Senior Developer

Overview 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.

Responsibilities 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.

Requirements

• 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.

Preferred Qualifications

• 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 fast-paced product startup or digital transformation programme within a consulting or telco context.
