You'll take technical ownership of the data platform behind how we run the business: the pipelines, the warehouse, and the definitions behind the numbers our leadership team actually uses. You'll report to our Head of Engineering and work alongside a colleague who owns the business-facing side of data, plus our infrastructure and application engineers. This is a senior individual contributor role with no line management in either direction, roughly 70% hands-on building, 30% defining, documenting and explaining. ## Your Challenge and Opportunity in This Role JUPUS supports hundreds of law firms across Europe, and our customer base is growing roughly 4x a year. Our data platform has grown with it (ClickHouse, dbt, Python extract-load pipelines into an S3 data lake, orchestration in GitHub Actions) and it has grown fast. Your job is to make it trustworthy. That means modernising what already exists, making historical trends a record of what actually happened rather than a nightly re-derivation of it, and owning the definitions behind the metrics that reach our board. This is not a greenfield build, and it is not a maintenance seat. It is a real platform with real problems, and you would own it. Tasks - Own the data platform end to end: ingestion and the raw layer, the ClickHouse warehouse, and the dbt project on top of it. You're the person who can say whether a number is wrong or the pipeline is. - Make our numbers trustworthy: reliability, correctness, and a history that holds up, so that a trend is a record of what actually happened rather than a re-derivation of it. - Own the metrics the company runs on, starting with our customer health score- the definition, the denominator, the eligibility rules and the known limitations, not just the SQL underneath them. - Turn business questions into durable metrics: work directly with Customer Success, Sales, Product and leadership to understand what they're actually trying to decide, then build something defensible enough to decide on. - Keep cost and complexity in check as we grow: warehouse architecture, query cost, and the surfaces that deliver data into BI and our CRM. All of it gets harder as the customer base multiplies. - Set the standard for how data work is done here: one authoritative written definition per leadership-visible number, and the conventions that inform our Data function as it grows with us. ## Requirements Technical Expertise - Substantial experience in data engineering or analytics engineering, with production ownership of a warehouse and a transformation layer. We care more about evidence of ownership than about years served. - ClickHouse in production. - dbt at ownership level: incremental models, snapshots, tests, macros, CI/CD. Ideally you've inherited someone else's dbt project and left it better than you found it. - Python data engineering: EL tooling, S3, CI-based orchestration that you’ve owned end to end, with no platform team behind you. - Product event streams: PostHog, Amplitude, Segment, Mixpanel or similar. You understand how user-to-company identity and group association break, and what that does to every metric downstream. Judgement and Ownership - You have defined a business KPI end to end and defended it to non-technical people. This is the differentiator for us. An excellent engineer who takes requirements as given is not the right fit for this role. - Analytical rigour: cohorts, correct denominators, sample size stated before findings. You'll say "we can't tell yet, and here's exactly why" rather than produce a confident chart. - You act without waiting for a ticket, and you can name something you chose to stop doing. - You're comfortable in front of senior stakeholders, including C-level, and can hold a technical line without losing the room. Further Requirements - Located within CET +/-2. - Nice to have: BI tool administration (we use Metabase), CRM and billing systems as data sources, dlt specifically, GDPR-driven data deletion work, Grafana, German, or B2B SaaS and legal-tech domain experience. - Nice to have: you're used to non-technical colleagues querying data through AI tools, and you design for that. ## Benefits 🎯 Metric Ownership – Own a business-critical metric end to end, definition included — not just the pipeline that feeds it. 🛠️ A Real Platform – ClickHouse and dbt already in production, with genuine problems worth solving. No greenfield theatre, no maintenance seat. ⚡ Direct Access – A flat structure and a direct line to our Head of Engineering, CTO and CEO. No committee between you and a decision. 📈 Growth Stage – Roughly 4x customer growth a year at one of Europe's fastest-growing AI legal tech companies. 