HyperProp Amsterdam, on-site preferred (hybrid possible) Full-time Salary: €10,000 - €12,000 per month Start: as soon as possible Required: hands-on experience with low-latency trading systems

About HyperProp

HyperProp is a trading platform built from the ground up for the prop firm world. Prop firms list and sell their evaluations directly on HyperProp, and traders take those evaluations and trade them on our own platform - order entry, matching, live P&L, and rule enforcement all happen on our infrastructure.

That means we own the whole stack: the matching and execution layer traders send orders into, the real-time risk engine that enforces each prop firm's evaluation rules, and the dashboards that show traders exactly where they stand. We run 24/7, and every millisecond between order and fill is ours to optimise. We're a small, fast-moving team building the platform serious traders get funded on. Now we're looking for a Software Architect to own the technical backbone and scale it to the next phase.

The role

As Software Developer, you'll own HyperProp's technical direction end to end - from the low-latency order entry and execution path, to the real-time risk engine that enforces prop firm evaluation rules on every trade, to the dashboards traders live in. Your decisions determine whether an order fills in time, whether a rule breach is caught the instant it happens, and whether a trader's evaluation result is correct.

This role is for someone with strong opinions about system design, an obsession with latency and correctness, and a taste for fast-moving scale-ups where the founding team is one message away.

What you'll own

The full HyperProp platform: the order entry and execution engine traders trade on, the real-time risk and evaluation-rule engine, the marketplace where prop firms list and sell evaluations, payout and drawdown tracking, and the live trader dashboards on top.

What you'll do

Design and own the architecture of HyperProp's core platform: order entry, execution/matching, the real-time risk and evaluation-rule engine, the prop-firm evaluation marketplace, and live dashboards.
Build and optimise the low-latency execution path in Rust and TypeScript - keeping order-to-fill and rule enforcement as fast as physically possible.
Architect scalable WebSocket infrastructure streaming order state, fills, and rule status to thousands of concurrent traders in real time.
Design the evaluation-rule engine so each prop firm's parameters (drawdown, targets, consistency rules) are enforced live and correctly on every trade.
Make infrastructure decisions across AWS and/or Azure, including caching with Redis and database design on Supabase / PostgreSQL.
Containerise and run services with Docker, maintaining reliability across environments in a 24/7 trading operation.
Fold AI-assisted development (Cursor, Claude) into the team's workflow to ship faster.
Work directly with the founding team on product direction and technical strategy.
Set coding standards, review architecture decisions, and mentor engineers as the team grows.

Tech stack

Cloud: AWS, Azure
Database: PostgreSQL / SQL, Supabase, Redis
Languages: Rust, JavaScript / TypeScript
Domain: low-latency trading platforms, order execution, real-time data pipelines, prop-firm risk & evaluation engines
AI tooling: Cursor, Claude, AI-assisted workflows
Other: Docker, WebSockets

What we're looking for

_ 5+ years in software architecture or senior engineering roles. _
_ AI-native mindset: Cursor and Claude are a natural part of how you work. _
_ Deep experience with low-latency systems - trading platforms, exchanges, matching engines, 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.
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 every trader on the platform 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 - €12,000, paid reliably every month, for a role with founding-level impact.
Budget for hardware, tools and learning.
