Senior Backend Engineer - Core Java & Systems Integration
About The Position
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. 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.

- Able to commute daily to our San Carlos, CA headquarters for a 100% on-site schedule.
- 5+ years of professional backend software development experience in a production environment.
- Elite proficiency in Java and the Spring Boot ecosystem (Dependency Injection, Spring Data, Transaction Management).
- Hands-on experience operating containerized workloads on cloud infrastructure (strictly GCP/GKE preferred) utilizing message brokers like RabbitMQ or Cloud Pub/Sub.
- Deep knowledge of relational databases (MySQL), including schema design, constraint invariants, query tuning, and indexing strategies.
- A strict affinity for writing comprehensive unit and integration tests (JUnit, Mockito, TestContainers) as a mandatory definition of "done."
Nice To Haves

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