Most legacy software has no API and cannot be automated with Agentic AI. At our company builder (schub.tech) we had the same problem in one of our ventures and build ourselves a solution: based on computer-use, we can insert & extract information out of any software.
We believe this toolstack is useful to many others, hence we spin it out as a company. We are looking for co-founders to join us on the journey to open up backbone of German Mittelstand to AI automation.

Waterlily | Multiple Roles, see below | Remote (with option to be hybrid in San Francisco, CA) | Full-time | www.waterlily.com
Waterlily uses advanced AI to tackle one of the biggest, unsolved challenges in retirement planning: long-term care (LTC). We have already closed enterprise deals with multiple Fortune 100 insurance carriers and distributors, and raised an oversubscribed $7m Seed round from backers such as Insight Partners, Nationwide, Edward Jones, Brewer Lane Ventures, and Genworth. Our mission is to help families proactively plan for LTC needs and costs, and reduce America's multi-trillion-dollar LTC crisis.
We have extremely high standards and expect our team to move quickly while maintaining top quality. Our interview process is rigorous, and most applicants will not pass. Those who do join a small, highly skilled team working directly with our founders (who started college at ages 11 and 14, attended UC Berkeley and MIT, and have built and sold successful startups backed by Founders Fund and Khosla Ventures before). We value rapid learning, candid feedback, and intense execution. We all invest more than 50 hours a week, sometimes up to 80, when needed to achieve top-tier outcomes. We want people who thrive in that environment, with the maturity to also pace themselves for sustainability.
Open Roles
Full-Stack Engineer

Narrative I/O | Senior/Staff Backend Engineer - Query Compiler | New York, NY | Full-time | REMOTE | $140k to $200k USD | https://narrative.io/
Narrative has been building a data collaboration platform designed for simplicity and ease of use since being founded in 2016.
Our primary strength is functioning as a data marketplace where we differentiate ourselves by:
- Automatically standardizing data, simplifying the user experience by eliminating the need to deal with n representations of the same underlying concept from different suppliers.
- Making platform data accessible through the Narrative Query Language (NQL) and easy-to-use UIs powered by NQL. This enables users to transform, deduplicate, and filter data instead of selecting from a set of provider-defined, pre-packaged datasets.
- Giving data providers the ability to define row-level access and pricing policies for their data.
We are a small, remote-first team looking for someone with experience working on query compilers or query execution systems in general. While the company's headquarters are in NYC, the development team currently includes engineers working from the US (California and New York), Canada (Alberta, British Columbia, and Québec), Poland, and Serbia.
In brief, the technologies we use are:
- Scala, Spark, Apache Iceberg, Apache Calcite, Cats, Cats-Effect, Http4s, FS2, Doobie, Deequ, Axolotl, BentoML, and HuggingFace Transformers. We love functional programming and make use of libraries like Cats, Cats-Effect, and FS2, but we keep a pragmatic stance on purity given our exposure to the Spark ecosystem.
- Our services are deployed on AWS and provisioned using Terraform. We leverage the usual suspects: Fargate, EMR, RDS, Lambda, etc. and we're starting to lean into Kubernetes. Being a small team, we think twice before rolling out custom infrastructure that we'll need to monitor and maintain.
- On the frontend, we use Typescript, VueJS, PrimeVue, Nuxt, and Vite.
