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.

Would you like to help tackle one of the most important sectors for the global economy - maritime shipping? We're hiring for multiple roles: software engineers, data analysts, UI/UX designers, implementation managers.
Nearly every person is affected by stuff shipping on the seas - whether its energy, ore, or wind turbines, but the industry itself is antiquated and archaic, and hampered by paperwork and bureaucracy. Our customers are crying out for better solutions. We're looking for people to help us build those solutions.
If you're the sort of person who is: - intellectually curious about new industries - wanting talking to and getting close to end users - keen to use LLMs and other AI tools

For our SWE roles we have budgeted ~ 90k USD.
Our tech stack for new projects is largely typescript/vue/mysql (we have several fans of fp-ts and EffectT with us and are investing in using more functional programming). But like the industry at large we also have significant legacy code in javascript. If you're the sort of person who likes refactoring complex projects to make them more workable, then we also want to hear from you.

For our Data Analyst or Implementation Manager roles:
You'll be helping our customers in maritime shipping get the most from our software. Initially, a lot of that work will be in helping our customers get their data in and out of it. Lot's of MySQL, Metabase, AWS Glue, DBT, or other ETL pipelines.
--
For our UI/UX designer roles we have budgeted ~ 40k USD.
You'll be helping us on three different axes: (1) designing the user interface for new features, (2) fleshing out the user journeys and mockups for our roadmap, and (3) helping us craft a consistent and learnable user experience across all our software.

We hire remotely and globally with offices in Houston, London, Singapore, and Joinville (Brasil). You should be fluent in English. The current team is >20 people. You should be in a timezone within 3 hours of one of those offices.

We are a small international team, with members in Cupertino, CA, and London, UK. We are looking for senior software engineers to join our team. The role involves a large amount of individual responsibility and influence over the direction of a core service.
We believe in small agile teams and their ability to deliver high-quality, high-impact software. We share code ownership and knowledge through the Agile technique of pair-programming. Our codebase is written entirely in modern Rust using the latest technologies and coding practices.
The core work includes:
* Designing, implementing, and supporting highly scalable applications and web services
* Working in Rust (e.g., asynchronous (async/await), sharing models (Sync/Send), etc.)
* Concurrent programming (e.g., locking, memory synchronization, atomic operations, etc.)
* Distributed system concepts (e.g., distributed consensus, replication, failure detection, etc.)
This role requires working with pair programming (remote and if possible in-person) and may require occasional international travel/transatlantic travel.
You can reach us by emailing your resume to mansur.ashraf@<company_name>.com

You'd be working with engineers who previously worked at Google, Amazon, Helsing, Darktrace and an F1 team. We build drones (software and hardware)
We're looking for engineers that straddle real world problems, and use technology as a solution. We prefer personal projects or relevant hobbies, not hard leetcode questions. We value collaboration: pair programming, discussing, teaching and learning from others. We're looking for mission-driven engineers. People who see problems in the world and want to help solve them.
You'd be working with me to build the most intuitive, performant, and modern mission planning and flight monitoring software for drones, and related applications (tools for drone design and manufacturing). For my project, we use React, Tailwind, Node, drizzle-orm, Postgres, SQLite, deck.gl, Python, FastAPI, asyncio, and more. You're allowed (and compensated) to use AI services.
Because we are a small team, you will be noticed and rewarded for performance.
*Please don’t apply if any of these resonate:*
• You prefer narrow ownership—“I only touch the backend or the code I've written”.
• You think it's more about "who you know, not what you know".
• You haven’t actively learned a new tool or hobby in the last year.
If interested, email my temporary email: hn-may25@mail.orth.uk with your CV and some personalised information about why you'd be the right fit.

Engineering at Ameba is a rare opportunity to build cutting-edge software in a traditional industry, while being generously rewarded for your contributions.
If you’ve never considered working in supply chains before, everything around you, including the device you're reading this on, has a story of how it got there. Raw material to finished product, that story is the supply chain. If the unseen machinery of the world sparks something in you, we'd love to talk!
We're a startup made up of experienced entrepreneurs (who have previously raised $160m+) and builders (ex-Meta, Palantir, Microsoft, Quant Devs, UnlikelyAI). We have big ambitions and are backed by some of the most successful investors in Europe. Since launching just over a year ago, we’ve raised more than $9M and are already working with some of Europe's biggest brands — and things are only just getting started.

We’re ko-br – a London-based AI robotics startup on a mission to end the "3AM cobot meltdown" in warehouses. Our robots handle real-world chaos (grip slips, conveyor jams, dust storms) through:
* No-code AI that plugs into ABB/KUKA/UR arms
* Self-recovery protocols proven to reduce emergency calls by 85%
* Human-taught systems that turn warehouse teams into robot mentors
Why This Matters
Industrial robots keep failing when faced with mixed SKUs or shifted pallets. We’re fighting this $35B conformity crisis (see manifesto) by building robots that adapt to humans – not the other way around.
We Need You If You’ve…
* Scaled commercial ops in industrial tech/robotics/AI
* Closed 6-7 figure deals within the logistics space
* Built partner ecosystems around OEMs like ABB/KUKA
* Crave building vs. babysitting (this is hands-on founding role)
Founding Team
* Founder: Ex-Amazon/Meta ML engineer, expertise in ML infrastructure, computer vision, distributed systems, and building Internet-scale ML pipelines.
* Team: 40+ years combined expertise in VR, ML, robotics, MLOps, data annotation and cybersecurity
Apply

Ever wanted to work in the UK rail-ticketing retail space?
Raileasy, who own and operate the TrainSplit brand, are hiring for a junior backend software engineer.
Our API powers some of the most established and recognisable brands in the independent rail retail space (particularly where split-ticketing is involved) such as TrainSplit, Realtime Tickets from Realtime Trains, Split My Fare, Railboard and others. We provide both B2C and B2B ticket booking services. We are a remote-first organisation; we have engineers in a variety of locations across the UK, but we make good use of pair programming, video conferencing, asynchronous communication and in-person meet-ups at mutually accessible locations to collaborate.
We’re looking for someone UK-based who will be able to work on our .NET-based services, primarily in C# – but we have a variety of smaller services written in languages like Golang and Rust too. This role would be ideal for someone who has recently graduated from e.g. a CS course, or has taught themselves how to program and now has a decent grasp on the fundamentals. Any internships, placement years and/or open source contributions/repositories (even if it's just a few Advent of Code days) you could show us would reflect well on your application.
An interest in public transport/rail would be a plus, but is by no means a requirement.
For more information about the role and our API’s architecture, please see https://raileasy.co.uk/careers and the full specification at https://raileasy.co.uk/backend-engineer
For questions send us an email to careers AT trainsplit.com. To apply, email a copy of your CV to the same email address.
No agencies, please and unfortunately, we are unable to accept applications from candidates who do not have the right to work in the UK.
