Entrepreneur in Residence (Technical)

Lisbon, Portugal (Hybrid) | Full-time | Founder-track | Equity-first

Hi 👋 I’m Gesa, Co-Founder at Phira Ventures.

We’re looking for our next Technical Entrepreneur in Residence: a world-class full-stack builder who wants to go all-in on creating a new company.

The Phira Philosophy: We Bet on Builders

Phira Ventures is a Lisbon and New York–based venture studio. We don’t just write checks; we co-build.

We are a home for ambitious learners. We don't care about your "years of experience" or the logos on your CV. We recently hired someone straight out of high school - because they had already built something extraordinary outside of the classroom. They had the drive to see a gap and fill it.

If you have that same itch to build, we want to give you the resources to do it at scale.

The Opportunity

This is a founder-track path. You aren't just an employee; you are the technical architect of a future venture.

• Solve Real Problems: We build software that delivers tangible value. AI is a core part of our stack because it allows us to build faster and smarter, but we aren't chasing "AI hype." We use it where it improves the product.

• Your Idea or Ours: Bring a concept you’re burning to build, or dive into one of our validated software concepts.

• The Team: You won’t build in a vacuum. We’ll pair you with a co-founder focused on product and GTM, while you own the technical side of the business.

🛠️ What We’re Looking For: Proof of Craft

We have one non-negotiable requirement: You must have a project to show for. It doesn't need to be a commercial success. It could be an app, a complex automation script, an open-source library, or a hardware hack. Show us that you can build yourself, and that you have the drive to do it again.

Apply if you:

• Are an Ambitious Learner: You view a technical hurdle as a reason to stay up until 2 AM mastering a new framework.

• Ship Fast: You’d rather have a working prototype today than a perfect architecture document next month.

• Think Like an Owner: You don’t just follow tickets; you anticipate where the product needs to go and build the architecture to support it.

• Own the Full Stack: You can navigate from the database to the UI without getting lost.

Your Role

1. Validate via Code: Turn a concept into a "v0" product in weeks or even days. Get it into users' hands, listen to the feedback, and iterate.

2. Own the Technical Direction: Choose the right tools for the job. Move fast, but build a foundation that won't paint us into a corner.

3. Scale the Culture: As the venture gains traction, you’ll help hire the engineering team and set the standard for how we build.

The Perks

• Founder Equity: Significant upside in the companies you build.

• The Lisbon Hub: 4 days/week in our hybrid office (including our office dog).

• Growth Support: Access to our international network, co-founder matching, and capital.

• Real Benefits: 24 days vacation, tax support (we pay your accountant), and team events like sunset sailing and Mexican cooking workshops.

• Early-Stage Pay: A salary to cover your living expenses and keep you focused while you build your equity.
