Top Linux Jobs in San Diego, CA

As a Backend/AI Engineer, you'll integrate LLMs, optimize document processing pipelines, and improve API design for document understanding tasks.

Build Valius’s technical foundation across full-stack applications, cloud infrastructure, data pipelines, and patient molecular data systems. Partner with founders and computational biologists to set technical direction, develop AI-powered interfaces, manage architecture and security, and deliver reliable, well-tested software. The role requires ownership from design through deployment and offers opportunities for future technical leadership.

Design, deploy, validate, and troubleshoot Linux-based HPC systems, GPU platforms, enterprise servers, and cluster environments. The role includes hardware and software integration, performance testing, system documentation, customer deployments, configuration review, technical support for sales, and resolving system-level issues. Candidates will also evaluate new technologies, analyze system performance, and recommend improvements to stability, efficiency, and scalability.

Owns assembly, testing, quality, inventory, and shipping processes for benchtop CNC wire-forming machines. Improves production efficiency through lean methods, time studies, capacity planning, root-cause analysis, and process documentation. Supports prototype-to-production transitions, supplier quality, technician training, sales demonstrations, customer installation and training, troubleshooting, maintenance, and field issue resolution. Requires hands-on electromechanical manufacturing experience, CAD proficiency, quality-system knowledge, and strong communication skills.

Design and verify superconducting electronic circuits for AI hardware, including Josephson junctions, SQUIDs, superconducting nanowire detectors, and thin-film amplifiers. Adapt circuits for advanced fabrication processes, support electromagnetic and post-layout simulation, develop Python-based layout flows, expand device-primitives libraries, and collaborate with fabrication, foundry, algorithms, and measurement teams to execute successful chip tapeouts.

Designs aerial and underground outside plant fiber optic and copper telecommunications networks, including FTTH and GPON systems. Creates system designs, bills of materials, schematics, construction quotes, and network growth plans. Performs field checks, site walks, quality control, record interpretation, and construction support while collaborating with engineering, design, power, and construction teams. The role is primarily home-based with occasional travel and may transition to office-based work in Florence, Kentucky.

Build, deploy, and operate reliable compute infrastructure and services across customer on-premises and cloud environments. Design air-gapped deployments, manage Kubernetes platforms, improve scalability and availability, troubleshoot distributed systems, optimize constrained resources, write tests, document operations, and participate in on-call rotations. Collaborate with engineering teams and customers to support satellite operations and image-processing platforms.

Maintains operability, configuration management, technical baselines, and lifecycle management for assigned nuclear facility structures, systems, and components. Performs system testing, performance monitoring, assessments, operability evaluations, maintenance planning, failure trend analysis, and procedure development. Supports waste processing operations, facility changes, equipment testing, troubleshooting, and compliance with DOE orders, safety-basis requirements, and nuclear industry practices.

Develop control algorithms and high-fidelity plant models for autonomous battery-electric rail vehicles. Build simulation infrastructure, including MIL, SIL, HOOTL, and HIL environments, to verify software before hardware deployment. Tune and validate controllers, derive sensor and actuator requirements, correlate simulations with test data, support vehicle integration and testing, and improve reliability, safety, and performance of real-time control software.

Designs, operates, and continuously improves cloud-based enterprise systems in AWS. Responsibilities include resolving complex system issues, implementing infrastructure automation, managing system performance and security, supporting change and incident processes, maintaining infrastructure as code, improving monitoring and recovery readiness, planning capacity, documenting procedures, and guiding less-experienced engineers.
