At Inverter Network, we’re looking for a Senior Full-Stack Developer to help build our new product from the ground up. You’ll be part of a small, fast-moving team, working closely with product, engineering, and external partners to deliver a high-growth, institutional-grade product in the RWA Tokenization space.

• Type: Full-Time  
• Compensation: Competitive Salary + Equity

What you’ll do

• Lead development across the entire stack — from frontend UI/UX to backend APIs and smart contract integration— through the full product lifecycle, MVP to production-grade release.

What you bring to the table

• You’re a self-starter who thrives in fast-paced, ambiguous environments. You are ready to hit the ground running and iterate quickly.
• You’re pragmatic and product-focused: You care about the “why” behind the features you build, and strike a balance between speed and quality. You can move fast when it’s a PoC, and sweat the details when it matters.

• You have 4+ years of web3 full-stack or frontend-heavy development experience, ideally in Web3 startups or scale-ups.

• Design Knowledge:
  • You understand design tokens and know how to implement scalable design systems
  • You care about accessibility and know how to handle things like color contrast, focus states, and semantic structure when it matters
  • You’re fluent in Figma:
    • You understand its limitations and know how to interpret intent, bridging gaps when it cannot produce a 1:1 match with code
    • You know how to inspect designs in Dev Mode, understand component structure, and translate them accurately into code
• You’re experienced with event-driven or asynchronous system design; You understand queues, message buses, pub/sub, and how to build resilient flows across services.

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
