Top Tech Jobs & Startup Jobs in San Francisco, CA

Lead development of perception architecture for UAS seeker and world-modeling systems: design target detection/tracking/state estimation, fuse multi-sensor data (VIO/SLAM/target tracks), build ROS2/DDS interfaces, optimize C++ for embedded deterministic performance, support integration/HIL and mentor junior engineers while contributing reusable components to a shared AI/ML platform.

Build high-fidelity RGB and long-wave IR camera models and synthetic-data pipelines in Unreal Engine, stream sensor feeds to ROS 2, and generate labeled datasets and dynamic targets to validate perception, tracking, and Target State Estimation (TSE) software. Optimize rendering for real-time and headless simulation, manage 3D asset pipelines, and integrate perception sim into CI/CD for continuous evaluation.

Build and deploy LLM-powered applications, RAG systems, and agentic workflows; operate model serving and AI infrastructure on Kubernetes; integrate tools with identity and data-access controls; implement CI/CD, automation (Ansible/IaC), and observability; manage vector DBs, ingestion pipelines, and evaluation frameworks to deliver reliable, secure AI services for cross-company use.

Process semi-monthly payroll and maintain Paychex as system of record; manage multi-state tax registrations and POAs; administer garnishments and leave pay; reconcile payroll, support month-end close, maintain payroll records, and coordinate with HR, finance, and external providers while improving payroll automation and timekeeping processes.

Provide high-trust support to the Vice President by managing complex calendars, meetings, travel, and executive communications. Prepare agendas, board and investor materials, track action items, onboard senior hires, and coordinate cross-functional events. Maintain confidentiality, anticipate priorities, and improve executive operating cadence to enable efficient decision-making across programs and stakeholders.

Design, prototype, and deploy enterprise-grade internal applications and a custom ERP using AI-assisted tools. Build APIs, databases, dashboards, workflow automation, and third-party integrations while ensuring security, scalability, and maintainability. Rapidly iterate with stakeholders and establish development standards and deployment pipelines.

Design, implement, test, and maintain high-reliability, safety-critical application and utility software for UAS. Collaborate cross-functionally to build reusable tools, support build automation, system integration, scripting, CI/CD (GitHub Actions), and assist deploying software to AWS.

Lead design, development, and optimization of GNC systems for Group 1-4 UAS. Architect flight control software, run SWIL/HWIL simulations, develop Matlab/Simulink models, perform controls analysis, mentor engineers, lead flight test and R&D, and produce technical documentation.

Build and maintain backend integrations, front-end monitoring views, CI/CD pipelines, and infrastructure automation for UAS systems. Ensure monitoring, security, and performance optimization while collaborating with hardware and software teams and documenting best practices.

Build production-grade, responsive web dashboards and reusable UI components (React/TypeScript) for autonomy datasets. Create advanced visualizations (time-series, geospatial, 3D trajectories, real-time streaming), optimize frontend data flow and performance, design intuitive UX and design systems, connect to APIs/databases, perform client-side processing, and collaborate with data scientists and engineers to deliver analytics tools and reporting.
