Top Tech Jobs & Startup Jobs in Mumbai

Perform applied R&D to design, validate, and improve Lightspan SW/HW systems. Validate IP and Layer 2/2+ protocols, build automated tests, troubleshoot complex customer environments, collaborate with R&D/product/support, mentor junior engineers, and drive software architecture and feature enhancements including software upgrades and database migrations.

Leads development of advanced access-network products, including Layer 2 switching, Layer 3 routing, MPLS, and networking control or data-plane software. Designs software architecture and abstraction layers, develops multithreaded C/C++ applications for Linux and RTOS environments, and supports highly available systems, upgrades, migrations, and network management using Netconf/YANG. Requires expertise with GPON/PON, routers, switches, networking protocols, data structures, algorithms, and software quality processes.

Owns quality assurance for carrier-grade optical networking products. Responsibilities include creating test plans, validating system features and customer deployment scenarios, developing test scripts, maintaining automated test frameworks, executing manual and automated tests, analyzing failures and defects, and reporting quality assessments. The role requires testing SONET, SDH, OTN, DWDM, ROADM, optical amplifiers, FCAPS, provisioning, configuration, and protection schemes using optical test equipment and scripting languages.

Define architectures for high-speed coherent interfaces, transponders, and advanced DWDM optical networking systems. Translate customer and market needs into system requirements, lead technical feasibility and feature evaluations, maintain architecture documentation, and coordinate hardware, software, verification, documentation, and product teams from concept through testing. Provide technical guidance across global, cross-functional engineering organizations.

Owns the transition of optical pluggable products from concept through high-volume manufacturing. Responsibilities include design-for-manufacturing and assembly, PFMEA, process qualification, production ramp-up, tooling and fixture development, mechanical component reviews, thermal considerations, and creation of manufacturing documentation. The role coordinates Product Design, Manufacturing, Quality, and related teams while supporting OSFP, OSFP-XD, and QSFP-DD optical transceiver platforms.

Architect coherent optical pluggable products for packet-optical telecommunications systems. Define product requirements and system architecture, collaborate with ASIC, optical, hardware, and software teams, lead cross-functional architecture efforts, evaluate customer and feature requests, validate optical control algorithms and performance monitoring, and document product concepts and specifications.

Design, develop, and operate cloud-hosted e-commerce applications across backend and frontend stacks. Build Node.js services, REST APIs, React.js storefronts, micro frontends, and data solutions using MySQL, NoSQL, Redis, and Memcached. Collaborate with DevOps and SRE teams on containerization, CI/CD, observability, reliable deployments, production troubleshooting, performance tuning, capacity planning, testing, and code quality improvements.

Lead data science efforts by analyzing large datasets, developing and deploying ML models, building scalable data pipelines, designing experiments (A/B testing), creating visualizations, and mentoring junior team members to drive data-driven decisions.

Build end-to-end infrastructure for AI agents: design React/TypeScript UIs, implement Python agent harnesses, develop Kubeflow-based MLOps pipelines, fine-tune foundation LLMs (LoRA/QLoRA/SFT/RLHF), deploy and operate services on Kubernetes, integrate agent frameworks, and apply software engineering best practices, testing, and CI/CD.

Design and implement production-grade AI agent harnesses, build and operate MLOps pipelines with Kubeflow, fine-tune foundation LLMs (LoRA/QLoRA, SFT, RLHF), deploy and manage services on Kubernetes, integrate agent frameworks, and apply software engineering best practices to move models from prototype to production.
