Overview

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.

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. Experience of 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
