Python Developer - Engineering Calculations (B2B cooperation)

B2B cooperation · Python · structural engineering calculations · remote-friendly · start ASAP

MindPal builds custom, AI-powered software, mostly for manufacturing and construction companies. Our developers don't just write code: they understand how much a feature saves or earns for the client and talk to the client's experts directly.

We are looking for a Python developer to cooperate with us on a project for a client in the construction sector. The project turns structural engineering calculations, today kept in Excel, into tested Python code running on a server. Engineers rely on these numbers, so every result has to be right, and stay right after every change.

• Scope of services
• Port structural engineering calculations from Excel spreadsheets into clean, readable Python code.
• Deploy the calculation modules on a server so the client's application can use them.
• Build automated checks (e.g. pytest regression suites) that verify results after every change to the application.
• Compare code results with the original spreadsheets and hand calculations, and flag any discrepancy early.
• Consult assumptions and edge cases directly with the client's engineers, in English.
• Document formulas, units and assumptions so every result can be traced back to its source.
• Requirements
• 1-3 years of commercial experience with Python, or an engineering background with substantial Python projects (e.g. calculation tools or a computational model built for a thesis).
• Comfortable reading structural engineering calculations: loads, internal forces, cross-section checks. A civil, structural or mechanical engineering background is a strong plus.
• Experience turning spreadsheet logic into code, and a habit of checking that the numbers still match.
• A QA mindset: you write automated tests as part of the work, not as an afterthought.
• Meticulous and self-driven: you own the result and say early when something does not add up.
• Good English (B2+) for discussing calculations with engineers.
• Nice to have
• Familiarity with Eurocodes or structural software such as Autodesk Robot Structural Analysis or FEM tools.
• NumPy, pandas, openpyxl or similar libraries.
• FastAPI or Flask, Docker, CI/CD.
• Using AI tools in your workflow, together with a clear way of verifying what they produce.
• What we provide in cooperation
• B2B cooperation, rate: 40-70 PLN net + VAT / hour, depending on experience.
• Remote cooperation, with on-site project coordination in Gliwice possible as needed.
• Cooperation framework agreed with you, taking your availability into account. Some calls with the client's team take place between 16:00 and 19:00 (Polish time) and are scheduled in advance.
• Start as soon as possible.
• Access to technical consultations and knowledge sharing with experienced developers and the client's engineers.
• Direct contact with domain experts: you see how your code is used and what it is worth to the client.
• Additional cooperation options, such as access to selected partner services, if agreed separately.
• How we cooperate

We care about Ownership, Results, Discipline, Transparency, Speed, Craftsmanship and Partnership with our clients (mindpal.co/about-us). In this project that means tests written every day, problems reported early, and calculations you are ready to sign.

Recruitment process

• Short call with People Operations (15-20 min): formalities, English, availability.
• Technical conversation (45-60 min), including a short practical task.
• Business and values conversation (20-30 min): how you approach problems and results.
