Optical Engineer, RTP, Test Software Architecture and Optics NPI

Optical Engineer, RTP, Test Software Architecture and Optics NPI Responsibilities Architect, build, and maintain Python-based test software infrastructure and frameworks for automated qualification of optical transceivers and subsystems (EVT/DVT/PVT/characterization), spanning instrument drivers, switch/host abstractions, and results pipelines • Lead optics NPI programs end to end, working closely with optics vendors and ODMs from RFI/RFP through EVT/DVT/PVT to mass production (MP) ramp and sustaining • Find, debug, and remediate optical hardware failure modes before certifying modules for mass production; drive root-cause analysis and corrective action with vendors and ODMs • Stand up and own NPI test stations in Meta's lab regions: integrate modules, switches, and instruments, and debug at-scale, lights-out test execution • Define test and measurement methodologies for high-speed optical technologies, and translate them into reusable, well-tested automation • Develop instruments, automation, and integration (BERT, OSA, optical power/wavelength meters, scopes) and CMIS register-level module control • Ensure new optical platforms are supported by production and fleet-health tooling, and contribute to production-readiness documentation (PRD), Best Known Configuration (BKC), and Design-for-Test (DFT) • Drive data integrity and analysis: build robust data capture, storage, and visualization (e.g., interactive data exploration tools, data visualization and analytics platforms) so that test and fleet results are trustworthy, queryable, and actionable • Provide sustaining support after deployment - validate stability, security, and performance under production workloads, and refine understanding of failure characteristics at scale • Set engineering standards for the test software stack - code review, CI, version control, type checking, and documentation - and mentor engineers and technicians • Collaborate across SW, Thermal, Mechanical, EE, Signal Integrity, FPGA, TPM, and Production Engineering teams to integrate optics into systems • Interface with the industry, contribute to the RFI/RFP process, and shape product requirements, test plans, and data sheets Minimum Qualifications • Bachelor's degree in Computer Science, Computer Engineering, relevant technical field, or equivalent practical experience • 8+ years in development roles for optical networking hardware, with a proven track record of taking new products into volume production • Demonstrated experience in designing and building production-quality test software (not just scripts) in Python, including modular, reusable test frameworks • Hands-on experience with high-speed optical and electrical test, test automation, and lab instrumentation • Experience leading optical transceiver NPI programs with vendors and/or ODMs Preferred Qualifications • Experience with version control (Git/Mercurial), large monorepo workflows, and collaborative/distributed software development environments • Familiarity with data center network architecture, fleet health/sustaining concepts, and high-volume manufacturing test flows • Willingness to work hands-on in the lab and to travel to vendor, ODM, and manufacturing sites as needed to support NPI builds • Experience creating or influencing product requirements documents (PRDs), test plans, and data sheets • Expertise in optical test and measurement: BER/FEC, pre-FEC/post-FEC analysis, eye diagrams, TDECQ, OSNR, optical spectrum, and link budgets • Data engineering for test and fleet health: schema design, database/warehouse persistence, dashboards, and statistical analysis of measurement data (e.g., NumPy, pandas, SQL) • Experience with optical integration including InP PICs, silicon-photonic PICs, PIC-IC integration, and 3D optical packaging technologies • Experience driving NPI milestones (EVT/DVT/PVT/MTF), production-readiness reviews, and transferring test infrastructure to contract manufacturers / ODM factory lines (including dual-ODM strategies) • Experience building instrument-control and test-automation frameworks (e.g., SCPI/VISA, PyVISA, vendor APIs) and abstracting heterogeneous instruments behind clean interfaces • Proficiency in Python software engineering: object-oriented design, abstraction layers, type hints, unit/integration testing, code review, and CI/CD discipline • Familiarity with additional languages is useful: C/C++, MATLAB, or Rust • Ability to set technical direction across a multi-quarter NPI program, define scope and priorities when requirements are incomplete, and align cross-functional and external partners (vendors, ODMs, TPM, Production Engineering) • Track record of mentoring engineers, improving engineering practices through code reviews, documentation, and technical standards, and influencing without direct authority • Deep knowledge of pluggable optical transceivers and form factors (QSFP-DD, OSFP, QSFP112) and the CMIS management interface • Experience with advanced modulation formats and direct-detect and coherent systems (e.g., OOK, PAM-4, QPSK, 8-QAM, 16-QAM) and related concepts
