Role Intro
Ethereal is DeFi’s next major trading protocol and the first built on Ethena. Recently launching Testnet, we’re at $700M+ TVL on track to become a top 10 ecosystem. This is a rare opportunity to join a world class DeFi team.
We’re building a Perps DEX, which will handle over 1 million orders per second delivering CEX level performance, with on-chain security.
You’ll be part of an engineering-first team solving deep, complex problems that haven’t been tackled before. If you thrive in an environment about optimisation, distributed systems, and real-time performance at scale, this is your kind of challenge.
This is a remote team who work within AEST, strong preference for AU/NZ location, but all applications must be from timezones within GMT +7 and GMT+13.
About the Role
We’re hiring a Senior Backend Engineer to help design and optimise the core infrastructure across both an on/off chain EVM/Typescript architecture. You’ll be working on high-throughput systems that redefine execution speed and efficiency in DeFi.
What You’ll Be Doing
- Designing and implementing scalable, distributed backend systems to handle millions of orders per second.
- Optimising for latency and performance
- Working with event-driven architectures, real-time data pipelines, and high-throughput APIs.
- Collaborating with front end and protocol engineers to build an entirely new class of DeFi trading infrastructure.
- Ensuring fault tolerance, efficiency, and security across the platform.
What We’re Looking For
Essential Skills:
- Strong experience in backend development using Node.js & TypeScript building applications that have proven to scale
- Deep understanding of and experience with distributed systems - scalability, high availability, and performance tuning.
- Strong experience with CI/CD, AWS.
- Experience building or contributing to production DeFi or web3 projects.
Highly desirable:
- Prior work with real-time trading systems or large-scale on-chain applications
- Solidity/smart contract knowledge is not essential but a bonus.
Why Join Us?
- Fully remote (AEST ± 3 hours)
- Get paid on-chain (USD stables)
- Work alongside world-class engineers building core DeFi infrastructure
- Get early ownership in a protocol with $700M+ TVL and serious momentum
- Solve complex, technical problems with real user impact
- No politics - just sharp, curious engineers delivering fast

Fountain
New York(NY)
What We’re Building
Ares is the newest product under Fountain Platform, focused on building high-performance social trading platform for decentralized markets.
We believe trading has evolved — it’s no longer solitary. It’s cultural. It’s real-time. It’s driven by memes, narratives, and reflexive attention loops. Yet most platforms are stuck in static tools built for yesterday’s market structure.
Ares is built for what trading has become — and where it’s going. We fuse speed, signal, social mechanics, and cultural context into a unified trading experience designed for today’s markets — and tomorrow’s meta. At the core is a real-time intelligence layer that aggregates onchain and offchain data, surfacing the pulse of the market as it emerges. But information alone isn’t power — influence is. Ares turns trading into a collaborative, reputation-driven game where every trade is a signal, and every user is a node of intelligence.
We’re not building a better terminal. We’re building the next dominant trading platform — one where culture leads, conviction is rewarded, and traders move markets together.
We’re backed by top VCs and Alliance (tier 1 crypto incubator). This is your opportunity to help define what the future of trading looks like — from the ground up. This isn’t a typical job — and we’re not looking for typical people. We want resourceful, hungry, top 1% builders who move fast and think like founders.
About the Role:
We’re looking for a product-driven senior or staff-level engineer. Our engineering team tackles complex challenges at the core of our trading infrastructure and user experience. At Ares, engineering defines the culture, pace, and quality of everything we build — pushing the limits of what’s possible in crypto-native systems.
What You’ll Do
- Work directly with the CEO and have transparency into other aspects of the company
- Architect important systems and anticipate strategic and scaling-related challenges via thoughtful long-term planning
- Design and implement core infrastructure across the full stack — from high-performance frontends in Next.js + Tailwind to backend systems in NestJS, PostgreSQL, Redis, and Solana RPCs
- Work on transactional engines that optimize for execution speed, accuracy, and UX under volatile, memecoin-driven conditions
- Drive the architecture of our real-time trading intelligence layer, fusing onchain and offchain signals into actionable interfaces
- Build integrations with external services (Telegram, bots, alerting engines) to power novel product experiences
- Ship fast and often — we deploy product daily and treat working code as the ultimate source of truth
- Collaborate directly with founders and a small team of senior engineers in a high-bandwidth, fast feedback loop
- Engage with early users — from CT influencers to alpha groups — and shape features around real workflows
- Take ownership over what you build, with freedom to make autonomous decisions and move without bureaucracy
Our Tech Stack
Tech Stack: Nest.js, Solana, Redis, Postgresql, Typescript, Nodejs, Materialize, gRPC, Drizzle, Websocket, Google Cloud Platform, Terraform
You Might Be a Fit If You
- Have full-stack experience, ideally in performance-sensitive environments (e.g., crypto, fintech, gaming, real-time apps)
- Thrive in fast-paced, product-centric orgs where speed, autonomy, and ownership are the norm
- Can move independently but also communicate clearly in async workflows
- Care deeply about craft, clean abstractions, and performance
- Have strong user empathy and can translate real behavior into real product
- Have understanding of crypto and trading — and care about the details of how and why traders behave the way they do
- Want to work with other A-players — people who think like founders and ship like it
Why Join Us
- Work with a passionate team that is obsessed over product, velocity, and craft
- Ship real infrastructure that’s used by traders and degens daily — the kind of users who demand speed, precision, and performance
- Leave your mark on a product that could reshape how crypto trading is understood — not just features, but the foundation of how people will trade in the social-first, memetic era of DeFi
- It’s all greenfield — no legacy baggage, no bureaucratic blockers, just you, a fast team, and the freedom to build what you think should exist
- We’re backed by top investors and Alliance DAO, with deep ties to the best minds in DeFi
- Total flexibility — async, remote, and built for real builders who want to own their time and output
- You won’t be another cog. You’ll be a core part of shaping the next dominant trading platform
