Staff Power Electronics Engineer
Karman Industries, a Torrance-based startup building zero-water thermal cooling systems (the HPU) for AI data centers, is hiring a Staff Power Electronics Engineer to design, simulate, and qualify high-voltage (13.8kV+) power conversion and distribution systems, including PCB design, SIL/HIL modeling, and hands-on integration of high-power hardware on product skids.
Senior Embedded Systems Engineer
Senior Embedded Systems Engineer at Karman Industries, a Torrance (LA) startup founded in 2024 building thermal cooling hardware (the HPU) for AI datacenters. Day to day: design control electronics and embedded software for LV/MV power conversion, including SiC devices, grid-forming bidirectional controls, and HIL-based validation.
(Senior) AI Engineer - Kotlin, Java, TypeScript (m/w/d) (KI-Engineer)
A technical-generalist AI engineer at an AI/autonomous-systems startup in Munich, working directly with the CEO to clear technical blockers across the whole stack: building Kotlin backend and TypeScript frontend features, integrations, and prototypes, while using AI tools like Claude Code and agentic workflows daily.
Senior Full-Stack Engineer (m/w/d) – Hamburg (Fullstack-Entwickler/in)
Builds product features end to end for Decisity, an AI-native platform in Hamburg that turns briefs and documents into board-ready strategy decks: developing the TypeScript/React/Next.js web app, working on Python services for document ingestion and analysis, and running the platform on Google Cloud. Hybrid: Hamburg office plus remote days.
ML Engineer
Machine Learning Engineer at Freed (San Francisco, on-site), building and scaling the production ML systems behind AI tools that reduce clinicians' administrative burden. You'll develop and deploy models, build ML pipelines and evaluation frameworks, and improve reliability of AI features — Python and modern ML frameworks core; LLM/generative-AI experience a plus.

Staff Systems Engineer, Software
Staff software systems engineer who architects and implements the software infrastructure coordinating precision manufacturing equipment, distributed control systems, and robotics at Atomic Machines. Day-to-day spans system architecture, APIs and distributed services (gRPC, REST, IPC), and hands-on development in languages like C++, Rust, or Go.
Senior/Staff Electrical Engineer, Test
Senior/Staff Test Development Engineer at Atomic Machines owns end-to-end test strategy and builds custom instrumentation—PCB design, C microcontroller firmware, and mechanical fixtures—to validate novel micromachines made on its Matter Compiler robotic manufacturing platform. Core skills: analog/mixed-signal circuit design, instrumentation, error budgets, and first-principles test development.
Partnerships Solutions Engineer
Partnerships Solutions Engineer at Dust (an enterprise AI agent platform) builds the US partner ecosystem: co-creating packaged AI solutions, implementation playbooks, and reference architectures with consulting/tech partners, and leading demos, workshops, and proofs of concept. Core work spans Dust's APIs, MCP ecosystem, agents, and integrations; office-first in New York.
Generative AI CAD Engineer
Build generative AI-driven CAD pipelines to automate design of micromachines, using Python/Rust and CAD APIs to assemble and optimize 3D assemblies from parametric components.
Registered Dietitian Nutritionist
Remote contract role for a Registered Dietitian Nutritionist delivering virtual care in obesity medicine and related specialties like dermatology and mental health using telehealth tools.
Technical Program Manager, Manufacturing Operations
Technical Program Manager responsible for the Integrated Master Schedule (IMS) for key programs and products, serving as the central integrator between program, manufacturing engineering, supply chain, and operations timelines in an autonomous factory environment that combines AI, advanced software, robotics, and full-stack manufacturing.
Member of Technical Staff - ML Ops
Vinci builds an AI foundation model that learns physics from self-generated simulation data. This ML Ops engineer owns the petabyte-scale data pipeline end to end: scaling GPU job scheduling and execution (Temporal + Ray), dataset lineage, quality checks, and training-run launch, checkpointing and model registry.
Senior/Staff Infrastructure Engineer
Infrastructure engineer (senior/staff) at a stealth AI startup incubated by a top Silicon Valley VC, architecting backend and distributed systems that turn enterprise email into real-time, queryable intelligence for large organizations. In-person only role; deep backend/distributed-systems fundamentals required, Python or TypeScript a bonus.
