T-ISAC Platform Software Engineer

This is a hands-on engineering role at the heart of GSMA’s TISAC platform transformation. You will be responsible for building, evolving, and maintaining the technical backbone that enables cyber threat intelligence sharing for the global telecoms ecosystem. We’re looking for a T-ISAC Platform Software Engineer who thrives on solving complex architectural challenges, automating large-scale systems, and bringing engineering excellence to a critical industry capability. You’ll work closely with CTI analysts, architecture teams, and platform vendors to deliver a secure, scalable, and resilient T-ISAC service. If you are passionate about infrastructure, automation, API integrations, platform reliability, and delivering secure-by-design services to a global community, this role is your opportunity to help shape the future of telecom security.

The GSMA Industry Security Team is the mobile industry’s focal point for mobile network security. The team is responsible for coordinating GSMA member security working groups, leading industry-wide security initiatives and engaging with global regulators to ensure security is an enabler and not a barrier to next-generation mobile services. The team is responsible for a number of industry-wide cybersecurity schemes including:

• Telecommunications Information Sharing and Analysis Center (T-ISAC).
• Mobile Co-ordinated Vulnerability Disclosure (CVD).
• Network Equipment Assurance Scheme (NESAS).

The Telecommunication Information Sharing and Analysis Centre (T-ISAC) is the cybersecurity threat intelligence community for the telecommunication industry, dedicated to facilitating collaboration and intelligence sharing among mobile network operators, mobile virtual network operators and industry stakeholders. T-ISAC provides GSMA members with critical cyber threat intelligence, fostering a trusted environment where stakeholders can proactively address cybersecurity threats and reduce risks through the development of best practices. By uniting MNOs, MVNOs, manufacturers, service providers and industry in a shared mission, T-ISAC enhances the mobile ecosystem’s resilience against cyber threats.

As the Platform Software Engineer for T-ISAC, you will be responsible for the engineering, operation and continuous improvement of the platforms, tooling and integrations that power the T-ISAC service.

Key Responsibilities

• Platform Engineering & Development: Design, develop and maintain the T-ISAC platform, delivering secure, scalable data workflows, automation capabilities and collaboration tools that support threat intelligence sharing and enrichment.
• Service Reliability & Operations: Lead the operational reliability of the T-ISAC platform through proactive monitoring, incident management, performance optimisation and secure-by-design engineering practices.
• Integration & Interoperability: Deliver and support integrations, APIs and data exchange capabilities that enable secure, scalable intelligence sharing across members and third-party security platforms.
• Platform Roadmap & Technical Strategy: Shape the evolution of the T-ISAC platform by defining future-state architecture, driving technical improvements and evaluating emerging technologies.
• Security & Compliance: Maintain a secure and compliant platform through secure engineering practices, automated controls, vulnerability management and adherence to regulatory and governance standards.
• Collaboration & Community: Foster collaboration across members, analysts, security teams and industry partners to improve platform adoption, effectiveness and community engagement.

You will bring enthusiasm and ownership to this specialised senior role in cyber threat intelligence analysis, joining a dynamic and ambitious team. Your drive will be key to transforming bold ideas into impactful programmes and seeing them through to successful delivery. You will have telecoms experience gained from working at an operator, with an operator or within the wider telecom industry. You will have proven knowledge and expertise in designing, building and operating the core platforms and infrastructure that enable scalable, reliable, secure and efficient software delivery across operations in Intelligence, Cybersecurity, Data Analytics or a related field (equivalent experience will be considered). You will also have experience working with ISACs or other information sharing organisations.

• Analysis: strong analytical, critical thinking and problem-solving skills, with ability to analyse cybersec intelligence.

Essential

• Extensive experience of building and implementing intelligence platforms e.g. OpenCTI, MISP.
• Experience of using collaborative open source tools as part of your analysis and research processes.
• Understanding of nation-state actors, cyber crime, hacktivism and advanced threat actor tactics, techniques and procedures (TTPs).
• Experience in cybersecurity intelligence, including collection, analysis and dissemination.
• Professional experience within the telecom industry, whether gained at an operator, in partnership with an operator, or through work in telecom-related organisations, vendors, academia or the wider mobile ecosystem.

Preferable

• Understanding of mobile data, protocols and technology such as SS7, MOTIF, HRN, IRSF, URLs, GTs.
• Knowledge of mobile network architectures and services.
• Understanding of mobile network and services, threat landscape and the common attacks to which they are exposed.
• Comprehensive understanding of telecommunication industry operations and challenges.
• Expertise in using and applying the Mitre ATT&CK framework, MISP, OpenCTI, Meta, EclecticIQ, governments, law enforcement and other COIs (national and international) for threat analysis and strategy development.
