Job description

Work that is reshaping how the world makes and stores heat

You will be working on projects that are reshaping how the world makes and stores heat: repurposing coal plant assets into renewable energy storage, integrating high‑temperature storage with nuclear and SMR projects, replacing fossil boilers with electrified dispatchable steam for oil and gas, cutting fossil dependency in industrial process heat, and converting surplus renewable power into long‑duration thermal storage.

Responsibilities

• Developing heat and mass balances (HMB) for large‑scale thermal systems based on molten salt and thermal oil, typically used for steam generation.
• Performing thermal process calculations: pressure drop, flow and temperature profiles, heat‑exchanger sizing and thermal dimensioning.
• Carrying out general thermal process analyses.
• Developing and maintaining calculation tools in MATLAB/Simulink.
• Ensuring thorough documentation of calculations, methodologies and assumptions.
• Preparing, scheduling, coordinating and monitoring assigned engineering/study tasks, reporting regularly to the project/Study Manager.
• Reviewing engineering documents (specifications, procedures, deliverables) and proposing corrective actions.
• Supporting R&D / EU‑funded projects (RIA, IA) with thermal process inputs and engineering deliverables, including coordination with multicultural teams.
• Interacting with clients and other disciplines to interpret requirements and translate them into technical specifications.
• Monitoring compliance with applicable codes, QA/QC policies and performance standards.

A process engineer grounded in thermal systems

We are looking for someone who combines real depth in thermal/process engineering with a structured, independent way of working. Ideally you bring most of the following:

Qualifications

• Engineering degree (energy, process, mechanical engineering or similar).
• Solid experience in thermodynamics and heat transfer, fluid mechanics, and analysis of complex thermal systems.
• Knowledge of integrated energy systems, concentrated solar power/solar thermal, thermal energy storage and thermodynamic cycles (Rankine, Brayton, etc.).
• Experience with MATLAB/Simulink, preferably including development of calculation tools.
• Familiarity with R&D / EU projects (RIA, IA) is a plus.
• Familiarity with engineering development phases such as Front‑End‑Loading (FEL 0‑3) is a plus.
• Structured way of working, with strong documentation skills.
• Comfortable working independently on technically complex tasks, and coordinating with multidisciplinary, multicultural teams.
• Task management, decision‑making and time‑management skills.
• English level: C1. Danish or Spanish is a plus.

Company Overview

We engineer thermal integration for the energy transition, supporting energy and industrial sectors with electrification, thermal energy storage, steam generation, and the integration of high‑temperature systems. Aalborg CSP is an independent thermal engineering and consulting firm with close to four decades of experience, taking projects from concept to operating plant across five continents.

Team & Work Environment

We are a small team of specialists based in Aalborg (Denmark) and Seville (Spain) who care about changing the way energy is produced today. The hierarchy is flat, the team is multicultural, and our official language is English. You will have visible ownership of your work, report to the project manager and collaborate directly with senior engineers, R&D and clients.

Benefits & Working Conditions

We support flexible or hybrid working. Relocation assistance is not provided for this role.
