Senior People Operations Manager

Senra Systems•Cypress, CA

3h•$125,000 - $160,000•Onsite

About The Position

At Senra Systems, we believe that the future of manufacturing lies not in automation, but in configuration. We supercharge electrical wire harness manufacturing through software configuration, transforming skilled assembly tasks into high-throughput production lines. We enable customers to design what they want, when they want it and deliver harness builds at record-breaking speed. Role Overview: As Senior People Operations Manager, you will play a key role in evolving the People Operations and compliance foundation that enables Senra Systems to scale safely, efficiently, and sustainably across multiple sites. As a Series A company growing toward Series B, this role sits at the center of that growth, helping ensure our People systems keep pace as we double headcount and increase operational complexity. You are the day-to-day execution owner for People Operations at our Cypress facility, partnering closely with the Head of People on strategy and employee relations while serving as the internal expert on compliance, systems, and operational delivery. This role requires strong judgment, discretion, and comfort with ambiguity. You’ll be someone people trust with sensitive information and turn to for guidance, while helping build clear, reliable People systems that support a healthy, growing company.

Experience supporting a predominantly hourly, production-based workforce.
Comfort operating in high-growth, early-stage environments (Series A–B or similar) where systems are still being built and priorities shift as the company scales.
Curiosity about People Ops best practices and market trends, with a habit of bringing in new ideas, tools, and approaches to improve how the function runs.
A track record of rolling out new People processes or policies and driving real adoption across managers and teams.
Strong working knowledge of CA employment law, including leave administration and wage and hour compliance.
Proven ability to operate with high autonomy and sound judgment in ambiguous situations.
A builder’s mindset, with experience creating clear, scalable processes and documentation.
Strong attention to detail and pride in getting things right.
Comfort moving between hands-on execution and system-level thinking as the company grows.

Be the go-to People presence for our Cypress facility, with a consistent on-site presence and strong relationships across the floor.
Partner closely with Manufacturing leaders to balance compliance, speed, and real-world practicality.

Keep Senra compliant with CA employment laws (wage and hour, LOA, ACA, OSHA, EEO-1, personnel files) and maintain our compliance calendar.
Run internal audits (payroll, timekeeping, LOA, I-9s, contractor classification) and resolve gaps with the Head of People.
Turn legal and regulatory requirements into clear, usable processes that work in a production environment.
Support additional People Operations initiatives and projects as needed to meet the demands of the business.
Keep our HR systems clean, accurate, and trusted through regular audits and data hygiene.

Partner with Sequoia on benefits administration, renewals, and issue resolution.
Own LOA tracking and coordination across CFRA, FMLA, PFL, SDI, and company supplemental benefits.
Act as the escalation point for complex benefits or leave scenarios.
Deliver a compliant, well-run onboarding and offboarding experience (I-9s, ITAR, COBRA) that sets people up for success from day one through exit.
Work closely with IT, Facilities, and Operations to make cross-functional handoffs smooth and predictable.
Make sure every employee lifecycle change is handled accurately, on time, and with care.
