- Contribute primarily to the backend, with deep expertise in Node.js, and also to the frontend with React when necessary.
- Participate in architectural decisions, technical design, and the definition of implementation approaches.
- Collaborate within a SaaS product context, balancing delivery speed, quality, and technical sustainability.
- Operate with a high degree of autonomy in a small, senior squad that is highly accountable for its deliveries.
- Work closely with the team and the product context to ensure smooth integration and efficient execution.
Required Qualifications
- Solid experience in software engineering within a product context.
- Strong experience with Node.js.
- Experience with React on the frontend.
- Solid experience with backend systems architecture and development.
- Ability to contribute effectively in a full-stack context.
- Experience working autonomously in small teams.
- Excellent communication skills and maturity for decision-making.
Nice To Have Skills
