We’re Quadrature, a technology company in the algo trading space. We use advanced machine learning on large amounts of data to predict trends in financial markets. More at https://quadrature.ai.
What makes us different:
- ~250 people, no traders — our systems trade autonomously.
- Single PnL.
- We don’t separate “quant researchers” from “developers” — everyone codes to a high level and has the opportunity to do research.
- Mission-driven: our climate foundation (https://www.qc.foundation/) has made significant divestment commitments over recent years. For many of us, it's why we're here.
We’re hiring Quant Developers — a generalist team of engineers and researchers who own both the research pipeline and software infrastructure across the entire business. Stack is Rust, Python and C++. We want sharp, collaborative people with no big egos.
Interested? Reach out here: li@qc.ai.
We build and deploy self-driving industrial vehicles - forklifts, tuggers - to real warehouses and factories across North America. Not a research lab, not a demo: our AVs are running production routes at customer sites today. Publicly traded (CYN), ~100 people, startup energy.
The stack touches everything from low-level C++/ROS2 on the vehicle to a Python + TypeScript cloud platform (fleet dashboards, real-time telemetry, digital twins, analytics). If you want to work on software that moves physical things in the real world, this is it.
Currently hiring across engineering, product, field ops, and business:

We have a ton of smart people trying to solve the autonomy problem in warehouses for retrofitting processes. Come and join!
We are hiring two Product Engineers to join us in our newly opened office in SF. We're small and early and you'll help shape team culture.
Kinelo solves "context myopia": autonomous and semi-autonomous AI agents don't know what they don't know, so they can't search or find the background information required to accomplish tasks accurately and effectively. The result looks like slop but it's not due to model performance, more due to workflow integration. From there, we're rapidly moving into organizing humans together with autonomous "AI coworkers" into workflows that span both. Our goal is to change how organizations are run and structured.
Our #1 hiring criteria for this position is immense software wisdom, the kind not yet encoded in the weights of an LLM. We are not looking for artisans to meticulously craft single lines of code. We're looking for software engineers excited to use the leverage that AI offers for code production to permit focus on higher order technical architecture, product requirements, and user needs.
We're looking for enough experience that indicates accumulated wisdom in shipping and maintaining reliable, scalable software, solid CS fundamentals, experience taking products from 0 to 1, and versatility.
Our current tech stack includes TypeScript, a managed container service, Postgres, and Redis. But we are adaptive and you should be too. We highly value software engineering and computer science fundamentals and experience with other languages like Go, C++, Python is valued.
Competitive salary, meaningful (~first batch of hires) equity, founder previously exited to Apple, strong fundraising history (~$10m).
Please email us at jobs@kinelo.com. If you want to stand out, tell us how you think the job of a software engineer is changing. There's also a full JD here: https://job-boards.greenhouse.io/kinelo/jobs/4205846009
A software engineer today has Claude Code and Cursor. A mechanical engineer designing the next jet engine? Still searching Excel sheets and asking whoever has been around longest.
We're building the AI co-engineer for physical products - in production with major European manufacturers. Working at the intersection of 3D, reasoning, and long-horizon agents.
Stack: Python, TypeScript, multi-agent orchestration, LLM integrations. Recent work includes a custom multi-agent SDK for durable long-horizon execution and a production pipeline wrapping a C++ CAD SDK.
We are a small team and you own hard problems end-to-end. We offer a competitive salary + early equity.
Full JD: https://www.notion.so/Founding-Staff-Engineer-31b21f51314080...
If this sounds interesting, send your CV to hiring@3ive.ai and the answer to the following question: "What is the hardest technical problem you have owned end-to-end, what made it hard, and what did you learn?"
We're building a computational geometry engine from scratch in C++20. B-Rep modeling, surface-surface intersection, tolerance-aware geometric algorithms, and next-gen data exchange formats like QIF and STEP AP242. Clean codebase, no legacy code, no C++98.
If you've worked on a geometry kernel, CAD internals, or computational geometry libraries, you know how rare it is to find a modern codebase in this space. We're looking for someone who has actually implemented or worked closely with things like half-edge data structures, NURBS/spline evaluation, parametric surface operations, or spatial indexing for geometric queries. Experience with ACIS, Parasolid, or OpenCascade is a strong signal.
Huge bonus if you understand GD&T, tolerancing, or model-based definition well enough to implement it, not just read a drawing. The intersection of manufacturing domain knowledge and C++ engineering skill is exactly what we're building for.
Small team, early stage. Every engineer has real influence over architecture and technical direction. This is also a customer-facing role: you'll participate in demos and technical conversations with enterprise customers, so communication skills matter.
Requirements: modern C++ (C++17/20), US citizenship (required for government CUI work).
$95K–$125K base + performance bonuses, health insurance, 401k match, home office budget, professional development budget. Fully remote, US time zones.
