Public Procurement Buyer

Success of Engineering Projects mostly relies on key individuals demonstrating Intrapreneurial Leadership, and the best way to develop these skills is through hands-on consulting roles—working alongside established intrapreneurs in international companies, contributing to managing stakeholders' engagement, workflows' reliability, or solutions' sustainability.

Without a reliable procurement process in place, critical infrastructure projects risk delays, budget overruns, and non-compliance with legal frameworks—threatening the success of the entire energy transition effort.

We would therefore welcome you at AETHER to support Intrapreneurial Projects, as a Medior Public Procurement Buyer:

The scope, here, is to manage and secure public procurement processes across strategic categories, ensuring compliance, stakeholder alignment, and timely execution of high-impact acquisitions.

The Key responsibilities expected from our consultant might include:

Support projects through high-quality and detail-oriented execution (provide, accomplish, analyze, develop, define, draft, prepare, document)

• Define the best approach for competitive tendering, propose decision criteria, integrate critical technical, commercial and legal points and risks.
• Participate in drafting market documents (launch, specification / cahier des charges, attribution).
• Draw up the terms of reference (contractual and commercial terms, administrative aspects) in connection with the technical prescriptions.
• Define the selection and award criteria to meet project services' needs.

Support projects with rational and data-driven assessments (identify, monitor, evaluate, measure, verify, control)

• Ensure implementation of contracts and monitor their execution (management and follow-up of amendments, complaints and non-conformities).
• Participate actively in supplier performance management and continuous improvement of the Purchasing Service processes.

Support projects by facilitating communication and reporting between stakeholders (manage, coordinate, ensure, present, liaise, negotiate)

• Manage files in one or more procurement families.
• Accompany multidisciplinary teams and organise kick-off meetings to collect project needs.
• Act as the liaison point between internal stakeholders and suppliers.
• Ensure the progression of reflection in the team and the attainment of expected results.
• Appreciate and manage the variety of markets, interlocutors and situations encountered.
• Work in tandem with the administrative manager of the file from the Purchasing Service according to priorities.
• Analyse and negotiate the terms of offers and contract conditions.
• Present award results to Management.
• Ensure the link with the Legal Service and respect of the public procurement legal framework.
• Immediately manage three procurement files: acquisition of vehicles; training services; training and examination services for driving licences.

The experience we are actively looking for:

• Master's degree education level
• At least 3 years of experience in procurement, ideally within indirect categories mentioned
• Minimum 2 years of experience in public procurement is considered an asset
