Principal Data Engineer

Beacon Biosignals is transforming precision medicine for the brain through at-home EEG and cardiopulmonary signal platforms for clinical development, diagnostics, and care. The Principal Data Engineer will guide the architecture and design of the Datastore, build scalable data models and event-driven pipelines, coach engineers and stakeholders, and establish engineering standards across Platform teams.

Responsibilities:

• You partner with engineering and product leaders and Datastore stakeholders to guide architecture and solutions for the Beacon Datastore, and influence architectural standards across Platform teams
• You implement features that model best practices, and coach team members to develop their skills. You hold the Datastore to ever higher standards for data integrity, design soundness, and maintainability as it grows
• You draft RFCs to lead complex feature discovery and technical design phases, soliciting and incorporating input and building alignment on the decisions that guide development

Requirements:

• 10+ years of backend development experience, including significant experience focused on data engineering, data platforms, and infrastructure for data-centric applications
• Strong proficiency in SQL, with production experience working with PostgreSQL
• Proficiency with data streaming and event processing, using tools such as Kafka, RabbitMQ, Pulsar, or a cloud-based equivalent like Amazon Kinesis
• Strong proficiency in a modern general-purpose language; proficiency in the Datastore's specific stack (SQL/TypeScript/Julia) is not required, but you should be able and excited to learn quickly!
• Experience with, or interest in, using LLM-assisted or agentic coding tools in a production setting, with good judgment about what guardrails are needed
• Experience deploying and operating services in containerized environments, with familiarity in Kubernetes and Infrastructure as Code (IaC) tools such as Terraform and/or Helm
• A collaborative mindset - you enjoy working across disciplines and believe people achieve more together than alone
• Excellent written and verbal communication skills, especially in asynchronous and remote-friendly environments
