Business Systems Engineer (f/m/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 Business Systems Engineer: a business-first problem solver who delivers solutions based in existing products like Salesforce, n8n, make.com, etc. You bridge business needs and technical delivery across customer-facing, stakeholder-facing, and internal contexts, and you build robust, maintainable solutions across our business-systems stack rather than through click-based configuration. You will team up with Software Engineers, Product Managers, Designers, and a CRM Architect across thermondo's business functions.

If you enjoy this

• Bridge business needs and technical delivery — across customer-facing, stakeholder-facing, and internal contexts — and stay accountable for the outcome, not just the ticket.
• Deliver robust, maintainable solutions in code across our stack: Salesforce (Revenue Cloud, Field Service), JustOn, Payhawk, n8n, Make, etc — favouring code, version control, and tested change over point-and-click configuration.
• Guide the platform's design: give best-practice guidance to the software engineers who own Salesforce data objects and key flows, and be the deep product knowledge they rely on.
• Enable others — raise the capability of software engineers, product managers, and designers through pairing, review, documentation, and teaching.
• Improve the business systems and the processes they support, leaving them measurably better than you found them.

And recognise yourself here

• A business-first problem solver who leads with the problem and the outcome, comfortable in customer-facing, stakeholder-facing, and internal settings.
• Deep, hands-on knowledge of the platforms in our stack: Salesforce (Revenue Cloud, Field Service), JustOn, Payhawk, n8n, Make, and Claude.
• Technically minded — with the help of AI, you deliver robust, maintainable solutions in code, not click-based configuration, with the version control, testing, and review habits that implies.
• An enabler of others, with a track record of levelling up the people around you.
• Proven at improving business systems and the processes they support.
• AI-first — you use AI tooling fluently as a default way of working.

Bonus points

• Real depth in Salesforce Revenue Cloud or Field Service.
• Field-service, billing and finance systems, or subsidy-heavy B2C domains.
• Comfort building automations and lightweight services outside the CRM (n8n, Make, or custom code).

What we have to offer

• 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
• Boost your skills with a dedicated annual learning budget to spend on conferences, courses or books
• Choose your own AI coding companion – we provide you with the license for the AI model or assistant of your choice
• 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
  • Work from home - up to 3 days a week
  • You receive an Urban Sports Club membership & nilo.health membership
  • You can lease a job bike or bring your dog one day/week
  • Corporate Benefits at more than 100 partners
  • 20% employer contribution to your pension and disability insurance
