Engineering internships 2023

Tarides is an international software company with offices in Cambridge (UK), Paris (France) and Chennai (India), founded in 2018 by pioneers of systems and functional programming. We have a worldwide presence with collaborators working remotely from the US, Australia, Canada, India, Japan, and across Europe. We have a solid academic background with connections to the University of Cambridge, Inria, and IIT Madras. Our diverse team of 80+ people performs groundbreaking innovation, feature development, and crucial maintenance of OCaml-based projects.

Some of those projects include the OCaml Platform, a series of crucial tools for OCaml at an industrial scale; MirageOS, an operating system that constructs unikernels for secure, high-performance applications; Irmin, a library for building mergeable, branchable distributed data stores, and the highly complex and award-winning Multicore project which will become part of the mainline OCaml compiler.

Tarides was previously part of the Founder program of Station F in 2018, and was selected for the “Concours d’Innovation i-Lab” organised by the French Ministry of Higher Education, Research, and Innovation in partnership with Bpifrance. Tarides was also recognised during the FIC (International Cybersecurity Forum) 2020 fair, the leading European event on cybersecurity. These awards acknowledge the high quality of the solutions developed by Tarides, and emphasise the interest they have gained from the cybersecurity community.

In 2022, OCaml Labs (a spinout from the University of Cambridge) and Segfault Systems (a spinout from IIT-Madras) both joined Tarides, aligning towards our mission: empowering developers, communities and organisations to adopt OCaml as their primary programming experience by providing training, expertise and development services. 

Work and Responsibilities

Tarides internships are an excellent opportunity to participate in open-source functional programming with tangible real-world applications.

We are looking for curious and passionate interns to join us in tackling hard problems in technology. As an intern, you will have the opportunity to work with experienced mentors on impactful projects closely. In the past, our interns have worked on a variety of interesting projects, including adding NixOS support for MirageOS unikernels and running Irmin server in the browser.

Our internship program runs throughout the year, but we host most interns during the summer. We can host interns in our Paris, Cambridge, or Chennai offices based on the projects chosen. In specific cases, we are also open to remote internships.
