About The Position

We are seeking a GCP FHIR API Staff Data Engineer to design, develop, maintain, and support custom-built HL7 FHIR APIs on Google Cloud Platform. This role will focus on reading large-scale clinical data from Google Cloud Bigtable, transforming it into FHIR-compliant resources, and exposing it through high-performance, secure REST APIs for downstream consumers. This role requires working closely with data teams, frequently in a matrixed environment as part of a broader project team.

This is a hands-on engineering role requiring deep experience in custom API development, healthcare data standards, and GCP-native services, with responsibility across the full API lifecycle—from design through production support. This role requires ‘self-starters’ who are proficient in API problem solving and capable of bringing clarity to complex situations.

Due to the emerging and fast-evolving nature of GCP technology and practice, the position requires that one stay well-informed of technological advancements and be proficient at putting new innovations into effective practice. As a Staff Data Engineer, you will collaborate closely with all team members to create a modular, scalable solution that addresses current needs, but will also serve as a foundation for future success.
