Join the engine room of the energy transition!

The Branch Success Team is the critical link between 1KOMMA5°'s groundbreaking technology and our regional teams. We're looking for a Technical Support Specialist to join our mission in Berlin, Munich, or Hamburg (or remote within Germany).

You won't just be answering questions; you'll be the first responder and problem-solver for the Virtual Assembly Line—our proprietary suite of tools that powers everything from sales to installation. This is a hands-on role where you will directly impact the daily efficiency of our locations and help us scale the future of clean energy.

Become a part of our mission and learn more about our Product & Tech team!
Your mission
As a Technical Application Support Specialist, you will be a trusted partner to our internal users, ensuring they can leverage our complex systems with confidence.
  • Technical Troubleshooting & Root Cause Analysis: Provide expert 1st and 2nd level support for our core sales and operations tech stack (including proprietary and third-party software). You will be expected to go beyond surface-level issues, using tools like Datadog to investigate logs, reproduce errors, and identify the root cause.
  • End-to-End Issue Ownership: Be the champion for our users. You will own support tickets from the initial report to the final resolution, taking full responsibility and collaborating closely with your team and other departments to find the best possible solution.
  • Collaborate with Product & Engineering: Act as the "eyes and ears" of our product teams. You will identify and document recurring issues, user pain points, and bugs, providing clear, data-backed feedback that directly contributes to improving product quality and the overall user experience.
  • User Enablement & Knowledge Creation: Go beyond reactive support. You will play a key role in empowering our users by creating clear documentation, building out our knowledge base, and helping to educate regional teams & employees, turning problems into learning opportunities.
Your profile
  • You are a proactive, empathetic problem-solver with a knack for making complex systems feel simple

  • Experience: A minimum of 2 years in a Technical Support, Application Support, or a similarly technical customer-facing role, ideally within a fast-paced tech environment

  • Technical Aptitude: You have a strong ability to troubleshoot complex software issues. You are comfortable reading logs, identifying patterns, and have experience working directly with developers to resolve bugs. Hands-on experience with monitoring tools (like Datadog) is a major plus

  • Systems Knowledge: Hands-on experience supporting CRM systems (Zoho is a huge plus!), VoIP tools (Aircall), and other integrated SaaS applications

  • Communication Skills: Excellent communication skills in both German and English (written and verbal, C1/C2). You can explain technical concepts clearly to a non-technical audience.

  • Mindset: A strong sense of ownership and a collaborative spirit. You are a curious and relentless problem-solver who is driven to find not just a workaround, but the real solution.

Benefits
  • You are part of an international, dynamic, and highly motivated team of people who have proven to make things happen
  • With your work, you accelerate the "energy transition" and hence have a direct impact on our climate
  • Work with and learn from other super-smart colleagues
  • 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 Scale-ups
  • You work remotely (Germany-wide), with offices in Hamburg, Berlin or Munich
  • Create a healthy balance alongside your work and enjoy all the benefits of the EGYM Wellpass
  • 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
