ABOUT CLEARMATICS

Clearmatics is a blockchain protocol engineering company that builds decentralised financial market infrastructures that are more open, efficient, and resilient than those serving legacy market structures of today.

We have a bold vision for this new market infrastructure - enabling market participants to solve currently unaddressed problems of the real economy, including "missing markets" problems. We aim to achieve our vision through technologies that allow peer-to-peer trading and settlement within new markets, and with digital assets whose values track real-world risk factors that currently have no suitable expression in legacy markets.

No matter the nature of a risk factor, whether macro-economic or relating to real-world metrics such as climate data, our mission is to make important risk factors tradable; by anyone, anywhere, without reliance on financial intermediaries. We are building this new infrastructure in collaboration with incredible trading and blockchain communities.

Clearmatics was founded in 2015, and we have ever since been committed advocates of Open Source development, and active participants in the blockchain and cryptography research communities. We've also been an active participant and supporter of decentralized infrastructure initiatives.

We're growing our team and are looking for a Senior Python Software Engineer to join us and become part of our journey.

Our stack is Ethereum-like, so familiarity with – and passion for – the space is key.

Some of the areas we tackle include blockchain infrastructure optimized for financial use-cases, protocols for specific applications (such as smart contract-based derivatives, synthetic assets, cryptocurrency stabilization, …), scalability and privacy through cryptography (zkSNARKs, multiparty computation, private transactions/assets).

Currently the Clearmatics team is heavily involved as the Launch Partner for the Autonity Project. Autonity is an EVM based public blockchain for decentralised derivatives clearing. You can learn more about the Autonity project and its ongoing testnet games through the links below.

The apps, libraries, frameworks, and services that you develop will enable the creation of decentralised risk markets and a new market structure for DeFi on the Autonity blockchain.

How Many Blockchain Tools Do You Need to Know to Get a Blockchain Job?

If you are navigating the blockchain job market, it can feel like you need to master an entire tech stack before you’re even ready to apply. One job advert mentions Solidity, another talks about Hyperledger Fabric, another lists MetaMask, Hardhat, Git, Truffle, and Web3.js — and that’s before you scroll past three LinkedIn posts about “top blockchain skills for 2026.” It’s no wonder job seekers feel overwhelmed. But here’s the honest truth that many hiring managers quietly agree on: 👉 You don’t need to know every blockchain tool to get hired. 👉 You need to know the right ones for the role you’re targeting — and how to use them to solve real problems. Tools matter, but context and capability matter more. This guide breaks down exactly how many blockchain tools you need to learn, which ones matter for specific roles, and how to position what you know so hiring managers take notice.

What Hiring Managers Look for First in Blockchain Job Applications (UK Guide)

Hiring managers in blockchain tech do not start by reading every line of your CV. They scan for credibility, clarity and relevance, and they make an early judgement about whether you can solve real problems in a cutting-edge, evolving landscape. In blockchain and distributed ledger roles—whether in core protocol teams, smart contract development, Web3 infrastructure, compliance/security, or product-focused positions—the strongest applications make the right signals obvious in the first 10–20 seconds. This in-depth guide explains exactly what hiring managers in UK blockchain jobs look for first, how they assess CVs, cover letters and portfolios, and why strong candidates sometimes get overlooked. Use it as a practical checklist before you apply for roles on www.blockchainjobs.uk

The Skills Gap in Blockchain Jobs: What Universities Aren’t Teaching

Blockchain technology has moved far beyond cryptocurrency headlines. Across finance, supply chains, cybersecurity, gaming, digital identity, healthcare, and public infrastructure, distributed ledger technology is being explored, tested and deployed at scale. Yet despite growing adoption, blockchain employers across the UK consistently report the same problem: a severe shortage of job-ready talent. Graduates emerge with theoretical knowledge, computer science fundamentals, or an interest in decentralisation—but struggle to meet the practical demands of blockchain roles. Vacancies remain open. Startups compete aggressively for experienced hires. Employers spend months searching for candidates who can contribute from day one. The issue is not intelligence. It is not motivation. It is not even demand. The problem is a widening skills gap between blockchain education and real blockchain jobs. This article explores that gap in depth: what universities teach well, what they routinely miss, why the gap exists, what UK employers actually want, and how jobseekers can bridge the divide to build sustainable careers in blockchain.
