Technical Program Management Intern at Lightmatter

Technical PM intern at a $4.4B AI photonic computing unicorn. Defining product lifecycle milestones, authoring validation criteria, and building documentation systems for a 300-person engineering org shipping AI data center hardware.

task 01 · product lifecycle

Defining product lifecycle milestones

The core project was creating a program playbook: a structured framework for how programs start, run, and close at Lightmatter. This required interviewing team leads across engineering and product to understand what milestones actually mattered, where handoffs broke down, and what information program managers needed at each stage but were not getting.

The output: 55+ product lifecycle milestones defined across the full org, covering PRD commitment, gap and risk analysis, and budget allocation. The milestone structure was designed to work across both hardware and software teams, which operate on fundamentally different timelines and iterate differently.

Hardware locks decisions early. Software ships continuously. The playbook had to accommodate both without creating a process so rigid it slowed either down.

Authoring engineering validation criteria

Authored 40+ validation criteria for engineering and production tests across Lightmatter's hardware systems. Each criterion mapped to a market standard, with FIT (Failure in Time) evaluations calculated to verify reliability thresholds required for large-scale AI data center deployment.

The validation framework gave engineering teams a clear pass/fail definition for each test, removing ambiguity that had previously stalled sign-off and delayed deployment timelines.

task 03 · documentation pipeline

Building a documentation pipeline

Program and product managers at Lightmatter maintained documentation manually, a process that introduced version drift, inconsistency, and significant update overhead across 30+ PMs. The solution was to treat documentation like code: a CI/CD pipeline built via GitHub Actions that automated documentation generation, validation, and publishing on every commit.

The pipeline reduced update cycle time by 65%. Credentials were secured via GitHub Secrets. Test suites that previously took 8 minutes to run were refactored to complete in 3 minutes, reducing iteration friction for the full PM team.

Production Docs

Static, signed-off, milestone-linked. The authoritative record that follows each program through its full lifecycle.

Working Docs

Dynamic, linked to live Google Drives, organized by functional area. Landing pages designed to be non-prescriptive. Teams adopt the structure at their own pace.

From the team

"Katherine is a self-starter who came onboard with a strong desire to influence the way we manage programs. By the end of the internship, she had aligned our team and engineering stakeholders on the list of reference milestones for future programs at Lightmatter. Her ability to ask insightful questions and engage in meaningful conversations makes her a fantastic team member. She takes ownership of her work, consistently delivers high-quality results, and isn't afraid to seek out new challenges."

"Katherine proved to be an invaluable intern with Lightmatter's TPM team, quickly making a significant impact by streamlining our product lifecycle. Her strong eagerness to learn and high level of drive were consistently evident. I was particularly impressed by her deliberate approach to career development. Katherine's proactive nature and effortless ability to connect with people allowed her to efficiently advance her work. Any team would be fortunate to have her leading their programs."
