How you'd explain your job at a party

I help to protect the internet against DDoS attacks

What you'll be doing

On a two-year contract, you'll be helping to develop a DDoS clearing house. That's a system that enables various (critical) infrastructure operators to automatically compile, share and utilise 'fingerprints' (characteristic profiles) of individual DDoS attacks. The clearing house will provide an extra layer of security, complementing traditional anti-DDoS services. Your work will help empower infrastructure operators to jointly and proactively increase anti-DDoS resilience and diminish the impact that attacks have on the community.

  • collaborate with partners from the Netherlands and other European countries to run a DDoS clearing house pilot project (TRLs 5-7), using DDoS-DB as the starting point

  • redesign DDoS-DB to create a flexible DDoS clearing house

  • continuously improve, extend, test and document the DDoS clearing house software and the test hub at SIDN Labs

  • monitor the development of DDoS attacks and systems for detecting and countering such attacks, including emerging internet standards such as DOTS

  • work iteratively on the basis of a project plan, which involves you meeting deadlines and reporting on progress

  • communicate your research results to the wider internet community

What we want

SIDN Labs helps to make the internet secure and stable for everyone by doing research in various fields. And that's where you come in. As a software engineer research, you're interested in internet security, you've got relevant knowledge and you feel at home in a research environment. You also want to play your part in improving the protection of critical internet services. In short, you'll be an asset to our team.

  • MSc in Computer Science or similar domain

  • at least 4 years' experience in a research environment

  • experience designing distributed systems, preferably with a focus on internet security and resilience

  • linux software expertise

  • a responsible attitude to working with privacy-sensitive and security-sensitive information

  • good communication skills in both Dutch (basic level) and English (expert level)

About us

SIDN, in full the Foundation for Internet Domain Registration in the Netherlands, is an independent organisation that manages the .nl domain. In 2017, we joined forces with Connectis to reinforce the market for digital identities as well.Connectis supplies software and ID tokens for secure access to public and private services. There's more to domain name registration and secure log-ins than you might expect. We therefore have a team of 150 people dedicated to ensuring that the Dutch internet is as secure and trustworthy as possible. Some are based in Arnhem, others in Rotterdam.

Take a look at the missions and visions of SIDN and Connectis for a fuller picture of who we are and what we stand for. At SIDN and Connectis, you'll see more jeans and tee-shirts than sharp suits. It's a setting where you can be yourself. And there's always something going on: family days, Christmas dinners, sports days, barbecues and even weekends away together. Join in or do your own thing; it's fine either way. Maybe we'll see you soon?

What you can expect

You'll be working on two projects. One is a Dutch engineering-oriented project, while the other is a more European research-oriented project. Collaboration with peers is an important feature of the role, since you'll be interacting with people from various backgrounds (data scientists, software engineers, operators, academics). You'll also be sharing your results with colleagues on the projects, within SIDN and within the operational and academic communities.

By car, it's easy to reach our offices from the A12 motorway. Coming by public transport? We're about twenty minutes from Arnhem Central Station by bike, or you can get the bus heading for IJsseloord 2.
