Network Architect - Air Traffic Management

ALTEN Group is a world leader in Engineering and Technology consulting services providing outsourced Engineering, R&D, and IT Services for different industries such as Transportation, Defence, Energy and Security with 55,000 engineers in nearly 35 countries. ANOTECH is the subsidiary of the Group delivering ALTEN's Engineering Services in Singapore.

As a Network Architect, you will play a key role in designing and modelling complex, safety-critical ATM solutions within the organisation’s advanced portfolio (e.g., TopSky ATM, digital towers, and SWIM-enabled platforms). This role sits at the intersection of system engineering, network architecture, and operational aviation environments, supporting end-to-end lifecycle delivery in alignment with the organisation’s V-cycle engineering model and Agile (SAFe) practices.

Responsibilities

·        Requirements Analysis and Operational Understanding

Ø  Analyze and synthesize customer and operational needs across ATM environments (ACC, approach, tower).

Ø  Leverage simulations, prototypes, and real operational scenarios to define robust solution requirements.

Ø Ensure alignment with ICAO,SESAR, and customer-specific regulatory frameworks.

·        Solution Co-Engineering(Multi Domain Integration)

Ø  Collaborate across software, hardware, cybersecurity and IVV (Integration, Verification and Validation) engineering domains.

Ø Co-engineer end-to-end ATM network solutions (e.g., surveillance data distribution, voice communications, SWIM integration).

Ø Balance performance, safety, cost, and delivery considerations in system design

·        System Specifications and Interface Design

Ø  Define and formalize:

v  Network architectures (IP/MPLS, secure communications)

v  System and subsystem specifications

v  Interfaces between ATM components (radar, VCS, flight data processing systems)

Ø Ensure interoperability across legacy and next-generation in-house solutions

·        Functional Architecture Modelling

Ø  Develop functional and logical architectures using UML/SysML modelling techniques.

Ø  Support architecture governance within the organization’s engineering frameworks.

Ø  Contribute to system decomposition, data flow design, and service-oriented architectures(SOA/SWIM).

·        Technical Leadership and Liaison

Ø  Act as the technical focal point between:

v  Development teams

v  IVV teams

v  Program managers and customers

Ø  Provide technical clarity on system integration challenges and design decisions.

Ø  Support design reviews and customer workshops

·        Verification, Validation& Lifecycle Support

Ø  Support definition of test strategies, procedures, and validation plans.

Ø  Ensure full traceability from requirements to validation within DOORS.

Ø  Contribute to system acceptance and deployment activities

·        Process Improvement &Innovation

Ø Drive continuous improvement aligned with the organization’s engineering excellence initiatives.

Ø Promote best practices in:

v Model-based systems engineering (MBSE)

v Agile (SAFe) delivery

v Knowledge sharing within global teams
