About X-Via

In the digital era, the transformation of the public sector is essential to improve citizens' lives and make government more efficient.

Founded in 2017, X-Via was born from its partners' perception of the need for technologies that facilitate the public sector's journey towards digital government.

Job Description

Will work on a Digital Government project remotely, integrating a platform with open-source solutions and proprietary technology. The environment is based on TypeScript and uses modern frameworks such as NestJS, NextJS, Express, React and React Native/Expo. The architecture involves SSR/CSR applications, microservices, REST APIs, SSO (Single Sign-on), messaging queues and observability that make up a distributed ecosystem.

Responsibilities

• Develop and maintain full-stack features.
• Integrate services and APIs.
• Build robust APIs and scalable microservices.
• Contribute to the design and architecture of applications, always focusing on user experience and system efficiency.
• Be responsible for monitoring and observability of applications.
• Ensure code quality (code reviews, unit/integration test coverage, CI/CD pipelines) and optimize the development lifecycle according to best practices.
• Take ownership of tasks: identify problems, propose solutions and carry them forward without relying on micromanagement.
• Participate in planning and design meetings, communicating effectively with cross-functional teams to align technical and product objectives.
• Work in an agile environment, participating in refinements, plannings, dailies and retrospectives.
• Work collaboratively in a team.

Requirements and Qualifications

• Proven experience with Databases and SQL (MySQL, Postgres, etc).
• Experience with test development.
• Experience in integrations with SSO (Single Sign On).
• Mastery in containerization (Docker).
• Knowledge of architecture patterns (microservices, REST/GraphQL).
• Use of Analytics tools (GA, Matomo, PostHog, etc).

Nice to Have

• Experience with React Native/Expo.
• SSO Authentication (OAuth2/OpenID).
• Familiarity with application observability.
• Knowledge of CI/CD and cloud infrastructure.

Personal Profile

We are looking for someone proactive and committed, who takes responsibility for deliveries and does not "push" problems forward. Must have a strong collaborative spirit and good communication, contributing to the team's evolution. We value analytical thinking as the professional will participate in every stage of the product, ensuring the best user experience and technical quality. Attention to quality is essential – those who take the initiative to write automated tests and review deliveries contribute to product excellence.

What We Offer?

• Indefinite-term contract (Contractor/PJ).
• Collaborative environment, with autonomy and real challenges.
• Paid leave of up to 30 days per year to be arranged with the manager.
