About Raven Black
What turns a minor skirmish into a major war? How does a natural disaster become a humanitarian crisis? Often, its poor decision-making caused by incomplete or inaccurate information that causes miscalculations, missed opportunities, and accidental escalations. That lack of knowledge and the uncertainty it causes is called "the fog of war."
Raven Black's command and control software platform does precisely that by combining scalable data infrastructure, machine learning, and visualization tools. Its purpose is to lift the fog. Raven Black has raised $4.5M from top tier VCs, including Accel, and has generated over $3.9M in revenue.
What You'll Do
Our platform ties together dozens of data sources, any one of which could be the critical piece of the puzzle a decision-maker needs. Your job will be to thread new sources through our platform, from ingestion through parsing, ETL, ML/AI models, and visualization. In the process, you'll learn everything about how the system works and contribute to our core infrastructure development. Each time you succeed, the fog of uncertainty will retreat that much further.
You may be a great fit if you...
smlXL is a 'stealth' start-up building an Information retrieval service with Consumer and Enterprise applications. Our first focus is providing a far richer understanding of the semantics of blockchain activity, making data and information accessible and useful to all.
We aren't ready to talk broadly about what we are working on, but we might be a good place for you if:
You are highly technical; you care about your craft; you are constantly learning; used to working on baremetal servers and running your own stack, you are fascinated by Information Systems, Semiotics, and Blockchain data; you get excited by turning black boxes transparent; and you love working on things that add a ton of value to consumers and prosumers alike; or you are into the EVM, decompilers, databases, and distributed systems.

The API has its key part on it but the load is also on a multitude of other services.
You will work closely with our technical teams to learn about the possible technical bottle-necks. We have implemented different technologies such as Go (go-kit toolkit, gRPC…), Kubernetes, AWS, PostgreSQL and many others. Your role would be to lead us to new technologies that our product can benefit from.

You will join a talented team of 10 engineers, Data Scientists and DevOps, that are tech-passionate, working closely with most of them. Our main goal is to ensure that we can contribute to your personal growth as an engineer.
Payments are often compared to a black-box. Merchants around the world have issues understanding how their performance is and what optimization can be done. Our team is focused on building the best payment performance tool there is. It allows merchants to better understand their online processes as well as offline payments.
We offer 2 products to our merchants:The first, named Telescope, allows us to analyse, understand and make recommendations to a merchant. It does not require any technical integration from them and works mainly through webhooks, pulling data from APIs or parsing exported files.
If you don't meet all the requirements but think you might still be right for the role, please apply anyway. We're always keen to speak to people who connect with our mission and values.

We’re changing the way people think about transportation. Not that long ago we were just an app to request premium black cars in a few metropolitan areas. Now we’re a part of the logistical fabric of more than 600 cities around the world. Whether it’s a ride, a sandwich, or a package, we use technology to give people what they want, when they want it.
