Business Development Manager – Water Infrastructure

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 seven markets in APAC and Europe. We raised US$4.5B in Series C funding, and we’re building the internal functions to match that scale. Most of what you’ll work on here doesn’t have a template yet. The processes, systems and ways of working still need to be built by the people in these roles.

About the Role

We are looking for a Business Development Manager specialising in water infrastructure and treatment to support our data center developments in Batam.

You will lead the development of reliable, sustainable and commercially viable water solutions for two potential data center sites, while enhancing water delivery for our existing Kabil facility. You will work closely with SPAM, water authorities, industrial park operators, government bodies, EPC contractors and other infrastructure partners.

This is a strategic, stakeholder-facing role combining business development, commercial negotiation, infrastructure planning and project coordination. While a strong understanding of water infrastructure and treatment systems is essential, this is not a pure engineering position.

What You’ll Do

Build the Water Strategy

• Develop and execute water-supply strategies for DayOne’s existing and potential data center sites in Batam.

• Lead water-readiness planning for two potential development sites.

• Assess water availability, capacity, quality, reliability, redundancy, treatment requirements, infrastructure constraints, costs and delivery timelines.

• Identify opportunities to improve water capacity, quality, reliability and delivery for the existing Kabil facility.

• Evaluate municipal, industrial park, treated-water, recycled-water and other alternative supply solutions.

• Prepare commercial recommendations and business cases to support site selection, investment and development decisions.

Engage and Influence

• Lead engagement and negotiations with SPAM, local water authorities, industrial park operators, government bodies and infrastructure providers.

• Build and maintain relationships with EPC contractors, consultants, treatment-plant operators and strategic partners.

• Coordinate water-supply applications, feasibility assessments, technical submissions, approvals, agreements and relevant permits.

• Represent DayOne in discussions involving water capacity, quality, treatment, infrastructure development and commercial terms.

• Monitor regulatory, tariff, environmental and infrastructure developments that may affect DayOne’s projects.

Develop Water-Treatment Solutions

• Support the development of large-scale water-treatment, wastewater-treatment, storage and distribution solutions.

• Coordinate feasibility studies and technical assessments for new or upgraded water infrastructure.

• Evaluate treatment technologies and delivery models based on capacity, water quality, cost, sustainability and operational requirements.

• Support the selection and management of EPC contractors, consultants, treatment-plant operators and other delivery partners.

• Identify opportunities involving water efficiency, recycling and sustainable water management.

Deliver Across Teams

• Work closely with Development, Engineering, Construction, Operations, Finance, Legal and Commercial teams.

• Translate technical water requirements into clear commercial strategies and management recommendations.

• Coordinate due diligence, feasibility studies, infrastructure assessments and implementation plans.

• Track milestones, budgets, risks, dependencies and stakeholder commitments.

• Support commercial negotiations and contract development with water providers and project partners.

• Escalate issues that may affect project timelines or water readiness.

Requirements

• Minimum 8 years of relevant experience in business development, project development, water utilities, environmental infrastructure or resource planning.

• At least 5 years of direct experience in water supply, large-scale water-treatment plants, wastewater treatment, industrial water infrastructure or water-distribution systems.

• Demonstrated experience delivering or supporting water-infrastructure projects in Indonesia.

• Experience working with SPAM, local water authorities, industrial parks, EPC contractors or major infrastructure providers.

• Practical knowledge of water-capacity planning, quality requirements, treatment systems, utility agreements, permitting and project-delivery processes.

• Experience supporting major water-treatment projects for industrial parks, manufacturing facilities or other large-scale developments.

• Strong commercial judgement and the ability to evaluate cost, risk, schedule and long-term project viability.

• Strong communication, negotiation, presentation and stakeholder-management skills.

• Ability to translate technical information into clear business recommendations.

• Ability to work effectively across technical, commercial, financial, legal and operational teams.

• Professional proficiency in Bahasa Indonesia and English.

• Willingness to be based in Batam and travel as required.

Good to Have

• Data center experience in Indonesia.

• Experience developing water solutions for large industrial or mission-critical facilities.

• Experience working with EPC contractors on major water-treatment projects.

• Knowledge of recycled water, wastewater treatment and sustainable water-management solutions.

• Existing relationships with SPAM, Batam-based authorities, industrial park operators or water-infrastructure providers.

• Bachelor’s degree in civil, environmental or chemical engineering, infrastructure, business, finance or a related discipline.

Why DayOne?

If you’ve spent your career executing inside a function someone else built, this is a different kind of job. DayOne is at the stage where the people joining now get to define how things are done—not inherit a system and maintain it. That’s genuinely rare at a company operating at this scale.

The work is complex, the pace is real, and the decisions you make will still be visible five years from now. You will play a key role in developing reliable and sustainable water infrastructure for Indonesia’s growing digital economy.

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