Payroll Associate

Who we are

Atoms is building the machines that power the next era of progress.

Over the last decade, software has transformed the digital world. But the physical world, where food is made, minerals are mined, goods are moved, and industries are run, remains far less intelligent, far less efficient, and far more constrained. We’re changing that.

Atoms builds Physical AI— real-world robots for the industries that move civilization forward, starting with food, mining, and transport. Our systems are designed to understand, predict, and control the real world with precision, turning complex physical operations into something more reliable, more scalable, and more productive.

This work requires more than robotics. It requires deep integration across hardware, software, AI, operations, manufacturing, and real estate. We don’t just build machines in a lab. We deploy them into real environments, operate them, learn from them, and improve them until they work at scale.

We are roboticists, engineers, operators, and builders. We believe the next great technology companies will not only transform information, but the physical systems that shape everyday life.

If you want to work on hard problems with real-world impact, join us.

What you’ll do

• Execute payroll processes, including the calculation of gross/net pay, overtime, commissions, bonuses, and deferred compensation.
• Manage the full "hire-to-retire" lifecycle in Workday, handling everything from onboarding and offboarding to salary adjustments and leave of absence.
• Stay ahead of local payroll legislation to ensure all tax withholdings, mandatory deductions, and payroll liabilities are strictly compliant.
• Perform regular audits of payroll records and reconcile general ledger entries to ensure financial accuracy.
• Act as the primary point of contact for employees and supervisors, resolving complex payroll inquiries with clarity and empathy.
• Proactively identify inaccuracies or missing information in our people data and implement reporting improvements.

What we’re looking for

• Understanding of US payroll taxes, labor laws, and statutory deductions is a huge plus.
• 3+ years of experience in payroll administration, preferably within a multinational or high-growth tech environment.
• Advanced hands-on experience with Workday (specifically the Payroll and HCM modules) is highly preferred.
• Full professional proficiency in English (B2 or higher). You will be communicating daily with global stakeholders, writing reports, and navigating systems entirely in English.
• Strong Excel skills and the ability to reconcile complex data sets without breaking a sweat.

Why join us

At Atoms, you’ll work on one of the defining challenges of our time—bringing automation into the physical world to drive real, lasting impact. We exist to uncover valuable unknown truths and turn them into progress, which means constantly pushing beyond what’s known and building what doesn’t yet exist. The work is ambitious and often challenging, but it’s grounded in a shared sense of purpose and a team committed to seeing it through together. Our work only matters if it serves others, and we know that meaningful progress depends on the trust of the people we serve and the strength of our team—so we invest in both, creating an environment where you can do your best work and grow.

What else you need to know

This role is based in our Bogotá office. Atoms is a company driven by invention and continuous change - we are constantly reimagining our industries, building new products, and refining how we operate. We do our best work together. That’s why all of our office-based teams work onsite, five days a week.
