• Experience: 4–6 years of hands-on experience in technical presales, solution engineering, technical consulting, or an application developer role.
• Technical Fluency: Proficient with modern web technologies (e.g., JavaScript, Python, Node.js), HTML/CSS, REST APIs, and utilising webhooks.
• AI Expertise: Practical understanding of AI applications, including utilising LLM-powered features, prompt engineering, and automated workflows.
• Domain Knowledge: Strong understanding of SaaS ecosystems, CX or ES domains, contact center tech (telephony, CRM), or IT support ticketing workflows.
• Travel Commitment: Ability and willingness to travel up to 30% annually for on-site customer discovery and presentation sessions.
• Education: Bachelor’s degree in Computer Science, Business Analytics, Information Systems, or a related technical discipline.

• Hands-on knowledge of cloud data stacks (e.g., Snowflake, Databricks, BigQuery, AWS/Azure/GCP data services) and enterprise BI software (e.g., Power BI, Tableau, Looker).
• Ideally some vertical industry experience, especially in Financial Services, Retail, Travel, Transport & Leisure or Public Sector.
• Active engagement in the technical or developer community (e.g., open-source contributions, technical blogging, or community mentorship).
• Proven track record of designing reusable implementation guides, integration playbooks, or localization toolkits for global delivery partners and systems integrators.
• Experience flattening complex technical narratives into high-impact presentations tailored for executive, economic buyers and C-level stakeholders.

• Customer obsessed: You are dedicated to understanding customer needs and crafting solutions that deliver real value and delight.
• A Builder First: You enjoy writing code, configuring complex systems, and prototyping modern software solutions.
