What's it like to work at Masimo?

Strengths in mission impact, innovative products, and HQ amenities are accompanied by a demanding pace, local layoff history, and ongoing corporate change. Together, these dynamics suggest the Irvine office offers meaningful, high‑energy work with solid benefits, while requiring comfort with intensity and integration‑driven shifts.

Key Insight for Candidates

HQ intensity tradeoff: In Irvine—home to headquarters and much of engineering—you get proximity to core teams and onsite amenities, but employees frequently report heavy workloads and long hours, and the site has seen recent layoffs and reorgs. Weigh impact and access against pace and change.

Positive Themes About Masimo

  • Mission & Purpose: Work in Irvine is closely tied to patient‑monitoring technologies used in hospitals, reinforcing a 'patients first' ethos and visible clinical impact. Feedback suggests this mission focus is a clear draw at the headquarters.
  • Benefits & Perks: The Irvine headquarters offers on‑site amenities like a gym, wellness center, and cafe, alongside comprehensive health coverage and a company‑match 401(k). Feedback suggests total rewards are viewed as solid.
  • Innovation & Products: Teams in Irvine are connected to core noninvasive monitoring platforms such as SET pulse oximetry, providing cutting‑edge hardware and software challenges. This product environment attracts people seeking high‑impact med‑tech work.

Considerations About Masimo

  • Workload & Burnout: In Irvine, the pace is often described as demanding, with some teams noting long hours. Feedback suggests this intensity can strain boundaries outside of work.
  • Job Insecurity: Layoffs at the Irvine site, including a WARN‑noted reduction in late 2024/early 2025, have raised concerns about stability. Such actions signal restructuring risk at headquarters.
  • Change Fatigue: Irvine teams have navigated leadership transitions, portfolio shifts, and a pending acquisition while headquarters remains in place. These shifts can drive reorgs and evolving priorities that tax local bandwidth.
