Singapore ENTROPICA LABS PTE. LTD. Full time

**About Entropica Labs**:
Entropica Labs develops advanced quantum computing software with a focus on quantum error correction, fault-tolerance, and scalable quantum computing workflows. Our flagship software library, **Loom**, is designed to support the development, simulation, and deployment of quantum error correction schemes on real-world quantum devices.

We are seeking a **Quantum Compiler Engineer**to help build and extend the **compiler toolchain**in Loom, enabling seamless integration between high-level logical gate descriptions and hardware-specific execution layers.

**Role Overview**:
In this role, you will design, develop, and maintain compiler infrastructure within Loom, bridging **logical gate definitions**and **low-level machine dialects**such as **MLIR**, **QIR**, and **QASM**. You will work closely with other team members to ensure that Loom’s compiler toolchain is flexible, hardware-aware, and optimised for quantum error correction workflows. You will also help to develop optimisations for the compiler infrastructure.

Your work will involve both **theoretical understanding**of quantum error correction and **practical knowledge**of hardware-specific constraints in various quantum computing architectures.

**Key Responsibilities**:

- **Design and implement**components of Loom’s compiler toolchain, from logical gate representations to hardware-ready code.
- **Integrate program definitions**of logical gates with lower-level machine dialects, including MLIR, QIR, and QASM.
- Collaborate with QEC and hardware specialists to incorporate hardware-specific optimisations.
- Ensure compiler passes are modular, maintainable, and performant.
- Work on **cross-layer integration**, from quantum error correction abstractions down to hardware execution layers.
- Maintain documentation, tests, and developer guides for compiler components.

**Required Qualifications**:

- Strong background in **compiler development**or programming language theory.
- Familiarity with **quantum computing**concepts, particularly **quantum error correction**.
- Experience with **low-level compiler infrastructures**and machine dialects (MLIR, QIR, QASM, LLVM-based frameworks).
- Proficiency in **Python**and experience with **C++**for performance-critical components.
- Experience with version control tools ( **Git**) and collaborative software development workflows.

**Preferred Qualifications**:

- Hands-on experience with **quantum hardware toolchains**or simulators.
- Familiarity with multiple quantum computing architectures (superconducting, trapped-ion, photonic, etc.).
- Contributions to **open-source compiler or quantum computing projects**.

Understanding of **code generation and optimisation techniques**for heterogeneous hardware.
