Job description

Job Description

At Zendesk, we are redefining the boundaries of Customer Experience (CX) and Employee Services (ES) through autonomous, Agentic AI and deep platform extensibility. As we build out the next generation of our global field organization, we are looking for builders, technical problem solvers, and curious minds who want to shape the future of enterprise automation.

We are seeking a technical Sales Engineer (SE) to join our specialized engineering presales team. In this role, you will get your hands dirty writing code, configuring complex API integrations, and building production-ready proof-of-concepts (POCs) that bring our advanced AI capabilities to life. This is a role designed for an engineer who loves solving complex puzzles, working closely with modern web tech stacks, and translating technical possibilities into functional solutions for our customers.

What You'll Be Doing:

• Develop Proof-of-Concepts (POCs): Own the technical execution and delivery of customized product demonstrations, technical sandboxes, and tailored prototypes that prove the power of Zendesk's platform and AI capabilities.

• Build and Maintain API Integrations: Use your coding and scripting skills to connect Zendesk to complex client tech stacks, leveraging REST APIs, webhooks, middleware platforms, and modern cloud infrastructure.

• Own Technical Validation: Partner with account teams to confidently handle deep-dive technical validations, Security/Architecture questionnaires, and developer-to-developer technical reviews.

• Scale Internal Tooling: Collaborate with senior specialists to build, maintain, and document reusable code snippets, demo accelerators, and automation templates that elevate the speed of the entire field team.

• Continuous Technical Learning: Stay on the cutting edge of modern software trends, actively developing your skills in Large Language Models (LLMs), prompt engineering, and autonomous agent frameworks.

What You Bring (Required Qualifications):

• Education: Bachelor’s degree in Computer Science, Business Analytics, Economics, Statistics, or a related highly quantitative, technical discipline.

• Experience: 2 to 4 years of professional experience in a technical client-facing role (e.g., Solution Engineer, Sales Engineer, Technical Support Engineer, Implementation Consultant) or as a hands-on Software Developer looking to pivot into a strategic field role.

• Core Technical Skills: Hands-on experience or academic proficiency with modern programming languages and web technologies (e.g., JavaScript, Python, Node.js) and working with REST/SOAP APIs.

• Technical Curiosity: A strong foundational interest in AI technologies, including prompt engineering, LLMs, and autonomous software workflows.

• Travel Commitment: Ability and willingness to travel between 30% and 50% annually for on-site technical workshops, team collaboration, and client validation sessions.

Preferred Qualifications:

• Familiarity with enterprise software infrastructure, cloud ecosystems (AWS, GCP, or Azure), or modern contact center architectures.

• Experience presenting technical or architectural concepts clearly to both technical and non-technical audiences.

• A portfolio of personal projects, GitHub contributions, or technical blogs that demonstrates your passion for building.

Who You Are:

• A Continuous Learner: You love dissecting new technologies and frameworks; you don't wait for a training module to learn how something works under the hood.

• An Execution-Focused Builder: You thrive when given a complex technical problem, a blank IDE, and a deadline to build a working prototype.

• A Strong Communicator: You can sit across from a customer's developer, understand their stack, and explain technical solutions in a highly collaborative, approachable way.
