About the role

Writer is building a world-class people function, and we're looking for a people operations manager who brings both depth and range. This is a role for someone who thinks in systems, operates with autonomy, and genuinely loves the craft of operations — from the strategic to the hands-on.

You're not just executing processes; you're designing them. You approach people programs the way an engineer approaches a product: with curiosity, rigor, and a bias toward scalability. You can own a project end-to-end, navigate ambiguity without hand-holding, and still show up as a collaborative, trusted partner to everyone around you.

This role sits at the center of our people team and touches everything — lifecycle, compliance, systems, analytics, and experience. You'll help us build the infrastructure that scales with us as we grow.

What you’ll do

• Lead and continuously improve all stages of the employee lifecycle: pre-boarding, onboarding, role changes, and offboarding.

• Define, document, and improve people operations processes and best practices.

• Lead people team initiatives from scoping through execution: company events, employee experience programs, policy rollouts, system implementations, and organizational change management.

• Lead and implement automation efforts using WRITER's own AI platform — identifying opportunities to streamline processes and connect our people tools into more efficient workflows.

• Administer and optimize our HRIS and people tooling. Build and maintain operational dashboards to surface key people metrics

• Manage compliance posture across federal, state, and local employment regulations.

• Lead internal audits, maintain accurate employee records, update our employee handbook, and develop training and communications to keep the organization aligned with legal and regulatory standards.

• Partner with employees and legal counsel to manage visa processing and global mobility cases with accuracy and care.

• Navigate sensitive employee relations matters with sound judgment, empathy, and professionalism.

• Work closely with recruiting, finance, legal, IT, and compliance to design efficient cross-functional workflows.

️ What you need

• 7+ years of experience in human resources, people operations, or a closely related operational role — ideally at a high-growth technology company

• Demonstrated ability to design and implement processes from scratch, not just inherit and maintain them

• Strong project management skills: you're organized, deadline-driven, and comfortable managing multiple workstreams simultaneously

• A systems-thinking mindset — you naturally map workflows, look for automation opportunities, and build for scale

• Experience with people analytics: building dashboards, tracking trends, and using data to inform strategy

• Hands-on experience with HRIS platforms and a track record of improving HR operational systems

• Deep knowledge of employment law and HR compliance across federal, state, and local regulations

• High emotional and social intelligence — you build genuine relationships across all levels and functions

• Excellent written and verbal communication skills; you're a clear, confident presenter

Even better if…

• SHRM-CP, SHRM-SCP, or PHR/SPHR certification

• Track record of using AI and automation tools to significantly improve people ops workflow efficiency and employee experience.

• Experience building databases or improving HR operational infrastructure

Benefits & perks (US Full-time employees)

• Generous PTO, plus company holidays

• Medical, dental, and vision coverage for you and your family

• Paid parental leave for all parents (16 weeks)

• Fertility and family planning support

• Early-detection cancer testing through Galleri

• Flexible spending account and dependent FSA options
