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.

RESPONSIBILITIES

You will be responsible for building and maintaining the command-line tools, API servers, and Python SDKs that will be the primary interface for Autonity's end-users. 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.

Where to Advertise Blockchain Jobs in the UK (2026 Guide)

Advertising blockchain jobs in the UK requires a different approach to most technical hiring. The candidate pool is global in outlook but concentrated in specific communities — protocol engineers, smart contract developers, DeFi specialists and Web3 product leaders who move between roles through networks and community channels as much as traditional job boards. General job boards reach a broad audience but lack the specificity that blockchain professionals expect. Specialist platforms, crypto-native communities and targeted outreach each serve a different part of the market. This guide, published by BlockchainJobs.uk, covers where to advertise blockchain roles in the UK in 2026, how the main platforms compare, what employers should expect to pay, and what the data says about hiring across different role types.

New Blockchain Employers to Watch in 2026: UK and Global Companies Driving Web3 Careers

The blockchain and Web3 job market in the UK is evolving rapidly. After a period of volatility, the sector has entered a more mature phase—defined by institutional investment, real-world use cases, and infrastructure-led growth. For candidates exploring opportunities on BlockchainJobs.uk, the key shift is clear: the most exciting employers are no longer speculative crypto startups, but well-funded companies building the future of finance, payments, and digital assets. In this article, we explore the new blockchain employers to watch in 2026, focusing on companies that have recently raised funding, secured major contracts, or expanded into the UK market.

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.
