A Boston-based life sciences venture firm is building a genomic sequencing and consumer health data platform, and is looking for a Backend Engineer to architect and build the platform's backend from scratch.
The platform is a new spinout that will bring genomic data, wearable data, lab results, and health records into one consumer product. It is at the pre-product stage, and an experienced frontend lead has just joined as the first technical hire.
The Backend Engineer is the second technical hire and works directly with the frontend lead and the firm's leadership. Day to day, the role covers API design, data pipelines for large genomic inputs, PostgreSQL data models, and AWS infrastructure. Success means sharing API contracts and data shapes with the frontend before build starts, and delivering pipelines that are reproducible and recoverable. The engagement starts as a contract through Pearl and converts to full-time employment once the company is fully established.
Backend Services & APIs

and maintain RESTful APIs using Node.js, TypeScript, and Fastify.
Define API contracts and data shapes with the frontend engineer before implementation.

Build backend services that handle large-scale data requests securely and reliably.
Data Pipelines
Develop reproducible, recoverable pipelines for large, inconsistent genomic data inputs.
Optimize pipeline performance as data volume grows.
Database & Cloud Infrastructure
Design PostgreSQL schemas and data models for genomic and health data.
Architect AWS infrastructure using infrastructure-as-code (CDK or CloudFormation).
Set up secure storage systems for sensitive healthcare data.
Collaborate with the frontend engineer on deployment workflows.
Security & Data Governance
Implement role-based access controls and data encryption for sensitive health data.
