  • Ensure data integrity, security, reliability, and performance throughout the software-development and migration processes.
  • Use AI-assisted development tools responsibly to improve design, implementation, testing, documentation, and troubleshooting.
  • Participate in code reviews, architectural discussions, production support, and mentoring of other engineers.

What you will need to have
  • 7+ years of professional software-engineering experience.
  • Strong experience developing production backend systems in Go or another modern programming language.
  • Ability and willingness to become productive in Go.
  • 5+ years of experience with relational databases, including database design, optimization, and data-migration techniques.
  • Strong PostgreSQL experience or comparable experience with another enterprise relational database.
  • Experience with query optimization, indexing, data modeling, partitioning, triggers, and stored procedures.
  • Experience operating applications or databases in a cloud environment.
  • Practical experience using AI-assisted development tools while independently validating generated output.
  • Strong analytical, troubleshooting, communication, and collaboration skills.
  • A passion for technology, continuous learning, and solving complex engineering problems.
  • Bachelor's degree in computer science, engineering, or a related field, or an equivalent combination of education, professional experience, and/or military experience.

What would be great to have
  • Production experience developing backend services in Go.
  • Advanced PostgreSQL experience, including PL/pgSQL, replication, high availability, or performance tuning.
  • Experience with cloud-native architectures, containers, Kubernetes, microservices, or distributed systems.
  • Experience with change data capture, database replication, or large-scale data migrations.
  • Experience with performance and load testing.
  • Experience with specification-driven development, including translating requirements into technical specifications, implementation plans, and automated tests.
