Lightmatter is leading the revolution in AI data center infrastructure, enabling the next giant leaps in human progress. The company invented the world’s first 3D-stacked photonics engine, Passage™, capable of connecting thousands to millions of processors at the speed of light in extreme-scale data centers for the most advanced AI and HPC workloads.

Lightmatter raised $400 million in its Series D round, reaching a valuation of $4.4 billion. We will continue to accelerate the development of data center photonics and grow every department at Lightmatter!

Lightmatter is (re)inventing the future of computing with light!

Lightmatter's Supply Chain Operations team designs and executes the complex, global manufacturing networks required to build our world-first photonic engines at scale. We partner seamlessly with critical component vendors and Tier-1 manufacturing partners to deliver a resilient, cost-effective, and rapid flow of cutting-edge hardware.

As an Operations Program Manager, you will serve as the primary operational program owner driving supplier execution, Statement of Work governance, and master build planning across silicon foundries, Tier-1/Tier-2 OSATs, and Contract Manufacturers. Operating with high autonomy, you will bridge internal R&D, Packaging Engineering, Quality, and Commercial teams with external vendor leadership to drive NPI builds through to High-Volume Manufacturing.

In this role, you will immediately take operational ownership of active Passage and/or Guide programs. You will maintain complete control over multi-tier material availability tracking, Clear-To-Build readiness, vendor milestone enforcement, and cross-functional schedule alignment.

Core Responsibilities

• Serve as the senior operational leader owning the complete material development lifecycle from NPI through HVM. You will act as the primary operations counterpart to engineering and quality teams, collaborating directly with external vendors to ensure all hardware materials are realized and available to support the master schedule.
• Drive end-to-end operational execution for assigned electro-optical program lines by aligning customer and internal demand into master build plans spanning silicon foundries, OSATs, and Contract Manufacturers.
• Build and maintain virtual line-item Clear-To-Build (CTB) matrices across multi-tier suppliers. You will track component lead times and drive consigned material staging into OSAT and CM facilities to guarantee unblocked build execution.
• Partner with engineering leads to draft, enforce, and track vendor Statements of Work. You will conduct weekly operational progress reviews, hold suppliers accountable to milestone deliverables, and drive overall vendor execution metrics.
• Actively track and resolve critical-path dependencies that impact external manufacturing, driving internal teams to provide the design freeze sign-offs, ECO cut-ins, and test scripts required by vendor partners to proceed with production.
• Maintain transparent milestone risk logs, material readiness trackers, and build progress dashboards to consistently communicate program status and critical path risks to executive leadership with actionable mitigation plans.
• Own PLM workflows across the product lifecycle, which includes creating and managing Bills of Materials and directly managing the routing and approval of Engineering Change Orders.

Required Qualifications

• Bachelor's degree in Supply Chain, Business Management, Engineering, or a related field, complemented by relevant operational experience.
• 8+ years of progressive experience in Operations Program Management or Partner Operations within high-tech hardware, semiconductors, optical networking, or silicon photonics.
• Proven track record directly managing external manufacturing partners, contract manufacturers, silicon foundries, or OSATs through complex NPI-to-HVM build cycles.
• Advanced expertise constructing multi-tier master schedules, tracking material availability, and enforcing line-item CTB matrices across multi-stage assembly flows.
• Executive presence, influence, and assertiveness necessary to drive both internal engineering teams and external partner program managers to strict milestone dates.
• Hands-on experience executing BOM management, ECO routing, and revision control within PLM systems, alongside working within ERP/MRP environments.

Preferred Qualifications

• A Master’s degree in Supply Chain Management, Industrial Engineering, or a technical discipline is strongly preferred.
• Highly value direct experience managing operational supplier partnerships specifically in electro-optical packaging, silicon photonics, high-speed optical transceivers, or AI compute hardware.
• Desire a deep understanding of multi-tier semiconductor transitions, from wafer sort through advanced packaging to final module assembly.
• Hands-on experience executing BOM management, ECO routing, and revision control within PLM software (e.g., Arena, Agile, Teamcenter, or similar).

We offer competitive compensation. The base salary range for this role determined based on location, experience, educational background, and market data.

Salary Range: total compensation goes beyond base salary, it also includes a new hire equity grant, annual performance-based equity, and other rewards that recognize your impact and contribution.$149,000—$220,000 USD
