The Role

As a DeFi Systems Engineer, you will play a key role in shaping and building an innovative user experience for the future of decentralised finance. We are looking for a skilled developer who is passionate about automating and abstracting away the complexities of on‑chain swaps and liquidity management without sacrificing performance or scalability to provide a trading experience that can only be described as magic by end users. This role offers a unique opportunity to collaborate with a high‑performance team in developing a cutting‑edge product that will redefine the DeFi ecosystem and advance our mission to transform the industry.

• 
  
• Build and optimize low‑latency, high throughput APIs that abstract and simplify complex DeFi operations.
  
• Build real‑time risk‑management modules for perpetuals (perps), options, and binary products, covering margin calculations, collateral monitoring, and automated liquidations.
  
• Work closely with frontend developers to ensure seamless interaction between the frontend and APIs or blockchain nodes for real‑time data display.
  
• Ensure security best practices are followed, particularly concerning user data and blockchain interactions.
  
• Collaborate with cross‑functional teams (design, marketing, product) to deliver new features and improvements according to the product roadmap.
  
• Maintain code excellence: author clean, efficient, and maintainable code; implement comprehensive testing and debugging; lead code reviews, share best practices, and mentor teammates.
  

• 
  
• Must have 5+ years of experience in a similar role and level.
  
• Proven track record building high performance, production‑grade, low‑latency systems or microservices in Go, C++, or equivalent systems‑level language, with deep expertise in lock‑free data structures and cache‑aware memory layouts.
  
• Familiarity with key DeFi protocols and aggregators (Jupiter, Uniswap, Jito, Flashbots).
  
• Deep understanding of derivatives pricing and risk (Black‑Scholes, greeks, margin, hedging).
  
• Strong understanding of crypto markets, order‑book mechanics, market‑data feed architectures, and risk‑control frameworks.
  
• Experience developing EVM Smart Contracts using Solidity and popular toolchains (Foundry or Hardhat).
  
• Experience in profiling and benchmarking with tools such as pprof, delve, and gdb and meeting end‑to‑end performance SLAs.
  
• Experience with version control systems (e.g., Git) in a production setting.
  
• Experience with Docker and Kubernetes (or equivalent) for packaging and running microservices in a production environment.
  
• Experience designing and managing relational databases (MySQL, PostgreSQL) and in‑memory data stores (Redis), including schema design, indexing, and caching strategies for low‑latency services.
  
• Experience with market‑data infrastructure and back‑testing frameworks: hands‑on building and operating real‑time data pipelines (Kafka/Redpanda, ClickHouse/InfluxDB) and authoring production‑grade back‑testing and simulation systems in Python or Go.
  

• 
  
• A creative problem‑solver eager to innovate and push boundaries in the DeFi space.
  
• Possesses a deep understanding of web technologies and a strong grasp of risk management and trading system architectures.
  
• Thrives in scrappy start‑up environments, seeing ambiguity as an opportunity rather than an obstacle.
  
• Comfortable taking ownership of complex problems and transforming them into user‑friendly solutions.
  
• Excels in collaboration, building trust and rapport with both technical and non‑technical stakeholders.
  
• Adept at communicating complex concepts clearly and concisely.
  
• Relentless in delivering high‑quality products, even under pressure.

• Passionate about DeFi, with a commitment to continuous learning and staying at the forefront of this dynamic field.
  

• 
  
• Experience building order‑book DEXes (e.g., Serum‑style).
  
• Experience integrating natively with DeFi protocols and smart contracts (e.g., Uniswap Router, pump.fun liquidity pools, multicall, etc.).
  
• Experience developing and deploying Solana Smart Contracts with Anchor.
  
• Experience with GraphQL schema design and sub‑second subscription handling and/or gRPC‑Web for low‑latency data flows.
  
• Experience building production‑grade back‑testing and simulation frameworks in Python or Go.
  
• Familiarity with dark‑pool trading architectures and zero‑knowledge proof systems (e.g., zkSNARKs, zk‑STARKs) and how they integrate into DeFi protocols.
  
• Familiarity with cloud platforms (AWS, GCP) and infrastructure‑as‑code.
