• Support technical project planning, including effort estimation, solution design, and resource allocation.
• Partner with the Sales and Business Development teams to prepare technical proposals, ensuring proposed solutions are technically sound and aligned with client needs.
• Identify opportunities for technical improvements and innovation across projects.
• Mentor software engineers at different experience levels, fostering technical growth and engineering excellence.
• Promote knowledge sharing through technical training, architecture discussions, and lessons-learned sessions.
• Contribute to engineering knowledge management by defining and maintaining technical standards, best practices, documentation, and development guidelines.
• Collaborate effectively with both technical and non-technical stakeholders, translating business requirements into scalable software solutions.

Required Qualifications

• Experience with relational databases such as PostgreSQL, MySQL, or Microsoft SQL Server.
• Strong experience writing high-performance SQL queries and optimizing data access.
• Advanced knowledge of Git, including branching strategies, pull requests, and code review workflows.
• Experience with CI/CD pipelines using tools such as GitHub Actions, GitLab CI, or Azure DevOps.
• Experience with modern software architectures, including:
• Docker containers
