Position Overview

We are seeking an experienced and hands-on Optical System Engineer with a deep background in data communication systems and optical transceiver integration at the switch and rack level. This role is central to the validation and system-level testing of high-speed optical interconnects (400G/800G/1.6T), ensuring seamless performance within hyperscale and cloud data center environments.

The ideal candidate is proficient in both the electrical and optical domains, capable of bridging transceiver-level performance with system-level functionality across switches, servers, and racks to solve complex integration challenges.

Key Responsibilities

• Lead optical system validation and integration at the switch and rack level, including end-to-end path testing from transceivers to host systems.

• Perform optical link bring-up, functional validation, and stress testing of 400G/800G/1.6T modules across various switch platforms.

• Design and execute comprehensive test plans to evaluate performance under realistic data center configurations and traffic loads.

• Analyze system-level performance metrics such as BER, signal integrity, power budget, insertion loss, and FEC margins.

• Collaborate with Signal Integrity (SI) teams to validate host-board compatibility and optimize performance.

• Partner with hardware, firmware, and transceiver vendors to troubleshoot and resolve cross-layer integration issues.

• Drive root cause analysis for failures identified during validation and document findings and corrective actions.

• Develop and maintain automated test setups and scripts using Python or other scripting tools.

• Interface with network architects and deployment teams to translate system requirements into detailed validation specifications.

Required Qualifications:

• Bachelor’s or Master’s degree in Optical Engineering, Electrical Engineering, Physics, or a related field.

• 3+ years of hands-on experience in optical system validation or integration within datacom or telecom environments.

• Deep understanding of optical transceivers (e.g., QSFP-DD, OSFP), fiber connectivity, and high-speed signaling principles.

• Direct experience working with switch ASIC platforms and network hardware.

• Familiarity with Ethernet standards: IEEE 802.3bs, 802.3ck, 802.3dj, etc.

• Hands-on proficiency with test instruments including BERTs, oscilloscopes, optical power meters, and protocol analyzers.

• Proficiency in scripting languages (e.g., Python, Bash) for test automation and data analysis.

• Proven experience in lab environments managing test fixtures, fiber handling, and cabling.

Preferred Qualifications:

• Familiarity with data center network architectures (e.g., leaf-spine topology, TOR switches, AI/ML cluster designs).

• Experience with Common Management Interface Specification (CMIS), Digital Diagnostic Monitoring (DDM), and transceiver diagnostics.

• Understanding of thermal, EMI, and mechanical constraints in rack-level integration.

• Knowledge of emerging technologies such as silicon photonics, co-packaged optics (CPO), or linear-drive pluggable optics (LPO).

Benefits

We offer a comprehensive benefits package designed to support our employees' health, and well-being, including:

• Health, dental, and vision coverage

• 401(k) retirement plan with company matching

• Wellness programs and employee support resources

• Life and disability insurance

• Paid time off and company holidays
