Full Stack Developer & System Administrator

Technesthai is an Italian technology consulting firm that positions itself as the technological partner of choice for organizations pursuing successful digital transformation. We combine Custom Software Development, Data Science & AI/ML solutions and IT Consulting to help mid-to-large enterprises modernize their technology stack, leverage data analytics and remain competitive in fast-evolving markets.

Our work is guided by three pillars — Innovation, Quality and Collaboration — and by a consultative approach that prioritizes understanding the specific needs of each client over standardized implementations. We design, build and own end-to-end solutions for our clients — from initial discovery through architecture, implementation and long-term evolution — and we invest continuously in R&D and team training to stay at the forefront of emerging technologies and methodologies.

We are looking for a Full Stack Developer & System Administrator to join our team!

We are looking for a versatile engineer comfortable across the entire technology stack — from designing modern web applications and REST APIs to provisioning, monitoring and securing the environments those applications run on. You will join one of our cross-functional delivery teams, working alongside developers, analysts and architects to build and evolve solutions that we design, deliver and maintain end-to-end. As a mid-level professional, you will be expected to take ownership of features end-to-end, contribute to architectural decisions and support junior colleagues.

• Design and implement effective RESTful APIs and secure authentication flows based on OAuth / OIDC
• Model and maintain relational databases, ensuring data integrity and query performance
• Containerize applications with Docker and contribute to CI/CD pipelines for automated build, test and deployment
• Manage and monitor cloud and on-premises environments, ensuring system availability, performance and security
• Apply clean architecture principles (SOLID, DRY, Dependency Injection) and guarantee adequate test coverage with unit and integration tests
• Collaborate with functional analysts and business stakeholders within the project team, translating requirements into reliable software
• Share knowledge, support junior colleagues and contribute to the continuous improvement of team practices
