Jobs at Ruby Labs

What Ruby Labs' application asks

Across the 4 application forms Otto has filled at Ruby Labs: 16 distinct questions, 12 of them usually required. A single application works out at about 9 minutes once you have your details to hand. It runs on Ashby.

10 are Ruby Labs’s own, not boxes every form has:

• what experience do you have with ai gateways or model routing solutions (e.g., openrouter or similar)? please…
• please describe your hands-on experience with agentic ai, multi-agent systems, tool-based workflows, or rag…
• are you currently part of any discord, youtube, or telegram communities? if so, please list them below.
• which llm observability tools have you used in production (e.g., langfuse, langsmith, or similar)? please…
• is there anything else you would like to add to support your application?
• what is your availability to start a new role?
• what is your expected monthly gross wage in euros (€) for this position?
• are you located within a ±4 hour range from the central european time (cet) zone?

and 2 more.

Read off the forms themselves, last checked 2026-09-12, because Otto fills them in and has to read them first. Roles differ, so the estimate is per application rather than for the list above: each question counts for its cost times how often this employer actually requires it. A written answer is 2½ minutes, a dropdown 12 seconds, a yes/no 5 seconds, attaching a file 45 seconds. The list leaves out name-and-email boxes and anything Ashby puts on every employer’s form.
