Qblox is looking for a Junior Quantum Success Engineer to join our Quantum Success Engineering (QSE) team. We specialise in quantum control stacks that generate the analogue signals required for the control and readout of quantum bits. The QSE team ensures customer success through technical support, onboarding, and acting as the voice of the customer back into Qblox's product development.
This is an entry-level role designed for someone eager to grow their technical and customer-facing skills in a cutting-edge quantum computing environment, with a clear path toward specialised technical support.
What You'll Do
- Customer Support: Serve as the first point of contact across support channels (helpdesk, email, etc.), triaging incoming requests and resolving common technical queries in a timely and professional manner.
- Onboarding Assistance: Support customers during installation and initial setup of Qblox hardware, helping them get up and running quickly.
- Troubleshooting: Perform basic diagnostics and troubleshooting, escalating more complex issues to senior QSE engineers while shadowing their approach to build your own expertise.
- Documentation: Maintain accurate records of support interactions and contribute to internal knowledge bases and FAQs.
- Feedback Relay: Capture and communicate customer feedback to the broader QSE team to help inform product improvements.
Growth Path
This role is structured to develop into a more specialised L2 technical support position, including premium and advanced customer support, as you build expertise in Qblox's hardware and the broader quantum control stack.
Your Profile
- A Bachelor's or Master's degree in physics, electrical engineering, or a related field. Hands-on experience with microwave/RF experiments is a plus.
- Familiarity with Python programming.
- Strong communication skills — able to explain technical concepts clearly and respond to customers with patience and professionalism.
- A problem-solving mindset and genuine curiosity about quantum technology.
- Fluency in professional English.

TECHNICAL & MARKET ANALYSIS | Appended by Quantum.Jobs
The emergence of specialized technical support tiers within the quantum hardware ecosystem reflects a critical shift from exploratory research to engineering-driven reliability. As quantum control stacks reach higher levels of complexity, the structural necessity for professionalized success engineering becomes a primary determinant of user-side uptime and experimental reproducibility. This role type serves as the vital translation layer between advanced pulse-generation hardware and the diverse end-user base attempting to scale qubit operations. By stabilizing the interface between complex classical instrumentation and quantum processing units, these personnel mitigate the high friction associated with early-stage systems integration. This foundational enablement is essential for a market moving toward utility-scale systems, where consistent hardware performance is mandatory for commercial viability. Ongoing ecosystem initiatives aim to accelerate readiness for practical quantum applications by securing the talent pipeline necessary for long-term operational sustainability.
The quantum computing value chain is currently navigating a pivotal transition from "Quantum for Metrology" toward the industrialization of quantum processors. This shift introduces significant pressures for standardization, reliability, and supply-chain formation, particularly within the hardware control and readout layer. While much of the industry's historical focus has centered on PhD-level innovation, recent workforce intelligence indicates that a critical bottleneck is emerging in the "technical enablement" tier. This shortage of specialized personnel capable of managing the intersection of microwave engineering, digital signal processing, and customer-facing technical support poses a systemic risk to the scalability of global quantum hubs.
Within this landscape, the role of a success engineer acts as a prerequisite for both manufacturing yield and research reproducibility. As firms move from prototype development to pilot production, the ability to maintain stable control environments without service interruption becomes a strategic advantage. This is particularly relevant for companies like Qblox, where the integration of high-density control stacks requires a shared measurement language and systematic characterization methods. The stabilization of these customer environments is not merely a service function but a core component of the industry’s Technological Readiness Level (TRL) progression.
Furthermore, the macro-level trend toward hybrid classical-quantum cloud platforms demands that physical infrastructure operate with high availability. This necessitates a proactive approach to technical support that balances deep-tech troubleshooting with structured knowledge management. By bridging the gap between hardware development and practical application, these roles ensure that the increasing volume of global capital investment translates into measurable scientific and commercial outcomes rather than being stalled by technical complexity.
The capability architecture for this role type centers on the integration of radio frequency (RF) engineering principles with modern software automation frameworks. At the hardware-software interface, mastery of signal synthesis and cryogenic-qualified microwave chains is required to ensure the integrity of control pulses at millikelvin temperatures. These technical domains are critical for maintaining qubit coherence, as even minor misalignments in the signal chain can induce decoherence or gate errors. Success in this area relies on the ability to interpret complex diagnostics across diverse hardware modalities, from superconducting circuits to neutral atom traps.
Structural leverage is achieved through the coupling of Python-based automation with specialized instrument control protocols. This interoperability allows for the rapid deployment of calibration routines and performance benchmarking, which are essential for scaling system size without a linear increase in manual oversight. Furthermore, the role facilitates a cross-functional feedback loop where field-level performance data informs the architectural iteration of future control stacks. By standardizing the maintenance and onboarding processes for these systems, success engineers enable a level of operational reliability that allows research teams to focus exclusively on algorithmic breakthroughs.
