ATC Senior Design Engineer

Siemens Mobility is an outstanding place to have a career in an innovative environment. Siemens Mobility Rail Infrastructure business supplies the global markets of rail and road-bound transport with innovative products and solutions for Rail Automation, Rail Electrification, and intermodal mobility, apps, and backend systems.

What are my job responsibilities?

We are seeking a highly skilled and detail-oriented ATC Senior Design Engineer to support the design, development, and deployment of CBTC GoA 4 signalling solutions for urban rail systems. The ideal candidate will bring deep technical expertise in ATC system design, with specific experience in rolling stock interfacing, system simulation, and performance-critical subsystems. You will play a key role throughout the project lifecycle, ensuring optimal integration and performance of automatic train operation.

• Lead and contribute to the design of CBTC GoA 4 ATC systems, including concept development, detailed design, integration, and validation.
• Create and review CBTC scheme plans, ensuring compliance with signalling principles, operational requirements, and project constraints.
• Conduct headway simulations and performance assessments to validate system throughput and dwell time criteria.
• Define, document, and verify rolling stock interfaces, both hardware (e.g., onboard ATC equipment, cabling, I/O) and functional (e.g., control messages, passenger announcements).

• Integrate ATC systems with critical onboard functions including:

• Traction and brake performance profiles

• Passenger information and announcement systems
• Stopping accuracy algorithms and calibration
• Train wake-up and sleep sequences

• Vehicle bus communications (e.g., MVB, Ethernet)

• Develop and manage interface control documents (ICDs), ensuring proper coordination between wayside and onboard systems.

• Collaborate with rolling stock manufacturers, system engineers, and software teams to ensure cohesive system integration.
• Support lab testing, system validation, and on-site commissioning activities.
• Ensure all designs adhere to applicable safety and quality standards including CENELEC EN 50126/50128/50129, IEEE 1474, and IEC 62290.
• Participate in hazard identification, risk assessment, RAMS development, and safety case preparation.
• Engage with stakeholders, including clients and consultants, to align design outputs with project goals.

What do I need to qualify for this role?

• Bachelor's or Master's degree in Electrical Engineering, Electronics, Railway Engineering, or a related technical field.
• Minimum 3–5 years of relevant experience in signalling or train control systems, ideally within CBTC or advanced ATC environments.

• Proven experience with:

• CBTC scheme planning and design

• System-level headway simulation and analysis
• Rolling stock interface definition and validation
• Integration of traction, braking, and stopping control within ATC
• Vehicle communication networks (MVB and Ethernet)

• Trainborne ATC system wake/sleep management

• Strong knowledge of RAMS principles and safety-critical system lifecycle.

• Experience with tools such as AutoCAD, Microstation, DOORS, and signalling simulation platforms.
• Excellent documentation, communication, and problem-solving skills.

• Preferred skills:

• Experience with Siemens CBTC system

• Certification or formal training in CENELEC standards or functional safety
• Experience in multi-vendor project environments and complex integration contexts
