Senior Data Engineer

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 250+ brilliant minds from over 35 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 our GCP Data Platform, reporting directly to the Data Platform Lead. You will own the full data lifecycle-from building our data lake and architecting ingestion pipelines for quantum computing experiments, to powering company-wide analytics and ML. In this role, you will drive platform infrastructure, data governance, quality, and engineering 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

Recruitment Process:

• Screening call with Doriane (30 min)
• Hiring Manager Interview (60 min)
• Technical Interview with the Team (90 min)
• Leadership Interview (30 min)
• Fit Interview (30 min)
• Reference check

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

- Subsidized membership with Urban Sports Club

- Mental health support with moka.care

- 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
