Superduper is looking for a DeFi Systems Engineer – Trading, Risk & Performance to shape an innovative user experience for decentralized finance. You will automate and abstract away the complexities of on-chain swaps and liquidity management without sacrificing performance or scalability.

What You'll Do

Build and optimize low-latency, high throughput APIs that abstract and simplify complex DeFi operations.
Build real‑time risk‑management modules for perpetuals, 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.

What We're Looking For

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.

Nice to Have

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.

Technical Stack

Languages: Go, C++, Solidity, Python
Blockchain Tools: Foundry, Hardhat
Profiling/Debugging: pprof, delve, gdb
Version Control & Infrastructure: Git, Docker, Kubernetes
Databases & Data Stores: MySQL, PostgreSQL, Redis, Kafka, Redpanda, ClickHouse, InfluxDB
API & Data: GraphQL, gRPC-Web
Cloud Platforms: AWS, GCP

Team & Environment

Collaborate with a high-performance team and cross-functional teams (design, marketing, product).

We are looking for a creative problem-solver who is eager to innovate and push boundaries in the DeFi space. You thrive in scrappy start-up environments, seeing ambiguity as an opportunity rather than an obstacle. You excel in collaboration, building trust and rapport with both technical and non-technical stakeholders, and are relentless in delivering high-quality products, even under pressure. You understand that speed and agility are key competitive advantages and drive urgency and efficiency without compromising quality. You are passionate about DeFi, with a commitment to continuous learning and staying at the forefront of this dynamic field.
