Qilimanjaro Quantum Tech is a Barcelona-based quantum computing company buildingfull-stack analog quantum computerson superconducting fluxonium qubits. Founded in 2019 as a spin-off from the Barcelona Supercomputing Center (BSC), the University of Barcelona (UB) and the Institute of High-Energy Physics (IFAE), the company exists to make quantum computing useful in the near term, rather than in a distant error-corrected future.Qilimanjaro designs, builds and operates the complete stack: the quantum hardware, the control layer, and the software that orchestrates it.What we are looking forWe are looking for a Team Lead to manage and develop the software engineers who build the control layer for our quantum hardware. You will combine direct people management and delivery planning with hands‑on expertise in quantum hardware and the software used to control and operate it. You are also comfortable leading a team that develops with AI coding agents or similar tools.You will report to the Head of Software Division and work alongside a dedicated Tech Lead. You will own the team’s people management; capacity and execution.The Tech Lead retains responsibility for department technical direction and architecture. The role includes technical contribution, with time allocated according to the management load.Set clear expectations, run regular one-to-ones, give actionable feedback and support performance and career reviews with People.Build the team’s capacity plan, coordinate execution and remove blockers across product development and research work.Agree feasible delivery plans with the relevant Product Owners, making dependencies, scope choices and resource constraints explicit.Partner with the Tech Lead on technical risk, architecture and the research backlog, ensuring difficult decisions have clear ownership and time for validation.Contribute your quantum hardware expertise to control and measurement workflows, and coach engineers on the relationship between software behavior, physical systems and experimental evidence.Coordinate interfaces and handovers with engineers developing software development kits, firmware,



quantum hardware and operating infrastructure.Ensure delivery plans include software verification and the appropriate hardware and scientific validation, with named acceptance owners.Lead the team's use of AI coding agents and similar tools. Make sure that what the team builds with AI is verified.Support hiring and onboarding with the Head of Division and People, and distribute knowledge across the team.Proven direct people-management experience, including feedback, development, performance conversations and team planning.Demonstrated hands‑on expertise in quantum hardware, including its control, operation or measurement, and the ability to connect software and control choices to physical behavior and experimental validation.Strong software engineering knowledge and practical experience with low-level control or hardware/software integration.Evidence of delivering complex technical work while managing capacity, dependencies and uncertainty.Ability to collaborate with an established Tech Lead and distinguish technical authority, line management and product ownership.Ability to explain technical risk and give clear, constructive feedback to engineers and stakeholders.Hands‑on experience developing software with AI coding agents in your own work, with the judgment to verify what they produce, and the commitment to lead a team that develops this way.Experience with superconducting quantum systems and their control or calibration workflows.Experience with instrumentation, timing and synchronization constraints, reproducibility or experimental automation.Experience leading a small technical team with both product delivery and R&D responsibilities.Experience leading a team's adoption of AI‑assisted engineering,



with measured effects on quality and delivery.Familiarity with Qilimanjaro's libraries and control stack. Product‑specific knowledge can be learned on the job.A relevant scientific or engineering education, or equivalent applied experience. A particular degree title is not a substitute for demonstrated competence.Diversity and InclusionAt Qilimanjaro, inclusion and equal opportunities are part of our people‑centric value. We are committed to creating a workplace where everyone feels valued and empowered to contribute, learn, and belong.We offer:A unique opportunity to work on real superconducting quantum hardwareStrong mentorship and technical growthCobee flexible compensation(transportation, meals, and childcare support)Versátil working hoursYou will:Get the opportunity to build something amazing and unique, something that hasn't been done beforeWork on ground-breaking projects and possibly solve massive challenges on a global scaleBe at the intersection of research and industry, where biggest innovations happenMake an enormous impact in a dynamic scale‑up rather than being a small cog in a big machineWork with super smart, knowledgeable and yet, very friendly people in Barcelona, one of the best cities in the world (picture a lot of sun, amazing food and friendly locals)Get to be part of a start-up where growth on a company and individual level is the defaultGDPR (General Data Protection Regulation):DATA CONTROLLER: QILIMANJARO QUANTUM TECH S.L., B67429670, Carrer de Veneçuela, 74, 08019 Barcelona (BARCELONA), Data Protection Officer: qilimanjaro@delegado- datos.Com.PURPOSES: Participation in recruitment processes and reference verification.LEGAL BASIS: Implementation of pre-contractual measures.DISCLOSURES: None are an ticipated.DATA RETENTION: For the duration of the selection process.RIGHTS: You may exercise your rights of access, rectification, erasure, restriction, and data portability with the data controller.
