Client Support Lead

We are looking for a technically sharp and client-focused Client Support Lead to own the post-sales technical relationship with our enterprise customers. In this role, you will lead a small team of two Support Specialists, providing mentorship, workload guidance, and technical escalation support while remaining highly hands-on yourself. You will be the bridge between our clients and our engineering teams, ensuring rapid resolution of complex issues across our distributed, cloud-native platform. This role demands both deep technical ability and the communication skills to translate complexity into clarity for customers and stakeholders alike.

Team Leadership

• Manage, mentor, and support two Support Specialists in their day-to-day work and professional development.
• Distribute and prioritise incoming client issues across the team, ensuring SLAs are met and no ticket falls through the cracks.
• Conduct regular 1:1s, provide constructive feedback, and help the team build their technical depth over time.
• Act as the primary escalation point within the support team before issues reach engineering.

 

Client & Escalation Management

• Serve as the primary senior technical contact for enterprise clients, owning issue resolution from intake through closure.
• Lead escalation handling for critical production incidents, coordinating internal engineering resources and communicating clearly with clients under pressure.
• Produce high-quality written incident summaries, root cause analyses, and post-mortems for customer delivery.
• Build and maintain trusted relationships with client technical teams, proactively identifying risks before they escalate.

 

Technical Investigation & Debugging

• Perform deep-dive investigations across the full stack: REST APIs, application logs, distributed traces, and database query analysis.
• Debug issues spanning C#/.NET (ServiceStack) services, MongoDB, SQL Server, Redis, and RabbitMQ message queues.
• Analyse CloudWatch, Grafana, and Prometheus metrics to isolate performance bottlenecks and anomalies.
• Use Postman and cURL to reproduce, isolate, and document API-level defects.
• Read and interpret .NET stack traces to pinpoint root causes and communicate findings to engineering teams.

 

Infrastructure & Environment Support

• Support deployment and troubleshooting of virtual environments across AWS (EC2, ECS, EKS) and on-premise infrastructure.
• Work confidently across Linux and Windows, with solid grounding in networking fundamentals (DNS, TCP/IP, TLS, load balancing).
• Assist clients with Docker-based deployments, container orchestration issues, and environment configuration.

 

Process & Tooling

• Track, triage, and prioritise client issues in Jira; maintain accurate documentation in Confluence.
• Contribute to runbooks, FAQs, and internal knowledge bases to enable the team to resolve issues faster and more consistently.
• Continuously improve support workflows, escalation paths, and tooling to scale the support function.
