Software Engineer - Developer Advocate at Crexendo — San Diego, USA | Base Career

Join an established enterprise communications company at an exciting inflection point — where a mature, battle-tested platform meets a bold new wave of innovation.

We're building our developer advocacy function and looking for an engineer-minded communicator who can bridge the gap between our UCaaS API platform and the developers, partners, and clients who build on top of it.

You'll play a role in that effort — building demo applications, presenting to clients, and crafting the documentation for partners and developers to integrate with our platform.

If you love the craft of engineering but get just as energized explaining it, this role was built for you.

Write and maintain developer-facing API documentation for new and existing features
Collaborate closely with the engineering team to gain deep understanding of platform capabilities
Translate technical implementation details into clear, accurate, and useful documentation for external developers
Create code examples, guides, and reference material that accelerate developer onboarding

Present demo applications to clients, system integrators, and technology partners
Clearly explain REST API concepts and integration patterns to both technical and semi-technical audiences
Represent the engineering team in client-facing settings with confidence and clarity

Build demo applications that show case real-world use cases of our UCaaS REST API
Create and showcase demo extension applications for our Horizon platform using our UI SDK integration tool

Maintain a strong security posture by adhering to all company information security policies and procedures.
This includes, but is not limited to, protecting customer data from unauthorized access, maintaining the confidentiality of sensitive information, adhering to established availability protocols, and participating in mandatory annual security awareness training.

Solid engineering fundamentals with the ability to understand, consume, and explain REST APIs
Hands-on experience building applications that integrate with third-party APIs
Strong written and verbal communication skills
Comfortable presenting technical concepts to clients and partners

Self-starter who can work independently and manage multiple workstreams
Detail-oriented with a commitment to clear, accurate technical writing
Collaborative — able to work with engineers to extract and communicate deep technical knowledge
Confident public speaker who can engage diverse audiences

UCaaS, VoIP, SIP or telecommunications experience
Prior experience writing API documentation or developer guides
Developer relations or technical advocacy background

Creative freedom building demo applications on a rich UCaaS API platform
Close collaboration with the engineering team — you'll always know the "why" behind the platform
Flexible work arrangements — hybrid schedule available for San Diego and Phoenix area candidates
Comprehensive benefits package and competitive compensation
