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.
