Role: Bioresources and O&M Lead Proposal Engineer
Location Base: Head Office Loughrea, Co. Galway
Salary: Competitive salary
The Role
We are seeking an accomplished and technically authoritative Bioresources and O&M Lead Proposal Engineer to join the central tendering and pre‑construction function. This role will be central to the successful delivery of complex industrial tenders across wastewater treatment, anaerobic digestion, energy recovery and associated operations and maintenance works.
As a senior technical contributor within the tendering team, you will take ownership of the technical development of proposals from early engagement through to submission. You will bring strong process understanding, engineering judgement and strategic insight to shape compliant, buildable and competitive solutions that reflect best practice in industrial treatment and energy projects.
Working closely with estimators, designers, operations teams and supply chain partners, you will ensure that all technical proposals are underpinned by sound engineering principles, a clear understanding of construction and operational risk, and alignment with the commercial strategy.
You will play a key role in interrogating specifications, challenging reference designs, and developing robust methodologies that demonstrate value for money, constructability and long‑term operational performance.
You will contribute to optioneering, feasibility assessments and early‑stage budget development, providing informed technical input to support strategic decision making. The role requires a strong appreciation of brownfield and live operational environments, refurbishment constraints, commissioning and interim operation, and whole‑life considerations.
You will ensure that technical governance and risk management processes are rigorously applied and clearly documented throughout the tender process. As a senior member of the pre‑construction team, you will influence tender strategy, support bid reviews and provide technical leadership to less experienced engineers. This is a pivotal role for a technically credible professional who can operate confidently under pressure, manage multiple concurrent tenders and contribute directly to the successful conversion of complex industrial opportunities.
