Proven ability to design and deliver complex, multi-service backend systems in a collaborative engineering environment.
Experience working on monolith-to-microservices transitions, including service extraction and maintaining backward compatibility.
Strong knowledge of PostgreSQL, including schema design, query optimization, and performance tuning.
Solid understanding of API design (REST and/or gRPC) and distributed system architecture.
Experience with asynchronous systems such as background jobs, message queues, or event-driven architectures.
Familiarity with containerization and orchestration tools such as Docker and Kubernetes.
Understanding of CI/CD pipelines, deployment workflows, and modern observability practices (logging, metrics, tracing).
Strong communication skills with the ability to explain technical concepts to both technical and non-technical stakeholders.
Comfortable working autonomously in a remote-first, fast-paced engineering environment.
Benefits:
Competitive salary range of $175,000–$185,000, based on experience and location.
