HI, WE’RE BACK MARKET. We’re here to help make tech reliable, affordable, and better than new. We're a global marketplace for refurbished devices, helping lower our collective environmental impact by providing trustworthy, affordable tech with 92% less carbon emissions than new. Yep, you read that right. Turns out refurbished tech is way better for the planet than new. In fact, With every device purchased on Back Market, our positive impact on the planet grows. From our Customer Care representatives to our software engineer, every individual at Back Market cuts the planet — and consumers — a break. Our mission is simple: to do more with what we already have. Are you ready to join us? Back Market runs on data. Every insight we surface, every model we build, every anomaly we catch is a step toward making refurbished tech the world's obvious choice — not the alternative. Our Data, Analytics & Insights team is expanding, and we're opening three analytical ownership roles at once: Strategy & Commercial, Customer Care, and Shipping & Logistics. One application. One process. We'll find the best fit together. Wherever you land, you'll own a domain end-to-end — from the data model to the boardroom decision. These aren't reporting roles. They're roles where your analytical judgment drives real business direction. YOUR MISSION (IF YOU ACCEPT IT) 🥇 Depending on which domain becomes your home, here's what you'll own: Strategy & Commercial Analytics * Monitor and diagnose commercial performance for Central Europe — weekly, proactively, with course-correction plans ready before anyone asks * Contribute to 12M+ sales forecasting and P&L budgeting, translating initiative impacts into tactical recommendations when the trajectory drifts * Build data models and tooling that surface actionable pricing signals to the commercial and revenue teams * Enable self-service access to pricing and supply health data across the organisation Across all domains, you'll: * Own your analytical domain end-to-end — from data model to decision, you're the go-to person * Partner directly with senior leadership — not just delivering analyses, but shaping the questions we ask * At Staff level: mentor junior analysts and raise the bar for how the team approaches problems 🛠️ Tech Stack What the team works with day-to-day: * Data Warehouse: Google BigQuery * Transformation: dbt * Visualisation & BI: Omni, Amplitude * Languages: SQL (essential), Python (very useful) * Care tooling: Zendesk, Intercom * Experimentation: A/B testing and incrementality frameworks * YOU ARE IN THE RIGHT PLACE IF ⭐ You have: * Strong SQL proficiency and comfort working with large, complex datasets — you can build the query and explain what the result means for the business in the same breath * A track record of owning analytical problem spaces end-to-end — outcomes that shaped business direction, not just answered one-off questions * A rigorous analytical mindset: you understand causal vs. correlational reasoning, know the limits of your data, and can design a measurement framework from scratch * Excellent communication and storytelling skills — you distil complex, multi-variable analyses into crisp narratives that move senior stakeholders to act * Experience in business analytics, commercial strategy, or a customer-facing operations domain (marketplace, e-commerce, logistics, or similar) * 5+ years of experience in data analytics, or equivalent hands-on analytical ownership Nice to have: * Python proficiency for statistical work, modelling, or analytical automation * Domain familiarity: pricing/revenue management for Commercial; care platform experience (Zendesk, Intercom) for Care; logistics or carrier analytics for Shipping * Experience designing experiments in an operational context (A/B tests, holdouts, or incrementality measurement) Even if you don't tick every box, we encourage you to apply. We value diverse analytical backgrounds and unconventional paths to expertise. WHY SHOULD YOU JOIN US ? ✌🏼 At Back Market, we’re committed to hiring and supporting diverse teams of people from all backgrounds, experiences, and perspectives — it’s one of the reasons we’re such a high-scoring certified B Corp company (93.2).

If reasonable accommodations are needed for the interview process, please do not hesitate to discuss this with the Talent Acquisition Team.
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! The team: The Pulse Team is responsible for developing the low-level software stack that controls the hardware systems enabling our physicists to conduct cutting-edge quantum experiments, and eventually be at the core of our quantum computer. About the role: As a Senior Software Engineer, you will play a pivotal role in designing, developing, and maintaining robust, high-performance software solutions at the core of our technology. Acting as a technical leader within the team, you will drive architectural decisions, champion engineering best practices, and mentor junior engineers to support their professional growth. You will be in charge of developing the low level of our stack, as close as possible to our hardware. Your work will be central in bridging scientific R&D, data engineering, and production-grade platform design while enabling researchers and physicists to iterate rapidly without compromising reliability.
