This is a deep technical role, not a people-management role. You will spend your time designing and building, work across cloud backend microservices, serverless components, and systems-level software, and raise the technical bar through hands-on contribution. Prior SIP/VoIP or contact-center experience is a plus, not a strict requirement. If you enjoy complex distributed systems, production ownership, and solving hard problems while continuing to learn a specialized domain, this is a high-impact opportunity. Key Responsibilities The primary responsibilities for this role include (but are not limited to): Design, develop, and deliver scalable cloud backend and voice-platform services that support real-time communications with high reliability and operational excellence. Hands-on implement backend microservices in Java and Spring Boot, along with Python-based serverless functions (AWS Lambda) for event-driven and automation workloads. building AI bots, agents using latest tech stack like MCP, RAG, vector database, guardrails, langchain framework. Develop and maintain systems software in C, including work with network-facing and open-source platform components (e.g. OpenSIPS/SIP routing) used in real-time communications. Contribute to full-stack features, including React-based UIs and operational tooling, where needed. Build and operate services on AWS, ensuring scalable, observable, and production-ready solutions. Apply strong networking and Linux systems skills to develop, integrate, and troubleshoot real-time communications workloads. Apply deep understanding of multithreading, concurrency, and thread-safety to design and troubleshoot high-throughput, low-latency services. Build fluency in SIP/VoIP and Genesys voice-platform concepts and apply them effectively in your work. Own troubleshooting of complex production issues spanning networking, systems, and service layers; drive root-cause analysis and lasting fixes using observability tooling such as SumoLogic and New Relic. Drive strong system design: translate ambiguous requirements into clear architecture, make sound trade-offs, and document decisions for scalability, fault tolerance, and maintainability. Collaborate with product, architecture, DevOps, QA, security, and operations to translate business and platform needs into durable technical solutions. Champion engineering best practices for design, code quality, CI/CD, testing, monitoring, logging, tracing, and production operations. Provide technical guidance and mentorship through design reviews, code reviews, and hands-on collaboration (individual contributor; no direct reports). Drive continuous improvement in system performance, availability, scalability, fault tolerance, and maintainability across the voice platform. Minimum Requirements 7+ years of professional software engineering experience as a hands-on individual contributor, including staff/principal-level technical impact. Proven ability to drive technical initiatives from architecture through production delivery. Ability to provide technical guidance and influence engineering direction without formal authority. Strong communication skills across engineering, product, and operations. Experience supporting mission-critical, high-availability production systems. Strong system design and analytical/problem-solving skills. Ability to learn SIP/VoIP and real-time communications concepts quickly. Ability to balance quality, performance, security, and delivery timelines.

Experience building AI-powered features or internal tooling: integrating LLM APIs (AWS Bedrock), MCP servers/agents, RAG pipelines, embeddings, or vector databases. Experience applying AI/LLMs to observability and operations (e.g. automated log analysis, incident summarization, runbook generation). Awareness of AI safety, prompt-injection risks, and secure handling of code and data with third-party AI tools. Architecture: Microservices and distributed systems design and operation. Concurrency: Deep understanding of multithreading, thread lifecycle, synchronization, and thread-safety.
