Manage microservices architecture deployed on ARO (a Kubernetes variant).
Integrate with telephony/SMS/MMS/RCS service APIs.
Integrate with LLM APIs such as OpenAI, Gemini and Grok.
Write efficient queries and procedures for Microsoft SQL Server (T-SQL) and MongoDB.
Debug and resolve issues in complex, interconnected systems.
Collaborate with technical and business stakeholders and vendors to gather, refine, and implement rapidly evolving requirements.
Contribute to front-end components as needed using HTML, CSS, and JavaScript.

Desired Qualifications and Skills:

5–10 years of professional software development experience.
Strong proficiency in TypeScript, Node.js, and NPM for server-side development.
Solid experience with HTML, CSS, and JavaScript for web development.
Deep understanding of REST API design, semantics, and frameworks.
Hands-on experience with containerization using Docker and Podman.
Practical knowledge of Kubernetes (including ARO), microservices, and orchestration.
Familiarity with basic telephony and SMS/texting concepts and integrations.
Experience integrating with one or more LLM APIs (e.g., OpenAI, Gemini).
Strong working knowledge of Microsoft SQL Server queries and T-SQL programming.
Proficiency in MongoDB queries, schema design, and development.
Proven ability to work independently as a self-starter in a dynamic, sometimes chaotic environment.
Excellent communication skills to organize complex or ill-defined requirements across technical and business teams.
Expertise in debugging, troubleshooting, and testing interconnected systems.

Highly Valued (Strong Preference):

Hands-on experience with RocketChat installation, configuration, maintenance, integrations, and private application development.
Experience with OpenReplay installation, maintenance, and integration.
