- Obsessed with continuous improvement: you seek feedback, give constructive feedback, and raise the bar for yourself and others
- You thrive in collaborative environments, value feedback, and help others raise the bar
- You’re passionate about your craft, the product, and the impact we create for our customers
- Fluent in English and Spanish
- We require eligibility to work in Spain and are also open to collaboration agreements

- Safeguard delivery pace: reduce blockers, manage technical debt, and keep flow sustainable
- You bring a product engineering mindset: your focus is always on building quality features that create real value
- You think beyond code: always asking “Is this important? Does it improve the customer’s life? Does it reduce costs or unlock new opportunities?”
- Stay close to the user: deeply understand who they are, their problems, frustrations, and behaviors. Great engineers don’t just write code — they connect technology to real people, ensuring our work creates meaningful impact in the market and in users’ lives
- You balance speed and quality: knowing that quality isn’t the opposite of agility but its foundation
- You lead through ownership and autonomy, ready to make an impact both in the product and in the team
- You foster collaboration, feedback, and learning, because great teams outperform brilliant individuals

Our take
Chatbots have been around for quite some time and have seen a few iterations over the decades. But chatbots can require heavy coding which is costly, time consuming and can only be executed by professionals. There was also a huge gap between user expectations and reality.
Landbot had the idea to create a drag-and-drop style bot-builder that doesn’t require coding to support custom conversation flows. This quickly proved to be popular with customers, and the company have grown exponentially, being trusted by thousands of leading businesses including Coca-Cola, Nestle and Prudential.
Back in 2021, Landbot acquired Morph.AI, a chat-based marketing automation tool based in India. This supported its expansion into the Asian market, as the company aims to secure a position for itself against competition from other players like ManyChat.
