Senior Software Engineer (80-100%)

Enerlytica provides data-driven products for the energy market based on its proprietary Energy Analytics Platform. We’re looking for an experienced software engineer who enjoys turning ideas and PoC code into reliable, maintainable, and observable production systems at the intersection of backend engineering and data-driven product development. The role is ideal if you like owning the lifecycle from prototype to production and thrive in a pragmatic, product-focused environment.

What you’ll do

• Improve a legacy PHP system by extracting business logic into modern Python services
• Refactor data science notebooks/scripts into clean, modular Python code and services
• Build and maintain data-driven backend services, APIs, pipelines, and scheduled jobs
• Design and operate small to mid-size production systems with clear interfaces and monitoring
• Improve reliability through code reviews, testing, observability, and incremental refactoring
• Collaborate closely with our CTO, data scientist, cloud infrastructure specialist, and project manager; coordinate with part-time engineers as needed

What you bring

• Strong Python engineering skills (architecture, modular code, tests)
• Experience writing production-ready software
• Experience with backend services and APIs
• Experience with Git in a professional team setting
• Solid understanding of deployment, monitoring, and reliability
• Ability to work independently in a remote setting
• You are based in or close to Germany, Austria or Switzerland

Nice to have (not required)

• PHP development and refactoring skills
• JavaScript and some frontend experience
• Experience with ClickHouse or other analytical databases
• Familiarity with orchestrators like Prefect, Airflow, Dagster
• Experience in energy, IoT, or data-intensive products
• German speaking

How we work

• We are a small but very well-trained and therefore powerful team of experts
• We are located in Switzerland, Germany and Austria – but we work almost exclusively from home
• No one is a lone wolf with us – despite the physical separation, we work very closely together
• You will take on responsibility right from the start, but you will never be left alone
• You will be given a lot of flexibility in structuring your work, your working hours and your place of work
• Together we support the energy transition to make the world more sustainable for new generations
