Staff Engineer - (m/w/d)
We're looking for
At thermondo, our mission is to decarbonize every home, and technology is our primary lever for change.
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 (m/w/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.
- 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.
- Experienced: You have significant experience (10+ years) in software engineering, including operating at a Lead or Staff level in a modern product company.
- Full Stack: You have deep, T-shaped expertise. 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.
- 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.
- 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
- 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
- You can bring your dog one day/week

Every application is welcome here - regardless of gender, nationality, ethnic and social background, religion, ideology, disability, age, sexual orientation or identity. We are convinced that everyone is valuable and deserves a fair chance.
