• LLM pipelines for writing and maintaining code
• We use AI-first approach in engineering

💥 What You’ll Actually Do

• Build product from scratch and own large chunks of it

• Help define our architecture, engineering culture, and hiring bar
• Wear a few hats. Break a few things. Fix them fast.

⚡ You Might Be a Fit If:

• You’re excited by the mission: digitally connecting the world’s logistics through great tech
• You want to work with founders, not layers — and you want your work to matter now

🚫 Reasons You Shouldn’t Apply

• You want clearly defined roles, long-term roadmaps, and tight specs before starting work
• You prefer long discussions and consensus-building over fast decisions and iteration
• You’re not comfortable with messy problems, changing priorities, or unclear ownership

• You don’t want to touch things outside your lane — infra, product, clients, whatever

🧠 Bonus Points For:

• DevOps skills (we’re on Azure)
• Experience working with logistics APIs (e.g., carriers, 3PLs)
• LLM / AI agent workflow experience
• Startup / scaleup experience

🛠️ The Process

We like to move fast, stay human, and keep things high signal.

1. Intro Call — A quick, informal chat to get to know each other
