We provide isolated runtimes for executing untrusted code, mostly generated by LLMs. Our sandboxing is powered by a combination of WebAssembly, V8, and microVMs. Our customers do things like extract data from log lines at run time by asking claude-3-7-sonnet to generate a parsing function on-the-fly and then sending it to us for execution.
Things we need help with:
- Our API (https://docs.riza.io/) (Postgres / Go)
- Our account dashboard (Postgres / Go / React / TypeScript)
- Our code execution engine (Go / Rust)
- New products including code generation workflows (Anthropic / OpenAI experience a plus)
We’ve raised seed money, but the whole company is currently just me, Andrew and David working out of a converted warehouse on Alabama St. We’re second-time founders, so we know the risk we’re asking you to take and we’re prepared to compensate accordingly.

With recent technologies such as WebGPU and WebAssembly, the browser is quickly becoming a powerful gaming platform. High-quality 3D graphics and near-native level performance are becoming possible without the need for downloads, apps, or platform-specific development. Our browser games platform is already reaching more than 40 million people per month. We are self-funded, profitable, remote-first, and fast-growing.
We are currently looking for multiple people to bring our product, engineering, and marketing to the next level.
Please note that we're looking for people who can work on a European timezone and are ideally based in Europe (which includes the UK for those in doubt).

We are currently looking for a driven, entrepreneurial founding/Staff engineer. If you're interested in working in a small startup, bringing stuff from 0 to 1 and you want to have an outsized impact on product & tech, this is the right place for you. FoodFacts is a B2B startup specialized in CO2 calculations for Food (as the name suggests ;). We're currently operating only in Sweden but we have plans to move out into other european countries. We're currently already working with all swedish food retailers and prodive carbon estimations on all food products sold in Sweden. The goal of this partnership is to steer assortments but also consumers towards a more climate-friendly food consumption. We're also working with a bunch of food producers in Sweden as part of a pilot project to influence the food-product creation in an early stage towards more sustainable and profitable products.
The systems you’ll work in full-stack Typescript (Node.js on the backend and React on the Frontend) running partially on AWS and Vercel. Postgres and MySQL as our DBs.
This IS for you if: - You like to work directly with customers and end-users. - You have an entrepreneurial mindset: you want to influence the direction of tech & product and are comfortable with uncertainty.
This is NOT for you if: - You expect processes to be fully set for everything - You only want to work with [insert specific technology]
We don't sponsor visas and you have to already have a working permit for Sweden and be in the country. Apply here: https://tally.so/r/3l4z85
I'm hiring an AI/ML engineer to join the AI/ML team at FinQuery.
Our team creates services powered by LLMs and traditional ML to enable features across our suite of products. Like many companies, we are trying to separate the real value of the latest AI techniques and tools from the hype (agents?), and unlocking use cases that actually benefit our customers. This role is a rather generalist role for someone with a strong ML background, 2+ years of work experience (post schooling), and a desire to work on both proof of concept and production systems. You would be joining our small AI/ML team as we continue to automate as much as possible and enable new product features and use cases.
FinQuery makes software to help companies comply with new lease accounting regulations, manage financial contracts, and keep track of recurring and one-off payments. We're based in Atlanta, but support fully remote employees in the US. This is an IC role.
We are also hiring for roles in DevOps, marketing, and more.
We’re building an AI system for analysts and scientists, based on a fundamentally new approach to reasoning and knowledge representation. Our approach goes beyond state-of-the-art LLMs by combining algorithms in symbolic ways, to provide novel capabilities like performing multi-step analysis, displaying a verifiable reasoning path, and assessing uncertainty. We envision applications supporting and automating analysis and research in domains such as Finance, Strategy Consulting, Engineering, Material Sciences, and more.
Want to contribute to cutting-edge work in AI? We’re looking for:
* Senior Program Synthesis Engineers
* Senior NLP Engineers
* Finance & Operations Manager

We’re a remote-first company building cutting-edge Kubernetes solutions and cloud-native software.
Now, we’re looking for a DevOps Engineer who loves Linux, thrives in infrastructure, and wants to be more than a script-writer.
- You’re deeply passionate about Linux, servers, and containerized infrastructure.
- You understand Kubernetes well, or you're eager to master it — not just as a deployment tool, but as a platform.
- You can write real code — ideally in Golang (or are keen to learn it).
- You care about doing things the right way: clean architecture, reproducible systems, and well-maintained infrastructure.
- You hate duct-taped systems — if your idea of DevOps is gluing things together with Ansible and Bash scripts, please don’t apply.
We understand that it's hard to have all the above requirements. We encourage you to apply even if you are missing one or two but still think you would be a fit.
What you’ll do:
- Maintain, troubleshoot and implement new features in our Kubernetes platform.
- Deploy and configure workload in Kubernetes clusters for our clients and our own product.
- Help build and extend Kubernetes Operators and infrastructure components in Golang.
- Join consultation projects where your infrastructure expertise makes a real difference.
- Collaborate with a globally distributed team that values clean, well-thought-out solutions.

PermitFlow’s mission is to streamline and simplify construction permitting in the $1.6 trillion United States construction market. Our software reduces time to permit, supporting permitting end-to-end including permit research, application preparation, submission, and monitoring.
We’ve raised a $31m Series A led by Kleiner Perkins with participation from Initialized Capital, Y Combinator, Felicis Ventures, Altos Ventures, and the founders and executives from Zillow, PlanGrid, Thumbtack, Bluebeam, Uber, Procore, and more.
Permitting is a challenging yet interesting problem; thousands of municipalities across the United States have their own processes and requirements - many which are continually updating. Software, AI, and LLMs provide an exciting opportunity for us to reason at scale and distill a nuanced and localized permitting process into a standard and streamlined experience for our customers.
We're looking for customer-obsessed, ambitious, and hard-working teammates who are excited about solving a real-world problem with technology at its helm.
