If you're passionate about building lovable products, we want you to join us!

Know the Web Developers Team

We level our activities here with a clear measurement scale: excellence. Our team builds the most lovable products around. With fellowship, ownership, and passion we build and ship web-related products, tailored for the most distinct scenarios and necessities. We are eager for innovation. That's why we have study groups, meetups, and web talks that help us stay up to date on the latest technologies, and the most awesome part is that we grow together that way. With all that, we aim to improve on every project and delivery, always aligned with our purpose: to help our clients become superheroes.

Role expectations:

Front-end:

- Design, customize, and optimize Shopify themes from scratch or existing templates, writing clean and modular Liquid code, HTML, CSS, and modern JavaScript;
- Design and create data fetching and state management systems on the front-end using Flux, Redux, or Mobx (but if you are familiar with another tool that may do a great job with that, bring it on);
- Partner up with our Product Designers to iterate, validate and improve the design of our product;
- Write unit tests to detect and prevent any changes that may break the design contract;
- Focus on cross-browser development, deploying the same user experience for a wide range of browsers, even those not chromium-based.

Back-end:

- Develop and maintain well-designed back-end services, easy to scale and maintain, secure and robust, using NodeJS, Go (Golang), or Python;
- Build custom Shopify Apps (public or private) and integrate Shopify with external third-party systems (ERPs, CRMs, fulfillment, and payment gateways) using Shopify Admin APIs (REST and GraphQL);
- Design, implement and maintain scalable REST APIs, secure and reliable that can be consumed by either mobile and web applications;
- Deploy, monitor, and maintain back-end applications, aim for top performance, security, and scalable infrastructure, using AWS, Azure, or Google Cloud .

General

- Experience with modern Shopify development workflows, including Shopify CLI, Theme Kit, GitHub integration, and ideally Headless Commerce architectures (Hydrogen/Remix or custom storefronts);Define and implement a fit usage of GitFlow, using either GitHub, GitLab, or any other git repository;
- Design and build readable code, well-defined architecture, following the OOP pillars: Encapsulation, Data Abstraction, Polymorphism, and Inheritance (hey, Functional Programmers, feel free to join as well. We’d love to level our products with some FP);
- Architect, design, and implement databases, either relational and non-relational, using Microsoft SQL SERVER, MySql, MariaDB, MongoDB, Cassandra or any other available database;
- Participate in the hiring process for your chapter by doing tech interviews, helping the company to hire more talented people like you;
- Engage in English meetings with our clients, helping them identify better approaches and solutions, sustain opinions on complex conversations to negotiate and estimate deadlines.

On a typical day with us, you will:

- Work seamlessly with both frontend and backend technologies, including Shopify store customization, app development, and e-commerce integrations;
- Keep yourself up to date on the latest market technologies, and Shopify ecosystem updates (new API versions, Online Store 2.0 features, etc.);
- Analyze different contexts always looking to improve the experience of our projects in both coding and execution;
- Join tech discussions about the project, tech challenges and how to improve our solutions;
- Have a clear communication with our clients, leveling expectations and project definitions;
- Support your teammates and help them to keep learning and developing their skills;
