R&D Engineer (Software Architecture & Automation)

Rotselaar, BEFull-timePosted Apr 29, 2026

Job description

With this innovative and distruptive technology company, we aren't just making parts; we are solving the most physical bottleneck in the AI revolution: Heat. While traditional data center cooling is reaching its physical limits, we’ve developed ultra-performant Smartfins technology using proprietary generative algorithms.

We are a lean, fast-moving startup bridging the gap between high-level software intelligence and massive-scale hardware manufacturing. If you believe that a design isn't real until it has been stressed, measured, and validated in the lab, you belong here. The Role As our Software & Automation Engineer, you are the Architect of the R&D Factory.

You won't just "automate tasks"; you will design the digital nervous system that connects our core physics solvers to our business operations. Your mission is to build a "self-driving" workflow where code, simulation, and hardware design move in a seamless, automated loop. This is a high-impact role for a "Builder" who can translate raw technical Proof of Concepts (Po.

Cs) into robust, production-grade software.

Key Responsibilities

Take raw engineering concepts and "Smartfins" prototypes and turn them into functional, high-performance code in Python and C++ .Architect the Workflow: Design and maintain the middleware and custom API-driven workflows (Jira, Slack, Autodesk, AWS, internal DBs) that keep our hardware and software teams in perfect sync.

Build the "Digital Nervous System": Develop modular, OOP-based frameworks in Python and C++ that automate everything from simulation triggers to software testing. Deploy Intelligent Automation: Integrate LLMs and AI-driven agents into our task management systems to turn raw thermal data into actionable engineering insights.

Own the Pipeline: Maintain and evolve our CI/CD pipelines and automated testing suites, ensuring our R&D team can ship "physics-heavy" code with total confidence. What You Bring The Essentials: Educational Foundation: An MSc in Computer Science, Software Engineering, or a related field with a strong mathematical lean.

Polyglot Developer: Deep mastery of Python and a strong working knowledge of C++. You understand when to use the flexibility of the former and the performance of the latter. Architectural Rigor: A strong grasp of SOLID principles and Clean Architecture; you write code that is modular, readable, and built for a high-growth production environment.

Physics Affinity: An active interest or background in heat transfer and thermodynamics. You don't need to be a thermal engineer, but you must speak or be willing to learn the language of "Conjugate Heat Transfer. The "Builder" Spirit: You thrive on taking a "half-baked" technical idea and engineering it into a robust, working Proof of Concept.

The "Extra Mile": Experience with CI/CD tools and building robust automated testing frameworks. Experience with AWS/Microsoft Azure/GCP and containerization (Docker/Kubernetes) Hands-on experience implementing LLM-based tools or agents in a production environment. Experience with API-first design and connecting disparate enterprise platforms.

Familiarity with CFD frameworks or CAD automation. Why Join Us? Design at the Inflection Point: You are joining at the exact moment we are scaling our internal "factory. " You will have a blank canvas to build the systems you've always wanted. No Red Tape: We move at the speed of the hardware we cool. If you have a better way to automate a process, you own the implementation from day one.

High-Visibility Impact: Your code will be the "glue" that allows our thermal breakthroughs to reach global data centers faster. The Culture: We are a lean team of elite engineers who value "Clean Code" as much as "Deep Physics.
