Senior Software Engineer

At Magic Eden, we’re breaking down barriers to make Web3 what it should be — intuitive, accessible and of course, magical. As the #1 Bitcoin dApp and the #1 NFT marketplace, we’re leading the charge to redefine the onchain experience. Backed by top-tier investors like Sequoia, Paradigm, Electric Capital and Lightspeed Ventures, we’re building a future where trading is seamless, tokenomics are meaningful and Magic Eden fulfills its mission of making digital ownership universal. Join our global team of passionate, scrappy and wildly talented people to help shape the next era of Web3 with us. This platform will sit at the intersection of sports, trading, and Web3. That means high-volume data streams, real-time odds, market‑making mechanics, and financial‑grade reliability — all built from scratch. We’re still small, moving fast, and setting the technical foundations for scale. The work is complex, high‑impact, and very visible. The challenge This isn’t a maintenance role — it’s a zero‑to‑one system build. You’ll design distributed, event‑driven systems, optimise for speed and scalability, and make architectural calls that shape how millions of bets move across the network. We’re looking for someone who can balance pace with rigour: ship fast, but build for the long term. You should be comfortable leading projects end‑to‑end — from initial design through to production support — and mentoring others along the way. What you’ll do Lead the design and development of backend services using Node.js, TypeScript, and AWS . Own your domain end‑to‑end: architecture, build, deploy, and monitor in production. Build and optimise data pipelines and event‑driven systems (Kafka, Kinesis, or equivalent). Build relationships across disciplines like Infrastructure to remove blockers and get things done. Contribute to technical direction, design reviews, and cross‑team engineering decisions. What we’re looking for 6+ years’ experience building and scaling production systems. Proven experience delivering high‑throughput, low‑latency services (fintech, betting, gaming, trading, or similar). Strong foundation in distributed systems, cloud infrastructure, and data streaming. Comfortable leading small teams or large projects, designing, developing, delivering, and supporting systems at scale. Either deep industry experience in betting/sports , or a strong domain specialisation (e.g. streaming, real‑time data, distributed systems). We can trade one for the other if you truly excel. Resourceful, respectfully opinionated , generous with knowledge. You care about quality, impact, and the people who ship alongside you. We value extreme accountability , collaboration , and clarity of ownership . Engineers here are expected to be self‑directed — to identify what needs to be built and take it from concept to code. Bring your ideas, build prototypes, show them off. Why join now Join from day zero, when your code shapes the platform. Build alongside founders who scaled Magic Eden from idea to unicorn in nine months. Work directly with Sid Zhang (CTO/Co‑Founder) and a senior engineering team with deep experience in large‑scale, real‑time systems. We’re Melbourne‑based, office‑first (four days onsite while we build momentum). Competitive compensation + equity at a company that’s proved it can scale fast. This is a build‑the‑plane‑while‑flying‑it kind of role. If that sounds like your kind of fun, let’s talk. #J-18808-Ljbffr
