The HCSS internship programme offers a diverse opportunity involving research, analysis, data, communications, networking, copywriting, and policy development. We offer a range of programmes including General, Data, Water, Peace and Security, PR and Communications and Boardroom internships. Internship activities can range from conducting background research, data collection and analysis, co-writing reports and papers, to being involved in the organisation of workshops and conferences. Unlike traditional internships, at HCSS, you’ll be an integral part of a fast-paced professional team. Interns contribute to impactful products for various clients, ranging from government to NGOs to private sector and research organisations. We open internship applications twice a year; upcoming start dates will be announced on our website and social media platforms.
The next round of applications will open on June 1st, 2026.

login@hcss-site2021-05-21 09:28:282021-05-21 16:25:47HCSS Cyber Program InternshipThe General internship is our largest programme and activities covered can include background research, data analysis, data visualisations, report co-writing, and event organisation. Candidates should have a first rate academic background, strong transferable skills, and a keen interest in HCSS research topics such as international relations, defence and security, climate and energy security. A strong basis of analytical, writing and synthesising skills and excellent communication skills in English are required. Candidates must be enrolled as a student at a university during the whole internship period. Keep an eye on our website for the opening!
Of the general interns, one may be chosen for the dedicated Water, Peace, and Security (WPS) project. The WPS partnership, established in 2018, pioneers tools to address water-related security risks and shift from water-conflict to water-peace cycles. HCSS aids WPS in Iraq. We seek motivated interns intrigued by water-related security, particularly those with Arabic proficiency for our Iraq-focused efforts. Interns can engage in cutting-edge research, raise awareness of water-related conflicts, aid dialogues with Iraqi stakeholders, and organise training modules and workshops. Applicants must be university students throughout the internship.
The HCSS Datalab offers an exciting internship to aspiring data scientists with an interest in international relations, defence, economics, climate and energy security. Tasks encompass hypothesis testing, data analysis, data visualisations, research, policy assistance, and workshop involvement. You will work on projects that utilise the latest data analysis tools such as, causal modelling, natural language processing and game theory. Requirements include affinity with computer science, statistics, mathematics, or related fields, fluency in programming languages like Python and strong English communication skills. Candidates must be enrolled as a student at a university during the whole internship period.
The HCSS Internship program enables you to put your academic knowledge into practice, cultivate your personal skills, and acquire invaluable professional experience within a dynamic think-tank setting. Immerse yourself in an intellectually stimulating environment, where you can glean insights from dedicated staff members deeply passionate about their fields. The internship programme affords you ample opportunities to connect with professionals hailing from both Dutch and international organisations.
With our intern mentorship programme, you will be paired with a mentor who will guide your growth, offering support for your personal and professional development. Upon satisfactory completion of your Internship, we can write a reference letter reflecting on your performance at HCSS.
