The position

Job description

At Hexa, we launch startups from 0 to 1—again and again. But ideas and capital aren’t enough. We need people who build fast and make it resonate!

That is why we’re looking for a Tech Builder with storytelling instincts—someone who creates bold, testable products and naturally showcases their work. You’re not behind the scenes: you shape both the product and the narrative.

This is a hybrid role: 80% building, 20% evangelizing.

1️⃣ Build — Prototype at speed (80%)

🎯 Bring ideas to life

Work with our Partners and PMs to challenge, shape, and test early-stage projects.

You won’t build everything yourself—but you’ll set the standard, coach teams, and de-risk technical decisions.

  • Empowering CTOs, embrace the 0-1 speed, share latest AI best practice

  • Prototype bold ideas with the latest tools (AI, no-code, fast frameworks).

  • Structure early MVPs and architectural foundations.

  • De-risk product bets and generate conviction for Founders.

Your impact: you accelerate learning, reduce waste, and turn ideas into leverage.

2️⃣ Evangelize — Become Hexa’s tech voice (20%)

🎯 Make our tech visible

Turn what we build into stories worth sharing—show how we think, build, and iterate.

  • Create weekly content: demos, posts, talks, events.

  • Share our vision across GitHub, LinkedIn, Discord, and more.

🎯 Connect the community

Energize our Tech Founders by connecting them with the best experts when they need help.

  • Engage with top builders and open-source contributors.

  • Foster relationships between current and alumni CTOs.


Preferred experience

  • You’re a hands-on builder: you’ve shipped real things, fast, solo or in small teams.

  • You’ve seen scale-ups—but your sweet spot is 0 to 1. You love the chaos, speed, and creativity of building from scratch!

  • You’re fluent in code and storytelling

  • You thrive in the unknown — No brief? No team? No problem!

Perks & Benefits

  • Equity in every startup created

  • Competitive package (Salary + profit-sharing)

  • Swile (green transportation and meal vouchers), SideCare (health insurance)
