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. You will be joining a stealth-mode initiative supported by a well-funded company, allowing you to innovate in a fast-paced, dynamic environment with the resources and support needed to push the boundaries of technology. Your work will directly contribute to creating a product that will have a profound impact on the world of DeFi, underpinned by the financial strength and strategic direction of our organisation

Key Responsibilities

• 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; and lead code reviews, share best practices, and mentor teammates.

Knowledge & Experience

• 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.

Ideal Candidate Profile

• A creative problem-solver who is 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.

• Understands that speed and agility are key competitive advantages and drives urgency and efficiency without compromising quality.

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

Nice to Haves

• 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 Achor

• 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
