Senior Developer

We are looking for a Senior Developer with strong telecom domain exposure to design, build, and maintain high-quality software components across OSS/BSS, network automation, and digital platform engagements. This is a hands-on engineering role — you will own individual modules end-to-end, write clean and well-tested code, and provide technical guidance to junior developers, while working closely with the Technical Lead on design and delivery.

Key Responsibilities Design and develop scalable, secure, and maintainable software applications. Analyze business and technical requirements and translate them into effective solutions. Write clean, efficient, reusable, and well-tested code. Review code and provide constructive feedback to ensure engineering best practices. Troubleshoot complex production and application issues. Participate in architecture and technical design discussions. Mentor junior and mid-level developers. Collaborate with cross-functional teams including Product, QA, DevOps, and UI/UX. Develop and maintain automated unit, integration, and regression tests. Contribute to CI/CD, deployment, monitoring, and performance improvements. Identify technical debt and recommend improvements to existing systems. Stay current with emerging technologies and recommend suitable tools and practices. Required Skills & Qualifications CORE RESPONSIBILITIES Design, build, and maintain features across the full stack: frontend (React/Next.js), backend (Node.js/Python), and data/API layers. Integrate AI/ML capabilities into the product UI/UX - streaming LLM responses, agentic workflow visualisations, and intelligent data displays. Build and consume RESTful and GraphQL APIs; own the contract between frontend and backend within the squad. Develop and maintain CI/CD pipelines for frontend and backend services; ensure code ships reliably to production. Collaborate closely with UX/design to translate wireframes and prototypes into responsive, accessible, production-grade interfaces. Write unit, integration, and end-to-end tests; maintain high coverage across frontend components and backend services. Participate in architecture discussions, code reviews, and sprint planning; contribute to shared platform libraries and design systems. Support customer-facing demos and PoC builds by rapidly prototyping new features with production-quality code. MUST-HAVE SKILLS & EXPERIENCE Strong proficiency in modern frontend: React (hooks, context, concurrent mode), Next.js, TypeScript, and CSS-in-JS or Tailwind. Solid backend engineering in Node.js and/or Python (FastAPI, Django, Flask); REST and GraphQL API design and implementation. Experience integrating LLM/AI APIs (OpenAI, Anthropic, Gemini) into product interfaces - streaming, function calling, embeddings. Comfortable with relational (PostgreSQL) and NoSQL (MongoDB, Redis) databases; basic query optimisation and schema design. Proficiency with Docker, cloud deployment (AWS / Azure / GCP), and CI/CD tooling (GitHub Actions, Vercel, or equivalent). Familiarity with state management (Zustand, Redux Toolkit), component libraries, and responsive/accessible design principles. Working knowledge of vector stores and RAG UI patterns - displaying retrieved context, citations, and confidence indicators.

Experience with real-time features: WebSockets, Server-Sent Events (SSE), or streaming APIs for live AI output rendering. Mobile development exposure: React Native or PWA patterns for cross-platform delivery. Familiarity with observability tooling (Datadog, Sentry, OpenTelemetry) and frontend performance profiling. Telecom domain awareness: BSS/OSS UI workflows, network operations dashboards, or OSS portal development.

S. / M.S. in Computer Science, Software Engineering, or equivalent practical experience. Portfolio of shipped products or open-source contributions demonstrating full-stack breadth and AI/LLM integration. Prior experience in a
