Job description

The position is hosted at LIX, the computer science laboratory of École polytechnique (joint research unit CNRS / École polytechnique, UMR 7161), in the team of Kevin Vermeulen (CNRS researcher), whose research focuses on Internet measurements, Internet topology and routing security. It is funded by the HIJ-IX project (“Attacks in IXPs: opportunities, impacts and countermeasures with the nxthdr.dev platform”), a 36-month project (October 2026 - September 2029) selected in wave 6 of the call for projects of the CIEDS, the Interdisciplinary Centre for Defence and Security of IP Paris, in partnership with the French Defence Innovation Agency (AID). HIJ-IX brings together LIX, UCLouvain, the Federal University of Mato Grosso do Sul and the Federal University of Rio Grande (Brazil), with the support of the IXP operators France-IX and IX.br., nxthdr is an open, non-profit Internet research and teaching platform, led by Kevin Vermeulen and operated by the nxthdr association (French non-profit association since October 2025). It operates its own research network, AS215011 (IPv6), with servers connected to large IXPs in Europe - France-IX (Paris), NL-ix (Amsterdam), LOCIX and FogIXP (Frankfurt) - as well as IX.br in Brazil. nxthdr offers two services, both currently in alpha version:

  • Peering platform (PeerLab): researchers rent IPv6 prefixes and advertise them on the Internet from several IXPs, with feedback on the propagation of these announcements (BMP data, visibility with public road collectors, RPKI ROA management).
  • Probing platform (Saimiris): Ping and traceroute campaigns from distributed measurement points, using anycast and unicast source prefixes.

Reporting to the Scientific Manager of the project, your role will be to ensure the operation and evolution of the nxthdr platform, the experimental infrastructure of the HIJ-IX project.

The position is offered on a part-time basis (50%).

You will have to guarantee the availability, reliability and safety of use of the platform, extend its coverage (new IXPs, new peers, federation with PEERING) and provide HIJ-IX researchers (PhD student, postdoc, academic partners) with the engineering support they need to conduct BGP (Border Gateway Protocol) experiments and measurements in real IXPs.

As such, you will carry out the following main missions:

Platform operation and availability:

  • Operate and maintain in production the nxthdr platform (AS215011);
  • Configure routers, servers, and virtual machines in IXPs, processing chains, and databases;
  • Supervise and alert on possible breakdowns;
  • Ensure security updates, backups, incident management;
  • Maintain documentation

Extension of platform coverage:

  • Select, with the research team, and deploy new points of presence in other IXPs, in Europe and on other continents, taking care of the technical and administrative procedures.

Federation with PEERING:

  • Design and implement nxthdr federation with the peering platform, so that experiments can combine the measurement points and connectivity of both platforms.

Peering:

  • Establish and maintain peering sessions with more ASs (Autonomous System), via IXP route servers and bilateral sessions, especially with large content and cloud networks like Cloudflare and Fastly, to improve the diversity and realism of platform connectivity.

New features:

  • Propose, design and develop new functionalities for the platform (e.g. new types of experiments, API and CLI enhancements, new open datasets, self-service access for external researchers), based on the needs of the research team and the user community;
  • Contribute to the opening of the platform to the entire scientific community.

User support:

  • Assist researchers and students in using the platform, and review and integrate contributions into open source code.

Complementary activities:

Contribute to research artifacts (open datasets, code) and publications related to the platform, responsible disclosure of results to IXP operators, as well as technical presentations (e.g. at network operator forums like RIPE or FRnOG).

  • Special constraints : Occasional travel (IXP sites and data centers, project meetings, conferences) and occasional interventions outside working hours in the event of a critical incident on the platform.

Requirements

You have a master’s degree (Bac+5), an engineering degree or a doctorate in computer science, and ideally have at least 2 years of experience in the operation of network infrastructures (access provider, IXP, hosting provider).

We encourage you to highlight your strong personal or open source projects in this area.

Fluent level of French and English required.

About the company

L’École polytechnique (surnommée l’X), est un établissement d’enseignement supérieur et de recherche de niveau mondial, fondée en 1794 au cours de la révolution française. Il s’agit d’une École militaire, elle est placée sous la tutelle du ministère des Armées. L’École polytechnique est membre fondateur de l’Institut Polytechnique de Paris aux côtés de quatre autres Grandes Écoles d’ingénieurs : l’ENSAE Paris, l’ENSTA Paris, Télécom Paris et Télécom SudParis.

Largement internationalisée (40% de ses étudiants, 40% de son corps d’enseignants), l’École polytechnique associe recherche, enseignement et innovation au meilleur niveau scientifique et technologique. Sa formation promeut une culture d’excellence à forte dominante en sciences, ouverte sur une grande tradition humaniste.

Avec ses 23 laboratoires, dont 22 sont des unités mixtes de recherche avec le CNRS, le centre de recherche de l’X travaille aux frontières de la connaissance sur les grands enjeux interdisciplinaires scientifiques, technologiques et sociétaux.

Le modèle stratégique de l’École polytechnique repose sur trois piliers : enseignement, recherche et, innovation. L’innovation et l’entrepreneuriat sont devenus un axe majeur du développement de l’École, notamment avec le lancement en 2015, d’un accélérateur dédié pour faire émerger des start-ups technologiques.

Soucieuse d’attirer les meilleurs talents au sein de ses équipes d’enseignements-chercheurs, de son personnel et d’amener toujours plus d’étudiants vers ses formations d’excellence, l’École polytechnique est résolument engagée en faveur de la diversité sociale et de genre et de l’égalité Femmes-Hommes.

L’École polytechnique agit sur les grands enjeux du développement durable. En tant qu’acteur responsable, elle met avec ses partenaires de l’Institut Polytechnique de Paris, l’enseignement, la recherche et l’innovation au service de la connaissance sur l’évolution des écosystèmes, du changement climatique et de l’élaboration de solutions pour promouvoir une prospérité durable et inclusive qui réponde aux besoins présents sans compromettre l’avenir des futures générations.
