As a Full Stack Software Engineer, you will develop applications and platforms that enable users to explore, visualize, and interact with data in meaningful ways.

We will count on you to:

• Contribute to the design and development of full-stack applications using MEAN/MERN technologies and Python FastAPI.
• Develop and maintain applications that enable data exploration, visualization, and reporting.
• Design and develop microservices and APIs using an API-first approach, including integrations and JSON data handling.
• Develop and deploy scalable applications using container technologies such as Docker, Kubernetes, or similar, with an understanding of Git and CI/CD practices.
• Optimize application and front-end performance for speed, scalability, and a strong user experience.

What you need to have:

• Bachelor’s degree in Computer Science, Software Engineering, or a related field, or equivalent practical experience demonstrated through relevant projects.
• At least 3 years of professional software engineering experience, including experience with Python/FastAPI and a MEAN or MERN stack such as Node.js, Express.js, Angular or React, and MongoDB.
• Experience working with SQL and NoSQL databases, API integrations, JSON data, and responsive, scalable application development.
• Strong problem-solving and communication skills, with the ability to work independently and collaboratively in a fast-paced, deadline-driven environment.

What makes you stand out?

• Experience with front-end styling frameworks and tools such as Tailwind, Bootstrap, or Sass, and UI component libraries such as Material UI or Hero UI.
• A strong spirit of innovation, curiosity, and continuous learning, combined with the ability to build relationships, align stakeholders, and take a user-centric approach to solving business problems

Why join our team:

• We help you be your best through professional development opportunities, interesting work and supportive leaders.
• We foster a vibrant and inclusive culture where you can work with talented colleagues to create new solutions and have impact for colleagues, clients and communities.
• Our scale enables us to provide a range of career opportunities, as well as benefits and rewards to enhance your well-being.
