Staff Software Engineer

Beacon Biosignals is transforming precision medicine for the brain, from clinical development to clinical care. The Staff Software Engineer will join the Datastore team, which defines the foundational data model and serves as the centralized repository and API for brain data collected from clinical studies. The role emphasizes the design and scaling of backend data infrastructure, distinct from frontend development or end-user product surfaces. The team is hiring two engineers: one focused on the breadth of the Datastore (event pipelines, GraphQL API, core data models, third-party integrations) and one focused on depth in PostgreSQL (data modeling, performance tuning, operations). The GraphQL API is generated from the PostgreSQL schema using PostGraphile, and row-level security is applied to effectively every table.

Responsibilities

Lead design and architecture for complex projects and systems within the Datastore; Design and scale backend systems for data infrastructure, including PostgreSQL data models, Kafka-driven event pipelines, and the GraphQL API; Own the pipelines that deliver dataset snapshots into the warehouse; Partner with product managers, scientific and clinical stakeholders, and other teams to translate requirements into integrations, services, and solutions; Debug and profile ambiguous problems that cross system boundaries; Draft RFCs to lead complex feature discovery and technical design phases; Plan own work and contribute to team planning; Teach and mentor other engineers; Leverage stakeholder feedback to improve operational robustness and ease of use of the Datastore

Requirements

7+ years of backend development experience, including at least 3 years focused on data platforms and backend infrastructure for data-centric applications: transactional systems, event pipelines, and the APIs that serve them; Highly proficient in at least one technical area relevant to this work: data modeling, distributed systems, API design, or database engineering; Strong proficiency in SQL, with production experience working with PostgreSQL as an application database; Hands-on experience with data streaming and event processing, using Kafka or an equivalent such as RabbitMQ, Pulsar, or 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; A track record of mentoring engineers and improving how a team works; A collaborative mindset; 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

Nice to have

Experience with Julia, a core Datastore language; Experience with, or interest in, using LLM-assisted or agentic coding tools in a production setting, with good judgment about guardrails; Experience with GraphQL and TypeScript/JavaScript (Node.js); Experience designing event-driven pipelines end to end, including producers, consumers, replay, and idempotency

Benefits

Equity; PTO; other benefits; Asynchronous, first-class remote work experience; Access to in-person office hubs in Boston, New York City, and Paris
