Backend Engineer (Rust / Python – DeFi Trading)

London or Remote (Europe)


A DeFi-native trading platform is building high-performance, user-focused trading tools and is looking for a backend engineer to help shape the core platform. The team strongly believes DeFi is the future of finance and is focused on making fast, reliable on-chain trading accessible to everyone.


You’ll work hands-on with Rust and Python, build public APIs, and integrate directly with smart contracts and trading logic. This is a highly product-driven role with real ownership and daily production impact.


What they’re looking for

  • Strong experience with Rust and/or Python
  • Hands-on experience working with EVM smart contracts (application-level Solidity, not just theory)
  • 3–4+ years in crypto / DeFi–native roles
  • Solid understanding of decentralised exchanges and the current DeFi landscape
  • A grasp of trading concepts, or a strong desire to move deeper into trading systems
  • Experience running production systems in the cloud


Nice to have

  • Writing and deploying smart contracts
  • Experience diagnosing performance or latency issues
  • On-chain trading experience or strategy work
  • Exposure to other ecosystems such as Solana, Sui, or Cosmos


A strong opportunity for someone who is deep in crypto, cares about the product as much as the code, and wants to help build the next generation of DeFi trading tools.

Maths for Blockchain Jobs: The Only Topics You Actually Need (& How to Learn Them)

If you are targeting blockchain jobs in the UK whether that is smart contract development, protocol engineering, security auditing, data engineering, blockchain infrastructure or Web3 product roles the maths can feel like a hidden barrier. Job adverts often ask for “strong fundamentals” or “cryptography knowledge” without saying what you actually need day to day. The good news is you do not need a maths degree worth of theory to start applying. For most roles you can get job-ready by mastering a small set of practical topics that show up again & again: Modular arithmetic & number theory basics (the backbone of public key cryptography) Probability & simple statistics (security assumptions, block times, risk reasoning) Discrete maths & data structures (Merkle trees, hashing, complexity, graphs) Cryptographic primitives at a “working engineer” level (hashing, signatures, commitments) Basic optimisation thinking (gas cost, performance, trade offs) This guide is written for UK job seekers who want a clear scope, a 6-week plan & portfolio projects that prove you can translate the maths into working code.

Neurodiversity in Blockchain Careers: Turning Different Thinking into a Superpower

Blockchain is still a young, fast-changing field. It attracts people who challenge the status quo, question systems & build new ways for value, trust & identity to move around the world. That makes it a natural space for many neurodivergent people. If you live with ADHD, autism or dyslexia, you may have been told your brain is “too distracted”, “too literal” or “too chaotic” for a technical career. In reality, the same traits that can make traditional workplaces hard often line up perfectly with blockchain work – from deep focus on protocol details to creative problem-solving in DeFi, DAOs & web3 products. This guide is written for blockchain job seekers in the UK. We will cover: What neurodiversity means in a blockchain context How ADHD, autism & dyslexia strengths map to specific blockchain roles Practical workplace adjustments you can ask for under UK law How to talk about your neurodivergence during applications & interviews By the end, you will have a clearer sense of where you might thrive in blockchain – & how to turn different thinking into a strategic career advantage.

Blockchain Hiring Trends 2026: What to Watch Out For (For Job Seekers & Recruiters)

As we move into 2026, the blockchain jobs market in the UK is at an interesting crossroads. The speculative crypto boom years have cooled, some Web3 companies have downsized or disappeared, & yet demand for serious blockchain talent remains strong – especially where real-world utility, regulation & enterprise adoption meet. Tokenisation of real-world assets, regulated digital securities, central bank digital currency (CBDC) pilots, on-chain compliance tools & enterprise blockchain platforms are all moving from experiment to implementation. At the same time, hiring is more selective, funding is more cautious, & the bar for blockchain roles has risen. Whether you are a blockchain job seeker planning your next move, or a recruiter trying to build credible Web3 or enterprise blockchain teams, understanding the key blockchain hiring trends for 2026 will help you stay ahead.
