## Job description

We are looking for a dedicated Quantum Error Correction (QEC) Architect to join the Equal1 team. This pivotal role will drive the research and development of error correction codes and logical circuit schemes tailored to silicon spin qubits.

As a Senior QEC Scientist / QEC Lead, you will lead the technical effort to design, evaluate, and evolve QEC architectures, translating theory into practical, hardware-aware approaches that support Equal1’s roadmap to scalable fault-tolerant quantum computing.

## MAIN DUTIES AND RESPONSIBILITIES

- Lead the efforts to implement quantum error correction protocols for Equal1 silicon spin QSoC technology platform.
- Designing and modifying error correcting codes, logical qubit schemes, and decoding algorithms suitable for large scale arrays of silicon spin qubits
- Specify the minimal requirements for our physical qubits to go beyond breakeven for various codes, and guide future qubit topology to facilitate error correction schemes.
- Conduct research and development to improve the efficiency and effectiveness of Equal1’s fault-tolerant quantum computing systems, and stay up-to-date with the latest developments and trends in the field.
- Develop and maintain technical documentation and collateral, including design specifications and test plans, and technical manuals.
- Simulate using appropriate noise models, quantum error correction codes, and fault-tolerant computations.
- Collaborate with other technical professionals across Equal1 and external collaborators to ensure that fault-tolerant systems are integrated effectively into the overall quantum computing architecture.
- Integrate with the Algorithms and Theory teams to develop new error correcting codes and implement algorithms on fault-tolerant error correction codes.
- Disseminate information and results internally and externally through internal seminars and publications in international journals and conferences.

## EXPERIENCE AND QUALIFICATIONS

- Comprehensive understanding of fault-tolerant quantum computing, with experience in the following areas: quantum error-correction, decoding, logical gate design, implementation of non-Clifford gates, lattice surgery, code switching etc.
- At least 5 years of relevant experience in academia or industry research in quantum error correction.
- Experience working with cross-functional teams, including engineering, algorithm, software, and measurement teams.
- Experience implementing quantum error correction solutions.
- Strong problem-solving and analytical skills, with the ability to design and develop complex fault-tolerant systems effectively.
- Strong communication and interpersonal skills, with the ability to effectively collaborate with quantum engineers, scientists, and other technical professionals.
- Experience in developing and maintaining technical documentation, including design specifications, test plans, and user manuals.
- Competence in programming using Python (or similar).
- PhD in a relevant field (e.g. Quantum Computing, Physics, Math, Computer Science) or Postdoc/industry experience in quantum error correction.
- A proven track record of relevant achievements (publication, preprints, public code).

## About Equal1

## Company Overview
- **One-liner**: Equal1 builds the world's first rack-mounted silicon quantum computers designed to deploy alongside classical CPUs and GPUs in standard data center infrastructure.
- **Entity Type**: Private (Series A, last raised $60M in January 2026)
- **Headquarters**: Dublin 4, Ireland (with offices in Fremont, CA; Delft, Netherlands; Sherbrooke, Canada; Timișoara, Romania)
- **Founded**: 2017
- **Founders**: Dirk Leipold (President & Co-Founder), R. Bogdan Staszewski (Co-Founder)

## Core Business
- **Primary Industry**: Quantum Computing / Nanotechnology / High-Performance Computing
- **Target Customers**: Enterprise and government data centers, HPC clusters, AI labs, defense and aerospace organizations (current customer includes the European Space Agency)
- **Mission Statement**: "Quantum will not deliver from the lab. It delivers when it becomes deployable: infrastructure that can be bought, run, scaled and trusted inside high-performance compute environments."

## Products & Services
- **Equal1 RacQ**: A rack-mounted silicon quantum computer that fits into a standard server rack with standard power and cooling. It runs alongside existing CPU/GPU infrastructure and supports hybrid quantum-classical workloads. Currently shipping to customers.
- **UnityQ**: The silicon quantum processor (QSoC - Quantum System-on-Chip) built in standard CMOS foundries. Each generation adds more qubits, higher fidelity, and exponential compute within the same rack footprint.
- **Quantum Solutions**: Capabilities for optimization (logistics, portfolio, scheduling), simulation (molecular systems, materials science), Monte Carlo (risk, pricing, modeling), and Quantum AI (training paths beyond classical scaling).

## Market Standing
- **Total Funding**: $106.5M across 12 rounds (last round: $60M in January 2026 led by Ireland Strategic Investment Fund)
- **Valuation**: Not publicly disclosed
- **Notable Investors**: Ireland Strategic Investment Fund, Matterwave Ventures, Atlantic Bridge, Enterprise Ireland, Elkstone Partners, EIC Fund
- **Key Partnership**: Signed a deal with **Nvidia** (September 2024) for hybrid supercomputer and quantum systems
- **Growth Signals**: 
  - RacQ already shipping to customers including the **European Space Agency**
  - Headcount growing 15.6% YoY (38 employees as of mid-2026)
  - Opened Dutch lab in 2024, partnered with TNO (Netherlands Organisation for Applied Scientific Research)
  - 34 patents filed in quantum information science
  - Multiple generations of silicon already proven

## Competitive Advantages
- **Silicon CMOS Advantage**: Unlike other qubit modalities (superconducting, ion trap, photonic) that require exotic manufacturing, Equal1 builds in standard silicon foundries — making their chips manufacturable, deployable, and upgradeable at scale.
- **Rack-Mounted Form Factor**: The only quantum computer that fits in a standard data center rack with standard power and cooling — no cryogenic infrastructure or dedicated quantum facility required.
- **Deployed Today, Not "Soon"**: RacQ is already shipping to paying customers, including a major space agency.
- **Nvidia Partnership**: Direct integration with the dominant AI/HPC ecosystem.

## Strategic Focus
- Scaling qubit count and fidelity with each UnityQ processor generation
- Deepening hybrid quantum-classical compute integration with Nvidia
- Expanding commercial deployments into optimization, simulation, and AI workloads
- Building out the software stack and framework engineering team
- Growing headcount in engineering, quantum error correction, device physics, and software roles

## Why Work Here
- **Work Environment**: "Hybrid by default" — employees work across offices in Ireland, Netherlands, US, Canada, and Romania
- **Culture**: Rated 5.0/5.0 on employer review sites (Work-Life: 5.0, Compensation: 5.0, Culture: 5.0, Career: 5.0)
- **Team**: Small (~38 people), highly technical (26% technical, 15% research), with talent from Intel (5 alumni), University College Dublin (7), TNO, Qualcomm, and Movidius
- **Impact**: You'd be building deployable quantum infrastructure that's already shipping — not just doing research
- **Career Growth**: Open roles include VP of Quantum Software Engineering, Quantum Error Correction Lead, Senior Verification Engineer, Spin Qubit Calibration Engineer — indicating serious scaling of the engineering team
- **Notable**: Employees have gone on to Stanford, PsiQuantum, Qualcomm — showing the team is deeply embedded in the quantum ecosystem
