Job Description

We are looking for a Staff Software Engineer to join a team undergoing technical and cultural transformation. A profile with experience and a cross-functional vision, capable of leading architectural decisions in the most complex systems and exerting influence beyond their own team.

You will join at a key moment. We coexist with established practices and new initiatives that we are progressively incorporating. We expect someone in this role to anticipate problems before they occur, know where to improve, and participate in the most difficult technical challenges.

Our engineering model is evolving toward practices such as Pair and Ensemble Programming, TDD, Clean Architecture, and CI/CD. We are looking for someone who knows these practices, understands their impact on development quality, and wants to help consolidate them.

RESPONSIBILITIES

Lead the architectural design of the most complex systems, providing long-term technical vision and judgment on decisions.
Identify and reduce technical debt and future toil in the components maintained by the team.
Provide technical feedback on projects relevant to their area, contributing to better results beyond their own work.
Act as a technical reference for high-priority problems and situations, resolving them and helping the team understand how to avoid them in the future.
Collaborate with different teams and profiles to ensure objectives are aligned and initiatives advance with technical consistency.
Ensure the quality of the code and the development process: reviews, clear standards, and constructive resolution of technical differences.
Work with engineering best practices: automated testing in its various forms (unit, integration, E2E), pairing, and judicious refactoring.
Maintain and improve CI/CD pipelines and migration automation.
Manage deployments and infrastructure with Kubernetes and Terraform, preferably in Azure.
Contribute to system resilience: monitoring, alerts, SLOs/SLIs, incident management, and operational documentation.
Clearly communicate technical decisions and context to very different profiles: from Product Managers, Project Managers, and Implementation Specialists to technical teams such as Platform or Mobile, adapting the message to each audience.
Mentor team members, including senior profiles, helping them develop both technical skills and strategic thinking.
Integrate AI tools and practices throughout the development flow—from design and documentation to testing and deployment—including agentic use to automate parts of the cycle.

REQUIRED EXPERIENCE/SKILLS

Solid technical experience and systems vision. We use .NET and Vue, but we value experience with similar stacks; the important things are the fundamentals and the ability to solve difficult problems.
Proven track record in web application development, having led relevant projects from start to finish.
Knowledge of relational databases and SQL. We use SQL Server and PostgreSQL, but we value any experience with relational databases or other approaches such as columnar.
Experience in developing and consuming REST APIs applying design best practices.
Experience with automated testing (unit, integration, E2E) and the ability to extend that culture to the rest of the team.
Solid experience in CI/CD and deployment automation.
Comfort working with legacy code: knowing how to read the context, adapt, and refactor with judgment when necessary.
Practical mastery in at least one specialized area beyond pure development, such as monitoring and observability, performance optimization, or integration testing at scale.

Preferred:

Experience in cloud environments (preferably Azure), with practical mastery of Kubernetes and Terraform integrated into CI/CD pipelines.
Familiarity with geospatial data, map visualizations, or interactive graphics.
High level of English for reading and writing technical documentation and participating in conversations with international teams.
Real practice with AI tools as a regular part of work, including agentic use to automate parts of the development cycle.

EDUCATION

Education or certifications in Computer Science, Computer Engineering, Systems Administration, or Software Development.
English certifications will be valued.

BENEFITS

Competitive annual salary.
Health insurance and a flexible remuneration plan so you can adapt part of your compensation to your needs.
Annual bonus based on individual performance and company performance.
Flexible schedule.
Remote work options.

At Technosylva, we value diversity of experiences and skills, and we understand that every trajectory is unique. Therefore, we invite all people who consider themselves to meet most of the requirements and are interested in developing and contributing in this position to apply.

DISCLAIMER

The finalization of salary and benefits depends on a multitude of factors including: location, experience, training, qualifications, and market demands.

INCLUSION COMMITMENT

Technosylva is an equal opportunity employer. We are committed to creating an inclusive environment where different perspectives contribute to better solutions.
