Staff Engineer - Virtual Assembly Line (m/f/d)

## 1KOMMA5°

At **1KOMMA5°**, we pursue a clear vision: **Living on wind and sunlight forever for free**. To make this a reality, we are building the energy system of the future with Heartbeat AI. Want to be part of it?

We bring together regional craftsmanship and scalable software: We don't think of solar, batteries, heat pumps, and e-mobility as isolated components, but control them as an intelligent, integrated overall system in our virtual power plant. Directly connected to the electricity market – in real time, fully automated. This way, energy is used when it is available from renewables and particularly cost-effective. By 2030, our goal is to transition 1.5 million households to renewable energies. Over 3,000 people are working towards this every day, at more than 80 locations worldwide, from Finland to Australia.

**Want to take responsibility and build solutions that truly matter? Apply now and help us shape the energy world of tomorrow.**

## Deine Position

You'll help shape the Virtual Assembly Line (VAL) team, which builds and scales our growth and operations systems: MarTech, CRM, Payment, Fulfillment and Installation, so we can scale globally with maximum efficiency and quality.

• Own technical direction across VAL's growth and operations engineering domain, keeping architecture aligned with product direction, and hold the team accountable for consistent execution of those decisions
• Set the technical bar for the teams, stepping into the hardest problems yourself rather than just directing others
• Translate business and product requirements into technical solutions that scale as we digitize the installation branches further
• Architect our systems and APIs so AI agents operate as first-class users with machine-readable contracts
• Drive VAL's shift to agentic engineering, reshaping how the team works so agents execute safely while humans stay accountable
• Mentor and challenge engineers within VAL to accelerate their growth
• Build a high-performing engineering culture within the VAL team
• Embed security and reliability as direct customer value

## Technologies you will work with include:

• AI-assisted development with Cursor / Claude and agentic coding workflows
• Languages: TypeScript (React, Nest.js, Next.js, VueJS), Ruby on Rails, Flutter
• Cloud & Infra: Google Cloud Platform, GKE (Kubernetes), Cloud Run, Terraform/IaC, Vercel, Datadog
• Data & BI: PostgreSQL, BigQuery, SQLMesh, Looker
• Linear, Notion, Figma, Miro

## Dein Profil

• Extensive hands-on experience in software development with multiple general-purpose programming languages for a minimum of 10 years
• A proven track record of architecting scalable and secure systems, demonstrating a strong commitment to quality
• Extensive experience designing and implementing APIs that enable seamless integration between systems, as well as for non-human/automated consumers like AI agents
• An agile and result-oriented mindset, with a strong emphasis on collaboration and teamwork
• Experience communicating with stakeholders in business terms and understanding the technical implications of their requirements
• Experience driving technical alignment within a team in fast-paced environments, including making and following through on critical technical decisions
• Track record of leading a team through a major workflow or tooling shift, with the judgment to know where automation (including AI agents) can run safely and where human sign-off stays mandatory
• Proven ability to own features end-to-end, from rough problem statement to shipped, maintained product, working closely with product managers and business stakeholders across the company
• Strong verbal and written communication skills in English, with proficiency in German considered a plus
