Summary

As a Senior Software Engineer at Platzi you build and own the systems that companies use to train their teams with us: the data model, the services, the integrations, how they behave under load, and how they recover when they break. You join a team focused on our B2B business, building AI-powered products for companies, and you report to the Engineering Manager. 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. You care about the business problem behind every feature and about what your code costs to run and to maintain a year from now, not only about getting it merged.

Requirements

Responsibilities

• Design and build services, data models and interfaces that hold up as the product and the traffic grow.
• Own what you build in production: performance, reliability, cost, and how it recovers when it breaks.
• Start from the business problem: understand what customers and internal teams need, translate it into a feature, and measure what it delivered.
• Make architecture decisions you can defend, and say no to complexity that doesn't pay for itself.
• Use AI and LLMs to go faster on design, implementation and review, and review what they produce as strictly as your own code.
• Raise the bar around you through code review, standards, and the calls that stop bad decisions early.

Requirements

• At least 5 years shipping and operating software in production, with real depth in system design.
• Strong fundamentals: data modeling, APIs, performance, concurrency and failure modes.
• Experience building B2B / SaaS products.
• You've owned a system through real scale or a migration, and can explain what you'd do differently now.
• You can weigh a technical decision against what the business needs, and explain the tradeoff to people who don't code.
• Fluent English and Spanish.
• Nice to haveExperience working directly with customers or close to commercial, customer success or support teams.
• Experience building products on top of LLMs.
