About Tradesyncer
Tradesyncer is the fastest growing platform futures traders use to scale and improve their trading. Trade copying across unlimited evaluation and funded accounts in under 100 ms, plus a trading journal, analytics, expense tracking and risk management, all in one cloud-based place. No installs.
We operate 24/7 and integrate with the world's leading futures brokers (NinjaTrader, Tradovate, Rithmic, TradingView, and more) across every major prop firm our traders are evaluated and funded by. We're a small, fast-moving team building infrastructure that serious futures traders depend on every day. Now we're looking for a Software Architect to help us scale what we've built and take it to the next level.
The role
As Software Architect, you'll own the technical direction of our platform. You'll work across the full stack, from low-latency trade execution pipelines to real-time dashboards and community features. You'll make decisions that affect thousands of traders daily and set the foundation for the next phase of our growth.
This role is for someone who has strong opinions about system design, cares deeply about performance, and thrives in a fast-moving scale-up environment.
The platform you'll scale
Tradesyncer gives futures traders the full infrastructure to scale and improve, not just one tool. You'll own how trade copying, journaling, analytics, expense tracking and risk management fit together, and how it all plugs into the brokers and prop firms traders run on.
One platform, everything traders need to scale: trade copying, trading journal, analytics, risk management, expense tracking, propfirm tracker, AI coach.
Brokers and platforms: NinjaTrader, Tradovate, Rithmic, TradingView, ProjectX, Deepchart, and more.
Tech stack
- Cloud: AWS, Azure
- Database: SQL, Supabase, Redis
- Languages: Rust, JavaScript / TypeScript
- Integrations: NinjaTrader, Tradovate, Rithmic, TradingView, ProjectX, Deepchart
- Domain: Low-latency trading systems, real-time data pipelines, prop-firm risk engines
- AI tooling: Cursor, Claude, AI-assisted workflows
- Other: Docker, WebSockets
What you'll do
- Design and own the architecture of Tradesyncer's core platform: trade copier, journal, analytics, risk engine, expense tracking, and real-time data systems.
- Build and optimise low-latency trade execution pipelines in Rust and TypeScript.
- Architect scalable WebSocket infrastructure that streams fills across every supported broker and thousands of concurrent connections.
- Make infrastructure decisions across AWS and Azure, including caching strategies with Redis and database design with Supabase / SQL.
- Containerise and manage services with Docker, maintaining reliability across environments.
- Integrate AI-assisted development workflows (Cursor, Claude) to accelerate shipping.
- Collaborate closely with the founding team on product direction and technical strategy.
- Set coding standards, review architecture decisions, and mentor engineers as the team grows.
What we're looking for
- 5+ years in software architecture or senior engineering roles.
- Deep experience with low-latency systems: trading, fintech, or similar real-time domains.
- Strong command of TypeScript / JavaScript, ideally Rust for performance-critical components.
- Hands-on with AWS and/or Azure, including infrastructure design and cost optimisation.
- Solid understanding of WebSocket architectures and real-time data delivery.
- Experience with Redis for caching, pub/sub, and session management.
- Comfortable with Docker and containerised deployment pipelines.
- Familiarity with Supabase or PostgreSQL-based systems.
- Experience in or strong interest in trading: futures, prop firms, or related domains.
- AI-native mindset: Cursor and Claude are a natural part of your workflow.
- Fluent in Dutch or English.
What we offer
- Based in Amsterdam, on-site preferred, working side by side with the founding team.
- Direct impact: your decisions reach our entire trader community from day one.
- Real ownership: a small team where you own outcomes, not just tickets.
- Full platform access, plus our prop firm partnerships.
- Monthly compensation of €10,000 to €12,000, paid reliably every month, for a role with founding-level impact on the platform.
- Budget for hardware, tools and learning.
