Senior Full Stack & Data Engineer - Python | Snowflake | TypeScript | React | Next.js | Azure — Latin America

We are wJFt, a company driven by our constant pursuit of knowledge, learning, and doing what we are passionate about. We are a multidisciplinary team focused on designing and developing user-centered digital experiences that create real value and have a positive impact on organizations.

About the Role

We are looking for a Senior Full Stack & Data Engineer to take ownership of the architecture, development, and evolution of a software platform built for a professional sports organization.

This is a hands-on, high-impact engineering role for someone who enjoys solving complex business problems through technology, building scalable systems, and working closely with both technical and non-technical stakeholders.

You’ll work across the entire technology stack, combining data engineering, backend development, frontend applications, cloud infrastructure, and enterprise integrations. You’ll help transform an existing set of working solutions into a cohesive, reliable, and scalable platform.

You won’t just be implementing requirements. You’ll have a voice in shaping the product, influencing technical decisions, and determining how the platform evolves.

What You’ll Do

Data Engineering & Architecture

• Design, build, and maintain production-grade data pipelines using Python and SQL.

• Work with Snowflake, including data modeling, transformations, orchestration, and migration initiatives.

• Ensure data quality, reliability, scalability, and recoverability across data workflows.

• Design robust processes for incremental loads, backfills, reconciliation, and error handling.

Full Stack Development

• Build and maintain modern web applications using React, Next.js (App Router), and TypeScript.

• Develop backend services, APIs, and reusable application capabilities.

• Create fast, reliable, and user-friendly interfaces that support day-to-day business operations.

• Implement automated testing, observability, and maintainable application architecture.

Cloud Infrastructure & Integrations

• Build and operate solutions within Azure cloud environments, primarily using Azure Container Apps.

• Develop integrations with enterprise platforms such as Salesforce, Salesforce Marketing Cloud, Meta, Attentive, and Asana.

• Design secure APIs, webhooks, authentication, authorization, and asynchronous processes.

• Apply cloud security best practices, including managed identities, secrets management, encryption, and infrastructure as code.

Technical Leadership & Product Collaboration

• Take ownership of architecture and engineering decisions across data, backend, and frontend systems.

• Turn early-stage prototypes into robust, production-ready solutions.

• Participate in client meetings and collaborate directly with business stakeholders.

• Translate business challenges into technical solutions and help shape product priorities.

• Establish engineering standards, code review practices, CI/CD processes, documentation, and deployment discipline.

What We’re Looking For

• 6+ years of experience building and maintaining production software systems.

• Strong hands-on experience across both data engineering and user-facing application development.

• Advanced Python and SQL skills.

• Production experience with Snowflake or comparable data platforms.

• Strong experience with TypeScript, React, and Next.js.

• Experience designing and developing backend APIs, integrations, and asynchronous processes.

• Cloud infrastructure experience, preferably with Microsoft Azure. AWS or GCP experience is also valuable.

• Strong understanding of software architecture, system design, data modeling, and engineering best practices.

• Experience working with automated testing, CI/CD, observability, and infrastructure as code.

• A product-oriented mindset and the ability to translate business needs into technical solutions.

• Excellent written and spoken English, with the ability to communicate effectively with clients and stakeholders.

• Strong ownership mentality, problem-solving skills, and attention to detail.

Nice to Have

• Experience with Salesforce, Salesforce Marketing Cloud, Meta Ads, or other marketing technology platforms.

• Background in sports technology, ticketing, live events, retail, or customer engagement.

• Previous experience in consulting, agencies, or client-facing engineering roles.

• Deeper experience with Azure services such as Azure Functions and Azure Data Factory.

• Experience with event-driven or streaming data architectures.

• Experience using AI coding assistants and development agents as part of your engineering workflow.

How We Work

• High ownership: You’ll work closely with the founder and have significant influence over technical and product decisions.

• End-to-end responsibility: You’ll own implementation and architecture across data, backend, frontend, and cloud infrastructure.

• AI-native engineering: We embrace AI-assisted development while maintaining high standards for code quality, testing, security, and documentation.

• Direct client collaboration: You’ll work closely with business stakeholders and understand the problems you’re solving firsthand.

• Quality first: We value clean architecture, reliable systems, maintainable code, and solutions built to last.

What Success Looks Like

In your first months, you’ll gain ownership of the existing platform, strengthen its architecture, improve data reliability, and help evolve the current solutions into a cohesive production-ready system.

Ultimately, you’ll help build a well-documented, secure, and scalable platform that the client’s internal teams can confidently operate and maintain.

If you’re a hands-on engineer who combines strong technical depth with architectural thinking and product sense, we’d love to hear from you.
