Senior Software Engineer

Beacon Biosignals is transforming precision medicine for the brain through at-home EEG and cardiopulmonary data platforms for clinical development, diagnostics, and care. The Senior Software Engineer will design and scale backend data infrastructure for the Datastore, including PostgreSQL models, Kafka-driven event pipelines, GraphQL APIs, and warehouse data delivery. The role also involves leading service integrations, ensuring data integrity, and collaborating with scientific, clinical, platform, and application teams.

Responsibilities:

• 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

Requirements:

• 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
• 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
• 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
• Proficiency in Julia or Python
• Experience deploying and operating services in containerized environments, with familiarity in Kubernetes and Infrastructure as Code (IaC) tools such as Terraform and/or Helm
• Experience with GraphQL and TypeScript/JavaScript (Node.js); GraphQL is the Datastore's primary interface
• 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
• A self-directed approach, with a track record of thriving in hybrid or fully remote teams
• Experience with Julia
