We're looking for

At thermondo, our mission is todecarbonize 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 - 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.

And recognise yourself here

**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.

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.
