Volcore | Manchester, UK | ONSITE | Full-Time | Software Engineer

At Volcore, we model the electricity system to do proprietary trading that helps balance the grid and facilitate renewables integration. Our technical roles are a blend of Software Engineering and Data Science, wherein we solve problems end-to-end, from data ingestion and analysis to optimisation and deployment. Often these require novel solutions, drawing on original research and experimentation. We are a profitable and ambitious startup looking for Software Engineers who can both crack these kinds of problems and continually improve our shared libraries, tooling and workflows to ensure they are fast, accurate and a delight to work with.

Our team are close-knit, with minimal hierarchy. We work together in-office to whiteboard solutions together and everything we build is used by people sitting next to us.

Every team member owns important projects very early on, and if you can deliver value in a particular area, you’ll be recognised and rewarded for it, regardless of job title.

Our tech stack includes Python, backend Typescript, Postgres and, increasingly, Rust, although the latter is not a Day-1 requirement.

We review all applications personally. For more info, including salaries, requirements and application links:

We're Stored – a digital payments startup redefining how merchants sell and get paid. We recently closed an oversubscribed funding round, driven by several new partnership agreements with some of the world's largest payments businesses.

What we’re looking for:

-Strong experience with C# and back end systems.

-Deep understanding of Postgres, performance tuning, batching, and scaling.

-Proficiency in TypeScript, and capable of owning full features end-to-end.

-Comfortable handling front end logic (we use Svelte, but experience with any modern framework like React or Vue is fine). To be clear, you won't need to design/build UIs, but you should be able to work across the stack.

-Experience with Linux and networking, especially profiling/debugging in high-traffic production environments is desirable but not essential

-Fluent in written and verbal English

-Self-disciplined, motivated, and able to manage concurrent tasks

This is a fully remote role, but we’re based out of London, UK and so only considering candidates in GMT/BST ±3 time zones who are willing to work between the hours of 8am - 6pm GMT/BST.

PlantingSpace | Full-time | Remote (EU time zone) with quarterly meet-ups | https://planting.space

We’re building an AI system for analysts and scientists, based on a fundamentally new approach to reasoning and knowledge representation. Our approach differs from LLMs in that we compose algorithms symbolically to represent complex knowledge, and perform probabilistic computations. This enables the AI-driven application of statistical models to different problems, while providing the user with a verifiable reasoning path, and an assessment of the uncertainty in each answer. We are developing applications for analysis and research in domains such as Finance, Strategy Consulting, Engineering, Material Sciences, and more.

We’re currently hiring for: * Program Synthesis Engineers

* Senior DevOps Engineers

* Senior Product Manager

* Senior UX Designer

Drone startup | Product Engineer (Typescript) | 1 day/week in the office (London, UK) | Citizens of the UNITED KINGDOM only

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.
