Were 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 cant 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.
