Senior HRIS Specialist

Company Overview

Allen Control Systems (ACS) is a cutting-edge defense startup founded by two former Navy electrical engineers with a proven track record in robotics and software. We are developing an autonomous gun turret using advanced computer vision and control systems to precisely detect, track, and neutralize enemy drones.

With an engineering-first culture, ACS values technical excellence and innovation. Backed by our founders’ successful exits from two previous ventures acquired for a combined $180M in 2022, we are committed to ensuring that the groundbreaking technologies we develop will have a real-world impact.

• Manage Rippling integrations with Ashby, time tracking, expense management, benefits vendors, and other external systems; develop automated data workflows to reduce manual entry; monitor integration health and troubleshoot sync issues.
• Design and build Rippling reports and dashboards for leadership and managers covering headcount, turnover, hiring pipeline, compensation, and org structure; support strategic HR planning with data analysis and present insights and recommendations to leadership.
• Ensure Rippling configurations meet compliance requirements (HIPAA, ADA, I-9, data privacy); maintain data security and access controls; support audit documentation; respond to employee and manager Rippling questions and provide ongoing training and support to all users.

• Excellent organizational, communication, and problem-solving skills; ability to maintain confidentiality and handle sensitive employee data with professionalism.
