As a Senior Software Engineer, you will design and develop scalable backend services, contribute to database modernization and migration initiatives, and help solve complex technical problems across our platform. Our backend services are primarily written in Go, but we welcome experienced engineers with strong expertise in another modern programming language who are interested in becoming proficient in Go.
What you will do
  • Design, develop, test, and maintain scalable backend services and APIs.
  • Lead or contribute to database migration and modernization projects.
  • Analyze existing applications and databases to identify dependencies, risks, and technical requirements.
  • Design and optimize PostgreSQL schemas, queries, indexes, partitions, triggers, and stored procedures.
  • Collaborate with engineers, architects, product teams, and other stakeholders to define and deliver technical solutions.
  • 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.
