• Safeguard network security by implementing strong controls, managing firewalls and access policies, conducting vulnerability assessments, and staying ahead of emerging cyber threats in telecare environments.
• Ensure compliance with UK GDPR, the Data Protection Act 2018, and TSA standards, protecting the personal data of vulnerable service users through secure firewall, VPN, and network access configurations.
• Deliver clear technical guidance to customers, housing providers, local authorities, and partners on network connectivity, IP configuration, and digital telecare integrations—remotely and on-site.
• Monitor and optimise network performance, analysing capacity and availability to reduce First Time Call Failures (FTCFs) and improve reliability of digital careline services.
• Manage third-party providers, working with ISPs and telecoms partners to maintain service levels and support the transition to All-IP services.

• Demonstrated troubleshooting expertise, including diagnosing and resolving complex network issues using tools such as Wireshark, SIP tracing, and packet capture utilities.
• Excellent problem-solving skills, able to work calmly and methodically in high-pressure scenarios where uptime directly impacts safety and wellbeing.
• Clear communicator, capable of producing high-quality technical documentation and delivering step-by-step guidance to colleagues, customers, and non-technical stakeholders.
• Relevant technical qualification in networking, telecommunications, or IT (e.g. Cisco CCNA/CCNP, CompTIA Network+, or equivalent).
• Hands-on experience with IT infrastructure and IP configuration, including routers, switches, firewalls, and SIP/VoIP systems in live operational environments.
• Experience in technical support environments, including incident management, change control, and service improvement activities.
• Proficiency with Microsoft tools, including Excel, Teams, and related platforms for reporting, documentation, monitoring, and collaboration.

Desirable Requirements

• Experience or knowledge of the Telecare / Technology Enabled Care (TEC) sector, particularly the transition from analogue PSTN to digital All-IP services.
• Familiarity with telecare standards and protocols, including TSA Code of Practice, BS 8521-2 (NOWIP), and SCAIP / CENELEC TS 50134-9.
• Additional IT or service management qualifications, such as ITIL Foundation, CompTIA Network+ (if not already held), or relevant security certifications.
