Python Engineer

At ALTEN, we know that the success of our projects is due to the people who make up our team. That’s why, if you have experience as a Python Engineer , we are committed to boost your talent. Do you want to build the world of tomorrow, today? Keep reading!

Location: Remote from Spain.

Main tasks:

• Build and maintain the sandboxes, data pipelines, and tooling that support rapid experimentation across the portfolio.
• Take prototypes through *light hardening* to handover-readiness after a "go" decision — deployable on the organization's agentic development platform — with full production hardening owned by the receiving team (R&D consults; it does not own production).
• Design and ship internal tools and applications end-to-end, including light front-end where needed.
• Partner with the Lead Research Scientist and external research teams to turn ambiguous research code into reliable, maintainable systems.
• Mentor AI Research Interns on engineering practice.
• Own tooling and infrastructure choices under right-sized, pre-production governance — rapid iteration without production-grade overhead.
• Keep infrastructure and pipeline designs documented as a working habit, so no system depends on a single person's memory.

What do we need?

• Full-stack capable software engineer — backend, data pipelines, and basic frontend.
• Experience taking ML / data-science prototypes through *initial* productionization (early-stage MLOps to handover-readiness), alongside other core engineering strengths — e.g. building data pipelines, experiment and evaluation tooling, model/API integration, and rapid prototyping.
• Comfortable working directly with ambiguous, research-grade code.
• Cloud and infrastructure experience.
• Nice-to-have: Experience building LLM-based tools and agents. Working ML / data science literacy (valued, not required as the primary craft).

What can we offer you?

• To be part of a large, competitive company that is continuously growing.
• To join an innovative and dynamic team of highly qualified professionals and a positive work environment.
• Specialized training and continuous professional development.
