Role Summary

About Kavak

As the first Mexican unicorn, with presence in several countries and an AI-first business model, at Kavak we are redefining the used car market and the experience of millions of users in LatAm. We have been one of the best valued companies in the region and recently closed an investment round of USD $300M led by Andreessen Horowitz, one of the largest investments they have made in Latin America. With this growth, we are excited to add more people to help us build the next chapter of our product, taking our efforts to build with artificial intelligence to the next level.

We are building with AI in our core operation; from conversational commerce, to generative marketing, to systems that extract insights from millions of interactions. We are a team that imagines the impossible, builds it and lives disruption, proactivity and ambition in a context of hypergrowth.

Kavak Values

1. Deliver Impact: You prioritize what generates measurable results and raise the bar using technology and data. You have a consistent track record of delivering relevant and measurable results.
2. Engage Fast: You act on problems and opportunities. You decide on time, advance in short cycles, and adjust when necessary without compromising standards.
3. Engage with Purpose: You act with extreme ownership, taking total responsibility for results that impact your work and aligning decisions with Kavak's vision and purpose.
4. Play to Win Together: You prioritize collective results over individual success.

We are looking for a Semi Senior Engineer to join our Martech Engineering Team and build the foundation of Kavak's marketing platforms.

This is high impact platform engineering work. Your systems will power campaign execution, personalization engines, experimentation frameworks, and data pipelines that influence user journeys at scale. You will work closely with Product Managers, Data Engineers and Marketing stakeholders to convert growth strategies into reliable and scalable software.

You won't be building landing pages: you'll be building the infrastructure that makes marketing at scale possible.

Responsibilities

Systems architecture and design

Data, events and experimentation

• Collaborate with Data Engineering to design event schemas and data flows that drive analytics and attribution.
• Implement message-based architectures through brokers and asynchronous processing.
• Enable experimentation frameworks (A/B tests, feature flags, campaign variants) with high observability and precision.
• Ensure systems can reliably scale during campaign traffic spikes.

Reliability and engineering excellence

• Design fault-tolerant systems, with adequate error handling and controlled degradation.
