Job summary

QuantWare, Delft, Netherlands, is seeking a 3D Packaging Engineer to collaborate with the engineering team on physically realizing VIO products. You will operate and fine-tune high-precision assembly equipment to meet stringent tolerances for quantum devices.

The role requires hands-on experience with semiconductor assembly platforms and a strong foundation in 3D integration concepts, including TSVs and interposers, under thermal and cryogenic conditions. A hybrid setup is offered.

Qualifications

• Education required: BS, MS, or PhD in Mechanical Engineering, Mechatronics, Physics, Materials Science, or related field.
• Experience: 3–5 years operating and adjusting high-accuracy semiconductor assembly platforms.
• Proven ability to achieve tight placement tolerances (~1 µm) in R&D or pilot production.

Responsibilities

• Tooling Adaptation: modify and calibrate high-precision assembly equipment to meet unique 3D integration specs.
• Process Optimization: develop/refine placement and bonding processes for non-standard substrates; test adhesives, glues, and solders for extreme conditions.
• 3D Assembly Execution: execute complex integration strategies including multi-die stacking and interposer-based 3D architectures.

Job description

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 Engineer, you will collaborate closely with our engineering team to physically realize our VIO products. You will operate, adapt, and fine-tune high-precision assembly equipment to meet the precise tolerances required for optimal device performance.

What You'll Be Doing

• Tooling Adaptation: Assist in modifying and calibrating high-precision assembly equipment (e.g., flip-chip bonders, die attach machines) to meet unique quantum 3D integration specifications.

• Process Optimization: Help develop and refine placement and bonding processes (thermo-compression bonding, laser-assisted bonding, coldwelding) for non-standard substrates. Test adhesives, glues, and solders to determine which materials survive extreme thermal cycling and cryogenic vacuum conditions.

• 3D Assembly Execution: Execute complex integration strategies, including multi-die stacking, interposer-based 3D architectures, and orthogonal (vertical) chip placement.

Your Profile

• Education: BS, MS, or PhD in Mechanical Engineering, Mechatronics, Physics, Materials Science, or a related field.

• Tooling Experience: 3–5 years of hands-on experience operating and adjusting high-accuracy semiconductor assembly platforms.

• Precision Assembly: Demonstrated experience achieving tight placement tolerances (around 1µm) in an R&D or pilot production environment.

• 3D Integration Knowledge: Solid foundational understanding of 3D integration (TSVs, micro-bumps, interposers) and how structural materials behave under thermal stress, high vacuum, or cryogenic conditions.

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 salary that reflects the impact and importance of the role (and of course 8% holiday allowance)

Pension that’s built to last - A generous and future-proof pension plan that includes partner and dependent coverage.

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

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 great candidates don't always follow a straight path, and we value diverse experience, perspectives, and ways of thinking. We know this helps us make better decisions, drives more innovation, and strengthens our culture.

As part of our recruitment process, candidates may be required to undergo pre-employment screening.
