About the roleThe Technical Account Manager serves as the primary technical advisor and advocate for our most strategic enterprise customers. You'll combine deep technical expertise with strategic relationship management to ensure customers maximise the technical value of our platform, optimise performance and reliability, and successfully scale. This role bridges the gap between customer technical teams and our product, engineering, and support organisations, acting as a trusted technical partner throughout the customer lifecycle.
Provide expert guidance on platform capabilities, technical best practices, optimisation strategies, and technical roadmap planning. Conduct regular technical health reviews (monthly/quarterly) assessing system performance, architecture, integrations, security posture, and usage patterns.
Develop deep understanding of customer's technical environment, architecture, workflows, and strategic technical initiatives. Act as technical voice of customer internally, representing their technical needs and perspectives to product and engineering teams
Collaborate with the customer on technical health continuously through usage metrics, performance data, error logs, API analytics, and system health indicators. Identify technical risks proactively before they impact customer operations—capacity constraints, performance degradation, integration issues, deprecated features, or scaling bottlenecks. Conduct proactive outreach when anomalies, concerning patterns, or potential issues are detected.
Analyse customer usage patterns and provide optimisation recommendations to improve performance, reliability, scalability, or cost efficiency. Create technical success plans with specific technical objectives, milestones, success criteria, and optimisation roadmaps. Perform regular technical reviews of customer implementations identifying areas for improvement or modernisation.
Drive adoption of advanced features, APIs, integrations, and technical capabilities that deliver additional value. Provide technical training and enablement for customer development teams, operations teams, and technical staff. Share technical documentation, code samples, integration patterns, API best practices, and reference architectures.
Enable customer self-sufficiency in troubleshooting, optimisation, configuration, and platform usage. Conduct technical workshops, lunch-and-learns, and deep-dive sessions on specific capabilities or use cases. Guide customers through new feature adoption from technical evaluation through implementation and production deployment.
Advise on integration strategies, API usage patterns, and architectural approaches for connecting platform to customer's technology ecosystem. Review and provide feedback on integration architectures ensuring scalability, reliability, security, and performance.
Guide customers on best practices for common integration patterns (real-time vs. batch, webhook vs. polling, data synchronisation strategies). Troubleshoot complex integration issues spanning multiple systems and technologies. Assist with technical planning for new integrations or major architectural changes.
Bridge communication between customer technical teams and internal engineering teams, translating technical issues in both directions. Support post-incident reviews for major technical issues, assisting in the documentation of root causes, remediation steps, and preventive measures.
Provide guidance on security best practices, authentication methods, authorisation models, and data protection. Support customers through security audits, penetration testing, and vulnerability assessments.
