Equal1 is building the world’s first practical, fully integrated quantum computer. In Timișoara, we are expanding our engineering team with talented young engineers who want to shape the software foundations of quantum computing.
We are looking for a Software Stack / Framework Engineer who is passionate about bridging classical computing with next-generation quantum architectures in hybrid architectures. You will help design, implement, and optimize the software layers that make the Equal1 QPU accessible, fast, and scalable, from low-level gate libraries to high-level developer frameworks.
Main Duties and ResponsibilitiesDevelop and maintain the software stack that interfaces with Equal1’s silicon-based QPU.
Build tools, APIs, and frameworks that enable researchers and customers to run quantum programs efficiently.
Collaborate with hardware, algorithms, and control teams to design hybrid classical–quantum workflows.
Optimize middleware, compilers, and library components for performance and reliability.
Contribute to continuous integration, testing, and system-level validation.
Strong programming skills (Python, C/C++, or similar).
Solid understanding of computer architecture, embedded systems, compilers, or distributed systems.
Knowledge of LLVM / MLIR compiler infrastructure or compilation strategies is a plus
Familiarity with quantum computing concepts (gate models, qubits, noise) is a plus—deep expertise is not required.
Curiosity, creativity, and the ability to work across classical and quantum paradigms.
Desire to grow long-term in an emerging, cutting-edge field.
Join us if you want to help build the software foundation of a new computing era.

What We Do
Equal1 Laboratories is accelerating the introduction of useful, cost effective quantum computers within a three-year time horizon. The company has developed a disruptive, scalable and cost-effective quantum computing technology, based on a commercially available silicon semiconductor process. Our solution uses nanometer-scale quantum dots to form qubits on a standard silicon CMOS process. Along with silicon qubits, we have integrated all functions required for a quantum processing unit (QPU) – the brain of the quantum computer – which operates at 3 kelvin with over 10 million transistors. This is the first integrated quantum processing unit of its kind. The company’s server-sized demonstrator, called Alice, uses the second generation, fully functioning QPU. Alice uses our 424 quantum-dot-array structure to demonstrate early indications of the impact this technology can have on AI applications. Equal1 is developing its silicon-based quantum computer technology in collaboration with University College Dublin, with hardware development laboratories in Fremont, California and a silicon design center at NovaUCD in Dublin, Ireland
