Postdoc Quantum Torsional Resonators

Job description

The radical theory of quantum mechanics is known to describe the fundamental physics of our universe at the nanoscale: from atoms and fundamental particles from a century ago, to the quantum sensors and computers of today, quantum mechanics governs how these microscopic objects and devices behave. In contrast, at the macroscopic scale, quantum effects are elusive: the macroscopic world seems to follow instead the laws of classical physics. At an even deeper level, despite work of 100 years, physics has yet to find a clear way to integrate gravitational effects into quantum theory. At the same time, quantum experiments with large masses are an outstanding challenge, and will be crucial in addressing how gravity and quantum mechanics can be combined.

In the project, you will design, fabricate, and measure nanomechanical resonators coupled to superconducting quantum circuits with the aim of exploring the fundamental limits of the quantum behaviour of heavy, macroscopic objects. You will work with a team funded by an ERC Advanced proposal to do this using a radical new approach based on silicon nitride ribbon torsional resonators coupled directly via magnetic flux to a superconducting qubit. Building on the exciting flux-coupling concept pioneered in my group, you will bring mechanical experiments into new regimes, using quantum control over heavy objects via a superconducting qubit to build quantum superpositions of unprecedented size. You will develop skills to become an expert in complex nanofabrication as well as an expert in quantum measurements and control with superconducting quantum bits.

You will work in the world-class, state-of-the-art Kavli Nanolab facility in Delft, a unique flagship academic cleanroom in Europe with extensive expertise and specialised facilities for nanofabrication of quantum devices.

You will join a diverse and enthusiastic team of academic staff, PhD students and postdocs in the Steele Lab in the Quantum Nanoscience Department in Delft. You will meet regularly with your supervisors and other team members, and also be encouraged to develop and explore your own ideas. Furthermore, you will collaborate closely with local and international colleagues working in both experimental and theoretical fields to enable you to learn and execute world-leading research.

Job requirements

• A PhD degree in physics
• A PhD degree in electrical or mechanical engineering could also be suitable if strongly motivated by experience with quantum mechanics or nanomechanics

Functioneel Beheerder ServiceNow

Bouw mee aan één ServiceNow-platform voor de UvA en HvA
Binnen het Administratief Centrum/ICT Services (AC/ICTS) werken we aan één geïntegreerde ServiceNow-omgeving voor de Universiteit van Amsterdam (UvA) en de Hogeschool van Amsterdam (HvA). Met meer dan 100.000 studenten en medewerkers zijn we een van de grootste onderwijs- en onderzoeksorganisaties van Nederland.

Ons doel? Processen slimmer, eenvoudiger en gebruiksvriendelijker maken, voor iedereen.

Om dat te bereiken zoeken we een Functioneel Beheerder ServiceNow die zorgt voor de vertaling van verzoeken vanuit beide onderwijsorganisaties. Iemand die klant- en procesgericht denkt, die luistert en doorvraagt. Die de vraag achter de vraag van gebruikers weet te achterhalen en die kan vertalen in functionele wensen.

Dit ga je doen
Het Enterprise Service Management (ESM)-team bestaat momenteel uit twee deelteams. Het ene richt zich op het in kaart brengen en uitwerken van gebruikersverzoeken, het andere op de technische realisatie daarvan. Als functioneel beheerder ben je onderdeel van het eerste team. Je werkt daarin samen met andere functioneel beheerders en business analisten. Samen achterhalen jullie wat gebruikers van zowel de UvA als de HvA nodig hebben en werken jullie dit uit tot heldere functionele requirements. Het technische team gebruikt deze requirements vervolgens als basis voor de realisatie binnen het ServiceNow-platform.

Je houdt je onder andere bezig met:

• Aannemen en registreren van wijzigingsaanvragen
• Behandelen en eventueel registreren[MS1.1] van incidenten
• Contacten onderhouden met eindgebruikers om hun wensen duidelijk te krijgen
• Het vertalen van wensen in functionaliteiten of het bespreken van alternatieve oplossingen
• Testen van opgeleverde functionaliteit
• Trainen van gebruikers
• Regressietesten tijdens upgrades van ServiceNow
• Documenteren van bevindingen, genomen acties en conclusies

Dit vragen we van je

• Je hebt minimaal drie jaar ervaring in dienstverlening binnen het hoger onderwijs
• Je hebt ervaring als functioneel beheerder of als keyuser
• Je hebt kennis van en ervaring met onderwijslogistieke systemen of andere kernsystemen, zoals SIS, Planon of SAP
• Je bent bekend met servicemanagementsystemen, kennis van ServiceNow is een pre, net als kennis van BiSL en/of ITIL
• Je hebt affiniteit met procesanalyse en met het aanleren van nieuwe systemen[MS3.1]
• Je werkt nauwkeurig en gestructureerd, en denkt in oplossingen in plaats van in problemen
• Je communiceert makkelijk met collega's uit het onderwijs én de techniek
• Je spreekt vloeiend Nederlands.

Dit bieden we je nog meer
Naast een goed salaris van minimaal € 3.873,- tot maximaal € 5.264,- bruto per maand (op basis van 38 uur exclusief 8% vakantiegeld, een 13e maand met een uitgebreid pakket secundaire arbeidsvoorwaarden waaronder een ruime vakantieregeling, bieden we je:

• Een jaarcontract met een proeftijd van twee maanden, met uitzicht op een vast contract na 1 jaar;
• Mooie projecten waarmee je het verschil kunt maken;
• Een enthousiast team met echte vakspecialisten;
• De bijzondere dynamiek van twee grote instellingen (UvA en HvA);
• Leuke teamuitjes en activiteiten;
• Vers fruit op locatie en mogelijkheid tot het boeken van stoelmassages.

In dit team/bij deze afdeling, kom je te werken
Je komt te werken in een enthousiast, multidisciplinair en gezellig team dat in het midden staat van twee organisaties waar onderwijs en onderzoek centraal staan. Het productteam kent alle leeftijden, telt elf leden inclusief scrummaster en productowner en werkt op de dinsdag en donderdag fysiek samen op kantoor.

In 2025 hebben we een spannende migratie van TOPdesk naar ServiceNow onder grote druk succesvol afgerond. We willen nu onze kennis en backlog op niveau brengen, want de organisatie staat te springen om nog meer uit ServiceNow te halen. Om dit te bereiken werk je nauw samen met de Platformarchitect en een Senior Business Analist. Er is veel ruimte voor groei en vernieuwing.

We bieden je alle mogelijkheden voor persoonlijke en professionele ontwikkeling.

PostDoc position on Wafer Bonding Physics for 3D Chip Integration

Wafer-to-wafer bonding is a key enabling technology for future 3D chip integration, where chips are stacked and interconnected to create faster, more compact and more energy-efficient semiconductor devices. However, the detailed mechanisms that determine bonding quality are still not sufficiently understood. In particular, the interplay between surface properties, wafer morphology, and the resulting bonding performance is still largely optimized empirically.

In this postdoctoral project, you will develop and validate experimental methods to study wafer bonding in a quantitative and physics-based way. You will work on wafer bonding measurements and combine these with advanced surface metrology. It is relevant to have experience with analysis techniques such as AFM, WLI, contact-angle, XPS, infrared metrology.

You will work in the XUV Optics group at the University of Twente, embedded in the MESA+ Institute for Nanotechnology. The project offers a combination of hands-on experimental work, data analysis, physical interpretation and close interaction with industrial partners. You will contribute to a scientifically challenging and industrially relevant topic, with the aiming at predictive relations between measurable wafer surface properties and bonding performance for next-generation 3D chip integration.
