Software Engineer (Datastore)

About this role

• Beacon Biosignals is seeking a Software Engineer IV to join our Datastore team
• The Datastore sits at the heart of Beacon’s platform
• It defines our foundational data model and serves as the centralized repository and API for brain data collected from clinical studies, supporting the analytical tools, services, and applications used by our scientists, clinicians, and partners
• This role emphasizes the design and scaling of backend systems for data infrastructure: PostgreSQL data models, Kafka-driven event pipelines, and the GraphQL API that makes scientific and clinical data usable - distinct from frontend development or end-user product surfaces
• At this level you will lead the design of complex systems within the Datastore rather than individual components, own the pipelines that deliver dataset snapshots into our warehouse, and collaborate across platform, application and scientific teams to implement APIs that unlock new workflows in Beacon’s expanding portfolio of clinical studies and digital health products
• You should expect to write SQL by hand, and to reason about schema design, indexes, and query behavior as a matter of course
• What success looks like:
• You lead design and architecture for complex projects and systems within the Datastore, weighing implementation trade-offs with engineering principles and backing your decisions with data rather than preference
• You partner with product managers, scientific and clinical stakeholders, and other development and support teams to translate their requirements into new integrations, services, and solutions for scaling Beacon’s data platform - contributing to broader product and technical decisions, not simply implementing them
• You debug and profile ambiguous problems that cross system boundaries, including codebases beyond the Datastore’s purview, and you leave what you touch better than you found it — structure, test coverage, tooling
• Peers look to your work as an example: you implement features wi...
