About the technology
What Fortran is
Fortran is a long-standing programming language built for numeric work, scientific computing, and high-performance systems. It is still used where speed, predictable results, and mature compiler support matter. Teams often keep it in place for core simulation logic that is too valuable to rewrite quickly.
Typical work
- Maintain and extend legacy FORTRAN and modern Fortran codebases
- Improve solver performance and numerical stability
- Refactor modules, common blocks, and interfaces
- Connect Fortran routines with C, C++, Python, or job schedulers
Ecosystem and tooling
Strong specialists know compiler behavior, build systems, and debugging tools across Unix-like environments and Windows where needed. They work with common toolchains such as gfortran, Intel Fortran, and OpenMP or MPI for parallel work. They also understand how Fortran code fits into larger scientific pipelines.
When companies bring in specialists
Companies usually need freelance help when old code is hard to change, a release is blocked, or a numerical routine must be checked before production use. In Germany, this often comes up in engineering, research, energy, automotive simulation, and technical software teams. A good specialist can work remote or on-site, depending on access to code, test data, and domain experts.
What strong professionals do well
Strong Fortran professionals read dense code quickly and keep behavior intact while improving structure. They test edge cases, track compiler differences, and protect results from silent numerical drift. They also document changes clearly so internal teams can maintain the code after handover.
How to choose the right fit
Look for people who have shipped real production changes, not just academic examples. Ask how they handle fixed-form and free-form code, module dependencies, and mixed-language integration. For long-lived systems, experience with Fortran 77, Fortran 90/95, and newer standards is often more useful than broad but shallow language coverage.
Frequently asked questions
Before you brief your next project: the most common questions about Fortran.
Fortran is used for numerical software where performance and stable results matter more than trendy frameworks. Companies rely on it for simulation, modeling, scientific analysis, engineering tools, and other compute-heavy systems. It is common in codebases that have grown over many years and still do important work.
A strong Fortran specialist helps when a critical codebase is old, fragile, or hard to change safely. Many teams need help understanding legacy FORTRAN, improving tests, or adding new interfaces without breaking results. That is especially useful when the original authors are no longer available.
Fortran is often chosen for numeric loops, array-heavy calculations, and predictable performance. C and C++ can be better for general systems work, while Python is often used around the model, not inside the hottest computation path. Many projects combine all three and keep Fortran at the core.
A practical Fortran professional usually knows compilers, build tools, debugging, and parallel runtime concepts. C or C++ integration, Python wrappers, MPI, OpenMP, and shell scripting are also common and useful. Domain knowledge in simulation or scientific computing can matter as much as language syntax.
A capable Fortran specialist can start with source code, build steps, and a clear description of the problem. Access to sample inputs, expected outputs, and test cases makes early work much safer. For legacy systems, a short handover with the internal team is often enough to begin.
Most Fortran tasks can be done remotely if the code, build environment, and test data are accessible. On-site work in Germany is helpful when the system is tightly controlled, the domain is sensitive, or the team needs close workshop-style collaboration. Many engagements use a mixed setup.
Look for evidence of careful code changes, good tests, and clear explanations of numerical trade-offs. A strong Fortran expert can talk about compiler issues, array handling, and how to avoid changing results by accident. Ask for examples of maintenance or modernization work, not only new code.
Yes. Fortran is the modern spelling, while FORTRAN is the older uppercase form that still appears in legacy systems and search queries. Using both terms helps when you want specialists who understand older code and current standards.
The average hourly rate of freelancers in Germany who have used Fortran in their recent projects is 102 €, which corresponds to a daily rate of about 816 € based on an 8-hour working day.
Of the freelancers in Germany who have used Fortran in their recent projects, 91% hold at least a Bachelor's degree, 66% hold at least a Master's degree, and 27% hold a doctorate.
On average, freelancers in Germany who have used Fortran in their recent projects have 30 years of professional experience, with a single engagement typically lasting around 2.7 years.
The most common languages among freelancers in Germany who have used Fortran in their recent projects are English (100%), German (96%), and French (41%).
The most common industries among freelancers in Germany who have used Fortran in their recent projects are Information Technology (78%), Manufacturing (65%), and Automotive (55%).
The most common business areas among freelancers in Germany who have used Fortran in their recent projects are Information Technology (88%), Product Development (78%), and Project Management (76%).
