About the role:
We are looking for a Technical Support Engineer to support Kiefer Tech’s B2B AI/robotics products.
This is not a basic customer support role. You will investigate technical customer issues related to robot software, product workflows, APIs, integrations, logs, configuration, and customer environments.
In this role, you will collect technical context, communicate with customers, investigate issues, and work with Engineering and Product to resolve problems or escalate them with clear, useful information. The role also includes improving troubleshooting guides, escalation flows, internal runbooks, and customer feedback processes.
Kiefer Tech is still building its support structure as the company scales. Processes are evolving, so this role requires someone comfortable with ambiguity, ownership, structured troubleshooting, and building practical support flows from scratch.
Important: this is an office-based role. We are currently considering candidates who are already based in Athens and able to work from our office.
What you will do:
Handle technical support requests from B2B customers and own them through resolution or clear escalation
Investigate issues related to product behavior, robot software, APIs, integrations, logs, configuration, and workflows
Ask the right questions, collect technical context, read logs, and identify possible causes
Document issues clearly for Engineering/Product, including impact, evidence, steps to reproduce, and expected vs. actual behavior
Communicate clear and calm updates to customers during technical investigations
Create FAQs, troubleshooting guides, runbooks, and internal support notes for repeated issues
Identify recurring customer problems and share useful feedback with Product and Engineering
Help make the support process more structured, scalable, and less dependent on ad hoc communication
What you will need:
3-5+ years of experience in technical support, application support, product support, L2/L3 support, or a similar role
Experience supporting B2B technical products
Strong troubleshooting and problem-solving skills
Ability to read logs, understand error messages, and collect useful diagnostic information
Understanding of APIs, integrations, authentication issues, and basic debugging flows
Experience working with Engineering/Product on technical customer issues
Clear, calm, and empathetic customer communication skills
Fluent Greek and English
Based in Athens and ready to work from the office
Comfortable with early-stage processes, ambiguity, and high ownership
Nice to have:
Experience supporting complex B2B technical products, such as AI, automation, robotics, IoT, edge devices, cloud, infrastructure, or hardware-software products
Linux basics, networking basics, monitoring tools, or observability tools
Basic scripting, SQL, or log/data analysis
Experience with enterprise customers and support documentation/runbooks
What is there for you:
Office-based role in Athens
B2B AI and robotics products at Kiefer Tech
Opportunity to help build and structure the technical support function
Direct impact on how customer feedback influences Product and Engineering
Small team, high autonomy, low bureaucracy, and room to build practical processes from scratch
