Type: Full-Time
Location: Remote /Hybrid - site visitsrequired(Canadian nuclear sites)
Sector: Nuclear/Decommissioning / Radioactive Waste Management / Environmental Remediation

About us:

Since 2011Dokainish& Company has delivered project controls and project management consultancy services to owners and developers across North America and the Middle East. Our work spans capital construction programs commercial office towers institutional facilities mission-critical infrastructure and corporate campus developments where our consultants are embedded directly with owner teams to protect schedule cost and delivery outcomes.

The Opportunity:

Dokainish& Company is seeking a Senior Estimator to join a high-performing program controls team supporting a major long-duration nuclear decommissioning and radioactive waste management program. This is a technically demanding high-visibility role in which the incumbent will own the end-to-end development of project cost estimates and supporting documentation across a complex multi-project portfolio spanning reactor decommissioning radioactive waste facility operations environmental remediation and fuel processing programs.

Prior hands-on estimating experience on nuclear decommissioning projects or within licensed nuclear facilities is strongly preferred. Candidates with direct exposure to nuclear facility environment including decommissioning waste management remediation of contaminated nuclear sites or active nuclear plant maintenance and modifications will be given strong preference in the selection process.

The successful candidate will bring deep estimating craft not just process familiarity and will be expected to build defend and stand behind their estimates throughout client review cycles. This is a builder role not a reviewer role.

We are hiring for a full-time permanent role. That said if you are an exceptional candidate seeking a fixed-term or contract engagement we encourage you to apply we are open to discussing alternative arrangements for the right person.

Key Responsibilities:

• Develop project-level baseline cost estimates (AACE Class 35) across a diverse portfolio of nuclear decommissioning waste management and remediation projects.

• Produce comprehensive Bases of Estimate (BOE) for each project including methodology narrativesource data escalation rationale key assumptions exclusions and stated accuracy range.

• Apply parametric analogous and bottom-up estimating methodologies; select theappropriate approachbased on available information and document the rationale explicitly.

• Develop time-phased cost profiles integrated with project schedules; collaborate with senior schedulers on cost loading resource histograms and S-curve generation.

• Provide cost uncertainty inputs (P10/P50/P90 distributions key cost drivers) to the project risk and quantitative risk analysis process.

• Establish and apply consistent estimating norms and unit rates scaled to project complexity and information maturity across the portfolio.

• Support program-level planning deliverables: resource allocation plans escalation profiles and multi-year cost projections.

• Respond to queries onestimatebasis andmethodologywith traceable well-documented backup within defined timelines.

Qualifications & Requirements:

• Minimum 10 years of capital project estimating experience;significant experiencein nuclear decommissioning radioactive waste management environmental remediation of nuclear-contaminated sites or capital projects within licensed nuclear facilities (CANDU research reactors fuel processing isotope production or equivalent) is strongly preferred.

• Demonstrated experience preparing estimates across AACE Class 15 on projects of significant scale and complexity.

• Strong BOE authorshiptrack record document samples will be requested during the interview process.

• Experience in multi-project program environments with concurrent estimate workloads.

• AACE membership in good standing; CCP CEP or PSP designation preferred.

• University degree in Engineering Construction Management Applied Sciences or a related field; equivalent combinations of technical certification anddemonstratedexperience will be considered.

WHAT SETS THE RIGHT CANDIDATE APART

Beyond the required qualifications the candidates who will stand out in this process are those who candemonstrate:

• A track recordof nuclear decommissioning or nuclear facility estimating as the primary work not supporting or incidental exposure. This includes reactor D&D interim and long-term waste storage facility construction radioactive waste characterization and treatment facilities nuclear fuel processing isotope facility decommissioning or environmental remediation of nuclear-contaminated sites.

• BOE authorship at a standard that holds up under independent technical review. Candidates should be able to walk through their document structure from memory and articulate what reviewers will challenge.

• Estimating across multiple simultaneous projects production discipline not just depth on one large assignment.

• Experience in Canadian nuclear is a strong differentiator.

• Comfortoperatingin a structured milestone-driven programcontrolsframework alongside schedulers risk analysts and program managers.
