Top Software Engineer Jobs in San Diego, CA

Own end-to-end supplier integrations: design, implement, test, and monitor third-party APIs. Ship weekly, improve tooling and abstractions, ensure reliability, and mentor peers. Use AI-assisted workflows to speed integration development.

Build scalable simulation and planning systems for complex communications networks. Model hypothetical scenarios, allow users to vary configurations and assumptions, evaluate impacts, compare tradeoffs, identify risks, and integrate simulation capabilities into broader product workflows. The role involves full-stack engineering across design, development, testing, and operations, with emphasis on distributed systems, algorithms, network modeling, and computational reliability.

Build and operate AI agent systems with customer engineering teams, helping move prototypes into reliable production systems. Design agents, improve evaluations, monitoring, scaling, and reliability, and train customers on the Mastra framework. Translate recurring customer challenges into open-source framework improvements, fix performance issues, ship new primitives, improve code quality, and influence the product roadmap through production insights.

Lead an engineering team delivering automated month-end close pipelines for client accounting teams. Oversee ERP integrations, SQLMesh and DuckDB transformations, journal-entry outputs, controls, reconciliations, exception handling, and approval workflows. Maintain architectural boundaries across Elixir, Python, and platform components while converting bespoke client solutions into reusable capabilities. Manage technical roadmaps, multiple client engagements, engineering standards, and team development while partnering with accounting, delivery, technology, and product stakeholders.

Develop, test, implement, optimize, and maintain scalable software systems. Collaborate with product managers, designers, and engineers; troubleshoot technical issues; conduct code reviews; contribute to architecture decisions; follow secure coding practices; and participate in Agile ceremonies.

Build full-stack AI-powered video creation and collaboration tools, including rich multimedia interfaces, backend APIs, server-side processes, LLM-powered features, and conversational experiences. Work with generative AI, computer vision, and machine learning models in production. Improve system performance, reliability, and code quality while rapidly prototyping and delivering product features in a collaborative, high-ownership environment.

Lead development of high-performance Rust parsers, compilers, automata, indexes, and data structures for structured language-model generation. Optimize decoding-loop performance through profiling and benchmarking, integrate Python bindings and C++/CUDA components into inference engines, collaborate across teams, and maintain production-quality code through testing and CI/CD.

Lead customer implementations of healthcare data platform solutions by configuring the Smile platform, scripting, troubleshooting, designing technical solutions, and providing architectural guidance. Collaborate with customers and internal teams to deliver scalable, secure solutions, support technical analysts, contribute to RFPs, manage concurrent projects, and participate in on-call support.

Design, develop, and maintain secure integrations across NetSuite, Coupa, Leapfin, and other enterprise systems. Build iPaaS workflows, custom connectors, webhook and event-driven automations, bulk synchronization processes, monitoring, error handling, and retry mechanisms. Translate finance requirements into technical specifications and data mappings, support implementation projects, document architectures, and maintain audit readiness. Apply AI-powered tooling to automate finance operations while ensuring compliance, security, and reliable handling of sensitive financial data.

Lead multiple cross-functional engineering teams delivering monthly releases across Salesforce-centered modern platforms and legacy systems. Own delivery commitments, engineering standards, test automation, defect prevention, release quality, documentation, and federal compliance. Develop AI-native engineering practices, manage customer communication, flex team structures, and hire and grow technical leaders. The role requires maintaining zero escaped critical defects, high pre-UAT defect detection, rapid critical bug resolution, and stable modernization alongside legacy sustainment.
