Supercede builds industry-leading risk placement and analytics software for the reinsurance industry. We favour asynchronous communication, and try to hire "managers of one". We don't do daily stand-ups. We don't count your hours. We don't work weekends. We support each other in working and learning. We prefer responsibility and autonomy, and eschew micromanagement.
## About the tech
Our core product is a monolithic web application written in ~180,000 lines of Haskell, predominantly with the Yesod framework.
In short: Haskell, Yesod, Nix, PostgreSQL, Redis, Hspec/QuickCheck/Hedgehog, Persistent/Esqueleto, HTML/CSS/JavaScript.
## About you
For this particular role, we are looking for someone based in London, who can come and work with us regularly in our lovely office at the top end of London Bridge (hybrid working is supported).
Technical proficiency aside, we need you to be self-motivated and be able to manage your own time. We get stuff done at a sustainable pace.
As most communication is asynchronous, you'll need to be an excellent communicator. This mostly means you need to think and write clearly, whether that's in code, or in English. We expect you to describe your approach to a given problem in writing before diving into an implementation, and you'll need to collaborate with colleagues on your design.
You'll need to be a good engineer. We aren't looking for cathedral architects or type-system astronauts. We need small, simple, robust design. It's always better if you can make our project smaller, faster to compile, and easier to maintain so more junior colleagues remain effective.
On this team we are kind. We're kind to each other socially, and we're kind when reviewing and collaborating on work. We're diverse and multicultural, and respectful of each other's background. You'll need to be kind.
If you're interested in working with us, please write to me at jezen@supercede.com.

We also believe in the value of open source software, using it in our daily work and releasing hundreds of thousands of lines of our own code as open source -- https://www.janestreet.com/join-jane-street/position/4274288...

To the software engineer: offering a chance to write code as either our third or fourth engineer (django/postgres/python), learn to drive a forklift (Hyster J2.0UTT) and wire up label printers (brother-ql 1100c + a new zebra one which I bricked using Chat GPT sending commands directly through).
Experience as a forklift driver or as a software engineer not essential.
To the sales/operations hire: help us open new marketplaces; get stock to whomever you sold it to; also learn to drive a forklift; dealing with compliance, licenses and related issues; map navigation skills and aviation a plus (the last one was a joke, but if you can drive that might be handy).

We all have a sense that AI has the potential to change the world for the better; to push humanity forward. To fulfil its potential, artificial intelligence must run at the edge wherever it is needed, and not be dependent on cloud connectivity. To meet society's needs, AI has to be explainable, it has to be fast, and it has to be economically and energy efficient. Literal Labs is working to make that happen.
At Literal Labs, we are pioneers in the AI sector, dedicated to transforming the landscape of technology through innovative AI solutions. With a foundation deeply rooted in engineering and scientific excellence, we strive to create impactful tools and applications that redefine the interaction between humans and technology. Our commitment to high-quality work, employee development, and a collaborative culture makes us a beacon for those who aspire to shape the future of AI.
As the Product Engineering Pod Lead, you will be at the forefront of architecting and developing web applications and cloud solutions that integrate our groundbreaking Tsetlin Machine technology.
This role is pivotal in turning sophisticated AI capabilities into accessible, user-friendly products that will revolutionise how our customers interact with AI. You will collaborate directly with the CTO and other pod leaders to ensure our technological solutions are robust, scalable, and aligned with Literal Labs’ strategic goals.
Please note: We are looking for a generalist in this role, an experienced set of hands that has overseen the complete lifecycle of web applications in previous experiences, and has solved the plethora of issues that arise along the way.
What We Offer; a place for ambitious people, a dynamic role in a rapidly growing company at the cutting edge of AI technology; a company for personal development: Opportunities for professional growth through our culture, conferences, training, and courses, with resources available from our partnership with Newcastle University; no politics, no red-tape, but instead an exciting space: A collaborative, innovative, and fun work environment (because it should be) where your voice is valued, we pull together, and your contributions define the future of the company; benefits include early stage equity, pension scheme and an unlimited holiday scheme.
Please reach out to me (leon at literal-labs.ai) with the subject "HN" for more information, or see our LinkedIn JD: https://www.linkedin.com/jobs/view/3942949387
Thanks!
