Who this role is best for

Aimed at senior engineers with 7+ years of high-accuracy semiconductor assembly experience who thrive in R&D environments pushing tooling beyond factory specs.

Best fit for

Senior engineers comfortable overriding factory settings on precision equipment
— “knows which bolts to turn and which sensors to override”
Materials scientists experienced with cryogenic-compatible adhesives and solders
— “materials that must remain stable in high-vacuum or cryogenic environments”
3D integration specialists familiar with thermal stress behavior
— “Deep understanding of 3D integration and how these structures behave under thermal stress”

Things to consider

Relocation to the Netherlands required for non-local candidates
— “If you’re moving to the Netherlands, we’ll make the transition seamless”
Pre-employment screening may be part of the hiring process
— “candidates may be required to undergo pre-employment screening”

How to stand out

Document specific instances where you achieved sub-micron placement accuracy
— “Proven track record of achieving <1µm (or even <0.5µm) placement accuracy”
Highlight vendor co-development experience in tooling modifications
— “Interface directly with equipment manufacturers to drive co-development of specialized hardware”
Showcase materials testing for extreme thermal cycling applications
— “materials that can meet our alignment requirements while surviving the extreme thermal cycling”

ABOUT US
QuantWare is building the world’s most powerful quantum processors to solve humanity's greatest challenges. We do this with our unique VIO™ technology, the only QPU architecture that breaks the hardware barriers that have held quantum computing back, unlocking the path to MegaQubit quantum processors.
With VIO, we are paving the way for the hyper-scale quantum computers that will change the world. And delivering on that vision demands people who don’t shy away from tackling the hardest challenges of our time. That’s where you come in!
As a 3D Packaging & Tooling Engineer, you won't just be running a recipe, you will be the lead architect for how our VIO products are physically realized. You will take high-precision assembly machines and push them beyond their factory specs to handle novel 3D architectures and the precise tolerances required for optimal device performance.
WHAT YOU'LL BE DOING
Tooling Adaptation: Lead the modification and customization of high-precision assembly equipment (e.g., flip-chip bonders, die attaches) to meet unique quantum 3D integration requirements.
Advanced Process Development: Develop sub-micron placement and bonding processes (thermo-compression bonding, laser-assisted bonding, coldwelding) for non-standard substrates. Lead the evaluation of glues, adhesives, and solder materials. You will determine which materials can meet our alignment requirements while surviving the extreme thermal cycling and vacuum conditions of a dilution refrigerator.
Non-Standard 3D Assembly: Design and execute "out-of-the-box" integration strategies, including multi-die stacking, interposer-based 3D architectures, and orthogonal (vertical) chip placement.
Vendor Management: Interface directly with equipment manufacturers to drive co-development of specialized hardware.
YOUR PROFILE
Education: BS/MS/PhD in Mechanical Engineering, Mechatronics, Physics, or Materials Science.
Deep Tooling Fluency: 7+ years of hands-on experience with high-accuracy semiconductor assembly platforms. You are the person who knows which bolts to turn and which sensors to override to get the results you need.
Precision Assembly Expertise: Proven track record of achieving <1µm (or even <0.5µm) placement accuracy in a production or R&D environment.
3D Integration Knowledge: Deep understanding of 3D integration (TSVs, micro-bumps, or Interposers) and how these structures behave under thermal stress. Experience with materials (solders, underfills, adhesives) that must remain stable in high-vacuum or cryogenic environments.
Education: BS/MS/PhD in Mechanical Engineering, Mechatronics, Physics, or Materials Science.
WHAT WE OFFER:
At QuantWare, you’ll be part of a high-performing team of world-class experts in an ambitious, fast-moving environment. From day one, you’ll have the trust, tools, and support to do your best work. Here’s what you can expect:
Competitive salary - A competitive monthly salary, plus an 8% annual holiday bonus paid out each May
Pension that’s built to last - A future-proof pension plan that includes partner and dependent coverage. QuantWare covers 63% of the premium
Flexibility built on trust - We focus on outcomes. Work flexibly, in a hybrid setup, with an open vacation policy that lets you manage your time
Relocation support - If you’re moving to the Netherlands, we’ll make the transition seamless. We cover visa support, temporary housing in most cases, and help securing the expat tax benefit for eligible candidates.
Personal growth - We invest in your L&D, with a budget available to each team member, dependent on their individual ambitions, development needs, and performance
A connected team - We make space to celebrate wins together, with team events, offsites, and spontaneous moments that bring us closer
DIVERSITY & INCLUSION AT QUANTWARE
We’re an ambitious company, not only for our goals but also to become an even more diverse and inclusive team. We know this helps us with better decisions, more innovation, and strengthens our culture. In particular, we’d love to see more women in the quantum industry!
So if you’re a female talent, excited about this opportunity but don’t meet every single requirement, we still encourage you to apply.
As part of our recruitment process, candidates may be required to undergo pre-employment screening.
