What they need

Beacon Biosignals is seeking a Senior Software Engineer 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 a GraphQL API that enables scientific and clinical data use - distinct from frontend development or end-user product surfaces
You will lead the design and integration of new services and components for data and event processing, own the pipelines that deliver dataset snapshots into our warehouse, and collaborate with platform and application 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
You partner with product managers, scientific and clinical stakeholders, internal stakeholders, and other development and support teams to translate their requirements into new integrations, services, and solutions for scaling Beacon’s data platform
You implement features with attention to detail, demonstrating product awareness and high standards for data integrity, design soundness, and maintainability across the lifespan of the system
You draft RFCs to lead complex feature discovery and technical design phases, soliciting and incorporating input, and helping your team align on a set of decisions to guide development
You hold a high bar for correctness when data moves between systems: completeness, idempotency, and predictable behavior under partial failure
You leverage feedback from internal stakeholders and external partners to improve operational robustness and ease of use of the Datastore and its services via new documentation, tools, and dashboards- 5+ years of backend development experience, including at least 2 years focused on data platforms and backend infrastructure for data-centric applications - transactional systems, event pipelines, and the APIs that serve them
A self-directed approach, with a track record of thriving in hybrid or fully remote teams
Proficiency in Julia or Python
Experience with Julia is a strong plus, but not required - we welcome candidates eager to learn it!
A collaborative mindset - you enjoy working across disciplines and believe people achieve more together than alone
Experience deploying and operating services in containerized environments, with familiarity in Kubernetes and Infrastructure as Code (IaC) tools such as Terraform and/or Helm
Hands-on experience with data streaming and event processing, using Kafka (our event bus) or an equivalent such as RabbitMQ, Pulsar, or a cloud-based equivalent like Amazon Kinesis
Strong proficiency in SQL, with production experience working with PostgreSQL as an application database; you write and tune queries by hand and are comfortable reasoning about schema design, indexes, and query plans
Excellent written and verbal communication skills, especially in asynchronous and remote-friendly environments
Experience with GraphQL and TypeScript/JavaScript (Node.js); GraphQL is the Datastore’s primary interface
We don’t expect every candidate to check every box. If you bring strong fundamentals, care about data infrastructure for health, and are excited to learn, we’d love to hear from you!
