Senior Project Controller, Fuel

About this role

Thanks for your interest in Oklo! We are searching for a Sr. Project Controller, Fuel to join our team.

Position Description

We are seeking a disciplined, analytical, and commercially minded Project Controller to support capital project delivery across Oklo’s Fuel business unit and supporting infrastructure.

This role is expected to provide an independent financial perspective within the project team, constructively challenging assumptions and ensuring financial integrity in forecasting, reporting, and commercial decision making.

This role will be a key member of the Fuels project teams and will partner closely with the Project Manager, Project Sponsor and Fuels’ business leaders to ensure rigorous cost control, schedule integration, financial transparency, and performance accountability throughout the project lifecycle.

This role interfaces with the EPC and other vendors, reviewing reporting, participating in regular updates, and constructively challenging cost and progress assumptions.

The Project Controller will work in close coordination with the Capital Cost Management and the Planning and Scheduling team to ensure project-level cost tracking, reporting, and forecasting remain aligned with the project plan, physical progress as well as with established cost frameworks, breakdown structures, and governance standards.

This role reports into the Sr. Director of Project Budgeting and Controls with day-to-day integration within project teams.

Specific responsibilities may include:

• Forecasting and EAC Ownership: Develop and maintain independent cost-to-complete and Estimate at Completion (EAC) positions, ensuring forecasts reflect financial reality and risk exposure. Provide data-informed challenge to assumptions impacting cost and schedule outcomes and clearly articulate forecast deltas, underlying drivers, and financial implications to project and senior leadership.

• Cost Control and Tracking: Provide trusted reporting, trending, and variance analyses of commitments and actual expenditures compared to project budgets.

• Project Performance Assessment: Lead cost and schedule integration to assess project performance, including the financial impacts of schedule changes and drive transparency between progress and cost performance.

• Risk and Performance Management: Identify and quantify cost and schedule risk. Maintain independent, data-informed judgement of project performance and escalate concerns around forecast integrity and compliance. Monitor contingency utilization and change order trends.

• Reporting & Insights: Own monthly project financial reporting packages and executive-ready project narratives. Support the preparation of materials for senior leadership reviews as required.

• Vendor and Contract Performance Oversight: Review and audit contractor and vendor cost reports and validate progress against contractual milestones, physical progress and schedule status. Hold vendors accountable to transparent, timely, and contractually compliant reporting standards and frequency.

• Governance and Framework Alignment: Ensure project-level cost tracking aligns with standardized methodologies and governance frameworks established through partnership with the Capital Cost Management team. Maintain and enforce cost discipline and reporting consistency across project teams.

• Corporate Financial Integration: Act as the primary interface between project financials and accounting to ensure accurate consolidation, alignment, and reporting of project financial data.

Minimum Qualifications:

• 7+ years of progressive project controls experience, including ownership of EAC and independent forecast development within large-scale energy, infrastructure, industrial, or construction sectors

• Experience supporting EPC or construction projects (preferably $100M+ environments)

• Strong knowledge of cost control processes, forecasting, earned value, and schedule integration

• Experience reviewing contractor reporting and managing change control processes

• Strong analytical skills with comfort working in large datasets and financial models

• Proficiency with ERP and project cost systems, with ability to adapt across tools and environments

• Proven ability to work closely with cross-functional project teams

• Clear and concise communication skills

Bonus Qualifications:

• Experience with nuclear or other FOAK energy infrastructure projects

• Familiarity with DOE, NRC, and other regulated capital environments

• Experience with IRA ITC eligibility and compliance tracking.

• Startup or high-growth company experience

Competencies

We are looking for a Sr. Project Controller that is:

• Comfortable operating in constructive tension with project leadership to protect long-term project performance.

• Confident presenting independent project performance positions to senior stakeholders.

• Courageous in raising uncomfortable financial and performance truths early.

• High personal accountability for forecast accuracy and financial transparency.

• Detail-oriented and disciplined in financial analysis

• Comfortable operating in a fast-paced, evolving project environment

• Willing to challenge assumptions constructively

• Collaborative and team-oriented while maintaining independent judgment

• Data-driven and proactive in identifying risks and trends

• Clear and effective in communicating financial insights

Who you are:

A startup person : You aren't driven by titles or hierarchy, and prefer efficiency to excess process. You don't need or expect to have a lot of guidance but you enjoy working in a fast-paced team. If you prefer the culture and feel of a large organization, that is great, but you likely won’t enjoy working with us! There is plenty of important work and plenty of good opportunities with organizations like that.

Motivated : You are self-motivated. You bring an enthusiasm to the team, and imbue a sense of passion that goes beyond clocking in and clocking out. This
