Senior Applied AI 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:

The Workflow team leverages software, AI and automation to improve the efficiency of the R&D processes of Alice & Bob.

As a Senior Applied AI Engineer in this team, you will design, deliver, and maintain high-quality, scalable and robust AI-based solutions to solve complex problems encountered by R&D teams and improve their efficiency. You’ll act as an individual contributor and technical leader to key projects dealing with both simulation and real-life execution of quantum experiments. You’ll work with elite researchers and engineers across Alice & Bob.

You don’t need to be a physics expert to succeed in this position. If you’re curious, motivated, and a fast learner, we’ll teach you everything you need to communicate efficiently with our scientists, and make a positive impact through your work.

Responsibilities:

Lead projects from conception to delivery autonomously, navigating ambiguity while meeting timelines.

Own the design, development, maintenance, and delivery of AI-powered features, tools, or workflows, in partnership with Software Engineers.

Evaluate, benchmark, and deploy LLMs and agentic AI systems for R&D use cases, selecting appropriate models, architectures, and evaluation methodologies.

Implement and promote best practices in LLMOps and DevOps (e.g., model versioning, evaluation pipelines, CI/CD, observability, infrastructure as code).

Lead design and code reviews for AI-related projects, and provide actionable feedback to peers.

Collaborate efficiently with colleagues of various backgrounds (researchers, engineers, product managers…) to deeply understand their needs and proactively suggest AI-based workflows to make them more efficient.

Mentor and support more junior engineers in their technical growth and onboarding.

Participate in the continuous improvement of the team's processes.

Requirements:

5+ years of professional software engineering experience, including at least 2 years focused on AI/ML systems in production environments (LLMs, agentic pipelines, RAG, or similar).

Strong software engineering skills, with a track record of shipping reliable, maintainable code in a team setting (code reviews, CI/CD, testing, observability).

Hands-on experience evaluating, fine-tuning, and deploying LLMs (prompt engineering, evaluation frameworks, and model selection).

Familiarity with LLMOps practices: model versioning, evaluation pipelines, monitoring/tracing in production.

Ability to communicate and work efficiently with colleagues from various backgrounds (researchers, engineers, product managers), and to translate their needs into actionable technical items.

Professional-level English proficiency, both written and spoken.

Nice to have :

Experience working in a scientific or R&D-heavy organization.

Experience with agentic AI frameworks (e.g., LangChain).

Exposure to workflow automation tools or data pipelines (e.g., Airflow, Prefect).

Experience with infrastructure-as-code and a cloud platform (e.g., AWS, GCP, Azure).
