Reports to: Head of Solutions Architecture
Job type: Full Time
Location: Central London, Hybrid
About Us
ORCA Computing (“ORCA”) is at the forefront of a new era in high-performance computing, developing full-stack photonic quantum systems designed to transform how organisations tackle machine learning, generative AI, and complex optimisation challenges. Headquartered in London, ORCA has delivered eleven on-premises quantum computers worldwide – demonstrating that its technology is not theoretical but already delivering real world results.
At the core of ORCA’s innovation is its hybrid quantum-classical architecture, engineered for seamless integration into existing AI and HPC infrastructure. Its current PT-2 system, a rack-mounted quantum computer, connects directly to GPU clusters via NVIDIA’s CUDA-Q platform, enabling accelerated AI workloads with significantly lower energy consumption than traditional silicon-based systems. Backed by a strong portfolio of patent families spanning photonic integrated circuits, quantum memory, and multiplexing technologies, ORCA is enabling enterprises, research institutions, and HPC operators to unlock new levels of performance, efficiency, and scalability.
As ORCA prepares to launch its next-generation PT-3 system, the company is entering a pivotal phase of growth and technological advancement. Its solutions are already being embedded into generative AI pipelines, delivering measurable improvements in model performance, while also addressing the rising energy demands of large-scale AI adoption. With a focus on practical deployment and a clear roadmap to fault-tolerant quantum computing, ORCA is leading the development and deployment of quantum technology, providing a commercially viable path to the future of computing.
What you will do:
- Deliver partner- and customer-facing content
You will work with colleagues in the ORCA Applications team to design and build technical content (including live demonstrations) that showcase ORCA’s capabilities in hybrid quantum-classical applications. You will own and deliver customer-ready demos running in HPC environments, running these live with customers (remote and onsite) and adapting them dynamically to technical discussions.
- Define solution architectures and technical blueprints
You will own end-to-end solution architectures for customer and partner use cases, working across internal and external teams, covering data pipelines, model workflows, compute environments and integration with ORCA systems.
- Shape and qualify customer opportunities
You will work with commercial teams to translate customer problems into structured technical approaches, defining feasibility, success criteria and resource requirements before projects move into delivery.
- Define and structure proof-of-concept engagements
You will design PoC approaches that test real customer value, balancing speed, technical rigour and commercial relevance, and ensuring alignment between customer expectations and ORCA capabilities.
- Contribute to technical marketing and GTM
You will support the creation of technically credible content by translating real architectures, demos and results into material usable by marketing, analysts and sales teams.
- Act as a bridge between teams
You will work across product, applications, marketing and commercial teams to ensure that partner- and customer-facing solutions are both technically valid and commercially impactful, and providing feedback from your partner and customer projects into the ORCA product roadmap.
What you will bring- required
- Pre-sales experience (deep-tech or high-tech)
- Experience working directly with enterprise and industry customers to deliver complex technology solutions
- Exposure to industrial applications in one or more of: chemistry, materials science, pharmaceuticals, energy, telecommunications, transportation, logistics, finance and defence
- Ability to design and communicate solution architectures and system diagrams clearly
- Proven ability to build and operate technical demos, prototypes or PoCs, including presenting them to technical stakeholders
- Experience with AI/ML, HPC, distributed systems, or scientific computing environments, including an understanding of performance, scaling and system architecture
- Strong programming skills in Python, with familiarity with ML frameworks and development workflows
- Experience with MLOps or production-oriented workflows, including environment management, reproducibility and deployment considerations
Nice to have
- Experience training or optimizing ML systems
- Experience solving optimisation / MILP problems
- Exposure to quantum computing
- Experience working for or with deep-tech startups
Who we are looking for:
- You have strong commercial acumen, understanding customer and partner commercial drivers and how technical decisions affect timelines, business outcomes and deal progression
- You are comfortable working at the boundary between technical depth and customer/partner engagement, able to move between detailed discussions with engineers and high-level problem framing
- You can translate complex technical systems into clear, structured explanations without oversimplifying or losing credibility
- You operate effectively in ambiguous, fast-moving environments, making progress without complete information
- You take ownership end-to-end, from initial problem definition through to demo delivery and customer validation
Why join us
Joining ORCA Computing offers the opportunity to work at the forefront of quantum technology, where innovation is already delivering real-world impact. Across commercial, operational, and product roles, you’ll collaborate with multidisciplinary teams to bring advanced quantum systems to market and help integrate quantum capabilities into modern AI and data centre ecosystems.
ORCA provides a rare chance to contribute to a pivotal moment in the evolution of computing. With a culture built on ownership, collaboration, and ambition, the company empowers individuals to solve complex challenges and shape how next-generation quantum technologies are developed, deployed, and scaled across industries – driving a more efficient and powerful future for AI and compute.
