What You'll Be Doing: Own the Customer Experience: Serve as the primary point of contact (L1) for our business and communication application users, delivering timely and professional support. Investigate and Resolve: Efficiently troubleshoot, reproduce, and document customer issues end-to-end within our ticketing system. Drive Process Improvement: Identify and report on recurring technical issues, contributing insights to reduce future problems and enhance product stability. Build Knowledge: Maintain and expand our internal Knowledge Base and refine IT process templates for better team efficiency. Communicate Clearly: Translate complex technical issues into clear, actionable updates for customers, ensuring swift incident resolution.

🎯 Your Impact: You will lead the design and maintenance of mission-critical, real-time voice systems. Your focus will be on ensuring unparalleled reliability, scalability, and security while enhancing voice quality and observability across our global cloud infrastructure. Key Responsibilities: Architect & Optimize: Design, develop, and maintain high-performance SIP and RTP-based VoIP systems, serving as the subject matter expert on core VoIP protocols. Deep Troubleshooting: Utilize expert-level skills to diagnose and resolve complex routing, codec, and signaling issues using packet captures (Wireshark), logs, and SIP traces. Protocol & Network Tuning: Proactively optimize network performance across critical protocols (SIP, RTP, TCP/IP, DNS, NAT, and firewall rules). Ecosystem Integration: Integrate, support, and ensure seamless interoperability between PBX systems, SBCs, and modern cloud VoIP environments. Quality Assurance: Define, monitor, and aggressively improve call quality metrics (MOS, jitter, latency) through proactive performance tuning. Feature Leadership: Lead the technical architecture and deployment of advanced voice applications, including real-time transcription, AMD/VMD (Answering Machine Detection), and next-generation AI-driven voice features. Escalation Point: Act as the final point of technical escalation for intricate VoIP incidents, effectively coordinating with internal teams and external vendors.

Founding Engineer (Agentic Intelligence) We are building the intelligence layer for fragmented global markets. The world’s most valuable data isn't sitting in clean APIs—it’s trapped in thousands of unstructured open sources, from massive enterprise portals to obscure individual websites. We are building an autonomous agentic system that doesn't just crawl the web; it reads, reasons, and reports. As our first hire, you will move beyond simple ETL to architect a "market brain" that distills chaos into institutional-grade clarity. The Mission: Architect the Stack: Design the infrastructure for a system that interprets the web in real-time. Build the Engine: Create the core reasoning loops that allow our agents to navigate and analyze complex data environments. Lead the Evolution: Transition from lead builder to engineering leader as we scale the team and the product.

Job Description We are hiring a Senior LLM Systems / Agent Infrastructure Engineer to optimize and scale a production multi-agent LLM system that translates natural language into Cypher / SQL queries, executes guarded graph retrieval, and synthesizes structured RAG responses. You will engineer a faster, cheaper, and more reliable LLM system in production.
