Alice & Bob is developing the first universal, fault-tolerant quantum computer to solve the world’s hardest problems.
The quantum computer we envision building is based on a new kind of superconducting qubit: the Schrödinger cat qubit 🐈⬛. In comparison to other superconducting platforms, cat qubits have the astonishing ability to implement quantum error correction autonomously!
We're a diverse team of 200+ brilliant minds from over 30 countries united by a single goal: to revolutionise computing with a practical fault-tolerant quantum machine. Are you ready to take on unprecedented challenges and contribute to revolutionising technology? Join us, and let's shape the future of quantum computing together!
About the Role:
As a Senior Data Engineer, you will help build and scale a reliable Data Platform on Google Cloud Platform. Reporting to the Data Platform Lead, you will design and operate the infrastructure powering analytics, reporting, and machine learning.Your role covers the full data lifecycle: building the company’s data lake, designing ingestion architectures for quantum computing experiments, and enabling teams across the organization with reliable, well-governed data pipelines. You will also drive data quality, documentation, and platform best practices
### Main Responsibilities:
Data Platform & Lakehouse
Design and operate a scalable GCP data lake (storage, partitioning, lifecycle, governance).
Build ELT pipelines from APIs, event streams, internal systems, and scientific instruments.
Develop lakehouse architectures using GCP services such as BigQuery, Composer/Airflow, Dataflow, Dataproc, Pub/Sub, and GCS.
Work with open table formats such as Apache Iceberg, Delta Lake, or Hudi.
Quantum Experiment Data Ingestion
Co-design ingestion pipelines for quantum computing experiment data alongside physicists and hardware engineers.
Handle high-throughput scientific data, heterogeneous formats, metadata management, and traceability.
Define scalable metadata standards and schemas.
Cross-Team Enablement
Support engineering teams in designing reliable and maintainable data pipelines.
Create reusable patterns, standards, and best practices.
Mentor engineers on orchestration, data modeling, and testing.
Data Quality & Governance
Implement validation, monitoring, data contracts, and governance standards.
Own the data catalog and lineage documentation.
Partner with analysts, ML engineers, and stakeholders to deliver trusted datasets and optimize BigQuery performance/costs.
### Profile:
5+ years of experience in Data Engineering and production-scale data platforms
Strong expertise in SQL, Python, and GCP data services (BigQuery, Airflow, GCS, Pub/Sub)
Experience with distributed processing tools and modern lakehouse technologies (Spark, Iceberg, Delta Lake, Hudi)
Solid understanding of data modeling, orchestration, CI/CD, and data governance
Experience with scientific, hardware, or experimental data pipelines is a plus
Strong communication skills, analytical mindset, and ability to mentor cross-functional teams
Fluent English required; experience in deeptech or quantum environments is a plus
### Benefits:
- Our success is your success: own it with our BSPCE plan
- Direct IP Compensation: Earn substantial bonuses for driving the core patents that define our quantum architecture.
- Flexible remote policy, up to 40 % a month
- A Parental plan including additional benefits such as crèche support or additional days-off to take care of under 12 years old children
- 25-day vacation policy (as per French law) + RTT
- Half of transportation cost coverage (as per French law), or yearly allowance for the die-hard bicycle users
- Competitive health coverage, with Alan.
- Meal vouchers with Swile, as well as access to a fully equipped and regularly stocked kitchen
- French language courses covered by the company for those interested
