Top Tech Jobs & Startup Jobs

Develops and optimizes high-volume assembly processes for electro-optical modules. Responsibilities include SMT and microelectronics assembly, mechanical and thermal analysis, manufacturing data processing, yield improvement, failure analysis, prototype assembly, assembly documentation, contract manufacturer coordination, and technical support. The role bridges product development and manufacturing, ensures volume manufacturability and quality compliance, and requires international travel to manufacturing sites.

Develops electrical, optical, and thermal test plans, algorithms, hardware, software, and automated production test solutions for photonic integrated circuits. Responsibilities include device characterization, instrument control, motion and vision systems, test station qualification, Gage R&R, SPC, documentation, data analysis, troubleshooting, and cross-functional project coordination.

Provides senior-level support and maintenance for transport IP, data, core, and aggregation networks. Configures and troubleshoots Cisco, Juniper, and Fortinet infrastructure; routing protocols; MPLS; VPNs; firewalls; and network security controls. Monitors performance, resolves protocol-level incidents, coordinates managed services operations, and communicates with customers. Requires advanced networking expertise, CCNP/JNCIP-level knowledge, and participation in 24x7 on-call support.

Designs, develops, optimizes, tests, and supports IP networking solutions for high-performance service provider and enterprise environments. Responsibilities include creating high- and low-level network designs, ensuring protocol compliance, troubleshooting complex issues, developing migration scripts, automating design and deployment processes, and collaborating with architects, security, operations, and DevOps teams. The role requires extensive IP/MPLS, routing, service provider, Cisco, and Juniper expertise.

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.

Lead the integration, calibration, testing, and performance optimization of optical modules for coherent optical transponder line cards. Develop testing methodologies and calibration procedures, troubleshoot complex optical systems, collaborate with cross-functional teams, and produce technical documentation including test plans, procedures, and reports.

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.

Optimizes multi-vendor 2G, 3G, 4G, LTE/VoLTE, and 5G radio networks. Analyzes network performance, troubleshoots poor cell performance, tunes radio parameters, conducts root cause analysis, prepares SLA and KPI reports, supports site acceptance, and collaborates with customers to improve coverage, capacity, quality, and user experience.

Develop and maintain user-focused technical documentation for software and hardware products, including user guides, online help, knowledge base articles, and release notes. Collaborate with engineers, product managers, support teams, and subject matter experts throughout the documentation lifecycle. Gather and validate information, edit content, support publication, incorporate feedback, and improve documentation quality, accessibility, usability, tools, and processes.

Designs, models, integrates, tests, and validates electro-optical subsystems for high-speed optical communication systems. The role develops requirements, link budgets, signal integrity analyses, test methodologies, and technical documentation; performs laboratory characterization and root-cause analysis; leads integration activities; and supports product qualification and production readiness in collaboration with optical, hardware, DSP, FPGA, firmware, manufacturing, and product engineering teams.
