Software Engineer (Quantum Platform and Tools)

Advance practical quantum computing through robust, production-grade software. Haiqu is building a world-leading software platform that enables previously impossible applications on modern quantum processors. Our full-stack approach has shown industry-first results in pilots with leading quantum early adopters. Backed by top investors, we offer a unique opportunity to join a fast-growing team and shape the development of the Quantum Computing software stack, allowing researchers and engineers to build meaningful applications without worrying about low-level intricacies.


We are looking for a Software Engineer (Quantum Platform and Tools) to contribute to the development of core components of our stack—from designing performant transpilation passes and hardware integrations to expanding our cloud-native SDK and CI/CD pipelines.


Responsibilities

  • Design and implement the hybrid quantum-classical workflow orchestration. Integrate advanced error-mitigation techniques, develop novel quantum application primitives, and optimize system performance (including low-level implementations where necessary)
  • Extend and maintain Haiqu's SDK, developer tools, APIs, and backend systems to deliver a seamless and robust quantum development experience.
  • Develop and optimise circuit transpilation and mapping strategies tailored to the constraints of multiple quantum hardware back-ends
  • Build and maintain hardware-integration layers for a growing set of quantum providers
  • Evolve our cloud infrastructure, CI/CD pipelines, and monitoring to ensure secure, scalable, and reliable system performance
  • Write thorough tests, benchmarks, and documentation to maintain code quality and reproducibility across the stack

Strong Plus

  • Basic quantum transpiler knowledge, such as:

    • Quantum circuit optimization
    • Gate decomposition and mapping
    • DAG structures and graph manipulation
    • Basis gate sets and device-specific transformations


  • Experience working close to quantum hardware APIs. API-level interaction and understanding of device-specific properties (e.g., coherence times, gate fidelities, execution queues)

Requirements

  • Strong experience in Python and modern software engineering practices
  • Be comfortable with low-level programming when needed (e.g. C++, Rust, C)
  • Strong software engineering background, including:

    • Design patterns
    • Data structures and algorithms
    • API design (REST)
    • Working with databases (SQL and NoSQL)
    • Writing documentation and integration tests


  • Understanding of functional programming concepts (e.g. monoids, composition, higher-order functions)
  • Familiarity with quantum computing concepts such as:

    • Quantum circuits
    • Measurements, observables
    • Noise channels
    • Error mitigation
    • Error-correction
    • Quantum Machine Learning


  • Prior exposure to quantum SDKs (e.g., Qiskit, Cirq, PennyLane) and Quantum simulators
  • Hands-on experience with DevOps and infrastructure tools:

    • Docker
    • Cloud environments (GCP and AWS)
    • CI/CD workflows



Comfortable working remotely and asynchronously across time zones.

New Quantum Computing Employers to Watch in 2026: UK and International Companies Advancing Quantum Careers

Quantum computing is no longer confined to research labs. As companies convert quantum theory into testable products, algorithms, and computing platforms, demand for professionals with quantum knowledge — whether physics, algorithms, software development, or hardware engineering — is rising. In 2026, quantum computing organisations are securing significant funding, industry partnerships, and contracts across sectors such as energy, finance, telecommunications, defence, and healthcare. For candidates exploring opportunities on www.QuantumComputingJobs.co.uk , understanding which employers are hiring now and scaling quantum teams is crucial. This article profiles the new and high‑growth quantum computing employers to watch in 2026, with a specific focus on UK‑based innovators, international firms with UK operations, and leading global quantum organisations.

How Many Quantum Computing Tools Do You Need to Know to Get a Quantum Computing Job?

Quantum computing is one of the most exciting frontiers in science and technology — and the job market reflects that excitement. But for aspiring practitioners, the sheer number of tools, frameworks, programming languages and hardware platforms can feel overwhelming. One job advert mentions Qiskit, another talks about Cirq or Pennylane. You see references to quantum annealers and superconducting qubits, to measurement hardware and simulators, to noise mitigation libraries and cloud platforms. It’s easy to conclude that unless you master every quantum tool, you’ll never get a job. Here’s the honest truth most quantum computing hiring managers won’t explicitly tell you: 👉 They don’t hire you because you know every tool — they hire you because you can apply the right tools to solve real problems and explain why your solutions work. Tools matter, but context, understanding, judgement and results matter more. So how many quantum computing tools do you actually need to know to succeed in a job search? The real answer is significantly fewer than most people assume — and far more focused by role. This article breaks down what tools really matter in quantum jobs, which ones are core, which are role-specific, and how you can build a coherent toolkit that employers actually value.

What Hiring Managers Look for First in Quantum Computing Job Applications (UK Guide)

Quantum computing is one of the fastest-evolving fields in technology, blending physics, mathematics, computer science and engineering. Roles in this space — from Quantum Algorithm Developer and Quantum Software Engineer to Quantum Research Scientist and Quantum Hardware Specialist — are highly sought after, and hiring managers are exceptionally selective. Because quantum computing is complex and multidisciplinary, recruiters and hiring managers look for clear, concrete evidence of relevant expertise and impact right at the start of your application. They often decide whether to read your CV in detail within the first 10–20 seconds, based on a handful of high-value signals. This guide breaks down exactly what hiring managers look for first in quantum computing applications, how they assess CVs and portfolios, and what you can do to optimise your application to get noticed in the UK quantum job market.
