Top Senior Linux Jobs in San Diego, CA

Lead systems engineering for electronic and software-intensive defense systems. Provide technical direction, RF/data-link analysis (link margin, cascade), architecture and risk mitigation, algorithm development, proposal support, and cross-discipline coordination. Mentor teams and enforce systems engineering processes under program constraints.

Lead manufacturing engineering for renewable-energy product lines: optimize production, design processes and equipment, implement lean improvements, perform time studies, develop work instructions and training, support new facility layout, deploy automated production data collection, and collaborate with cross-functional teams to improve quality and efficiency.

Design, build, and operate high-throughput distributed data pipelines and platform infrastructure. Own end-to-end systems from architecture to production, write production-grade Python, optimize SQL at scale, architect service contracts, mentor engineers, and instrument systems for observability.

Lead process optimization for dairy production focusing on blending, standardization, heat treatment, filtration, and sanitation. Drive continuous improvement, capital projects, process capability studies, documentation (P&IDs, SOPs, CCPs), and food safety compliance (HACCP, GMP). Collaborate with operations, QA, maintenance, controls, and data science to improve yield, reduce waste, and minimize risk.

Create and check 3D models and 2D manufacturing drawings in SolidWorks, ensuring compliance with customer, ASME, and company standards. Collaborate with engineering, planning, and production to resolve conformance and manufacturability issues, perform interference checks, and produce fabrication-ready documentation.

Lead design and hands-on development of AWS-based serverless backend and IoT cloud services. Build Python Lambda microservices, REST APIs, telemetry pipelines, and secure AWS IoT Core device communication. Mentor engineers, define architecture patterns, ensure production readiness (monitoring, CI/CD, security), and guide cross-functional integrations and technical roadmaps.

Lead modernization of the WealthCare Administration platform by designing, developing, and deploying cloud-native microservices. Own full development lifecycle, build scalable APIs, leverage RDBMS/NoSQL and event-driven systems (Kafka/EventHub/ServiceBus), containerize with Kubernetes, and collaborate across teams to drive architecture and product evolution.

Provide process engineering support for polymers operations: troubleshoot plant issues, drive continuous improvement (yield, uptime, reliability, cost, safety), lead incident investigations and PHAs, manage capital projects, and support environmental compliance. Work involves reactors, exchangers, compressors, filtration, extrusion, and other chemical plant equipment. Travel under 10%.

Design and build payments workflows and PSP integrations (Stripe, Plaid). Own payment system architecture, collaborate across engineering teams to ensure seamless billing and reconciliation, apply AI to improve automation and accuracy, and mentor other engineers while shipping production-quality code.

Hands-on technical leader for Oracle Fusion Cloud ERP responsible for designing, developing, and optimizing extensions, integrations, reporting, and automation across Finance, Procurement, and Supply Chain. Lead architecture and solution design, ensure upgrade-safe and secure implementations, troubleshoot complex production issues, drive continuous improvement, mentor developers, and support governance within Agile/SAFe delivery teams.
