By contributing to our team, you will not only play a key role in optimizing code generation for quantum computing but also in shaping the future of quantum technology. Your work will ensure that our quantum computers can realize their full potential, unlocking new possibilities for solving some of the world's most challenging problems.


Key Responsibilities:

  • Support a commercially deployed quantum compiler and emulator
  • Design and develop compiler front-end (quantum languages), back-end (machine-specific targeting), and optimization (quantum circuit optimization and classical optimization) passes operating on both classical and quantum operations
  • Benchmark, profile, and iteratively improve the execution performance of our compiler and the quality and performance of quantum programs aligned to current and future architectures
  • Collaborate on the design and implementation of a compiler targeting a real-time, distributed execution environment
  • Work with a diverse team including physicists and other engineering disciplines to solve complex problems
  • Create high quality code in an R&D and rapid prototyping environment

YOU MUST HAVE:

  • Bachelors Degree minimum
  • Minimum 1+ years of industry or post-graduate experience in an engineering, lab, or R&D environment
  • Minimum 3+ years of programming experience with Python, Rust, C++, or similar language
  • Strong understanding of compiler design fundamentals
  • Ability to understand, combine, and apply algorithms to solve complex problems
  • Due to Contractual requirements, must be a U.S. Citizen, permanent resident or green card holder

WE VALUE:

  • Masters/PhD degree in Computer Science
  • Ability to solve complex problems and ability to communicate how you did it
  • Track-record of using python or other rapid prototyping and development tools to solve complex challenges
  • Rust development experience especially including any LLVM or optimization algorithm development
  • Demonstrated ability to work with a variety of algorithms, including tree, graph, SAT, and, at times Machine Learning and other algorithms
  • History of working with and developing for the LLVM toolchain
  • Experience with LLVM IR and MLIR
  • Experience with development of application-specific algorithms, especially where exact/optimal solutions are computationally intractable
  • Proficiency with software testing and deployment tools
Compensation & Benefits:
Non-Incentive Eligible
Estimated Salary Wage: $128,000 - $161,000 Annually
What is in it for you?
-A competitive salary and innovative, game-changing work
-Flexible work schedule
-Employer subsidized health, dental, and vision insurance
-401(k) match for student loan repayment benefit
-Equity, 401k retirement savings plan + 12 Paid holidays and generous vacation + sick time
-Paid parental leave
-Employee discounts

Quantum Computing Recruitment Trends 2025 (UK): What Job Seekers Need To Know About Today’s Hiring Process

Summary: UK quantum computing hiring has shifted from credential‑first screening to capability‑driven evaluation. Employers now value provable contributions across the stack—algorithms & applications, compilation & optimisation, circuit synthesis, control & calibration, hardware characterisation, error mitigation/correction (QEM/QEC), verification/benchmarking, and hybrid HPC/quantum workflows—plus the ability to communicate trade‑offs, costs and feasibility to non‑quantum teams. This guide explains what’s changed, what to expect in interviews and how to prepare—especially for quantum algorithm engineers, quantum software/compilers, experimentalists, quantum control & firmware, cryo/readout engineers, quantum error correction researchers, verification/benchmarking specialists, and quantum‑adjacent product managers. Who this is for: Quantum algorithm/applications engineers, compiler/optimisation engineers, control/firmware engineers, experimental physicists & hardware engineers (superconducting, trapped ion, photonic, spin/neutral atom), cryogenics & RF/microwave, QEC researchers, verification/benchmarking specialists, quantum‑HPC orchestration engineers, and product/BD roles in the UK quantum ecosystem.

Why Quantum Computing Careers in the UK Are Becoming More Multidisciplinary

Quantum computing has long been considered an elite subfield of physics and computer science. But as quantum technologies advance—from fault-tolerant hardware to quantum algorithms and quantum cryptography—they’re moving closer to real applications in finance, materials simulation, optimisation, cryptography and more. As this transition happens, UK quantum computing careers are becoming increasingly multidisciplinary. Quantum systems are no longer just the domain of physicists and quantum software engineers. If quantum technologies are to be trusted, adopted and regulated, professionals must also incorporate expertise in law, ethics, psychology, linguistics & design. In practice, quantum computing projects now intersect with data governance, risk, human interaction, explainability and communication. In this article, we’ll explore why quantum computing careers in the UK are shifting to multidisciplinary roles, how these five supporting fields intersect with quantum work, and what job-seekers & employers should do to keep up in this evolving frontier.

Quantum Computing Team Structures Explained: Who Does What in a Modern Quantum Department

Quantum computing has shifted from lab curiosity to the next frontier of high-impact computing. Across the UK, universities, national labs, start-ups, and established tech and finance firms are building quantum teams to explore algorithms, design hardware, and deliver quantum-ready software. As momentum grows, so does the need for clear, robust team structures. Because quantum R&D spans physics, engineering, computer science, and product, ambiguity about who does what can slow progress, increase risk, and inflate costs. This guide maps the typical roles in a modern quantum computing department, how they collaborate across the research-to-product lifecycle, skills and backgrounds UK employers expect, indicative salary ranges, common pitfalls, and practical ways to structure teams that move fast without breaking science.
