You'd be working with other passionate product engineers who previously worked at Google, Amazon, Helsing, Darktrace and Improbable. You'd be working alongside me in building a modern, ground control station software for drones using web technology. For my project, we use React, Tailwind, drizzle-orm, SQLite, Postgres, maplibre, deck.gl, Node, Python, asyncio, FastAPI and more. We highly value passionate engineers with personal projects or technical hobbies, over leetcode engineers. Examples of things we're building: low latency data and video streaming services for collaboration, or intuitive/modern applications for planning and performing drone flights.
If interested, please reach out to my temporary disposal email: whole-heap-justly@duck.com
PS: I value collaboration: pair programming, discussing, teaching and learning from others. One positive signal is that I've gained 27k points on StackOverflow. Bonus points if you've demonstrated positive impact/glue in teams and organisations.
If you haven't heard of us before, we’re a quantitative trading firm that cares a lot about technology. This means building elegant solutions that scale well, never assuming that “best in market” is the same as “best possible,” and ensuring everybody has the resources needed to do their jobs well.
We're looking for folks in New York, London, Hong Kong, and Singapore for a variety of roles including, but not limited to:
- Data Engineers who can help us understand, clean, manage and share the data that guides our trading. At Jane Street, having a thorough and accurate understanding of data is at the core of everything we do – https://www.janestreet.com/join-jane-street/position/6558007...
- An Incident Responder with experience in digital forensics – https://www.janestreet.com/join-jane-street/position/7284341...

- Software Engineers who are intimately tied into every area of our business. We are big believers in functional programming, using OCaml, a statically-typed functional programming language, as our primary development language.

The research software engineer will work closely with our scientists to develop and deploy software and electronic hardware for experiment control, collection, storage, and data analysis. The experiments make use of complex control systems including video, audio, and fluidics, the data are processed by sophisticated algorithms including GPU-accelerated deep networks, and then transferred automatically to a central database. The successful candidate will interface with the core software development team based in Lisbon, as well as scientists in our member laboratories (located in London, Lisbon, Geneva, New York City, Long Island, Los Angeles, Princeton, and Seattle) to support experiments and ensure data is of high quality.
The ideal candidate would have experience with Linux, Python, Arduino systems, electronics, team programming, quality assurance, web design, and system administration. A flexible attitude, the ability to quickly adapt to new situations and learn new systems, and to work independently as part of a geographically distributed team, are essential. Experience with scientific research, networking, parallel computing, or relational databases would also be desirable. As this is a distributed collaboration, the candidate will have a home base at one of our member laboratories, but should be prepared to travel to the partner sites.

Our strategies run 24/7 without manual intervention powered by low-latency infrastructure and the latest machine learning techniques. We're a meritocratic and lean team of highly-motivated scientists and developers and as such value technical ability more than politics: what matters is how good your code is, not how well you sell yourself.

We issue Visa & Mastercard cards not backed by a bank. Instead we use stablecoins held in non custodial wallets.
This type of service is crucial for many people in places like Argentina, Colombia, Nigeria, Turkey, where inflation soars and sheltering in foreign currency is hard and often impossible.
Down the line, we want to take card payment settlement time down from days to minutes, which will remove a huge and expensive inefficiency in the card scheme.
We are headed by an ex-Mastercard, Google, Meta, and Binance team. Still very small: 5 people on the engineering team. We intend to continue growing small and senior. Our current team is skewed heavily towards senior with two former L7s from Meta/Google.
We have raised a seed early this year and are seconds from going live with first cards.
Looking for senior, passionate engineers in London. https://www.linkedin.com/jobs/view/4045016220
