Total Rewards & People Operations Specialist

Miami, Florida, United States

ON.energy is building the power infrastructure that makes the AI era possible. As AI demand surges past what the grid and traditional data centers can support, ON.energy provides a new class of power technology proven at gigawatt scale and trusted by the world’s leading cloud and AI companies. Our systems are already deployed across 2.5 GW of hyper-scale campuses, validated by top U.S. national labs, and certified for grid-safe operation by major utilities. With real products in the field, we’re scaling faster than the grid can, transforming power from a bottleneck into a competitive advantage for the companies building the future.

ON.energy are seeking a Total Rewards & People Operations Specialist to own the programs and processes that keep our compensation, benefits, and people operations running accurately and at scale. Sitting within People & Culture, you will administer total rewards programs and the systems and data behind them, working independently to solve problems that are difficult and sometimes complex. You will manage projects and processes end to end, and partner closely with payroll, finance, and people business partners across our U.S. and international teams. You will also coach and review the work of more junior analysts to deliver an accurate, consistent experience as we grow. 

Key Responsibilities 

Total Rewards 

  • Administer compensation programs end to end — including the annual merit, bonus, and equity cycles — and prepare clear, accurate inputs and analysis for review. 

  • Maintain salary structures, job architecture, and the job catalog; map roles to the leveling framework and recommend leveling and offer decisions using market data. 

  • Run market benchmarking using compensation surveys (e.g., Aon, Mercer, Carta) and translate findings into actionable range and pay recommendations. 

  • Administer benefits programs — medical, dental, vision, 401(k), and leave — including open enrollment, vendor coordination, and resolving employee questions. 

  • Monitor and support compliance with applicable regulations (e.g., FLSA, ACA, ERISA, and pay-transparency requirements), including multi-state and international considerations. 

People Operations 

  • Own HRIS data integrity, workflows, and reporting; process employee lifecycle transactions across onboarding, job and pay changes, and offboarding. 
  • Partner with payroll to ensure accurate, timely, and compliant pay across U.S. and Mexico-based teams, conducting reconciliations and resolving discrepancies at the root cause. 
  • Develop and document People Operations standard operating procedures, controls, and self-service resources to scale a consistent employee experience. 
  • Produce people analytics and reporting — headcount, turnover, compa-ratios, and program metrics — to inform decisions and support audits. 
  • Coach and review the work of more junior analysts, and serve as a subject-matter resource and escalation point for complex compensation, benefits, and operations questions. 

What You’ll Bring 

  • 5–8 years of progressive experience in total rewards, compensation and benefits, and/or HR / People Operations. 
  • Bachelor’s degree in Human Resources, Business, Finance, or a related field — or equivalent practical experience. 
  • Hands-on HRIS experience (e.g., Workday, HiBob, BambooHR, ADP) and advanced Microsoft Excel / Google Sheets skills. 
  • Working knowledge of compensation benchmarking and survey methodology, job architecture, and leveling frameworks. 
  • Familiarity with U.S. employment and benefits regulations; exposure to multi-country programs (U.S. plus Mexico / LatAm) is a strong plus. 
  • Proven ability to manage multiple workstreams independently, meet deadlines, and communicate effectively across all levels of an organization. 
  • High attention to detail and sound judgment handling confidential and sensitive data. 
  • Relevant certifications (e.g., CCP, CEBS, PHR/SHRM-CP) are a plus. 

For US-based roles - What you’ll get:

  • Competitive salary + annual performance-based bonus eligibility
  • Medical, dental, and vision insurance
  • 401(k) with company match
  • Paid time off and company holidays 

For Mexico-based roles - What you’ll get:

  • Competitive salary + annual performance bonus eligibility
  • Christmas Bonus (Aguinaldo): 30 days
  • Major medical expenses and life insurance
  • Paid time off and holidays (per local policy)

For all roles:

  • Professional development and growth opportunities
  • Opportunity to grow with a mission-driven team shaping the future of clean energy
  • Equal Opportunity: ON.energy is committed to equal employment opportunity and to maintaining a work environment free of harassment, discrimination, or retaliation.
  • Accommodations: If you need an accommodation during the application process, email recruitment@onenergystorage.com

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