🏡 Fully Remote – Enjoy the flexibility of working from anywhere 💻 Top Equipment – State-of-the-art MacBook plus all the accessories you need 🏋️ Wellbeing Perks – Urban Sports Club membership to support your healthy lifestyle If you're excited about owning the numbers an AI startup runs on and delivering the data that guides us in our scaling journey, we'd love to hear from you. ## About JUPUS ## Company Overview - **One-liner**: JUPUS provides an AI-powered legal secretary platform that automates client intake, document generation, and communication for law firms. - **Entity Type**: Private (Series A – €13M raised) - **Headquarters**: Cologne, Germany - **Founded**: 2022 - **Founders**: René Fergen and Jannis Gebauer ## Core Business - **Primary industry**: Legal technology (AI software for law firms) - **Target customers**: B2B – solo practitioners, small to mid-size law firms, and larger practices in German-speaking Europe - **Mission or purpose statement**: Automate the client intake process from initial contact to complete file, reducing administrative load and enabling lawyers to focus on billable work. ## Products & Services - **JUPUS AI Chatbot**: An intelligent chatbot for law firm websites that captures visitor inquiries, asks for relevant information and documents, and converts 3x more visitors into formal requests. - **JUPUS Phone AI**: An AI answering machine that understands caller concerns, asks for key details, and never misses an important call. - **Online Appointment Booking**: A calendar widget synced with the firm’s calendar; clients reserve appointments and provide preliminary legal information before booking. - **Digital Questionnaires & Document Generation**: Automatically generates powers of attorney, fee agreements, and other legal documents from client-submitted information; supports digital signatures. - **Automated File Creation**: One-click creation of case files in the firm’s software, including all collected master data, documents, and communication history. - **Central Request Platform**: All inquiries (email, phone, website) are aggregated in a single dashboard with AI-powered summarisation and suggested replies. ## Market Standing - **Valuation/Market Cap**: Not disclosed (private company) - **Key Metric**: Total funding – €13M Series A (lead investor undisclosed in snippet; previous seed of €6.5M led by Acton Capital) [htgf.de](https://www.htgf.de/en/portfolio/htgffamily/jupus/) | Total funding approx. €20M (combining angel, pre-seed, seed, and Series A) - **Notable Investors**: Acton Capital (lead seed), HTGF (High-Tech Gründerfonds, lead pre-seed), plus multiple angel investors including Marcus Bez, Ingo Weber, Laura Wolfram [linkedin.com](https://de.linkedin.com/company/jupuslegal) - **Growth Signals**: Headcount grew 176% YoY to 59 employees; 20 active job postings (monthly job postings +17.6%); hundreds of law firms processing 200+ inquiries per day (as of May 2023) [htgf.de](https://www.htgf.de/en/portfolio/htgffamily/jupus/) | LinkedIn followers grew 129% YoY to 4,397 ## Competitive Advantages - **AI-first automation** that covers the entire client intake workflow – from chatbot to digital signature – not just a single piece of software. - **Full compliance** with GDPR, BRAO (German legal professional rules), and use of certified EU servers. - **30-minute setup** and immediate integration with 30+ law firm software systems (e.g., AnNoText, RA-Micro, DATEV). - **No training required** – platform is pre-configured with the firm’s own documents during onboarding. ## Strategic Focus - **Scaling sales and customer success** to capture the growing German legal-tech market (20 open positions in sales, onboarding, and customer success). - **Deepening AI capabilities** with the new Phone AI module and expanding conversational AI to handle more complex legal queries. - **Internationalisation** – small presence already established in the UK, Nigeria, and Spain; likely expansion beyond DACH region. ## Why Work Here - **Fast-growing startup** with 176% headcount growth and a clear product-market fit in a traditional industry ripe for disruption. - **Hybrid/office culture** – headquartered in Cologne (WeWork at Pilgrimstraße 6c) with a young, multidisciplinary team (engineering, product, sales, marketing). - **Strong technical team** – 11 engineers (16% of workforce) led by a Head of Engineering, with a Lead Product Designer and a Head of Product. - **Impactful work** – every employee directly contributes to reducing lawyers’ administrative burden and improving client experience. - **Transparent culture** – open job postings show heavy investment in go-to-market roles, indicating aggressive growth and career advancement opportunities. ## Sources 1.
