(Senior) Haskell Developer (m/f/d)

Natuvion Compose is a domain-specific language developed for Natuvion Migrate, our orchestration and ETL platform that simplifies complex data transformation and migration workflows. Compose is designed for clarity, correctness, and composability—empowering developers to express sophisticated data logic with precision and confidence. Built in Haskell, it brings the power of functional programming to enterprise-scale data engineering.

About the Team

You’ll join a focused and highly skilled team of language designers, compiler engineers, and functional programming experts. We work at the intersection of programming language theory and real-world data challenges, building tools that are both elegant and practical. We value clean abstractions, thoughtful design, and a collaborative, research-informed approach to engineering.

Why Join Us?

• Help shape the future of declarative programming in enterprise data systems

• Work on a modern Haskell-based compiler and language stack with real-world impact

• Contribute to the evolution of Compose and the Dhall compiler, and influence the direction of our language ecosystem

• Enjoy a remote-friendly, flexible work environment with a strong culture of autonomy, ownership, and continuous learning

• Collaborate with a team that values academic rigor, open-source contributions, and pragmatic problem-solving

Your Responsibilities

• Design, prototype, and integrate new functionality into the Compose language and framework using Haskell

• Extend and enhance the Dhall compiler with new language constructs and adapt related tooling

• Actively contribute to the design and development of the language, its components, infrastructure, and standard library

• Participate in code reviews, design discussions, and the continuous improvement of our development practices

Your Qualifications

• Master’s or Ph.D. in Computer Science or a related field with a strong academic record, or equivalent practical experience

• Deep expertise in functional programming, particularly with statically typed languages—Haskell experience is essential

• Demonstrated experience in designing, building, and optimizing compilers and/or interpreters

• A pragmatic mindset: you enjoy exploring elegant solutions but also like to see your code run in production

• Either professional experience with functional programming in industry, or a strong portfolio of open-source or personal projects that show your capabilities—we care more about impact than years
