[Hiring] Staff Engineer - Virtual Assembly Line @1KOMMA5˚

Role Description

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.

Qualifications

• Extensive hands-on experience in software development with multiple general-purpose programming languages for a minimum of 5 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.

Benefits

• You will enjoy direct contact with core decision-makers.
• You will enjoy the best chances of entering full-time in one of Europe’s most thriving scaleups.

• Benefits and discounts are yours with Futurebens.
• Whether city bike or e-bike - be flexible with our job bike leasing and do something good for the environment at the same time.
