Zusammenfassung

Alice & Bob, a quantum computing startup in France, seeks a Scientific Software Engineer to own and evolve the internal framework that turns quantum circuits into layouts and sends them to simulators. You’ll grow its component library, improve robustness, and enable large-scale chip design automation.

Join a diverse team building the first universal quantum computer. Strong Python skills and collaboration with hardware engineers are essential, with a flexible remote policy and competitive

Qualifikationen

• 5+ years of professional Python development with strong software engineering fundamentals (testing, packaging, versioning, CI/CD, code review).
• Experience building and maintaining a library or framework used by other engineers and well-documented APIs.
• Comfort with computational geometry or CAD/layout data, or eagerness to learn quickly.
• Ability to work closely with hardware engineers and translate their needs into software.
• Fluent English and excellent written and verbal communication skills.

Aufgaben

• Own and maintain the internal design backend API and qubit design framework: code quality, testing, CI, releases, documentation.
• Develop new parametric components and layout primitives with the chip designers who use them.
• Extend and harden the export pipeline to electromagnetic and circuit simulation tools.
• Build the automation layer for large-scale, hierarchical chip layouts in close partnership with our physical-design and scale-up engineers.
• Support internal users: onboarding, debugging, API design, and turning recurring pain points into features.

Jobbeschreibung

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 Mission

Every chip Alice & Bob builds starts as Python code. As we scale from tens of qubits to thousands, our chip-design software becomes the backbone of the entire design pipeline, and it has to support chips that could never be drawn by hand.

About the Role

As a Scientific Software Engineer in the Design and Implementation team, you’ll own the internal framework our engineers use to turn a quantum circuit into a layout and send it to electromagnetic and circuit simulators. You’ll keep it robust and fast, grow its component library, and build the automation our layout and scale-up engineers need to design large chips.

Responsibilities

• Own and maintain the internal design backend API and qubit design framework: code quality, testing, CI, releases, documentation
• Develop new parametric components and layout primitives with the chip designers who use them
• Extend and harden the export pipeline to electromagnetic and circuit simulation tools
• Build the automation layer for large-scale, hierarchical chip layouts in close partnership with our physical-design and scale-up engineers
• Support internal users: onboarding, debugging, API design, and turning recurring pain points into features

Requirements

• 5+ years of professional Python development, with strong software engineering fundamentals: testing, packaging, versioning, CI/CD, code review
• Solid experience building and maintaining a library or framework used by other engineers, and a taste for clean, well-documented APIs
• Comfort with computational geometry or CAD/layout data (GDSII, polygons, transformations) — or eagerness to learn it fast
• Ability to work closely with hardware engineers and translate their needs into software
• Fluent English and excellent written and verbal communication skills

Nice to have:

• Experience with gdstk, gdsfactory, KLayout, or other layout tooling
• Familiarity with electromagnetic simulation tools (HFSS/AEDT, Palace) or circuit simulators
• Background in superconducting circuits, RF/microwave engineering, or semiconductor design automation (EDA)

Recruitment Process

• Screening Call with Grace, Talent Acquisition Specialist (30 min)
• Hiring Manager Interview with Felix (45 min)
• Technical Interview/Presentation with the Team (120 min)
• Leadership Team Interview (30 min)Fit Interview (45 min)
• Reference check
