If you do NOT want to disappear inside a large company doing small, invisible tasks for months – surrounded by people who don’t care, buried in bureaucracy, time tracking, and performance reviews that lead nowhere – this role may be for you.
 

If you DO want to work somewhere your contribution counts, where you can grow fast and work on real problems that actually matter – keep reading.
 

What the work actually looks like

• Design, deploy, and manage AI agents that automate real workflows
• Ship internal tools, external tools, and small applications end-to-end
• Solve practical engineering problems fast — integrations, scripts, automations, backend logic

We care more about how you think than what you’ve already shipped.

You’ll likely fit this role if:

• You use AI tools naturally as part of how you work
• You scope problems before writing code — and know what to skip
• You notice details others miss
• You’re honest about what you don’t know, and quick to figure it out
• You’ve built something recently, even if it was small

What we don’t care about

• Your years of experience
• Whether you’ve worked at a well-known company
• A perfect CV

Stack

We use what fits the problem. You should be comfortable with JavaScript, basic deployment, and working directly with APIs and LLM-based tools.

Our hiring process

• Short assessment (~45 min)
• Interview with the founder
• If it clicks, we move fast

Short assessment

We use a testgorilla for our short assessment. No trick questions. No algorithm puzzles. Just practical scenarios that reflect what the job actually looks like.
