Job description

Join DayOne – Shaping the Future of Data Infrastructure

DayOne is a global leader in the development and operation of high-performance data centers. As one of the fastest-growing companies in the industry, we’ve built a robust presence across Asia and Europe — and we’re just getting started.

As we expand into new international markets, we’re looking for talented, driven individuals to join us on this exciting journey. This is more than a job — it’s an opportunity to be a key contributor to our dynamic team and help shape the future of global data infrastructure.

If you’re passionate about innovation, technology, and growth, we invite you to be part of DayOne’s next chapter.

About DayOne
DayOne builds and operates hyperscale data centers across nine markets in APAC and Europe. We raised US$4.5B in Series C funding and are in active build across the region. Johor is where DayOne’s Malaysian operations are concentrated, at the heart of the SIJORI corridor connecting Singapore, Johor, and Batam.

In 2026, DayOne committed RM28+ billion to Malaysia and secured a landmark partnership with TNB for over 1GW of renewable energy. Functions based here work close to live campuses, which means the work connects directly to the infrastructure it supports rather than sitting at a distance from it.

About the Role
You’ll own invoice issuance and collection follow-up for DayOne’s billing operations, working closely with Sales, Operations, Project teams, and customers to keep billing accurate and disputes resolved on time.

Billing and Collection Operations

• Issue invoices based on validated charges, coordinating with relevant departments to confirm billable items.

• Ensure timely, accurate billing that protects cash flow and DSO.

• Follow up on overdue accounts and manage payment collection through to resolution.

• Handle customer communication on invoice status, payment queries, and adjustments.

• Record collection activity and prepare status reports for management.

Dispute Resolution

• Handle billing disputes at first point of contact; elevate unresolved or recurring disputes to the Billing Center Manager or AR Analyst for root-cause review.

• Coordinate with Sales, Operations, and Project teams to resolve disputes and prevent recurrence.

Process and Compliance

• Maintain AR records in line with internal controls and audit requirements.

• Flag recurring billing issues and recommend process fixes.

• Support month-end closing and reporting.

Requirements

• 1 to 2 years of experience in billing, AR, collections, or finance operations.

• Diploma in Finance, Accounting, or a related field.

• Familiarity with AR systems and SAP is preferred.

• Experience with billing disputes and escalation is an advantage.

• Proficient in Excel and standard reporting tools.

• Escalates aging accounts through the right channel rather than letting them sit.

• Manages multiple billing cycles and deadlines without losing accuracy.

• Keeps disputes moving toward resolution through clear communication with internal teams and customers.

Nice to Have

• Prior experience in a data center or large corporate billing environment.

• Exposure to automation tools within AR or billing systems.

Why DayOne?
DayOne is scaling fast across nine markets, and billing accuracy at this stage directly protects cash flow for a company deploying capital at pace. You’ll work closely with Sales, Operations, and Project teams on live client accounts, with clear ownership of your portfolio.

DayOne is proud to be an equal opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees.

If you’re ready to grow with one of the fastest-moving companies in the data center industry, and be part of our global journey.
