Ares: Senior+ Fullstack Engineer (Backend-Leaning)

What We’re Building

Ares is the newest product under Fountain Platform, focused on building a high-performance social trading platform for decentralized markets.

We believe trading has evolved. It’s no longer solitary — it’s cultural, real-time, and driven by memes, narratives, and reflexive attention loops. Yet most platforms are stuck using 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 Senior+ Fullstack Engineer (Backend-Leaning) to join our team. Our engineers tackle complex challenges at the core of 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 infrastructure across the full stack — from high-performance frontends (Next.js + Tailwind) to backend systems (NestJS, PostgreSQL, Redis, and Solana RPCs)
• Build 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 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

Nest.js, Solana, Redis, PostgreSQL, Typescript, Node.js, Materialize, gRPC, Drizzle, WebSocket, Google Cloud Platform, Terraform

You Might Be a Fit If You

• Have Node.js backend 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 and 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
• Understand crypto and trading — and care about how and why traders behave the way they do
• Want to work with A-players — people who think like founders and ship like it

Why Join Us

• Work with a passionate team obsessed with product, velocity, and craft
• Ship real infrastructure used by real traders and degens — the kind of users who demand speed and performance
• Leave your mark on a product that could reshape how trading is done in the social-first, memetic era of DeFi
• It’s all greenfield — no legacy baggage, no bureaucracy, just you, a fast team, and the freedom to build what should exist
• Backed by top investors and Alliance DAO, with deep ties across DeFi
• Total flexibility — async, remote, and built for true 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
