Mission

SEGULA Technologies, a global leader in high-value Engineering and Consulting services with over 15,000 engineers across more than 30 countries, is looking for a SENIOR FULL STACK DEVELOPER to join our project team based in Aveiro, Portugal, with work on-site.

You will join a transformation and industrialization project for a digital platform serving the automotive industrial sector, evolving an existing solution toward a global cloud-native architecture deployed on Google Cloud Platform (GCP).

Responsibilities:

• Develop and maintain frontend (Angular) and backend (NestJS/Node.js) features, with full ownership of technical design decisions.
• Lead database optimization and tuning efforts, including migrations and complex query improvements.
• Identify and resolve performance bottlenecks across the application's data flows.
• Work in parallel across different functional modules, coordinating with the rest of the team and providing technical input on architecture decisions.
• Actively contribute to API standardization (REST/API-first) and middleware integration.
• Help drive code quality, modularity, and maintainability as part of an ongoing refactoring effort on an existing solution (not a greenfield build).
• Support and mentor junior team members on development best practices.

Profile

Requirements:

• Degree in Computer Engineering, Software Development, or a related field.
• At least 4-5 years of Full Stack development experience, with strong command of Angular (17+) and NestJS/Node.js.
• Solid experience with PostgreSQL and relational database optimization in production environments.
• Prior experience with cloud architectures (GCP) and containerized deployments (Docker/Kubernetes).
• Advanced knowledge of testing best practices (unit, integration, e2e).
• Ability to work autonomously and contribute technical judgment to architecture decisions.
• Full professional fluency in English (all corporate reporting, project governance, and documentation are strictly in English).
• Based in or near Aveiro, or available to relocate and work on-site.

Nice to have:

• Experience with Apigee or other API management tools.
• Familiarity with event-driven architectures (Solace or similar).
• Experience leading or contributing to refactoring projects on existing systems.
• Knowledge of Portuguese, Spanish, or French to smooth local collaboration at the Aveiro plant.
