About Carebit
[Carebit](http://www.carebit.co) is a young, design-led healthcare technology company helping over 1500 private doctors across the UK run their practices more effectively and efficiently with our web and mobile platform, along with hundreds of thousands of their patients. For too long, medical software has been clunky, user-hostile and complicated, and we are changing that. Several customers have independently described us as ’the Apple of practice management software’.
We are a bootstrapped, profitable and remote-first company of 30 people with 6 full stack engineers including the company’s founder, Dominic. Having been remote from day 1, we fully believe in its benefits. We do have a lovely office in London by the river for in-person collaboration when required, but this is not mandatory as we know some like in-person working and some prefer fully remote!
About you
We’re looking for a Senior Support Engineer to work with our Support and Data Migration teams for day to day work troubleshooting and resolving technical customer issues. We’re specifically after someone who is curious, experienced and enjoys investigating and solving technical issues that vary from fixing simple bugs to small tweaks to existing features (e.g. adding a new column to a CSV export) to writing Ruby scripts to execute changes after a data migration to Carebit.
You’ll likely have a strong software development background already. This is a hands-on role where you’ll be regularly shipping fixes and improvements to the core Carebit platform as well.
- Strong experience with Ruby on Rails and React, especially design patterns (we use Rails 7 and Ruby 3.4 with Postgres 17, deployed to AWS ECS) - Bonus points for Linux/sysadmin and Postgres knowledge - Fluent in written and verbal English and an excellent, timely communicator - especially with customers - Self-disciplined, autonomous, motivated, and able to manage concurrent tasks
This is a fully remote role but we operate on London, UK time and so are only considering candidates in GMT/BST ±3 time zones who are willing to work to UK hours (typically 9am-5.30pm)
Please email CVs to hiring[[at]]carebit dot co if you’re interested in learning more!
- Deploying clusters of 1,000+ GPUs and operating them with and for customers.
- Validating correctness and performance of underlying compute, storage, and networking infrastructure, and working with providers to optimize these subsystems.
- Migrating petabytes of data from public cloud platforms to local storage, as quickly and cost effectively as possible.
- Debugging issues anywhere in the stack, from “this server’s fan is blocked by a plastic bag” to “optimizing S3 dataloaders from buckets in different regions”.
- Building internal tooling to decrease deployment time and increase cluster reliability, including automation where the customer benefits clearly outweigh the implementation overhead.
We don't require prior experience with GPUs or AI/ML; we require a willingness to learn quickly, work hard, and obsess about customer success.

At Edra we built a new, proprietary method of learning that allows LLMs to understand and automate business processes.
Founded by Eugen and Yannis, former co-heads of Forward Deployed AI Engineering at Palantir. We believe that as we get closer to AGI, the ability to teach models what you want them to do will become the key bottleneck in deployment to enterprises, and traditional training approaches won’t cut it. We named the company Edra for “the seat of the teacher”.
Edra AI is a novel learning system, deployed with several customers and are looking to scale up. Backed by top-tier investors from the Palantir ecosystem with offices in New York and London.
Still in stealth, reach out to hiring@edra.ai for more.
We’re hiring:
- AI Engineers (New York/London): You’ll work on building the future of AI whitebox learning
- Full-Stack Product Engineers (London): Help us deliver a fast and powerful user-facing platform. Stack includes Next.js, TypeScript, FastAPI, Python, and Postgres.
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-june25@mail.orth.uk with your CV and some personalised information about why you'd be the right fit.
