Quantum Compiler SW Developer - Physics Oriented

  • Product & R&D
  • Israel
  • Intermediate
  • Full-time Description At Classiq Technologies, we're shaping the future of quantum computing. Our platform lets developers and enterprises design, optimize, and deploy quantum algorithms at scale, and is trusted by Fortune 500 leaders and global governments. Classiq is backed by 70 patents.

We're looking for a science-oriented software developer with a strong background in quantum information and quantum algorithms to help build our quantum compiler. We hire across levels — from researchers coming out of a strong M.Sc./Ph.D. to seasoned engineers.

The team & what you'll work on

  • The Qmod language and its compiler toolchain — semantics, type system, intermediate representation, and the next-generation compilation pipeline

  • The synthesis engine that lowers high-level programs into circuits optimized for width (qubits/ancillas), depth, and gate count under user constraints

  • Implement and improve quantum synthesis algorithms from the literature — arithmetic, multi-controlled-gate synthesis, Hamiltonian simulation (Trotterization, qDRIFT), state preparation, uncomputation, and fault-tolerant compilation (Clifford+T, routing)

  • Resource estimation for quantum programs

  • Debugging tools for quantum programs — for example, a visual model of the high-level program that lets users inspect and troubleshoot what they wrote

  • Compiler-pass performance and correctness, benchmarked against real algorithms (e.g. Shor's algorithm, quantum phase estimation, QSVT) What you'll do

  • Design and develop the capabilities of the quantum compiler

  • Contribute to the architecture of the quantum compiler and the definition of our high-level quantum programming language

  • Collaborate closely with product and algorithm teams to deliver production-ready quantum capabilities Who you are

  • M.Sc. or higher in Physics, Computer Science, or a related field, with a thesis or equivalent research in quantum information — the heart of the role

  • Solid understanding of quantum computing principles and hands-on experience developing quantum algorithms

  • Able to write real, maintainable code and eager to build production software — a strong plus

  • Passion for building tools that empower developers and researchers Bonus points

  • Experience with quantum software frameworks (e.g. our platform, Qiskit, Cirq, PennyLane)

  • Strong Python

  • Broader computer-science algorithms background

  • Prior experience in compiler or synthesis-engine development Why join us

  • Join a very well-funded, rising startup in an exploding field

  • Work on high-impact initiatives at the core of the product

  • A collaborative culture grounded in scientific excellence and commercial ambition

  • Competitive compensation, equity, and benefits
