Senior Estimator - Nuclear Decommissioning & Environmental Remediation Type: Full-Time
Location: Remote / Hybrid - site visits required (Canadian nuclear sites)
Sector: Nuclear / Decommissioning / Radioactive Waste Management / Environmental Remediation About us:
Since 2011, Dokainish & 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.
We specialize in Project Controls, Project Management, Quantitative Risk Analysis, Estimating, and Enterprise Reporting for major capital projects.
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:
Produce comprehensive Bases of Estimate (BOE) for each project, including methodology narrative, source data, escalation rationale, key assumptions, exclusions, and stated accuracy range.
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 on estimate basis and methodology with traceable, well-documented backup within defined timelines.
Qualifications & Requirements:Minimum 10 years of capital project estimating experience; significant experience in 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.
University degree in Engineering, Construction Management, Applied Sciences, or a related field; equivalent combinations of technical certification and demonstrated experience will be considered.
APPLICATION REQUIREMENT - BOE Sample: A Basis of Estimate (BOE) document sample must be submitted with your application. Please remove/redact any confidential client or project information prior to submission. Applications without a BOE sample will not be considered. WHAT SETS THE RIGHT CANDIDATE APART
Beyond the required qualifications, the candidates who will stand out in this process are those who can demonstrate:
A track record of 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.
Comfort operating in a structured, milestone-driven program controls framework alongside schedulers, risk analysts, and program managers.
