光学工程师，RTP，测试软件架构与光学NPI

Meta（Meta Platforms）岗位：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

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 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

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

Meta builds technologies that help people connect, find communities, and grow businesses.

When Facebook launched in 2004, it changed the way people connect.

Apps like Messenger, Instagram and WhatsApp further empowered billions around the world.

Now, Meta is moving beyond 2D screens toward immersive experiences like augmented and virtual reality to help build the next evolution in social technology.

People who choose to build their careers by building with us at Meta help shape a future that will take us beyond what digital connection makes possible today—beyond the constraints of screens, the limits of distance, and even the rules of physics.
