Available Locations - Lisbon
What You'll Do:
As a Senior Technical Support Engineer for the Developer Platform, you will be on the front line supporting developers building on Cloudflare's developer products (Workers, KV, R2, D1, Durable Objects, Vectorize, AI Gateway, etc.). You'll help troubleshoot issues, guide customers in best practices, and ensure they are successfully building, deploying, and scaling applications on Cloudflare.
This is a foundational role in a new and growing team, offering the chance to shape our support processes and culture.
This is a hands-on, developer-focused role where you'll combine your problem-solving skills with your understanding of modern developer tooling, coding practices, and cloud infrastructure. You'll collaborate with internal engineering, product, and developer relations teams to make sure customer feedback is heard and that developers have an excellent experience with the platform.
Responsibilities:

• Act as the first point of contact for developer customers seeking support with Cloudflare's developer platform.
• Troubleshoot technical issues across compute, storage, and networking (e.g., debugging Workers scripts, diagnosing KV/D1 queries, resolving API errors).
• Provide clear, actionable guidance to customers, translating complex technical concepts into understandable steps.
• Triage customer issues and work closely with engineering to drive both short term resolution and long-term improvements.
• Create and maintain support documentation, knowledge base articles, and sample code snippets.
• Escalate recurring issues and surface developer insights to product and engineering teams to improve the platform.
• Collaborate cross-functionally with Developer GTM and sales to ensure customers can move from experimentation to production smoothly.
• Contribute to process improvements that make support more efficient and developer-friendly.

Skill Requirements

• 3+ years experience in a customer-facing technical role (e.g., Technical Support, Solutions Engineer, or Software Engineer) at a cloud and/or SaaS provider.
• Hands-on experience with web application development (professional or personal projects), ideally full-stack using modern JavaScript frameworks (React, Vue, Node.js, etc).
• Excellent written and verbal communication skills with the ability to explain technical concepts clearly.
• Customer-first mindset with patience, empathy, and strong problem-solving skills.
• Familiarity with the major cloud providers (AWS, GCP, Azure) and common cloud services.
• Strong understanding of developer workflows (version control, CI/CD, package managers, API integrations, and frameworks).
• Comfort with debugging code, reviewing logs, and testing APIs.

Other Desirable Skills Include

• Experience building or deploying applications on Cloudflare Workers.
• Understanding of distributed systems and serverless architecture.
• Familiarity with relational and non-relational databases.
• Experience contributing to open source or engaging with developer communities.
• Certifications such as AWS Solutions Architect or GCP Cloud Architect is a plus.
• Auxiliary knowledge of developer tooling and relevant framework is a plus.
• Understanding of AI concepts and experience using AI models in real-world applications.
