Founding Software Engineer (Path to CTO)

📍 Remote (Europe preferred) | ✈️ Regular travel to South America
🏢 Partner Company – AgTech / IoT Startup (Pre-seed)

🧠 This is not a typical engineering role

We’re not looking for someone who just wants to write code.

We’re looking for a builder — someone excited by ambiguity, ownership, real-world problems, and the opportunity to help build a company from the ground up.

You’ll be the sole engineer, working AI-first, shipping a real hardware + software product, and testing it in cattle fields in South America.

If you’re looking for a polished corporate environment, a large team, or clearly defined processes from day one, this role is not for you — and that’s completely fine.

🏢 About the Partner Company

Our partner is an early-stage AgTech / IoT startup focused on building sustainable, technology-driven solutions with real-world impact.

  • Stage: Pre-seed

  • Focus: Virtual fencing technology for livestock

  • Operations: Europe (founders & HQ) + South America (field operations)

  • Mission: Create sustainable value where progress and responsibility for people and planet go hand in hand

  • Culture: High ownership, AI-first mindset, field-driven problem solving

This is a company where one strong engineer + AI is expected to outperform traditional teams.

💼 The Role

As Founding Software Engineer, you’ll own and ship the entire technical stack and play a central role in shaping the product, the architecture, and the technical direction of the company.

This role offers a clear path to Head of Engineering / CTO, depending on interest and performance.

You’ll work directly with the founders and have full technical ownership from day one.

🛠 What You’ll Be Doing
  • Own the entire technical stack: embedded firmware, cloud backend, and iOS app

  • Take over, iterate, and optimise existing STM32-based firmware

  • Design and build cloud infrastructure from scratch (APIs, data, scalability)

  • Build an iOS app designed for low-literacy, non-technical users (UX, visuals, text-to-speech)

  • Collaborate closely with hardware manufacturing partners

  • Use AI coding tools (Cursor, Claude, GitHub Copilot) as core development partners

  • Travel regularly for hands-on field testing and product launches

  • Ship V1 to market in 2025 and continuously improve reliability and usability

✅ What We’re Looking For (Must-Haves)
  • Strong software engineering fundamentals (language-agnostic)

  • Heavy, demonstrated use of AI coding tools in daily development

  • Experience shipping complete products independently

  • iOS development experience (Swift / SwiftUI)

  • Systems thinking across firmware, backend, and mobile

  • Comfort working autonomously as the sole engineer

  • At least 5+ years of hands-on engineering experience

➕ Nice to Have
  • Embedded / firmware experience (C, STM32)

  • IoT protocols (e.g. LoRaWAN)

  • Cloud backend development (any modern stack)

  • Experience with hardware products

  • Spanish language skills

  • AgTech, robotics, or physical-world product exposure

🚫 This Role Is NOT for You If…
  • You need a large team to be productive

  • You’re skeptical about AI-assisted development

  • You prefer highly structured corporate environments

  • You’re looking for feature-only work without ownership

  • You’re uncomfortable with ambiguity, iteration, and field conditions

🧠 Who Thrives in This Role
  • Autonomous, resourceful builders

  • Low-ego, high-ownership mindset

  • Comfortable with uncertainty and responsibility

  • Strong product sense and user empathy

  • Excited by real-world, physical impact

💶 Compensation & Benefits
  • Base salary: €40,000 – €120,000 (depending on equity track and seniority)

  • Equity: Significant founding-team level equity with vesting over 3 years

  • Contract: Full-time employment

  • Vacation: 28 days per year

  • Working model: Remote-first (Europe preferred) with regular travel

  • Upside: Clear path to Head of Engineering / CTO

🧩 Why Join?
  • Founding-team level ownership

  • Full technical control across hardware & software

  • Real-world impact on sustainable agriculture

  • Opportunity to prove the power of AI-first development

  • Build something tangible, meaningful, and challenging
