People Operations Coordinator

About Schemata

At Schemata, we are transforming the $400 B virtual‑training and simulation market by fusing 3D computer vision, neural rendering and large multimodal models inside highly regulated industries. Our platform delivers photorealistic, intelligent 3D experiences, demanding robust spatial reasoning, high‑performance data pipelines and seamless integration between traditional graphics and AI‑driven perception.

About the Role

We are hiring our first dedicated People Operations Coordinator to take ownership of the back-of-house work that keeps the company running. This is the person who makes sure people get paid correctly, new hires start smoothly, the founders' time is protected, and the small operational fires get put out before they spread.

This is a broad, hands-on generalist role, not a narrow HR specialist seat. You will spend part of your week on HR and compliance, part on recruiting, part supporting the executive team directly, and part on everything else that a growing 15-person company needs but has not yet built. If you like variety, take pride in running a tight ship, and want real ownership at an early-stage defense tech company, this is a rare opportunity to build the people and operations function from the ground up.

Core Responsibilities

People operations and HR

1. Run day-to-day HR administration: onboarding and offboarding, employee records, PTO tracking, and benefits enrollment.

2. Administer payroll and benefits through our existing systems (Rippling, Human Interest 401(k)), and serve as the first point of contact for employee questions.

3. Maintain and improve HR policies, the employee handbook, and compliance across a multi-state workforce.

4. Coordinate performance review cycles, feedback surveys, and other people programs as we scale.

5. Keep us compliant with federal and state employment requirements, and flag issues to the founding team early.

Recruiting

1. Assist team managers with hiring: job postings, sourcing support, scheduling interviews, candidate communication, and moving people through the pipeline.

2. Manage offer letters, background checks, and the handoff into onboarding.

3. Help build a repeatable, professional hiring process as headcount grows.

Executive and administrative support

1. Provide direct support to the executive team, including calendar management, travel booking, expense processing, and meeting coordination.

2. Prepare and organize materials, track action items, and keep the leadership team on schedule.

3. Handle sensitive information with discretion and sound judgment.

Internal events and culture

1. Plan and run team events and gatherings across our DC and SF offices.

General operations

1. Manage office logistics, vendors, supplies, and facilities coordination.

2. Own miscellaneous back-of-house tasks and projects.

3. Build the systems and documentation that let us stay organized as we grow.
