Job description

About Us

Platzi is the largest technology school in the Hispanic world with over 7 million students and 4,000 companies trusting us to deliver effective online education. Our mission is to make Latin America a technology superpower. We do it by training companies and individuals in areas such as AI, Cybersecurity, English, Programming and Leadership.

As an industry leader, our presence is highlighted by our massive and fanatic community, extensive press coverage and a daily stream of success stories from students. We operate mostly remote, with key offices in Bogotá, Medellín and Mexico City.

Summary

As a Senior Software Engineer (Learn) at Platzi you're an engineer first: you build and own systems that hold up in production, and the material you build them with is AI. Orchestration, evals, and the models behind each decision, all serving how millions of students in Latin America learn in the product. You report to the AI Lead. Seniority here means judgment, not distance from the code. You take an ambiguous problem and come back with a decision you can defend, including the decision not to build, and you care about what your code costs to run and to maintain a year from now, not only about getting it merged.

Requirements

Responsibilities

• Build AI features that ship to students, and own them in production: performance, reliability, cost, and how they recover when they break.
• Design the orchestration behind them: agents, tools and the flow between them, built to be debugged and not just demoed.
• Make evals part of how you work, so you know what improved, what regressed, and what you're trading off.
• Choose the right approach for each problem, whether that's an LLM, a classic model, or plain deterministic code.
• Make architecture decisions you can defend, and say no to complexity that doesn't pay for itself.
• Raise the bar around you through code review, standards, and the calls that stop bad decisions early.

Requirements

• At least 5 years building software in production, including owning a system through real scale or a migration.
• Strong fundamentals: data modeling, APIs, performance, concurrency and failure modes.
• You've taken LLM-powered systems to production, not prototypes, and you know where they broke.
• You move comfortably across frameworks like Pydantic, Agents SDK and A2A, and can explain why you chose each one.
• Experience with classic machine learning, and the judgment to know when a model beats a prompt.
• A product you built that we can see and use.
• Fluent English and Spanish.

Benefits

Hardware

With Platzi's help, you will have 100% of the necessary work tools such as a laptop, smartphone, desk, ergonomic chair, monitor, and other accessories.

Books

We provide you with all the books you need to grow professionally on Kindle, and we give you the Kindle too.

Maternity/Paternity Leave

At Platzi, we believe in gender equity and the importance of parents in the upbringing and care of their children. We make this a reality for new mothers and fathers through extended maternity and paternity leave.

Option Pool

All members of the Platzi Team have the opportunity to own a part of Platzi and have company shares.

Vacation

You have 15 days of vacation per year regardless of the country you are in, starting from the moment you join the team.

Online Therapy

We care about your emotional health by covering the first four online therapy sessions with specialized companies.

Team Syncs

Although we are in different parts of the world, Platzi teams meet in person during the year to exchange ideas, build, and strengthen bonds.

Villa Platzi

Every year, the entire team gathers somewhere in the world for a week to meet face-to-face, get to know each other, have interesting discussions, and plan ambitious projects.
