Cosuno Ventures GmbH • Berlin, Germany
Role & seniority: AI Automation Engineer (mid-level to senior) focusing on scaling and operating Cosuno’s automation platform.
Stack/tools: Python; n8n; API architecture; RAG; connecting LLMs to proprietary data; vector databases; orchestration and modular automation patterns.
Discovery & Prioritization: partner with Finance, Sales, Ops & Product to identify high-ROI automation opportunities and assess impact vs. effort.
Workflow Engineering: design, prototype, and deploy end-to-end AI workflows; build the orchestration stack and API connections to create a universal memory for Cosuno.
Scaling & Governance: create modular, reusable solutions; establish AI guardrails; enable AI champions across departments; monitor ROI, time saved, and reliability.
Product mindset: treat internal tools as products; focus on business value over “perfect code.”
Technical fluency: proficient in Python, n8n, API design; hands-on with RAG and integrating LLMs with proprietary data.
Applied AI focus and systems thinking: prefer reasoning chains and existing tools over custom model training; view data flows holistically; build scalable, cross-team solutions.
Change agent and pragmatic—able to explain concepts to non-technical stakeholders; ship usable automations quickly.
Your mission As our AI Automation Engineer, you will be the driving force behind scaling efficiency at Cosuno. As the expert for Cosuno’s automation stack, you will partner with teams across the company to identify, design, and implement AI-driven workflows that transform their work. Rather than building or training proprietary models from scratch, you will leverage state-of-the-art existing models and reasoning chains to solve business problems. As part of the product team, you will collaborate closely with the CEO & CTO to ensure all solutions are technically sound and aligned with our core infrastructure. This is an execution-heavy role where success is measured by the speed and reliability of the modular automation platform you build. Key responsibilities
Discovery & Prioritization: Partner with Finance, Sales, Ops & Product to identify high-ROI automation opportunities & evaluate them based on business impact versus technical effort.
Workflow Engineering: Design, prototype, and deploy end-to-end AI workflows by building our orchestration stack (e.g., n8n, Vector Databases) and connecting various endpoints via APIs to build a universal memory for Cosuno.
Scaling & Modularity: Build solutions that are modular and reusable across different departments to avoid "reinventing the wheel" for every new request.
Enablement & Governance: Establish AI guardrails, while enabling AI champions in other departments to work with the automations themselves.
Monitoring & Optimization: Define and track success metrics (ROI, time saved, reliability) to ensure automations deliver continuous value. Your profile
The "Product" Mindset: You treat internal tools like products. You prioritize ruthlessly and focus on business value over "perfect code” or "beautiful UI”.
Technical Fluency: You are proficient in Python, n8n, and API architecture. You have hands-on experience with RAG and connecting LLMs to proprietary data sources.
Applied AI Focus: You prefer building “Reasoning Chains” and integrating existing tools over training custom models.
Systems Thinker: You see the company as a series of interconnected data flows. You naturally see patterns and build modular solutions that scale across teams.
Change Agent: You have experience driving organizational change and can explain complex technical concepts to non-technical stakeholders with ease.
Pragmatic Innovator: You would rather ship a working automation in two weeks than a perfect one in six months, and you have the commercial sense to block non-feasible requests. Why us
Applied AI, Not R&D: You won’t spend months training models that never go live. You’ll leverage the modern stack (LLMs, Vector DBs, n8n) to ship high-impact automations that solve real business problems immediately.
Uncapped Leverage: Construction is one of the last undigitized global industries. We aren't optimizing ad-clicks; we are building the digital nervous system for the physical world. Your efficiency gains here have a massive multiplier effect.
Strategic Ownership: You aren’t hidden in a silo. Collaborating directly with the CEO & CTO, you have the autonomy to identify bottlenecks and build the infrastructure that allows Cosuno to scale. About us Cosuno – Revolutionizing construction through technology. We are Cosuno – a fast-growing tech startup that is making the construction industry more efficient and transparent with our digital platform for tenders and procurement processes. Our goal: to solve the most complex challenges in the industry with innovation and simplicity. Why Cosuno?
Artificial intelligence is the key to our solution: it analyzes millions of price data points and helps construction companies create precise and efficient bids. This not only saves our customers time but also helps them avoid unnecessary costs. But for us, it's not just about technology – it's about the people who drive it. At Cosuno, you will work with creative minds who are reshaping the construction industry. We believe in diversity because we know that the best ideas come from different perspectives. An integrative and inclusive work environment is a matter of course for us. Join us – Build the future of construction.
