INTRO Adsquare's mission is centered on: * Passion: Solving complex challenges with exceptional people, technology, and data. * Niche: Specializing in Location Intelligence for Programmatic Advertisers. Our work is guided by our core values, and we look for candidates who embody them: * Drive: Turning ambition into action that brings valuable outcomes. * Resilience: Adapting, persevering, and growing stronger through challenges. * No BS: Upholding honesty, transparency, and clear communication. * Humble: Valuing modesty and letting results speak for themselves. * Moral Compass: Acting with fairness, integrity, and respect. ABOUT THE TEAM Data sits at the heart of everything Adsquare does — it's the raw material behind every product we sell. This role leads our data sourcing function: a small, focused team responsible for the quality, legality, and strategic positioning of the data we bring in. You'll work hand-in-hand with Product, Legal, and Engineering, and grow the function as Adsquare scales. YOUR MISSION Data is our product. You'll own the data we bring in — what we source, on what terms, to what standard — and grow that into a strategic function as Adsquare scales. A builder's role: you'll lead a small team today and shape what the function becomes. YOUR PROFILE * 6+ years in data acquisition, data partnerships, or strategic partnerships within adtech, martech, or the wider data ecosystem — with real depth, not just deal volume. * A track record of both sourcing strategy and execution: deciding what data matters, then securing it on good terms. * Direct experience negotiating and managing data partnerships, ideally across multiple markets. * Deep grounding in privacy and compliance — GDPR, CCPA, consent frameworks, privacy-enhancing technologies. * Strong analytical instinct — able to evaluate data on quality, scale, coverage, and financial viability, not just take a supplier's word for it. * A builder — comfortable shaping a function rather than inheriting a finished one, and comfortable in ambiguity. * Direct, low-ego, high-integrity. Fits how we work: Drive, Resilience, No BS, Humility, Moral Compass. WHAT YOU WILL DO * Define and execute Adsquare's data sourcing strategy — what to acquire, build, or partner for, and the business case behind it. * Identify, evaluate, and negotiate terms with global and local data providers (mobile apps, SDK networks, retail media, telcos, first-party data owners). * Set data quality standards and the monitoring to enforce them — catching problems at the provider level, not when a client does. * Own the legal and privacy posture on sourced data alongside Legal — consent, GDPR/CCPA and equivalents, licensing compliance. * Manage existing data-partner relationships — value, optimisation, renewals. * Partner closely with Product and Engineering on technical onboarding and evaluation of new data streams. * Build and grow the team as the function scales. NICE TO HAVE * Strong knowledge of programmatic advertising, location data, and industry identifiers. * Enough technical fluency (APIs, data formats, cloud data transfer) to challenge and guide credibly. * Experience intiating first-party data collection or a sourcing capability in a new market. WHY US? * Hybrid + remote from anywhere up to 3 months/year * €1,200 yearly learning & development budget * 30 vacation days * Urban Sports Club membership * Company pension scheme * Latest hardware provided * Regular team & company events SALARY RANGE (ANNUAL ON-TARGET EARNINGS) €90,000–€110,000 (base salary + performance bonus), depending on experience. RECRUITING PROCESS We value your time and aim to provide a transparent and efficient recruitment experience. * Values-fit interview - 30 min * Hiring Managers interview - 60 min * Case study presentation - 90 min * Reference check * Offer WORK MODEL Hybrid DESIRED START DATE As soon as possible

We are disrupting a massive industry bogged down by legacy systems and manual work. This is where you come in. We build the intelligent software and automation that gives us a decisive edge, allowing us to operate at a scale and efficiency our competitors can't match. We are looking for a Staff Engineer - Full Stack (f/m/d) to serve as a strategic technical leader. In this role, you will not just solve the problems we hand you; you will identify the problems we should be solving. You will report to a Domain Lead and act as a technically-focused peer, helping to define the vision for our platform and the AI strategies that will differentiate us in the market. IF YOU ENJOY THIS * Drive cross-team technical strategy. You will architect the high-level systems that connect our customer apps, internal tools, and data backbone, ensuring we build for long-term scalability and resilience. * Operate with high-level autonomy. You will translate vague business objectives into concrete technical roadmaps, proactively identifying opportunities for impact without needing a Product Manager to define every step. * Lead our AI Engineering evolution. You will co-design the patterns for integrating LLMs into our code - handling reliability, cost, and evaluation - while demonstrating to the wider organization how to build AI-native software. * Act as a force multiplier. You will elevate the entire department by removing developer bottlenecks, mentoring engineers, and championing AI-augmented workflows. * Bridge the gap between Business and Tech. You will partner with leadership to navigate ambiguity, translating complex architectural trade-offs into business value and leading large-scale initiatives to delivery.

You are great in Python and Node.js/TypeScript. You understand backend and frontend. You can reason about data flows and architecture, and you can build them too. * "Manager of One": You are self-directed. If dropped into ambiguity, you create clarity. You can effectively manage your time between coding, designing, and communicating without needing constant oversight. * Pragmatic: You avoid over-engineering. You understand that "boring technology" is often best, but you know exactly when to spend innovation tokens (specifically on AI and Cloud scalability). * Great Communicator: You write clear, persuasive technical documents (RFCs, ADRs). You can lead a room of engineers to a consensus even when opinions differ. You can articulate the business implications of technology in a room full of VPs. Bonus points * Production AI: Experience deploying LLMs in production (managing context windows, prompt engineering, vector databases, and evaluation frameworks). * Event-Driven Systems: Deep experience with asynchronous architectural patterns and specific systems like RabbitMQ, Google Pub/Sub and Kafka. * Legacy Migration: Experience strangling a monolith or migrating legacy systems to modern cloud-native architectures without downtime. * Familiarity with Sales: Experience writing software that enables Sales teams (ex: CRM, scheduling). * A passion for climate tech. You're motivated by our mission to decarbonize homes and are excited to apply your skills to a problem that matters. WHAT WE HAVE TO OFFER * In this role, you can expect an attractive compensation package starting from €100.000 * Join a team of Product Managers, Software Engineers, Designers, Data and Salesforce people who are excellent in their craft and are happy to share their knowledge and help you grow alongside them * Our team is using the latest frameworks and is working with a modern tech stack to build powerful products for our customers, craftspeople, and internal teams * Boost your skills with a dedicated annual learning budget to spend on conferences, courses or books * Choose your own AI coding companion – we provide you with the license for the AI model or assistant of your choice * We offer a challenge with purpose - the better our tech, the more people will live climate-neutral and the better the world becomes for future generations * We offer a fantastic culture in the tech team and beyond * Modern office in the heart of Berlin * Work from home - up to 3 days a week * You receive an Urban Sports Club membership & nilo.health membership * You can lease a job bike or bring your dog one day/week * Corporate Benefits at more than 100 partners * 20% employer contribution to your pension and disability insurance ABOUT US Every application is welcome here - regardless of gender, nationality, ethnic and social background, religion, ideology, disability, age, sexual orientation or identity.

Today, our proprietary software enables 800 thermondinos to scale the heating transition in Germany. But we want more. We want to enable fully digitized and smooth customer journey ensuring that all processes are coming together: commercial funnel, procurement, product, supply chain, project management, finance, dispatch, HR planning as well as customer facing offerings for maintenance and home energy management.
