CTO & Co-founder Recruiting Tech (Remote - Lisbon)

A-ha! Ready to disrupt recruitment?

We're ambi.careers – not your average recruitment agency. We're building a talent marketplace and other AI powered recruitment tools, to connect brilliant professionals with startups and scaleups that are changing the game.

No BS here. After years in executive recruitment and building startups from scratch, we're sick of the empty promises, cookie-cutter approaches, and soul-crushing corporate speak that plagues this industry.

We're combining cutting-edge tech with real human insight to create something that actually works for our clients.

The opportunity: Simple – we want to really step up our tech products and need a Co-founder/CTO to help us define the vision and scale. Our vision is massive, and we need tech firepower to match. We also believe we could bootstrap together til very far, so we probably don't wanna go through the classic startup funding path, but generate real income asap.

What we’ve built so far

A working AI-powered sourcing tool

Real jobs, candidates, and data flowing through the system

Early version of our market insights module

A talent marketplace and job board creator we already run for VC funds

A lean and validated roadmap for real client impact

Real users using this every week

What we’re looking for

We’re seeking a CTO Co-Founder who wants to build real product, not just ideas. You’ll lead technical development and help shape the product — while keeping things simple, lean, and focused on real value.

You can freelance elsewhere in the beginning. There’s no salary at this stage — but there’s equity, ownership, and freedom.

You’re probably a fit if you:

Are hands-on with code (especially Python, APIs, AI integrations)

Have practical experience using AI (e.g. LLMs, Gemini, scraping, automations)

Know how to build lean backend-first MVPs (FastAPI, Streamlit, etc.)

Enjoy building things people use — fast, smart, and without BS

Want equity and money from a real, potential bootstrapped product

See yourself scaling this with us (even slowly at first)

Tech stack (current & expected)

Python (FastAPI or Flask)

Streamlit for UI

Google Gemini API (we’re open to changing LLM providers)

PostgreSQL or SQLite

Bubble would be nice

API's in general

Web Crawlers

Advanced scraping (LinkedIn public pages, job boards)

Render, Railway, etc.

What we offer

Equity in the product — clean cap table, fairness and transparency

Clients and data from day one

Real-world use case + revenue already happening

Autonomy and room to shape product + tech

Option to start part-time, then go deeper

A lean roadmap and no time wasted on fake traction

Next steps

We’re open to builders who want to start part-time, and grow into a founding role. If you want to work on something real, smart, and ready to scale — let’s talk.

This is for you if:

• You've built software for HR-tech, marketplaces, or similar platforms
• You're wasted as just an employee – you want to build something that matters
• You've got hands-on AI experience and can see its potential in recruitment
• Your English is good (our clients and candidates are primarily native speakers)
• You have a genuine growth mindset and want to build something from the ground up
• You can commit real time to this – not just scraps after your day job
  
  
  

Not for you if:

• You expect a fat co-founder salary from day one
• You're an ego-driven tech bro with zero empathy
• You crumble when things get tough (and they will)
  
  
  

Ready to revolutionize how talent finds their place in the tech world? We're going to be the #1 destination for startups and scaleups looking to hire exceptional talent, and you could be the technical brain behind it.
