About Clear Labs

Clear Labs harnesses the power of next-generation sequencing (NGS) to simplify complex diagnostics for clinical and applied markets. By creating a fully automated platform that brings together DNA sequencing, robotics, and cloud-based analytics, Clear Labs democratizes genomics applications to deliver clarity. Our turnkey platform accelerates outcomes and improves accuracy from food-borne pathogens to infectious diseases.

The Opportunity

We are looking for a hands-on Senior Backend Software Engineer to join our lean, high-impact engineering team as a core platform owner. This role is a critical replacement for a key team member and focuses exclusively on the "connective tissue" of our platform—architecting robust Java backend services and low-latency integration bridges between physical lab automation hardware and our cloud ecosystem.

This is an opportunity for a purist backend systems engineer. You will own the deterministic state machine that ensures our physical robotics and cloud orchestration layers operate in perfect synchronization.

Primary Responsibilities

Core JVM Service Development: Own, develop, and maintain a distributed matrix of 30+ microservices using Java and Spring Boot.
Systems Integration: Analyze, design, and build bulletproof, replay-safe API integrations between Clear Labs, external bioinformatics analysis pipelines, and clinical middleware (LIMS/EHR).
State Orchestration & Messaging: Drive architectural resilience using Domain-Driven Design (DDD) principles, leveraging Google Kubernetes Engine (GKE), RabbitMQ, and GCP Cloud Pub/Sub for asynchronous event streaming.
Data & Performance Engineering: Optimize and harden existing transactional database services (MySQL, Redis) for extreme reliability under high concurrency and massive data scale.
On-Market Tier Support: Act as the high-level technical lead for production escalations, triaging and troubleshooting deep infrastructure bugs within our grid service layers.
Compliance & Hardening: Implement technical security controls as we advance toward SOC2 and ISO 27001 compliance standards.

Infrastructure & Messaging: Hands-on experience operating containerized workloads on cloud infrastructure (strictly GCP/GKE preferred) utilizing message brokers like RabbitMQ or Cloud Pub/Sub.
Databases: Deep knowledge of relational databases (MySQL), including schema design, constraint invariants, query tuning, and indexing strategies.
Testing Philosophy: A strict affinity for writing comprehensive unit and integration tests (JUnit, Mockito, TestContainers) as a mandatory definition of "done."
