlenecks and inefficiencies, and propose data-driven improvements.
• Work closely with operational, engineering and programme stakeholders to translate real‑world scenarios into accurate simulation logic.
• Validate models against live manufacturing data to ensure digital outputs reflect actual shop‑floor conditions.

What You Need to Succeed

• Proven experience building manufacturing simulations at factory and/or cell level.
• Hands‑on expertise with Siemens Plant Simulation and/or related Tecnomatix tools.
• Strong understanding of discrete event simulation principles for industrial environments.
• Ability to design, structure and debug plant simulation models, including frames, inheritance, methods and experiment management.
• Experience validating simulation outcomes with real manufacturing metrics and operational data.
• Confidence in working with production inputs such as process times, WIP constraints, line balancing, buffers and throughput assumptions.
• Clear communication skills, able to explain model logic, behaviours and insights to both technical and non-technical audiences.

Nice to Have

• Prior experience with Digital Twin projects within a manufacturing setting.
• Previous Defence sector experience or active SC clearance.
