Job Description

Join Our Dynamic Team as a L3 Support Engineer! 🌟 

Are you passionate about telecoms? Do you thrive in a fast-paced, innovative environment? At Babble, we’re on a mission to be our customer’s most trusted advisor for cloud-based technologies. We’re looking for passionate and talented individuals to join our dynamic team. If so, we have the perfect opportunity for you!  

Purpose of the Role

The L3 Support Engineer is the senior technical authority within the Babble Professional Services team and a hands-on technical delivery resource. The core focus of the role is the technical implementation, configuration and deployment of customer solutions across Modern Workplace, Cyber Security, Network and Backup/DR domains. Operating as a Level 3 Engineer, the role leads and performs hands-on deployment on complex, high-risk and multi-domain projects and sets the technical standard for how solutions are built and configured across the team. 

The role also owns the design phase of customer engagements, producing High-Level Designs, Low-Level Designs and Statements of Work that translate requirements into buildable, production-ready solutions. Design and deployment are treated as a single continuum: the Solutions Architect is accountable for the technical quality of the solution from design through to a working, tested and handed-over deployment, and stays hands-on throughout. 

Key Responsibilities

• Lead hands-on implementation on complex, high-risk or multi-domain projects including Azure Virtual Desktop deployments, complex network architectures, multi-tenant security configurations, hybrid identity environments, and large-scale migration programmes. 
• Produce High-Level Designs and Low-Level Designs for customer solutions across Modern Workplace, Cyber Security, Network and Backup/DR domains, defining the technical architecture, configuration specifications, integration requirements, and dependencies that form the basis of all Professional Services delivery. 
• Author Statements of Work that clearly define project scope, deliverables, assumptions, exclusions, acceptance criteria, and delivery milestones, ensuring commercial and technical alignment between what has been sold and what will be delivered. 
• Provide technical guidance and design assurance throughout the delivery lifecycle, reviewing implementation progress against HLD/LLD specifications, validating configuration decisions made by fellow engineers and advising on deviations from the approved design where necessary. 
• Act as a senior technical resource for the wider Professional Services team, providing guidance on design ambiguities, environment conflicts, vendor-specific technical issues, and scope boundary questions to support effective project delivery across all levels. 
• Support pre-sales technical activities including customer scoping calls, solution qualification, technical feasibility assessments, and design input for proposals, ensuring opportunities are technically sound and deliverable before commitment to Statement of Work. 
• Conduct technical design reviews with customers to validate requirements, confirm design assumptions, identify risks, and secure sign-off on the proposed solution architecture before delivery commences. 
• Define and maintain technical standards, deployment checklists, configuration baselines, and design templates used across the Professional Services team, ensuring consistency and quality across all project deliveries. 
• Validate UAT results and technical acceptance for projects where the Solutions Architect has produced the design, confirming that the delivered solution meets the specifications defined in the HLD/LLD and Statement of Work. 
• Mentor and develop Level 1 and Level 2 engineers through technical guidance, design reviews, knowledge sharing and structured feedback, actively supporting career progression and capability uplift within the Professional Services team. 
• Collaborate with the Service Desk, NOC, and managed services teams to ensure solutions are designed for operational supportability, including monitoring requirements, escalation paths, documentation standards, and ongoing managed service compatibility. 
• Contribute to vendor relationship management by maintaining advanced certifications, attending vendor technical briefings, evaluating new product capabilities, and advising on the evolution of the Babble solution portfolio. 
• Identify and communicate project risks, design constraints and technical dependencies to Project Managers, the Solutions Delivery Manager and customers, providing clear recommendations and mitigation options to support informed decision-making. 
• Lead post-implementation design reviews on complex projects, evaluating design effectiveness against delivery outcomes, capturing lessons learned and feeding improvements back into design standards and templates. 
• Maintain expert-level technical skills and advanced vendor certifications across the Babble solution portfolio, staying current with platform roadmaps, architectural best practices and emerging technologies across Microsoft, Mimecast, Sophos, Acronis, networking, and cloud infrastructure. 

Qualifications

• Extensive experience of solution design and delivery across all four domains (Modern Workplace, Cyber Security, Backup/DR and Networking) and Azure. 
• Demonstrable design authorship (High-Level Designs, Low-Level Designs and Statements of Work) and pre-sales technical experience. 
• Track record of mentoring and raising the technical capability of a delivery team. 

Desired Certifications 

• Microsoft Certified: Azure Solutions Architect Expert (AZ-305), or its current Microsoft successor certification. 
• Microsoft Certified: Cybersecurity Architect Expert (SC-100), or its current Microsoft successor certification. 
• Microsoft 365 Certified: Administrator Expert (MS-102), or its current Microsoft successor certification. 
• Sophos Certified Architect for Sophos Firewall and Sophos Central Endpoint/Server (each requires the corresponding Sophos Certified Engineer certification as a prerequisite). 
• Acronis Certified Engineer (Cyber Protect). 
• Mimecast Certified Product Professional, Advanced level (Email Security, Cloud Gateway). 

Advantageous Certifications 

• PRINCE2 7th Edition Practitioner, or equivalent project management certification (for example PMP or APM PMQ). 
• ITIL 4 Foundation (or ITIL Version 5 Foundation) in IT service management. 
• CISSP (ISC2), or equivalent senior security certification; CompTIA Security+ (SY0-701) is an acceptable foundational alternative. 
• CrowdStrike Falcon certifications such as CrowdStrike Certified Falcon Administrator (CCFA) or Falcon Responder (CCFR), and familiarity with the Falcon Complete managed detection and response service.
